Hi All,

I've just checked in a new version of the Virutal Keyboard.  This
version allows for custom keyboard map definitions to be create.  In
CVS I have added a documented example keyboard.map file in the
InOut/virtual_keyboard directory.

Regarding the latest:

-the ability to change Banks has been added, and the program change
spinner has been replaced with a dropdown box.  The bank box is
populated by default with 128 banks (midi 0-127) with names "Bank 1",
"Bank 2", etc. The program change box is by default populated with
General MIDI instrument names.

-with a keyboard.map (supplied via the -M flag, so -Mkeyboard.map
instead of -M0), one can define the names of banks and what bank
number they correspond to, as well as program names and numbers for
those banks (please see keyboard.map file for documentation)

-While the default for banks is 0-127 (in MIDI), the support is there
for 0-16383 to support the MIDI spec.  Bank changes are split into MSB
and LSB when sent as controller values to get the 14-bit resolution.
If you're programing against raw midi controller values, you can
probably ignore the MSB and just use the LSB which will give the 0-127
as most probably won't even use so many banks.  Just for reference,
bank changes are transmitted as controller changes with controller
number 0 for the MSB value and controller number 32 for the LSB value.

-the keyboard was completely redone yesterday so that things will be a
bit more user friendly; if you are on a channel and change the bank of
program, then change channels, when you come back it will return to
the bank and channel settings you had before; if you change programs
for a bank on a channel, then change banks, then come back, it will
return to the program you were on previously  (this all had to be
redone for the custom mapping as different banks may not have 128
defined programs to show in the UI)


I have not done stringent testing of the bank changes, but my simple
tests here show that channel and program changes work correctly.

I think things are fully working, but will go now to do a little more
testing and see if there is any memory leaks.

Thanks!
steven
