Vosim & al.
« on: November 11, 2023, 02:02:21 PM »
Hi,
lately i tried to make some choir patch on the preemfm and quite failed at it ::)
i guess it's not that easy to be done with fm, i had to find something else...

Fortunately, there is great informations on the internet !
https://electro-music.com/nm_classic/015_workshops/Clavia/NordModularWorkshops&Threads/WerkMap/WorkShops/Hordijk1999-2000/VOSIM.html
https://scsynth.org/t/fake-resonance-aka-windowed-sync/2720

so i tried to add new algo with windowed sync oscillators  :)

here is some quick snippets done with it :
http://sndup.net/tmfx
http://sndup.net/v7wy

Code start here :
https://github.com/pvig/preenfm3/blob/75144a2b58bacd852ae444163dde0cbc9ffc3432/firmware/Src/synth/Voice.cpp#L3621

There is a color code on the preen screen for synced osc.

I chose simple algos : 3 & 4 osc, based on Algo2, Algo 6.

Suggestions and comments welcome about that !

(firmware attached, built on top of 1.02)

Those samples sound awesome!!
I cant wait to try out your firmware tonight.

Any chance you have some suggested starting points for the IM settings?

i'm still learning how to use it as well, it's a trial and error process at this stage.
i guess sidebands created by IM add new formant peaks but alone it's not enough to make a lively voice articulation, one need many matrix modulation.

For now i do simple pseudo voxy resonant thingy patch, it's fun !

Below is the patch bank i currently use, if you want to have a look.

perfect. thanks.

I'v played with the three new Algorithms a bunch. I like Algo 30th best so far. I've been able to make a bunch of crazy sounds, but none were vocal or choral like yet. I think I'm not modulating right/enough, so your patches will help me in that direction.

i should try different algo, yes algo30 is the most versatile, with its second modulator.

any idea is welcome to help finding new interesting topology  :)

@Toltekradiation These patches are exactly what I wanted to do. After reviewing the patches, I realized I didn't have nearly enough modulation going on. Thanks for the help. :-) I'm probably going to spend all weekend playing with these new algorithms.

Here is a new version, with another algo, which let the master sync osc to be modulated.

And i found a trick to get a much larger pitch range modulation for the slaved osc, pitch modulation from the matrix is now x 16 for those.
It helps to get the fake resonance like heard in the supercollider thread above :D
