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

@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.

Hello Xavier,
i have a github branch for this, if you want to check it out :

as the preenfm2 have not so much love these days, i did a pfm2 firmware version with the lfo shapes from the pfm3 and the 4 vosim algo as well...
it seems to work well, these features does not need much cpu nor ram.

fw attached

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.

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

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 :

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

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.

Another version :
Algo29 is reworked as it was too close to algo31 : it's now a 4 osc, with two carrier, a classic one and a synced one.
Matrix modulation is now squared for synced oscillators : sounds more natural and possibly more extreme !

Here is a new version, with another algo, which let the master sync osc to be modulated.

And i found a trick to get a much larger pitch range modulation for the slaved osc, pitch modulation from the matrix is now x 16 for those.
It helps to get the fake resonance like heard in the supercollider thread above

oh yes, i read your post a bit in hurry

yes it's worth testing : just a few components

Hi,

i used ferrite on some diy modular, i think it's good to lower EMI noise a bit, but i don't think it would be enough to clean usb power, which can be very noisy..

There is also this kind of solution for this :
https://www.audiophonics.fr/en/interface-modules/usb-20-isolator-12mbps-1x-usb-a-to-4x-usb-a-module-p-17895.html

i tried cheap chinese usb isolator, it was real junk,
the audiophonics may work, i have not tested it but it's a reliable website in my opinion.
There is other usb isolators around, but not cheap...

i should try different algo, yes algo30 is the most versatile, with its second modulator.

any idea is welcome to help finding new interesting topology

i'm still learning how to use it as well, it's a trial and error process at this stage.
i guess sidebands created by IM add new formant peaks but alone it's not enough to make a lively voice articulation, one need many matrix modulation.

For now i do simple pseudo voxy resonant thingy patch, it's fun !

Below is the patch bank i currently use, if you want to have a look.
