I will look into this as well as it should be possible and would clean up 
the interface considerably.

I recently bought a USB keyboard, it works here with aconnect but that is 
because I do not always run jack. I am pleased to know that qjackctl works 
though.

>No response to pitch-bend or mod-wheels, it seems.

Funnily enough I uploaded -66 yesterday night. If fixes a number of issues I 
found from linking up the USB keyboard. Pitch bend was broken, it should now 
be fixed. The Mod wheel should work, in as much as I link it to CC #1, but 
some of the synth patches will not respond to Mod - depth and effect are 
sometimes controlled by the synth settings. If the Mod does anything then it 
should be audible from the GUI mod wheel. If that does anything but the 
synth mod wheel does not then it is a bug. At the moment bristol will not 
remap CC to controls, which means the fix is probably something I have to 
do.

I am working  on code to allow you to link arbitrary CC into bristol 
controls, and to give more GM-2 support, but that is a little way off.

The other things that was broken is keyboard assigment and release - note 
on/off can intermittently be lost. I was surprised by this, not just that it 
happens but also that it was so pronounced. It turned out to be an issue 
that I never saw with a standard MIDI interface, I could read note messages 
and apply them faster than MIDI could deliver them at 31.25KHz. The USB 
interface is considerably faster, so my code, which only executed one note 
message per 'select()' could fail. This is an odd interface to the ALSA SEQ 
but was easy enough to fix once the penny dropped.

Work is going on to change a lot of the MIDI code. Sustain does not work in 
-66 (although that was fixed last night), programme change is not 
implemented but is high on the list and loads of other stuff.

Regards,

Nick.
