PreenFM2 / Riser FX patches
« on: October 12, 2017, 02:41:00 AM »
I made a couple of Riser FX type patches you can load using the PreenFM2 Editor. Note: use the mod wheel to make it "rise."
This is a great synth.

PreenFM2 / [Resolved] Stuck on splash screen
« on: October 14, 2016, 02:02:49 AM »
Hi,

My Preen FM2 was working ok on 2.02o and I went to update to 2.06o it now boots to the splash screen (not the black squares, but the one that says "PreenFM2 v2.06 o" and I can't get anything to happen after that.
Any ideas?

I am on Bootloader 1.11.

Thanks,
John

PreenFM2 / LFO rate quantization
« on: December 31, 2015, 01:46:02 PM »
I was wondering if it were possible to quantize the LFO rate based on which note you play?
For example for C1 you get a quarter note (MC/4) and for C2 you quantize the LFO rate at a 16th note(MC/16).

PreenFM2 / Formant Filter
« on: October 25, 2014, 03:03:42 PM »

I was wondering if anyone has tried implementing a formant filter yet, something akin to the one on musicdsp.org

I was going to hack my way through this later this month and was wondering if there is anything I should keep an eye out for?

PreenFM2 / operator feedback
« on: June 14, 2014, 02:21:21 PM »
I was just looking over the DX7 algorithms and noticed that some allowed an operator to have feedback. I was wondering how we could do this on the PreenFM2?

Assuming we had a FEEDBACK parameter, would it be something like:
oscState1.frequency =  freq1 * voiceIm1 + oscState1.mainFrequencyPlusMatrix;
         float car1 = currentTimbre->osc1.getNextSample(&oscState1) * FEEDBACKValue * currentTimbre->mix1 * div2TimesVelocity;

PreenFM2 / waveforms
« on: June 08, 2014, 03:04:32 AM »
Hi,
I am interested in possibly trying to program one or two more waveforms for the oscillators such as a formant or something. I have bee with the FM8 and really love the way an FM modulated formant sounds.

I was wondering how difficult this would be? I started looking at the code in waveforms.java. Also would there be enough room left for something like this?

Would a good starting point be the Shruthi-1 code in his oscillator.cc file?

Thanks,
John

PreenFM2 / changing patches
« on: March 18, 2014, 02:31:30 AM »
Hi,
I have only been using my PreenFM2 for about a week on and off, and really enjoy it. I have what amounts to a silly question: Using the control surface, how do I change patches, other than loading them off the USB stick?

i.e. is there a bank of 128 patches like on the Shruthi, or is it just load the patch you like off the USB stick?

PreenFM2 / [Fixed] OS not finding /pfm2 directory
« on: March 09, 2014, 05:47:46 AM »
Hi,
My PreenFM2 seems to be working fine, but if I go to upgrade via the usb drive, the PreenFM2 OS is not finding the /pfm2 directory on the thumb drive. any ideas?

1) I made sure I created the directory and put the newest os files on there.

2) I can access the USB drive while it is installed in the PreenFM 2 after booting and holding down a key, then selecting the correct menu options.
