preenfm2 and preenfm3 / filtering USB +5V line

« Last post by matrix12x on November 22, 2023, 01:10:34 AM »

Has anyone modded their Preen FM3 to add something like:

https://andybrown.me.uk/2015/07/24/usb-filtering/

Its a ferrite and some caps.

My PFM3 gets kind of noisy on USB power. Which I can work around with the DC connector and removing the USB DC jumpers. But, its just so darn convenient to use USB to power sometimes.

@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.

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

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'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.

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

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

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)

preenfm2 and preenfm3 / Re: tuning

« Last post by Toltekradiation on November 05, 2023, 11:31:38 AM »

Hello,
as i understand your question, i would add that in the pfm3, there is a scala mapping option (scala page 2)
where one can select the kind of mapping : continuous to keyboard

it is explained in the pfm 2 manual :
https://ixox.fr/preenfm2/preenfm/menu-mode/

The last option Map is set to Keyboard by default. In this mode, it will always make a C starting each scale. This is relevant for scales with number of notes different from 12. The keyboard mode makes scales easier to play on… keyboard.
‘Continuous’ option will start each next scale right after the previous one is finished, which make it harder to play on keyboard, but can be usefull with other kind of midi controller.

Hi,

The micro tonality can only be achieved through Scala files.
You can write your own scale and import them into your preenfm3.
So the limits are the scala file limit:
https://www.huygens-fokker.org/scala/scl_format.html

You can still change the default frequency values here (128 values for midi note from 0 to 127) :
https://github.com/Ixox/preenfm3/blob/master/firmware/Src/synth/waves.c#L1
And recompile the firmware.
