Some hires photos of the front and back of the PCB will be very helpful. Does the noise disappear/diminish when you turn down the volume on the preenfm2

I am glad it works for you now!

Well i don't know exactly what you do, but it seems like a strange bug, since many people would have noticed it by now...

Can you load any sound as a first sound? Or only one?

Are you loading your new sound into another instrument maybe? (Which would listen to a different midi channel and hence never receive midi from your keyboard)

This sounds like you are pressing the wrong button and instead of loading the new sound you cancel the operation.

Define cheap. For about 1000 Euro or a little less you can get a Linnstrument 128 which has din-midi

The qunexus keyboards (keith mc millen) have din midi (via adapter) and a kind of MPE mode, no pitchshifting/sliding from one to the other key, but pressure and position sensors. Those are much cheaper (around 150 i guess)

But it should be easy enough to program an arduino with an usb host shield (or a teensy) to send usb-midi to serial midi output....

i think xavier misunderstood a little, because he shared code from the preenfm2 and you asked about the preenfm3, right?

the files he linked to are the source files of the firmware, so you can change things there, compile your own version of the firmware and upload it to your device. i did this many times for the preenfm2 but i yet have to setup the build environment for preenfm3.

hope this clarifies things a little.

a thought on unison.

for the near future, if voices of a patch (MPE or regular poly) is smaller then the max voice count of preenfm3 (by a factor of at least two) you could add one unison voice theoretically, no?

so for example:

a 4 voice MPE synth sound could have 4*4 voices (4 unison voices per voice) to get the maximum of 16 voices.

-unison voices don't need their own fx path, they could be added together before any filter/fx. maybe that could boost the voice count a little?

a second idea is to have a unison "fake" module. i had pretty good results with a small delay line (around 50ms) and a couple of read-heads that simply start in different positions of the delay-buffer. if you then also modulate the read-speed a little you can get pretty good results (chorus)

The oscillator section fine-tune and broad tune only work once a new note is played, changes while a note is sounding have no effect. Is this supposed to be that way? (Not strictly MPE related) for sound design it would be beneficial to have the change applied immediately.

The general pitchbend now also has the broader range of 48 semitones, not sure that was intended, but I like it. It will break existing presets though...

Nevermind, it's all good

all seems to work fine, great!

something i noticed while playing with it some more, it is really fun!

-note shift does not work when instrument1 is in MPE mode. preferred solution would be to just shift all incoming MPE channels when instrument 1 shift is used.

That is a good solution as well!!

A further comment:

I would suggest to have in the global menu, next to MPE instrument on off also the MPEpitchbend range, which is settable to 12 24 36 and 48 semitones (ithink those are the most common). And if MPE instrument is enabled, this bend range is automatically applied to o*fh, since I fail to see a MPE preset where no voice pitchbend is implemented. That is also the reason it should happen automatically, it's kind of inheritent to MPE...

Pitch MPE could still be a matrix source, for other things...


But still you are sending sysex to all devices, the preenfm2 and all other Synths connected have to check, if sysex is for them. Midi has no notion of a destination or similar, it is a unidirectional protocol. So for note information you have to use channels to send to different Synths and set them accordingly on each synth.

So you are in fact sending the sysex info to all your Synths.

Couple of things could be the issue:

-the midi stream itself is too crowded with all the sysex info, in that case other Synths that play should also stutter, did you try that?

-preenfm2 has a problem with incoming sysex that does not belong to it.

My guess is that the stream of data is just too dense, sysex was never meant as a realtime protocol to change parameters on the fly.
