PreenFM2 / Combo Change Using Max/MSP?
« Last post by pmj on April 20, 2018, 10:46:24 AM »
I'm trying to use Max/MSP to send a Combo change instruction to the PreenFM2 but I'm not sure how to set up the [ctrlout] object to send this info:

Bank select (CC#0) and Bank Select LSB (#32)
Bank select=1 => BankLSB=Combo number

This is the help screen for [ctrlout] if any MIDI literate folk can make sense of it?

Thanks for any help, appreciate this is really a Max/MSP question but figured it was a specific PreenFM2 set up.

PreenFM2 / Re: USB noise - cheap solution!
« Last post by mzero on April 20, 2018, 06:26:11 AM »
Just leaving a note for others that might be searching up this topic:

This approach also worked for me: Remove Jmp2, then use the PSU for power, and USB just for MIDI - removes all the noise I was hearing on the audio outs when I was using just USB alone for both power and MIDI.

My unit is a van daal built unit, but it wasn't too hard to open it up and remove the jumper.

# have you matched the midi channel to the one in preen?
# have you set the preen internal midi mode to usb?

Yes to both, Ch#1 and USB Midi set to IN/Out

Correction to my first post. I tried it with JMP 2 removed not USB JMP, that was not installed as per build instructions.

PreenFM2 / No Midi over USB [SOLVED]
« Last post by slo on April 19, 2018, 04:49:54 PM »
I had some Preen boards made (R5d) from the Git files (thank you) and built a couple of Preen's, both using F405's, all is working well except for no midi over USB. The item is switched on in Tools/Settings. I've tried on both with USB JMP connected and not connected. Regular midi works just fine, and I can upload to the USB stick, also running the latest firmware on both. Any ideas?

PreenFM2 / Re: Problem starting PreenFM2
« Last post by klangFM on April 17, 2018, 07:13:48 PM »
None of my four new Intensio Nano 4GB stick boot at start up.

Press ENG" at startup works and a screen display and reboot is possible, also flashing...

Choose "MTX: DFU" tells me "STM32F4 USB DFU" and I have to restart. What does it means?
One stick boots sometimes after several restarts!

When I change USB stick when running every USB stick boots immediately! Controller permanent looks for a stick. Is a none working USB stick to fast or to slow??


Older Nano 4GB stick works and "pfm2" folder is on stick.


Is there a specification for USB stick to work properly with an original preen controller?

PreenFM2 / Octatrack and Preen Combo Change
« Last post by joradsilver on April 12, 2018, 06:13:56 PM »
Hey y'all has any one had luck using the octatrack to remotely program change the preen to different preset banks/combos.

I've been trying to read up on the previous posts but cant seem to wrap my head around how the OT sends Msb/LSB and how preen receives it. I'm most concerned with combo changes but would love to know how to do all of the above.

If anyone's had any luck please can you walk me through how to make this happen? Scrolling through banks on stage isn't a great look...

I just cant seem to communicate this info

Bank select (CC#0) and Bank Select LSB (#32)
Bank select=0 =>  BankLSB=Preenfm bank number
Bank select=1 => BankLSB=Combo number
Bank select=2 => BankLSB=DX7 bank 0->127
Bank select=3 => BankLSB=DX7 bank 128->255

From OT to Preen.
