preenfm2 and preenfm3 / Intermittent button misfire behavior - any thoughts?

« Last post by Marto on August 19, 2026, 10:44:14 PM »

I recently bought a PreenFM3 used. The seller had built tis unit himself.

I have noticed a intermittent misfire issue with button #1 of the bottom left 6x button matrix.

Every few presses it does not trigger.

Observations:
- I have turned the unit on approx 6 times over various days - sometimes the issue is there, sometimes not. 50/50
- If I tap very far to the left of the button, there is none
- Tapping to the centre or right of the button results in misfires.
- I tried a whole combination of different ways to press it. Momentary or long presses, same result.

Has anyone experienced this behavior and if so, do you think this is a software or hardware issue?

Maybe someone can suggest some things to try.

Thanks so much for reading

preenfm2 and preenfm3 / Where to find patch banks for the PreenFM3?

« Last post by Marto on August 17, 2026, 05:59:35 PM »

Hi there,

New to PreenFM3 and new also to FM in general.

I was looking around for patch banks for the PreenFM3 to see the capabilities and see how they work. I wouldn't know where to begin to program my own patches.

I found a small few dotted around this forum.

Is there an all in one spot to find groups of these patches?

I was looking in particular for PreenFM3 specific ones that make use of the inbuilt FX, if they exist? (Not looking for DX7 ones.)

Thanks in advance for any leads here .

preenfm2 and preenfm3 / Re: Preenfm3 bank & midi list

Hi David. I am new to the forum and I don't see an attachment, maybe as the post is older it disappears? Perhaps you could re-attach?

Hi,

I assembled the Preenfm3 two years ago, and it was my first experience with hardware FM. As I prepared myself tables with CC values, NRPN (documentation for the preen is its Achilles' heel) and a general template it began to open up for me.

Sound bank - you won't find ‘classic’ FM sounds here. No bells and whistles (pun intended). I tried to step out of DX7/pads/pianos comfort zone a bit. There are some decent (IMHO) Kick presets .Some bass, leads, drones. A few presets made for a joke, because why not. I don't play keyboards, I use sequencers. This is made mostly (except for the drones) for fast 1/16 & 4/4 kick & offbeat hh paterns. Added some overview info, sometimes it's worth playing with env, lfo, IM, find a good octave...

In attachments - MidiCC list, NRPN tables (my audio workstation is without internet and I won't keep searching github or doing math equations to find what LSB value I need), value template, .bnk bank.
Have fun, maybe some preset will suit someone.

Maybe scala tuning is weird by essence, i asked your question to chatgpt and the answer was quite confusing
Scala rabbit hole...

Toltekradiation: I think I had mistakenly deleted the final line
2/1
because I was experiencing a different issue where the preen was repeating the notes when hitting the next octave.
When I look at your scala.zip flie, I see your reg_22 TET Porcupine[7] 3 3 3 4 3 3 3.scl file has 2/1 at the end. I will try again with the correct file and see what happens.

I also see this 22-TET porcupine[7] file in another folder of scala files:

! 22-TET Porcupine[7] 3 3 3 4 3 3 3
Porcupine[7] generated inside 22-TET
8
0.000000000
163.636363636
327.272727273
490.909090909
709.090909091
872.727272727
1036.363636364
1200.000000000

Wouldn't this also incorrectly repeat the octaves?? There seem to be a lot of weird issues with people not understanding the file format (including myself obviously)

preenfm2 and preenfm3 / Good resource for presets?

« Last post by Jdom on April 17, 2026, 09:24:16 PM »

I thought I found some. But now I cannot. I like having a bunch of cool presets to start with. Any one knows a good place to download some for my preenfm3?

Hi all, I know this forum is not super active (and neither am I), but I just wanted to drop a note that the news of PreenFM being discontinued inspired me to submit something made with the PreenFM3 to weekly beats. If you're interested, find it here: https://weeklybeats.com/wahsp/music/supreen

This is nice mate
