PreenFM2 / Re: Yellow OLED : high frequency solution
« Last post by Xavier on December 12, 2018, 08:35:14 AM »
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.

Hello to all!
I am a newbie here.
I bought an assembled blue preenfm2 and I can hear the high noise that you are talking about.
It seems that if I use earphones it disappear.
Now, my problem is very big: I can't solder and I have no one that can help me.
The noise is a big problem to use the preen in the studio.
And now I have to use it in Conservatory too for my studies.

Came to report that nothing happens when i send a nrpn with parameter 16383, my controller doesnt receive any dump. tried max/min values from 0 to 127 in all combinations. Or is that function for usb only?

Edit: works now, nrpn has to be sent in absolute 14 bit, i had to use custom output command to my Dump button

wasnt there a CC command to make pfm dump a sysex patch? with the yamahas, i used to dump the patch in midiox and save them in sysex and throw them in a folder. on ipad there are many tools, i used to use mididesigner and made myself custom templates for each synth, and you could make a button to send custom CC etc

''The preenfm2 will
flush all its parameters with NRPN midi messages if it recevies a NRPN with
ParamLSB = 127 and ParamMSB = 127. Can be used by editors to read the preenfm2 current preset.''

Hmm, i must try this myself, useful for my BCR2000 also

nice upgrade, no more crashes! (for the moment, at least  ;D)
but like lokki said, it'd be cool to have the option to save combos with different midi channels, that way you can change the combo and have all instruments on same midi ch. for stacked, combo 2 to have each instrument on it's own channel etc. this way would integrate better with a sequencer that sends program changes. and when you make a new combo, let's say, every instrument is set as default (like you have it in settings) but with the ability to change that fast, not having to go each time in settings (i made some percussion patches, would love to use it as a drum machine sometimes). also, to have the option to save the performance parameters in the combos, and maybe a revert option for the encoders, and i can sell my soul to the.. no, actually i can sell my tx81z and other stuff, this is one of those little things with huge potential. Cheers!
PreenFM1 (the blue one) / Re: Presets for PreenFm (128 patches bank included)

Hello there!

I recently got a second hand preenfm and i'm trying to upload these 128 patches. The only problem is that after the sysex file is sent the preen keeps showing "waiting sysex..." with a second line saying "Bank:0  ##-200". moving the encoders doesn't change anything, if i press menu again a message DONE appears but the patches are nowhere to be found.

Anybody can help?  :-[ i'm a total beginner in fm synthesis so having a few more presets would be great!

i'm running firmware 2.00

thank you  :-*

Bonjour, je déterre ce topic, le titre me convenant trés bien.
Je viens de monter un PreenFM2 (kit complet récent de chez VanDaal). Il semble bien fonctionner, entre autre j'ai parcouru les banques dispos sur la clé. Un truc un peu étrange, j'ai différent niveau de brillance de l'écran, au repos assez sombre, s'eclaire lors d'une note on midi ou quand on touche un paramètre. Pourquoi pas? Par contre, quand j'édite un patch avec les encodeurs, assez rapidement j'obtiens un écran noir. Le midi, le son, et l'edition en aveugle continuent à fonctionner. Je dois redemarer pour retrouver l'affichage. Problème logiciel ou matériel?
L'écran affiche la version 2.08d au démarrage, les binaires sur la clé sont en p2_208b (trouvés sur la clé livré, je n'ai donc pas mis les 208a téléchargés). Je n'ai pas mis la resistance 68 ohms "useless if oled".
PreenFM2 / Re: Sawtooth waveform
« Last post by samuelous on December 01, 2018, 10:22:40 AM »
You can also try loading your own user waves. I tried using sampled saw waves from analog gear and ended up hating it for FM purposes. I also tried a more “accurate” saw wave and the reuksts were too buzzy and filled with unwanted artifacts.

Would you mind sharing some of those sampled saw waves? Now a few weeks further I see how saw isn't the ideal shape for FM synthesis and I probably won't be using it a lot. But I am curious :)

Damn, I knew something was wrong.
I edited the original post.

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.
