Portamento don't work with chords

i've included poramento and it works fine but only at 1 voices.

If set 32 voices or playing chords it don't work.

What's my mistake? Or is it not possible?

Thanks, Dave

A few synthesizers feature polyphonic portamento (like the legendary Yamaha CS80). You can simulate that setting many MIDI2poly modules, one for every voice, but remember you have to merge them only after the conversion to mono, not in poly...

Hello, i am interested in being able to make a portmento that works with a single note as well as chords I have been able to extract the portamento module from the midi to poly, but i have been unable to make it work. What are voices, are they the same as patches? I have 3 osc sections each able to make four types of waveforms, and i have one midi to poly.

Any help will be gratefully received.

With the previous post I meant that to have polyglide, you can do that: build as many monophonic synthesizers as the number of notes you require for the chord to be played. Then you can set a transpose on every monosynth n order to obtain the chord, i.e. for major chords: FIRST synth - plain, 2ND synth +4, 3rd synth +7. But with that you've got one-finger chords. To actually play the chord on the keyboard, well it needs changing the chord type in real time and that would be a bit more complicated, since you'd need to dynamically assign voices. I'm talking about poly computation, otherwise there are several exemples of MIDI/green math modules made by oddson or exo but those work at 100hz, not samplerate: they do the process BEFORE the conversion to poly stream messages.
