Ringing Call Changes
Abel can ring call changes, calling bells up or down. It can either ring a call change composition, or you can conduct call changes yourself.
Call changes called 'up'
Call changes are called 'up' if the first bell mentioned has to move up one place in the change. Thus, from
the call "3 to 4" (or sometimes, "3 after 4") will give:
Call changes called 'down'
Call changes are called 'down' if the first bell mentioned has to move down one place in the change. From
the call "3 to 1" will produce:
Note that Abel does not allow you to mix calling up and down, which is confusing to learners.
Open or closed handstrokes?
If you want to ring true "Devon-style" call-changes with closed handstroke leads ("cartwheeling"), then before you leave the Ringing Options menu, use the arrows next to the Handstroke Gap option to reduce this from 1.0 down to 0.0. If you prefer your handstrokes open, leave this set at 1.0.
Ringing a Call Change Composition
If you want to ring a call change composition, you first open the file (method collection) containing the call change composition you want - for example, there’s a file called "Call Changes.mcf" that contains a selection of call change compositions. Next select the composition from the drop-down on the left of the screen. Then click the Start button, start to ring a bell yourself if you wish, and click Go. Abel rings the composition, making calls at handstroke in the normal way. The calls are spoken, and shown on screen.
The number of whole-pulls between calls is specified in the composition. If you want the next call to occur sooner than the composition specifies, click the Bob button (or press the Bob key) - a call will then occur at the next handstroke. If, on the other hand, you want to delay the next call, click the Plain button (or press the Plain key); this can be useful if you’re confused about where you are.
Conducting Call Changes
If you want to conduct call changes, turn on Manual Call Changes in the Ringing Options dialog, see above: click "On" in the Manual Call Changes box. Also choose whether you want call changes to be called up or down, then click on OK.
When you have turned on call changes, click on the Start button to set the bells ringing rounds. Now, click on a bell. This is the ‘active' bell - that is, the bell that is being told to move (the first one you would mention if you were calling this in the tower). So, if you click on the 3 and you are calling ‘up' you will cause the 3 to ring after the 4. If you're calling down and click on the 3, it will ring after the treble.
Abel doesn't give you a verbal prompt for a call change you called yourself - after all, you know when you clicked it! Just as in the tower, the change takes effect at the handstroke following the call.
You can if you like click on several bells in one change. This only makes sense if it produces a logical end result - if you're calling up and from rounds click on 3 and then click on 4, you end up back where you started from (think about it)! But if you click (quickly) on 2, 4 and 6 then you can get from
in one change.
You can ring a bell yourself with call changes selected, but you must choose your bell by clicking on it BEFORE THE ROUNDS START. Once rounds have started, Abel uses mouse clicks to mean 'do a call change'.
To avoid some very strange effects, call changes are ignored if a method is ringing.
NOTE: when you've turned on call changes, clicking on a bell during the ringing causes a call change. With call changes turned off, clicking on a bell rotates the bell circle (it always does this when the bells are not ringing). Don't get confused!
