PreenFM2 / Re: USB is only good for power supply

Doh!

I thought it was only used to flash the bootloader....

I have many of this DIY mini USB connectors, PM me if you need one.

I built it and flashed its bootloader to v1.11 a few months ago with the mini-usb.

I just realized you wrote "Mini-USB" ?
So you have a CERB40 cpu board ?

You need a wire to link the case USB to the CERB40 mini USB.
Search for CERB40 in this old-PCB page :

PreenFM2 / Re: possibility of obtaining a new pcb? or schematic?
« on: April 12, 2017, 11:07:28 AM »
actually it was xavier (as usual) that posted the right schematic. i was just doing stupid copying of a GitHub link. :-)

You made me realize i still haven't put the real PCB on github  ;)

Hi,

Is the USB midi enabled ?
See 3.1 here, first setting :

Lokki, this is the preenF405 schema, aka the MCU/CPU board  ;)

Kirkwood, I still have to put the PCB in the github repository.
In the meantime you can download it from the download page on the preenfm2 site.
Here is the PCB dirrect download link :
https://www.dropbox.com/s/7k68bagutq6ri52/PreenFM2_R5c_Kicad.tgz?dl=1
You'll need kicad (http://kicad-pcb.org/) to load the project.

I attached a png that may help you.
Jumpers should work.

I don't think you can have broken anything.

PreenFM2 / Re: User wave forme ??

No, the RAM is integrated in the CPU.

Interesting question   :)
The user waveforms are loaded from the USB drive to the RAM when booting.
The limit is the available RAM of the CPU so i'm afraid it cannot be discussed ;)
The waveform is not stored with the preset, if you use a user waveform and modify it, that will modify your how your presets sound.

PreenFM2 / Re: Tuning issues
« on: March 29, 2017, 10:05:03 PM »

Not sure what it is.
Can be the preset that modify the tune over time.. When play one by one it's detuned, when played together it's tune.
Can you share your preset ?
Easiest way is to savethe default combo : Menu>save>deflt>Save.
 
Then plug the USB to your computer. Swith the preenfm2 on while pressing ENG. Press ENG again to access the stick from you computer.
The USB stick should be visible from your windows/mac/Linux machine.
And share here your /pfm2/DFLTCMBO.pfm.
That's the combo loaded when you boot.

Thanks
Thn

PreenFM2 / Re: distortion
« on: March 29, 2017, 04:25:03 PM »
A pure sin played alone can be noisy at low volume.

Set voice to 1 in Instrument 1, chose algo 1, and Mix1 to 1.00
Set it to 0 for instrument you don't use. I2, I3, I4.
And set Velo to 0. So that the wave is always at max volume.
If the sin is now OK then you have a normal behaviour.

All is digital and done on 18bits....
So the more voice you add the lower definition you'll have per voice or per carrier operator.
What you hear is the limit of the DAC.
But if you optimize by reducing the voices to the number of voices you really use, it should be fine.

PreenFM2 / Re: New firmware 2.07 (December 16th 2016)

Thanks. It's fixed now.
Dropbox recently changed the way we have to share files, which created lots of dead links...

PreenFM2 / Re: PC/Mac Editor version 2.00
« on: March 29, 2017, 04:12:49 PM »
so, what is the build procedure for linux ?

Get the source :
https://github.com/Ixox/preenfm2Controller

In Host/Builds/Linux
run 'make'
The app should be compiled in Host/Builds/Linux/build/

PreenFM2 / Re: Saving preset into empty Bank/Combo slot
« on: March 29, 2017, 04:10:17 PM »
Hi,

<Empty> means there's no bank.
Select an existing one to store your combo or presets.

You can create a bank from the menu : Tools>crea.
Or copy an existing bank on the USb stick directly from your computer and change the file name of the bank.

PreenFM2 / Re: Screen issue help!
« on: March 27, 2017, 10:46:50 AM »
Hi, sorry for the delay.
I don't think the issue can be because of the overclocking.
Did you buy your kit (prebuild unit ?)  from Van Daal Electronics ? I think they know this problem, try to contact them.
If not, what display do you have ?

PreenFM2 / Re: Voicing problem / feature?
« on: March 27, 2017, 10:45:03 AM »
The algo is the following, in order or priority :

1 . If a voice use the same midi note, the engine uses this voice and retriggers the sound...
2 . If there is a free voice (playing no note) use it.

After this all voices are playing note :
3 . If there is one or more voice that are in "release mode" (midi note off has been receive but the note is still playing), use the older one.
4 . If all voices are currently playing active note, any new midi note on will replace the older one.
