How did you wire the Case?
Do you have a shielding on the metal case or its floating?

See if you are delivering enough voltage to the unit. Voltage Overhead distortion.

See if you have a correct opamps used.
See if you have the same distortion with a 9V PSU.
It might be related to many different things, but theese will be a first easy check.

Hi Bryan,

Post the calibration issue here also.
Xavier can dig into it and give you a response.

About the save issue.
It might be a faulty USB stick or maybe i has come loose.
See if you can load a patch?

Hi, I'm new to this so I truly apologize if this has been covered. I searched the forum but didn't find a clear answer to this.

I bought my preenfm2 prebuilt, second hand. I absolutely love this thing! The build seems legit and everything functions as it should and firmware is up to date. There's the slight 15khz noise that others have mentioned. That I can live with for now, and soon I will attempt the mod to deal with that.

But I'm experiencing a noticeable fuzz on pure sine waves. Even with the gain turned down, running a single op sine wave, there is a little hairiness that is driving me nuts. It's not noticeable with other waveforms or on complex patches, but it's definitely there. I'll try to post an audio recording soon. Just wanted to see if anybody had any quick info on the matter.
PreenFM2 / Tuning issues
« Last post by observer on Today at 02:05:27 AM »
I am running into a strange problem where if I use a patch to build chords, any chord containing more than 6 notes becomes detuned as pitches are added.

I noticed this while using the microtonal feature to create some music in Just Intonation, but then realized that this happens even with scala tunings disabled. does this happen on your preenfm2?

try this: Hold a C, add one by one: D-E-F-G-A-C. Now continue holding the two C keys, but let go of notes between. They are out of tune, but if you release and then retrigger them, they are now in tune.

Here are some examples that I recorded in just intonation so that it's more noticeable.
PreenFM2 / Saving preset into empty Bank/Combo slot
« Last post by fourhexagons on Today at 01:47:12 AM »

I just received a pre-built PreenFM2 from Ardi at Van Daal (thanks). It's running firmware v2.06. I edited the preset that was presented at startup and now I want to save it to an empty bank.

This is what I'm doing:

Menu > Save > Bank > select empty bank slot > press MENU

...but nothing happens.

Menu > Save > Combo > select empty combo slot > press MENU

...still nothing.

What am I missing?

Heads up: the link to firmware 2.07 (in the first post) is broken.
