PreenFM2 / Re: Problem starting PreenFM2
« on: June 18, 2018, 11:10:49 AM »
Now I don't know what I'm talking about obviously, but: Would it make sense to have the screen say "Reading USB..." instead of just blocks at that point, so that it is obvious that the problem is USB related?

When i wrote this part of code i didn't expect the USB reading to fail with some USB stick.
But that's a good point ;)

....I cannot boot normally, I just get the full blocks in the OLED. I have a self-made preen405....

The full blocks in the display are displayed by the firmwre.
It freeze here if the firmware cannot access the USB drive.
2 possiblities : you didn't t have the expected "/pfm2/" folder or your USB stick is not readable by the preenfm2.


PreenFM2 / Re: Octatrack and Preen Combo Change
« on: June 04, 2018, 11:36:07 AM »


I think it's not very clear from the doc.
You first select the bank once.
Then, use program changes to trigger a preset load from the selected bank.

Chosing the bank is done through regular CC.
If you want the first bank of combo :
Send 1 to CC#0 (Combo)
Send 0 to CC#32 (Combo bank number).

Then sending program change will load combo from the first bank of your combo bank.

But i  have no idea how to send that from the octatrack.
And i still haven't looked at what Lokki did exactly for program change, so i cannot comment  ;)

Interesting, thanks for the feedback.

PreenFM2 / Re: Video: FM and FM2 original release dates?
« on: June 03, 2018, 06:35:10 PM »

interesting question.  ;)

I had to make some research.
This is the first thread (in french) that talks about the prrenfm(1).,preenfm-diy-synthe-fm.html
First kits of this first version were available in december 2011.

2 years later in november 2013, i released the preenfm2 (which uses a much more powerfull CPU) with a beta version of the firmware.

Waiting for your video :)


PreenFM2 / Re: Any way to get LFOs and ADSRs out of the preenfm2?

Analog outputs are not wired to the PCB. So it's not possible in the current state to output any signal other than the audio.

.bnk are roughly memory dump of the parameters. So they're not editable with a text editor.
Load your preset in the preenfm2, start the PC/mac editor, press "pull" and edit.
Once edited save them on the preenfm2.

Is there a quick way to delete a voice within a bank? 

Delete a preset from a bank ? No.

Or do you have to overwrite it with another to get rid of something you don't want to store any more?

Yes overwrite it sounds like a good way to delete it.  ;)

PreenFM2 / Re: Latest firmware : 2.08b (2018 April 1st)
« on: April 02, 2018, 09:34:20 PM »

Oops... right.
I created the release before pushing my modification.
The binary was correct though.

Anyway, i created a 2.08b2 tag for the release.

Thanks :)

2.08b fixes a bug that could be annoying.

Hey stelpa,

Isn't FTune what you're looking at ?
Or maybe being able to change with more precision Freq ? so that you can chose something like 0.99 ?

Mod Matrix using midi note number is actually a good way to do that   :)

Thanks for the report.
I had a look and saw a problem.
I don't have access to my preenfm at the moment. As you can compile the code, can you try the following :

See here in :
We assign a new voice and return.
without setting this->lastPlayedNote  which is done only line 363.

Can you try to add
Code: [Select]
this->lastPlayedNote  = n;line 295 ?
And recompile ?
