hello Maki,

i'm not sure how to do it on the pfm2 but some inspiration can be taken from the MI midipal
https://github.com/pichenettes/midipal/blob/master/midipal/apps/dispatcher.cc

The midipal manual :
https://pichenettes.github.io/mutable-instruments-diy-archive/midipal/manual/#dispatcher-dispatch

inp   5

Input channel.

mod cyc

Dispatching method

• cyclic (cyc). Each new note is cyclically played on the next channel.
• polyphonic (pol). The mapping of notes to channel uses a true voice stealing algorithm. The MIDIpal tries to reuse the same channel for occurrences of the same note ; or the least recently used channel.
• random (rnd). Each new note is routed to a random channel.
• stacking (stk). Each note is sent to all channels at the same time. Perfect for thickening a lead by sending it to several synths, or to several parts of the same multitimbral device.
• velocity (vel). The louder (higher velocity) the note, the higher the MIDI channel it is sent to.

num   3

Number of output channels. For example, if out = 4 and num = 3, the notes will be dispatched to channels 4, 5 and 6.

Could you make only the basic one: Each new note is cyclically played on the next channel?

[Toltekradiation]

mmh, it may not be as simple as it seems, i fear, but why not getting a midigal to do this, and then more !

Midi gal must be made from scratch and Preenfm2 is already made.

[Toltekradiation]

Maybe a simple puredata patch would be suitable for the job,
i did a quick one, which cycle input notes to midi channel 1 to 4, here is a screenshot :

Can Preenfm2 load pictures of PD patches? Why a limit of 4?

[Toltekradiation]

nope, https://puredata.info/
just change the value on the [poly] object in the patch, from 4 to 16.

I think you are the only man on the planet who can convert PD graphics to PreenFM2 matrix!  Mididispatcher is waiting for you to release its power on the Preenfm2.

i feel it a bit weird to do such job from a synth.
Don't you use a sequencer ? i think it should be sequencer's job.

[maki]

Yes, it is both wierd and innovative. To play a set of monophonic synth as a polyphonic synth from a very modest fm box. Or to treat several midi channels as several monophonic lines from an external midi controller. I have never seen such a concept before. It would be beautiful.

@maki,
here we go, i did a pfm2 fw with midiPal dispatcher code (almost), so there is now 4 dispatcher modes available from Tools/Set menu : Cyclic / Poly / Random / Velocity
You have to set the dispatcher base channel and range.
For example, with base channel 3 and range = 4, midi is sent to 3,4,5,6 channels.

I have now a good reason to keep my pfm2 on the desk, it was gathering dust, which was a shame.
It is fun in duo with a pfm3 !

fw attached.

Could you make a mode where only the last dispatched channel transmits Pitch Bend? To emulate realistic string-bending.

[Toltekradiation]

it sounds like you want a mpe controller implementation, which is out of the scope of the midipal :/

[maki]

Could this help?
