WOW. Whysynth is very cool. For subtractive synthesis on linux it seems
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?
Thanks!

Yeah, addicted is right. I code in a very experimental, improvisational

I would be much more efficient!

Some really impressive specs. Are you trying to corner the market as in
"the only soffsynth you'll ever, ever need!!" :)
Right-o, as in Guinness is the only beer you'll ever, ever need,
and Gentoo is the only distro you'll ever, ever need!!
Do you have some rough statistics on number of
voices/gigahertz?
That depends on the patch. With a simple two-oscillator, single filter
patch playing 16 voices, my 933MHz Pentium 3 barely breaks a sweat
(17% CPU according to top, 22% according to qjackctl). One the other
hand, with the most expensive patch I can think of, it maxes out at
only two voices.

Heh :) Once you have done one, you are addicted.
This is not nescessarily a bad thing. Laying out a synthesizer requires
as much consideration as laying out say; the main theme for film-score.
A few cycles of scrapping and reinventing is expected, perhaps even
required. Very nice, hours of fun in there to be sure. But
how can you handle
MIDI bindings? For example, to control one of the filter resonance
knobs rather than just the MIDI note/pitchwheel in?
That's one of the things I haven't done yet, and one of the awkward
parts of DSSI. Several people (two?) have pointed out that DSSI
provides for binding MIDI CCs/NRPNs to ports ('knobs'), but the plugin
must declare these bindings to the host before the GUI gets a chance
to run. So you either have to make them hard-coded, or require
the user to exit-and-restart in order to implement custom bindings.
If you wanna hard-code your own bindings, I'll tell you how....
(Just look in src/dssp_synth.c for the Y_PORT_GLIDE_TIME binding
to the MIDI portamento time CC, follow the example, and recompile :-/)
Thanks, everyone, for your comments and questions,
