I want to create a "synth" in kyma with a mono / poly button - a button to change between monophonic and polyphonic modes... and I'm having trouble trying to do it.

The MidiVoice sound has a polyphony parameter, but it's a compile time parameter so I can't put a hot value in it.

I tried creating two midivoices, one with a polyphone of 1 and the other with a polyphony of 10, then I'm using a button on the VCS to set a hot value in the Left and Right parameters to effectively switch between the two midivoices.

The problem I'm getting is when I switch to the monophonic midivoice I'm only hearing a note every 11 key presses (over midi). I've tried all combinations of the Shared parameter in both voices and it makes no difference.

Also when I select the polyphonic midivoice it plays 10 notes fine but then skips the 11th.

Am I doing something silly? Or is it not possible to have two midivoices in the same sound?

Thanks for any help!

Welcome!

One solution that might work is to copy your entire sound structure to the left of the midi voice prototype and paste it in your second midi voice (the poly) this way you have two complete parallel and identical copies. Place two gain modules, one for each midi voice output and use a hot parameter to simply switch the gain from - infinity on one channel and to zero on the other.

in one gain module you put : !VoiceType and in the other : (1-!VoiceType) abs "absolute value" and make sure the hot parameter !VoiceType is a switch.

This is a brute force type of solution but can keep you moving forward.

Another work around might be to have the mono midi voice prototype on one midi channel and the poly on a separate channel and switch midi channels via the keyboard or daw? not sure if that is convenient for your performance setup.

Also if you post your sound here others can have a closer look in case you have run into some other issue.

I made these suggestions as it sounds like you have run into a conflict as both midi voice modules are fighting over the data stream - sorry not at kyma to test it out and this is just a guess

HTH

BTW you will need to modify my first solution's expressions with a scalar in the gain modules

Thanks for the welcome!

I think I've done pretty much what you suggested. I used the Left and Right parameters in the Midivoice to fade between them instead of using a gain module but the principle is the same.

I've attached the sound.

Both midivoices are sharing the midi stream in an unhelpful way so the "mono" voice is only getting a midi event once every 11 notes.

thanks,
