Not that we are dying to see MusE 1.0, but err ... in fact would be very happy
to use it !!!! ;-) When, when !? :)
Well, for the Freq/resonnance question, its a thing i wanted to do as well in
I asked the author of swami if ever it was possible to use midi cc to control
Filter cutoff. The answer is that you have to edit your soundfont to define
Go in the "modulator editor" window (View Menu), and add one. Then manage to
affect it to the Cutoff/Rez. The modulator can be a midiCC or other thing, if
i remember well. You can try with the modwheel for a quick live test with
your midi keyboard. Then program a sequence in Muse.
I am not sure if MusE is implementing well the fluidsynth engine and if the
midi messages sent will effectivly have an action, BUT, as a workaround you
can use the real stuff, i.e the external "fluidsynth" program (via QSynth,
its GUI stuff) and record the audio with jack. It should work !
On the other hand, may be there is a more direct way to do that using NRPN on
any soundfont, preventing the need to do special programming with swami. Sure
it would be good to know.
