right.  so, wouldnt you know it, its not working for me. pfm2 doesnt even show in available dfu devices.  what now?  i bought this pre assembled so i wouldnt need to go through this.  also the cmd file in the zip doesnt do anything.  how do i even know anything is happening on the pfm2with no lights or screen?

preenfm2 and preenfm3 / The preenfm bootloader and how to flash it

« on: November 04, 2020, 12:30:43 AM »

Xavier's note

Split from an other thread.
Try to use this thread if you have any questions realated to flashing the bootloader

Original message

ok i took thumb drive out again and put p2_boot_1.13.bin in the pfm2 folder, booted into flash mode, flashed and it now says it has bootloader 1.12 installed and still wont allow usb access to thumb drive.

i realize i flashed bootloader to os so i reflashed 2.20

cool!  it works now.  but i had to take the thumb drive out to access it as my win10 computer made the usb drive inserted sound when i tried to enable usb drive access over the preen’s usb port but it never showed up in explorer.

What pfm2 bootloader did you install.
I published a 1.12 version which does not work.
Sorry about that, but the "USB access" from the computer should work with 1.11 and 1.13.
1.13 bootloader is included with the latest 2.20 zip file.

im talking about the one i bought from ardi.  how do you update just the bootloader?

interesting solution for the pitchbend, i prob wouldnt have thought of that!

also, why can i not pitchbend a full octave?  it seems i am only able to bend up to 10 semi tones?  this makes it hard to map a pitchbend melody...

the r6 oled saver times out immediately no matter what its set to. 

loving this synth!  so easy to get usable stuff and to animate!

xavier,

would you consider a wavetable oscillator?  im wondering how close is this to allowing user waveshapes...  it would sure update the preen sound and could be used to make oldschool and new school fm based sounds.  basically it would open up massive horizons for the sound designer. 

ok failing that, what do you think of morphing oscillator shapes?  maybe even just a few standard crossfades like sine to square or sine to triangle or sine to saw or saw to square...  maybe square to octave square or saw to octave saw or sine to octave sine etc etc

sorry if this makes anyone uncomfortable.  im just trying to think of ways to make preenfm3 more unique among fm + midi + desktops, which it is already of course!

just change parameters willy nilly until it makes sense to you.

start with 2 operators and see what the carrier/modulator relationship is, how one effects the other.  then youll have a better idea what is going on in larger algorithms.

modulator basically makes the carrier’s pitch go up and down really fast, resulting in a waveform that has extra harmonics.  you influence the modulator’s effect on the carrier with a simple volume envelope.  every operator (oscillator) has a volume envelope.  also the waveform all operators produce can contain different harmonics to begin with, producing output with different character.  some waveforms sound good, some not so much, its all down to your preference.

theres a filter after the fm part that works the same way as any other subtractive synth, except there are many distortion types as well.  this is part of what makes preenfm2 so awesome.  also the fact that there are multiple lfos and a patchbay make preenfm an extremely versatile and expressive synth.
