PreenFM2 / Re: Latest firmware : 2.09 (2018 October 28th)
« on: December 12, 2018, 08:42:38 AM »

Maybe in some (rare) case having midi channel in combo would be usefull but i'm sure i'll have much more problems with people reporting it stops working because they don't send the midi channel of the combo.

Regarding the FLUSH it's used all the time by the plugin, so i think it works. The flush is done whatever the nrpn value is.
No it's not for USB only, should work with DIN5 midi.


PreenFM2 / Re: Yellow OLED : high frequency solution

EDITED : i thought it was a blue OLED. Seems like it's a yellow OLED in a blue metal box ;)


I have a blue OLED and it makes lots of noise (not the 13.5Khz noise though), unfortunately i don't have a solution for the blue OLED.
The only solution you have if you cannot modify the hardware is to have a look at the noise with a spectrum analyser and set an EQ to remove it.

Hi Xavier, it's really as simple as what you can see on the picture attached. One master keyboard feeding PreenFM2 and Ambika, few pedals (delay and vibrato) and a Roland JD-Xi which is not on the picture, used only as a vocoder.

I'm combining both synths sounds most of the time it's quite lovely.

I don't see the picture you talk about.
Looking at the HTML source of you first post, i just saw you posted a JPG from dropbox.
But i assume it's not public and only visible to you when your dropbox session is open.

Hey Clément,

Nice, thanks for sharing that  :)
But after "this was my setup" i expected a list or a picture or something. What was your setup exactly ?

Olympia is a great hall, congrats :)


PreenFM2 / Re: any way to select scala files via midi?
« on: November 11, 2018, 11:45:57 AM »

Yes, you have to update to firmware 2.09 for that.
Use midi CC 12 to disable/enable scala scale (0 disable, any value > 0 enable).
Midi CC13 : the value will select the scala scale on your usb and load it.


PreenFM2 / Re: Feature Request: option to change LED function
« on: November 11, 2018, 11:44:48 AM »

No it's not possible.
But i agree it's a good idea.


At the bottom of the release page :
You have a that contains several banks.
And a DX7_SYS_zip that contains many DX7 sys files that the preenfm2 can read.

And yes, they must be in /pfm2/DX7 folder on the key.

Have you try feeding the attack with a short modulator ?
Or use an eveloppe to pitch shift the first ms ?
That often gives punchier attacks.


PreenFM2 / Re: hang with fast program change
« on: October 30, 2018, 10:35:27 PM »

Thanks for the report.
I'll have to take a look at that.

Could you can give more information about why you're doing exactly.

Have you selected a bank ?
(see program change here

Does it work when you send slowly program change ?

Thanks for sharing  :)
So nice to see the preenfm in this situation...

Latest version 2.09 :
This version fixes several annoying bugs that occured while using the editor or while controlling the preenfm2 from an external midi controller.

Latest firmwares and the bootloader are available from Github release folder:


WOW... thanks a lot.  :D
This was a very annoying bug, i'm glad it's fixed.

I'll publish a new "official" firmware a bit later.

OK i found a reproducible CRASH  !!
There were no verification on the incoming midi value for the number of voices. It was directly set on the instrument. It should have been limited like it is when you turn the encoder.
So if you set algo with 6op, number of voices to 4 and pushed it to all instruments (Global midi or same midi channel) it crashed.

If you're not too tired of trying firmware can you try this one with your global midi enabled ?  :)

Good news  :)

Thanks for the feedback.
Sending to glabal midi fills all 4 instruments at the same time and seems to produce a problem.
Maybe the preenfm2 does not have time to process all midi information and miss some of them.
Or maybe it's a real bug, i'll try when i have time.

Thanks again, for the report and for testing.


I really cannot reproduce any freeze with the above firmware.
There were some confusion between NRPN and CC in the preenfm2 firmware < 2.08d.

Arpegiator direction and octave were using CC 98 and 99 which are used by NRPN....  ::)
This is what i fixed above.
And i could not reproduce any problem with this fix.
I can PUSH hundreds of time "Squeechy 8" to my preenfm2 from my MAC through USB without any visible problem (specialy weird char in the arpegiator menu).

But i just saw a bug when you send value geater than the expected max value for a parameter.
This is what i fixed in this 2.08e. (sorry for the 2.09 name above, i should have kept it for the bug free version).

If you can try, that would be great.
