Or you could base the functionality around a hierarchy of the impacts of parameters.  If I wanted something to sound "brighter", that could mean adjusting a group of parameters. Or maybe a bit more "dirt", that could mean a different set of parameters, that would be adjusted together.  then, if I want to dive in to see what "dirty" actually means, I could open up a window that shows the individual parameters that add "dirt" to a sound.

It's a bit like the drill-down functionality in a data warehouse reporting tool.  At the dashboard level, I see some graphs, but double-click on a portion of the graph and I see the detailed data behind it.

Lots of interesting suggestions and parameter tweak ideas .
Could think about it for the next VST.

But don't expect this in PreenFM mk2...  ;-)
It will be an upgraded version of the original one but not that different.

"It will be an upgraded version of the original one but not that different."

Xavier, that's good news and bad news I suppose.  It's good because it means my current PreenFM will not be completely out-of-date, but bad because it means I might not need the new version.

Yes, you'll be able to save money if you don't need stereo, multitimbral and more voices among other things...    ;)
Sound quality is also better/different (floating point engine + real DACs), but i think low fi people can like better the origial one.
The look, surface controle and parameters will be very similar.

Xavier, do you have any plans to do a PCB + processor option?

Thanks guys  :)

Randy, I don't not have any plan for that.

Have you seen that burning the firmware on the PreenFM2 do not require any special material ?
Once your PreenFM2 is plugged to a computer with a USB cable Type B (regular printer cable) you can flash it by linking JMP3 on the PCB.
On Windows you only have to install driver once. See http://ixox.fr/preenfm2/built-it/burn-firmware/

If you don't want to do that and are ready to pay 35 Euros for a pre burned cerb40, PM me. I have 2 or 3 spare pieces. ;-)

what's the function of the holes in the base of the case?

3.3V and 5V regulator are in the middle of this holes. Better dissipation + smaller enclosure.

I nearly finished my PreenFM 2. I'm still waiting on my Cerb40, but it should be here tomorrow :)

What's with the three headers P1-3? :) In the pcb files I read something about Shruthi-1 Filter o0

Great  :D
Please post a pitcure, that will be the first PreenFM2 built outside my house.

Was the BOM and build pages OK ?

About the headers :
P1 : pins for a st link V2 to easily flash and debug the firmware

P2 : anything + contains an input 5V. So theorically a Shruthi SMR4 filter could be plugged here controlled from the PreenFM. That's the idea, i've never tried neither writed a single line of code for this.
P3 : Ouput 3.3V + 4 pins that can read analog input. Never tried anything with that too.

Oh do tell.  FM Synth+analog filter = winning.  Take a listen to TK's Midibox FM which has CEM VCFs added: http://midibox.org/forums/topic/6092-pimp-my-behringer/#entry40383

I will send you a built and tested SMR filterboard if you make this happen..

Thanks i already have a SMR filter board ;-)
Unfortunately, it's very low in my priority list...
