keytracking as mod source?. other suggestions
« on: November 09, 2020, 05:27:00 PM »
im surprised i dont see this in the list...  is it there?  id like to map it to the filter.

im starting to layer parts together to make a voice with more character than is possible with 1 part...  it would be nice to have a global effect/filter layer

the glide is still not as adjustable as i would like...  could it be made to go slower?

it might be nice to modulate other parameters like in the filter, or maybe the algorithm.

what do you think?

It's possible to use midi note to modulate any parameter.
See part "4.4 Note Midi Scaling"
http://ixox.fr/preenfm2/preenfm/synth-edit-mode/
But if you expect to use the exact frequency of the note and set the the Low pass frequency, it will require some adjustment.

Glide 11 and 12 have been added recently for slow glide. You need slower than that ?
You may think about using any LFO or env to the matrix target "o*Fq".
"o*Fq" ajust all operator frequency and make a global frequency shift.
If you manage to have  the firmware compiling, i can guide you so that you can add what you want.

Yes Filter param2 could be modulated . It was not for performance reason as some of the filter requires lots of calcul when you change this value.

Modulating the filter itself or the algo, can only produce audio clicks and bad sounds.
You can still modulate them with external midi CC though if you really want to give a try.

it would suit me fine if the polyphony shrank while the patch complexity goes up, as i often limit my parts to mono anyway.

im no coder.  are you saying code can be tweaked to make glide slower?  i will use the lfo to pitch.  and thank you for the amazing lfos!

im not clear what mod matrix source will allow me to modulate a destination with keytracking

"Not1" and "Not2" are the two sources linked to :

Sounds like the preenfm is laughing sometimes.
Specially when looking at your soundcloud avatar while listening  ;D

ok im not sure if you would want this but i think it would be nice to change the color of the noise source and maybe even dynamically for effects.  is there a way to do this?  maybe a clever use of an algorithm?

im definitely enjoying layering parts in order to add character to a sound.

how about less polyphony and more filter layers?   ;D

On a normal subtractive synth you change the color of the noise with a lp or bandpass filter...or do you really mean the color of the noise, like white, brown noise etc? I see little use in changing that dynamically...

dynamic change would be to obtain special fx similar to video game sounds.  a filter would definitely work but a constant color would be great within a larger patch where you cant apply a filter to only the noise.  sometimes its nice to have only sizzle instead of wide band noise because the rumble gets in the way of other elements in the voice.  also darker color noise can thicken up a sound without being super noticeable.

I agree that it would be nice to choose different kind of noises, but maybe not dynamically but static per preset....

noise could be made to change color depending on the operator frequency and then it would be dynamic too

FM can do that.
Example ALGO1.
. Set Op>Op1 with SIN/Keyb/1.0/0.0.
. Set Op>Op2 with Rand(noise)
. Set FM>FM>MI With a high value > 10 for IM2->1.
Then you have a noise that follows your midi note.

If you set a fixed frequency for Op1, noise can be fixed event if some other operators follow the keyboard note frequency.

this will produce different colors of noise?
