PreenFM2 / Re: global tune, midi-offset for presets and more...
« Last post by Xavier on August 14, 2017, 03:37:29 PM »
.... would need some ideas as to where the midi to frequency is happening in the code, global-tune would just be a constant fractional value added to the midi note.

Here is the newNote function where the frequency array is used.
https://github.com/Ixox/preenfm2/blob/master/src/synth/Osc.cpp#L180
(+ glideToNote function just bellow).

In the Osc.cpp init function, it should be easy to modify frequencies. Multiply all 128 values by 442/440 and you'll get a 442 hertz reference.

The array is one of the pre-generated array in :

for preset based midi offset the main question is where to put it in the menu...from there again it would only be an offset added to midinote...

it should go after the filter type in the engine menu i think. so i have to search for it in the code... :-)

i see now, that there is a possibility to adjust tuning when you use a scala file.

still think that a global tune based on a=440 would be very useful.

PreenFM2 / global tune, midi-offset for presets and more...
« Last post by lokki on August 13, 2017, 11:08:14 PM »
some suggestions:

-it would be great to have a global tuning setting, something like 435 to 448 in the global menu that tunes the preenfm to a reference a. nowadays more and more music is 442.
-a preset based midi offset would be great, in the range of -24 to +24 halftones (-+ 2 octaves). this is a feature found on many hardware synths, and would be very handy.

-i added cc3 to the matrix source, easy enough. but i thought it could be nice to have a user_cc value that you can set in the global menu and that will then be available in the modmatrix. that way everybody can define an individual cc for modulation, again very handy. i tried to implement this, but failed :-(

i would attempt the first two, but would need some ideas as to where the midi to frequency is happening in the code, global-tune would just be a constant fractional value added to the midi note.

PreenFM2 / Re: USB noise - cheap solution!

Thank you, I didn't know that - my Preen was built for me.  I removed the jumper and the noise is fully eliminated.

Keep up the excellent work!

PreenFM2 / Envelope for amplitude ?
« Last post by Happyanimal on August 13, 2017, 06:15:05 AM »
I see 2 envelopes available as modulators. Are there other envelopes available solely for amplitude of carrier? If they exist how do I access them? Only ones I currently see are in mod matrix.

hi xavier,

i spent today a lot of time with the preenfm and the sounds i get out of it (for experimental music) are just mind-blowing! thanks for that very nice synth!!

PreenFM2 / Re: Screen problem

ok, i hope it stays that way.

maybe my assumption with the vibrations causing the glitch were not so wrong :-)
