Right. But if the trumpet patch you use doesn't support polyphony (because hey - it's a trumpet), then these two are the same, regardless of your intentions. > Yes I agree, a piano patch, fed a non-challenging score could figure out > which voices to allocate. > A guitar however can't, each string supports an overlapping range of > pitches, each string is independently bendable, power-chords > deliberately use the same pitch on two strings. > > A guitar-synth needs explicit help allocating pitches to the correct > string... We've already established that guitar synths are special, and a reasonable answer is to do 1 string per channel. > The musician can switch-off keyboard-style VVID allocation. > > He should have a range of possible VVID assignments schemes including: > -keyboards score mode > -solo score > -one-voice-per-note-in-the-score-mode OK. I think already said this, but this sounds fine to me. The host can provide this explicit VPID re-use (as a feature). This isn't part of the spec, I think, but a good thing to have worked out. Tell me if this sounds right, just as an example, sticking with the above use case: This score requires a solo trumpet. The host sequences notes that are explicitly tied together, somehow. The user explicitly connected the notes. Note-on VPID(0) G4 Note-on VPID(0) G4 Note-on VPID(0) A4 This score requires a trumpet trio. The host sequences individual notes.

This is the only thing I disagree with - re-using a VPID is a suggestion to the plugin about the relationship between voices. The plugin can choose to re-use the real voice or not, as it makes sense. The example trumpet synth above would choose to re-use voices with re-used VPIDs. Does that taint your model too much? I'm still working on an animation. > thockin@xxxxxxxxxx wrote: > >On Sat, Dec 03, 2005 at 06:56:41PM +1300, Jeff McClintock wrote: > > > >>floorf(pitch) on the 2nd note to determinin which (real) voice to steal. > >> > >>What if I'm using a micro-tonal scale with say 24 pitches per octave ( > >>0.5 semitones per key). > >> > >>Won't your scheme steal the wrong voice? > > > > > >It might, but if you are using a microtonal scale you sould have to > >substitute your own function for floorf() to round to the nearest pitch. > > > > > >>Isn't the easiest solution to re-use a VID? > >> > >>Note-On VID 0 G4 > >>Note-On VID 0 G4 > >>Note-On VID 0 G4 > >>Note-On VID 0 G4 > > > > > >Again, this solves *this* problem but breaks the truly polyphonic mode of > >operation.
