WOW. Whysynth is very cool. For subtractive synthesis

very frugal on cpu cycles. Nice. I haven't fooled much with the other
osciliator types but look forward to. I followed the suggestion (I think
:) ) at the bottum of this email regarding assigning various midi
controllers to various synthesis parameters. I added
case Y_PORT_VCF1_FREQUENCY:
return DSSI_CC(0x00);
to y_get_midi_controller at line 633 of dssp_synth.c in an attempt to
connect a continous controller that alsa sequencer shows as parameter 0.
However I get no varience of cutoff frequency. I'm quite certain that
param 0 cc messages are getting at least to jack-dssi-host. Can you
think of something I might be missing, here?
You managed to hit one of the two CC numbers that DSSI plugins are not
allowed to use to control parameters. CC 0 and 32 (Bank select MSB and
Bank select LSB) are interpreted by a DSSI host as "change program
bank", and instead of sending the CC events directly to the plugin it
should use select_program() to select a new program bank in the plugin.
If you use any other CC number it should work.
