The author would be pleased to receive feedback on Handbell Manager, and will attempt to assist users with problems if advised by email.
· Abel (from www.abelsim.co.uk) or Beltower (from www.beltower.co.uk). Versions 3.7 and later of Abel and versions 10.27 and later of Beltower included specific enhancements for use with Handbell Manager. Ringing Room (www.ringingroom.com) and Muster (drichards2.github.io/muster).
· Microsoft Windows XP, Vista, 7, 10 (other versions of Windows will also work if USB support and .Net Framework are available)
· Microsoft .Net Framework (from www.microsoft.co.uk)
· One to four USB motion controllers. Handbell Manager has been tested with the wired and wireless (“FriiHand”) motion controllers manufactured by ActionXL (now no longer available). Other joystick devices that generate a movement signal in an X, Y or Z axis will also work with Handbell Manager. In 2020 a group of ringers developed eBells, which look and feel like real handbells, but are 3D printed in plastic and contain USB motion controller electronics (ebells.changeringing.co.uk).
· Ringing Room requires Chrome or Firefox as the browser (not Internet Explorer or Edge).
· Muster requires that both the latest version of Muster and either Abel or BelTower are installed.
1. Download and run HMInstall.exe from www.changeringing.co.uk/handbellmanager to install Handbell Manager.
2. Plug in your motion controllers.
3. Run Handbell Manager.
4. Press the buttons on the controllers. If working correctly, the on-screen counts will update with an orange highlight to show the stroke, and which buttons are being pressed.
5. In Handbell Manager’s menu, click on Run – Choose Simulator and click on your simulator software (either Abel, Beltower or RingingRoom).
6. Either Run – Abel and
· In Abel’s menu select Options – Ringing Options and check the option Bell Keys: up/down action.
· If you have Abel version 3.6.2 or later, uncheck the option Bell Keys: with Start.
· Check that the bells sound if you press the “J” and “F” buttons on the keyboard.
· If you have an earlier version than Abel 3.9.2 then the Handbell Manager configuration settings will need updating as follows: In Handbell Manager select Tools – Options – Abel Settings, amend ChildWindowClassName to “AfxMDIFrame80s” and GrandchildWindowClassName to “AfxFrameOrView80s” and press OK to save the settings. Note: the Default Settings button will revert these changes.
Or Run – Beltower and
· Set the following options in Beltower’s Options – Ring Options:
o Multi keys to “JF” for two bells or “JFRU” for four bells and Ringers’ Bells to the bell numbers corresponding to those keys.
o Timing Options to Hand Bell Sensor(s) with Animation
· If you have an earlier version of Beltower than 10.27, in Handbell Manager’s Options – Beltower Settings, change Buttons 1 and 3 from “¬” to “F5” (Start).
· Check that the bells sound if you press F5 then “J” and “F” buttons on the keyboard.
· An option worth trying is Co-operative Timing, as following bells will hold up for you to ring. To use it, you will also need to untick Auto-strike + Animate, tick Animate on Input, Hand/Back Alternate, and tick Flip Handbells in Animation Settings.
· From Beltower version 11, there is a new Timing Options preset called 'Hand Bell Sensors with Animation and Co-opTim' to provide the ideal selections for Handbell Manager. In addition, the spacebar can be used as an alternative for Start/Stop, and any call key (BSOERT) can also be used as a Go button.
Or Run – RingingRoom and
· Handbell Manager will start a Ringing Room session using your default browser, which needs to be Chrome or Firefox, not Internet Explorer or Edge.
· Assuming you are already registered with Ringing Room, enter your Tower ID and name as usual. Click in the Ringingroom window. If you have motion controllers set up, you should now find that moving the motion controllers will cause Ringing Room to respond to your assigned bell(s).
Or Run – Muster and
· Handbell Manager will start Muster. If Abel or Beltower is not already running, start it.
· Click in the Muster window. If you have motion controllers set up, you should now find that moving the motion controllers will operate the bells in Abel or Beltower via Muster.
7. Hold the ActionXL wired controllers like the handles of handbells, with the buttons facing upwards underneath your thumbs and the wires pointing towards your wrist, or turn on the ActionXL wireless controllers and hold them in the palm of your hand with red light horizontal and pointing forwards. Swing the controllers like handbells.
8. If your controllers aren’t recognised or the bells don’t ring, check out the troubleshooting section.
9. If your bells ring, but not when you want them to, check out the calibration section.
These enable you to set up a desktop shortcut that is already set for a particular use of Handbell Manager e.g. one shortcut for Handbell Manager + Abel and another for Handbell Manager + RingingRoom.
When you create a short-cut by right-clicking on HandbellManager.exe (in your installation folder) and selecting "Send to Desktop", a desktop shortcut is created. Now, you can modify the settings of this shortcut as follows.
1. Right-click the shortcut and select "Properties".
2. Click in the text box called "Target:", then hit the "End" key. The cursor will move to just past ".exe".
3. Place a space character followed by the following:
-s 0 -r To select Abel and automatically start Abel.
-s 1 -r To select Beltower and automatically start Beltower.
-s 3 -r To select RingingRoom and automatically start a web-browser session. You will then need to enter the tower name or ID into RingingRoom (unless you use a shortcut for that; see below)
-s 4 -r To select Muster and automatically start the muster app.
Note: if you want to set the URL for RingingRoom in the shortcut you can use -u <ringingroom URL>: e.g.
-s 3 -r -u www.ringingroom.com/mytower (where "mytower" can be your tower name or an ID number)
For starting Muster via the shortcut, the "Target" text would now look something like:
C:\HandbellManager140\HandbellManager.exe -s 4 -r
4. Click OK to close the Desktop Shortcut properties dialog.
5. Rename your shortcut if you like by right-clicking and selecting "Rename".
If you plugged in your controllers prior to starting Handbell Manager, you should see a panel appear as shown below. If you plug in or remove your controllers after you started Handbell Manager, you will need to press the Check for Controllers button to find them. The handbells are shown right to left, to match the clockwise arrangement of the bells on your simulator’s display.
Handbell Manager counts each handstroke and backstroke and press of a controller button, and highlights in orange which stroke the bell is currently at. The button counts will also show in orange when they are pressed. These counts can help you determine whether the bells are configured properly. If you press the Reset Counts button to zero the counts, then swing a few handstrokes and backstrokes with each bell alternately, you should expect the counts to be equal to the number of strokes you rang.
If they appear to be functioning as expected, then it is worth trying them out with the simulator before changing any options. To start your simulator, you can click Run on Handbell Manager’s menu, or start it in the usual way.
This dialog window needs to remain open while you are using the dummy handbells, but you can move it or minimize it to hide it.
Handbell Manager has a number of tools to help you configure your dummy handbells for the best possible operation. These are described in the following sections.
To help fine calibration of the controllers, Handbell Manager provides a Monitor (Tools – Monitor) which shows a graph of the handbell movement in real time. Each handbell is shown in a different colour. Two horizontal lines are drawn in the same colour as the respective handbell to show the point in the swing where the clapper strike is triggered. When the handbell’s position crosses these lines, Handbell Manager determines whether and when the bell will strike. For example, it will only strike a backstroke after a handstroke and visa versa. Also, it will not initiate another stroke within the debounce delay period. This prevents unwanted strokes being triggered while the controllers stabilise after a sudden stop, such as if you hit your hand on your knee. In addition, there is an option to introduce a strike delay for fine tuning of the handbell. When Handbell Manager actually issues the keystroke to Abel to strike the bell, a vertical line is drawn on the monitor showing the timing of the clapper strike.
The monitor can be frozen and unfrozen by pressing the F3 Key, or by right clicking and selecting Freeze from the context menu. Options are also available on this menu to turn any of the monitor lines on or off.
Most users should find the default calibration satisfactory for ActionXL wired controllers, since it has been chosen to reflect the dynamics of the clappers of real handbells, and normal handbell usage. Try the controllers with the default settings for a while before attempting any changes to reflect your own ringing style.
If changes are required because the bells don't sound at the right times for your style, select Tools – Options from the menu to show the settings dialog. The first tab contains the handbell calibration options.
If the backstroke sounds too early/late then make the backstroke calibration value more/less negative, by manually typing in the Backstroke strike position box below each bell. If the handstroke sounds too early/late then increase/reduce the Handstroke strike position in the same way. Any changes made to values will be effective immediately so you can try the bells and continue fine tuning.
Once you are happy with the settings, click on OK to permanently save them, or Cancel to revert to earlier settings. If you wish to revert to Handbell Manager defaults for all options (Handbell Calibration and Abel/Beltower Settings), press the Default Settings button.
If you wish to calibrate your controllers, select Tools – Options from the menu to show the settings dialog. The first tab contains the handbell calibration options. The screen shows the current axis (tilt position) of each controller as values between -2048 and 2047. Negative values occur when the buttons are on the upper side of the controller and positive ones when the buttons are on the lower side, and are zero when the controller points either upwards or downwards.
The ActionXL motion controllers use tri-axis accelerometers to determine their position and are factory calibrated to 2g. Handbell Manager is only using one axis to determine the up down swing of a handbell. When you tilt the controller to its upper or lower extreme, it has only moved half as far as it can (because the Earth's gravitational pull is 1g, half of the maximum). In motion higher Z-values will be recorded, particularly on the downswing where the acceleration is in addition to the pull of gravity.
An option to change the Handbell swing axis has been included for experimentation with different controllers, or more unusual handbell swing actions. In the case of the ActionXL controllers, the Z-axis is up/down, the X-axis is left/right, and the Y-axis is back/forward. The remainder of this section assumes that you are using the default i.e. the Z-axis.
For dummy handbells to function reliably, the strike positions need to be set close enough together to ensure that the controller will trigger them even if they are swung very gently i.e. they must be within the range of the resting positions at handstroke and backstroke. The strike positions can be close together towards the middle of the swing, but the backstroke Z-axis position must be a lower value than the handstroke position, unless you wish to use the controllers upside down, in which case the handstroke will be the lower value. Handbell Manager uses this difference to distinguish handstroke from backstroke.
Each bell has a Calibrate button that helps you capture a backstroke and handstroke strike position by holding the controller in the position you want and pressing a button. Note that you can hold the controllers either way up (e.g. buttons facing down, if this is more comfortable) but you must calibrate them as you intend to use them as the Z-axis position for handstroke and backstroke would be reversed, and will have a different sign and size.
When using the Calibrate buttons, the controllers must be held completely still when the button is pressed, because any movement or jolting will result in incorrect calibration. Also, do not calibrate the controller with it held below a horizontal position (This is because the controller interprets angles below the horizontal identically to those above the horizontal.)
As an alternative to using the Calibrate buttons you can manually type in the Z-axis position in the Handstroke and Backstroke strike position boxes below each bell. You may find it easier to start with the default values as shown above, then manually fine tune the values up or down in increments of ten until your bells strike at the desired position. You can have the monitor window open while you are making these changes to show visually what effect the changes are having.
If the bells are striking too late, you need to adjust the strike positions to be closer to one another (i.e. earlier in the swing), by making small adjustments to the numeric strike value, or by pressing the Calibrate button to set new values. Also ensure that the Handstroke strike delay and Backstroke strike delay are set to zero. Changes are effective immediately, so you can keep ringing the bell to see whether you are getting the desired result.
If the bells are striking too early then there are two options. First try adjusting the strike value. If the bells are still striking too early, you can then introduce a Handstroke strike delay or Backstroke strike delay by setting an appropriate value in milliseconds. Note that the same delay will be applied to all bells.
Handbell Manager will not strike the same bell twice before the Debounce delay period has passed. This prevents multiple strokes occurring in quick succession when the controller signal bounces after a sudden stop. Experience has shown that 350ms is a good value to cure this problem, while still allowing you to ring the bell twice in a second.
The settings for controlling your simulator software can be configured using the Tools – Options – Abel Settings, Beltower Settings, RingingRoom or Muster Settings tab; the relevant simulator having already been selected from the Run menu. Handbell Manager works by sending messages to the simulator as though you had pressed the keys on the keyboard. The keys to be pressed by Handbell Manager can be changed here.
The key for ringing each of four bells is initially set to the default used in Abel (J, F, R & U). Beltower can be configured to use the same keys. However, if the keyboard mappings have been changed in your simulator, they have to be changed in Handbell Manager to match.
The buttons on each controller can also be configured to trigger simulator functions, such as Start, Go, Rounds, Stand, Pause, Bob, Single etc. As well as individual keys, you can also type “F1” to “F12”, “Esc” or “End” to operate the function keys.
eBells and the ActionXL wired controller have a Left (1) and Right (2) Button. The ActionXL “FriiHand” wireless controller additionally has an Upper (3) and Lower (4) button on the nose of the controller. Handbell Manager button defaults are:
1 & 3 (Right hand)
2 & 4 (Left hand)
1 & 3 (Right hand)
2 & 4 (Left hand)
Left button (1):
Right button (2):
Upper button (3):
Lower button (4):
To prevent your dummy handbells and simulator getting out of sync (e.g. you bell is at handstroke and the simulator is displaying the bell at backstroke), you can use the up/down keyboard action in Abel. With this option, Abel and Handbell Manager cannot get out of sync as a keyup is used for a handstroke and a keydown for a backstroke. The Use bell keys up/down action must be ticked both in Handbell Manager and in Abel (under Abel’s Options – Ringing Options) for this to work. Conversely, both should be unchecked to use normal keystrokes.
The Process Name is the executable name for the version of Abel or Beltower you are using e.g. Abel3 or Beltow95. It is the name of the executable file without “.exe”. This is also the name of the shortcut to Abel you should place in Handbell Manager’s installation folder (“C:\Program Files\Handbell Manager” is the default location) to allow it to be started from Handbell Manager’s menu. You may need to be logged on as an administrator to access Program Files folders.
The ChildWindowClassName and GrandchildWindowClassName are required so that Handbell Manager can pass keystrokes to the correct window in the respective applications. Default values are provided, but these may need to be amended for different versions of the simulator software. For example, these values changed from “AfxMDIFrame80s” and “AfxFrameOrView80s” to “AfxMDIFrame140s” and “AfxFrameOrView140s” respectively in Abel version 3.9.2.
Handbell Manager cannot identify controllers uniquely and stores the configuration settings by handbell number. If on subsequent use, controllers with different configuration characteristics are identified in a different order by Windows, the controllers may not be assigned to the same handbell. To overcome this problem, choose Options – Assign Controllers from the menu.
In the example above, another joystick is connected and was automatically assigned to Handbell 1. By clicking on this controller to highlight it, and clicking the green down arrow twice, it can be reassigned to handbell 3, or not to a handbell at all had four other controllers had been active. The two motion controllers appear identical, but could have different calibration settings. These could be swapped by clicking on the second one and clicking on the green up arrow to move it up the list.
Some possible reasons for problems are listed below to help with troubleshooting.
Cannot run Abel, Beltower or Muster from Handbell Manager
· Shortcut not present or its name doesn’t match the process name in Abel/Beltower Settings. Create a new shortcut to the Abel/Beltower executable and copy it into Handbell Manager’s installation folder. Rename it to the Abel/Beltower Process Name (e.g. “Abel3” in place of “shortcut to Abel3.exe”).
· Shortcut not setup correctly to run Abel/Beltower. Confirm that it works if you double-click it.
No Motion Controllers Found
· Only Windows recognised motion controllers are fully supported.
· eBells and ActionXL controllers are plug and play devices, so installation is automatic. Windows should recognise them as a game controller. If they are being recognised as a generic joystick or are not being recognised at all, then there is a configuration problem in Windows.
· https://gamepad-tester.com is a useful website to confirm that your controllers have been identified appropriately.
Bells do not ring
· The appropriate simulator is not running. Check that the bells ring when the simulator is used with the keyboard.
· For RingingRoom, its browser window must be kept in focus.
· More than one copy of the simulator is running. Close all but one instance.
· Handbell Manager is not running.
· The wrong simulator is chosen in Handbell Manager. Reselect using Run – Choose Simulator.
· The Process Name in Handbell Manager Tools - Options - Abel Settings or Beltower Settings is not the same as the instance of Abel/Beltower that is running, or the ChildWindowClassName and GrandchildWindowClassName are not correct for the simulator’s version.
· The keyboard mappings for the bells in Handbell Manager don’t match the simulator’s keyboard mappings.
· The option Use bell keys up/down action setting is not the same in both Handbell Manager and the simulator.
· The backstroke and handstroke strike positions are set too high or too low.
· The wrong Handbell swing axis is being used (should be “Z” for ActionXL controllers).
· The controllers are not assigned to the correct handbell. Use Tools - Options – Assign Controllers to change.
· Wireless controllers are not switched on, are not communicating with the correct dongles, or the batteries are flat. Remove a battery to fully reset.
Buttons do not work
· The keyboard mappings for the buttons in Handbell Manager don’t match the simulator’s keyboard mappings or Function Keys.
· Wireless controllers are not switched on, are not communicating with the correct dongles, or the batteries are flat. Remove a battery to fully reset.
Bells strike too late
· Backstroke and/or handstroke strike delay are not set to a low enough value. Set to zero.
· Strike position is set too late in the swing. Fine tune by making small adjustments to the strike values.
· Incorrect calibration. If using the Calibrate button, hold the controller absolutely horizontal for the backstroke strike and absolutely vertical for the handstroke strike, then make fine adjustments manually to the strike values.
Bells strike too early
· Strike position is set too early in the swing. Fine tune by making small adjustments to the strike values.
· Incorrect calibration. If using the Calibrate button, hold the controller absolutely horizontal for the backstroke strike and absolutely vertical for the handstroke strike, then make fine adjustments manually to the strike values. If the bells still strike too early, use the backstroke and/or handstroke strike delay.
Bells strike erratically or multiple times
· Debounce delay too small. Set the debounce delay to a value that eliminates multiple strikes (e.g. 350ms).
· Backstroke and handstroke strike positions are too close to one another. Recalibrate.
· Controllers are upside down, and have not been calibrated for upside down use.
· Inconsistent handbell swing. Swing the controller so that the arc it makes is in the vertical plane that is in line with the wire, and the upper flat side (with the buttons) is always approximately perpendicular to the vertical plane. Although other motions of the controllers can make the bell sound, the calibration may not be correct.
· More than one copy of a simulator is running. Close all but one instance.
Simulator pictures are at the opposite stroke to the controller
· Hold the handbells at handstroke and press F4 to reset Abel bells. This problem can be eliminated if the Use bell keys up/down action is checked both in Abel and Handbell Manager. Warning: Although you can get the handstrokes and backstrokes back in phase by turning the dummy handbells over, this disrupts the calibration and the striking points will be incorrect.
· For Abel or Beltower, type “J” or “F” on the keyboard to switch the stroke of the bell independently of the controller.
Bell is ringing but Abel images are not rotating
· Hold the handbells at handstroke and press F4 to reset Abel bells.
Error message displayed when Handbell Manager opens or saves settings
· Settings file corrupt, or an incorrect version. Delete it and it will be automatically recreated with the default settings.
· Incorrect file access permissions. Handbell Manager is designed to work under Windows with standard user access permissions. Check that you have read access to the installation folder and write access to the user’s application data folder.
Motion controllers don’t feel like handbells
· The motion controllers are too small and light. Try attaching the controllers to pieces of wood, or to the handles of handbells with the clappers removed.
· The ActionXL wireless controllers are larger and heavier than the wired controllers.
· eBells are designed to look and feel like real handbells
