preenfm2 and preenfm3 / Re: I made some changes to PreenFM2 firmware

« on: November 10, 2026, 07:33:41 AM »

Very interesting.
I'll have to take a look at this one !!

I'm wondering how it found some free Ram to run this.
Can you have both Dexed and Preenfm2 patch playing at the same time ?

Thanks for sharing

Hey,
I totally missed this message, sorry, preenfm1 repo is here

You'll get the pre compiled firmware in the "firmware" folder.

preenfm2 and preenfm3 / Re: Preenfm2 Program Change messages only works on Bank 1?

« on: May 20, 2024, 02:05:28 PM »

Hi,

I know it's not very clear.
But from the midi doc (https://ixox.fr/preenfm2/preenfm/midi/) :

Program change
Bank select (CC#0) and Bank Select LSB (#32)
Preenfm bank : CC#0 = 0 then  CC#32 = Preenfm bank number
Combo bank : CC#0 = 1 then CC#32 = Combo number
DC7 bank : CC#0 = 2 then CC#32 = DX7 bank from 0 to 127
DC7 bank : CC#0 = 3 then CC#32 = DX7 bank from 128 to 55

So to access Bank2, program 26 you should send :
CC#0 = 0 (optional because that's the default)
CC#32 = 1 (for Bank 2, it's 0 based)

Then program change will select the preset in Bank2.

Hi,

Only 4104 bytes Sysex file are compatible. I think there are other sysex with different sizes and they won't work.
They must also have .syx extension.

256 is the max number of DX7 file you can have. Because they are pre-read and filename are in memory.

Reminder : The first FAQ of preenfm3 also applies to prrenfm2 :

Hello Xavier,
i answered about Osc.h in the PR : it's about a small cpu optimization..

I thought there were a problem.
I looked again and it looks good. Thanks

Thanks again Patrice for this new algos.
They really add something to the sound possibilities of the preenfm.
And as they are separate new algos, there's not reason not to include them

I finaly have a PR, can you take a look ?
https://github.com/Ixox/preenfm3/pull/47/

Also, let me know what you think of the commit i added on top yours.
I don't think index should be 0 when we sync. Index should correspond to the phase of the master osc. No ?
Don't hear any obvious change in most presets, but i think that could be more "hearable" when waveform are smaller.

Please confirm the changes :
. 4 New vosim (synced windowed modulation) algos
. New midi CC to control paraphonic filter (FX2)
. small adjustment to Filter2 "BODE"
Anything else i miss ?

Can you explain you change in Osc.h (i added a commment in the PR)..
I don't understand.

Thanks

preenfm2 and preenfm3 / Re: PFM3 not booting unless I press reset button on bottom of PCB

« on: February 25, 2024, 05:18:27 PM »

Nice to read its now fixed.

Without a jumper to set boot0 to GND the boot select in unpredictable.
I think a jumpter fell off, or you were lucky untill now to have it working all the time.

preenfm2 and preenfm3 / Re: PC/MAC preenfm editor 3.1.4 (Preenfm2 Unison)

« on: January 21, 2024, 06:22:42 PM »

Somehow the conexion works in the Standalone editor but as soon as i select the device in a DAW and send midi to it (tried with ableton and reaper) the standalone connexion also stop working.

Hi hupelcanel,

It should work with windows 10.

The preenfm editor open a direct connection to the midi device to to talk to the hardware.
So the standalone AND the plugin version cannot be used at the same time.

And for the plugin to work in a DAW you want to make sur that the daw does not already use the connection.
For AbletonLive for in Preferences>MIDI
And make sure "PreenFM MK2" is not used neither in input nor in output. All box must be unchecked.
Then you should be able to select "PreenFM MK2" in input and output in the plugin.

That's really cool. Thanks 

My work pulled me away from preenfm firmware the last couple of months.
It should much better in a week or so.
I cannot wait to take a look at that.
