preenfm2 and preenfm3 / Re: more matrix sources

i feel it a bit weird to do such job from a synth.
Don't you use a sequencer ? i think it should be sequencer's job.

nope, https://puredata.info/
just change the value on the [poly] object in the patch, from 4 to 16.

Maybe a simple puredata patch would be suitable for the job,
i did a quick one, which cycle input notes to midi channel 1 to 4, here is a screenshot :

mmh, it may not be as simple as it seems, i fear, but why not getting a midigal to do this, and then more !

hello Maki,

i'm not sure how to do it on the pfm2 but some inspiration can be taken from the MI midipal
https://github.com/pichenettes/midipal/blob/master/midipal/apps/dispatcher.cc

The midipal manual :
https://pichenettes.github.io/mutable-instruments-diy-archive/midipal/manual/#dispatcher-dispatch

inp   5

Input channel.

Quote
mod cyc

Dispatching method
  • cyclic (cyc). Each new note is cyclically played on the next channel.
  • polyphonic (pol). The mapping of notes to channel uses a true voice stealing algorithm. The MIDIpal tries to reuse the same channel for occurrences of the same note ; or the least recently used channel.
  • random (rnd). Each new note is routed to a random channel.
  • stacking (stk). Each note is sent to all channels at the same time. Perfect for thickening a lead by sending it to several synths, or to several parts of the same multitimbral device.
  • velocity (vel). The louder (higher velocity) the note, the higher the MIDI channel it is sent to.
Quote
num   3

Number of output channels. For example, if out = 4 and num = 3, the notes will be dispatched to channels 4, 5 and 6.

Another version :
Algo29 is reworked as it was too close to algo31 : it's now a 4 osc, with two carrier, a classic one and a synced one.
Matrix modulation is now squared for synced oscillators : sounds more natural and possibly more extreme !

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

oh yes, i read your post a bit in hurry :-X

yes it's worth testing : just a few components :D

Hi,

i used ferrite on some diy modular, i think it's good to lower EMI noise a bit, but i don't think it would be enough to clean usb power, which can be very noisy..

There is also this kind of solution for this :
https://www.audiophonics.fr/en/interface-modules/usb-20-isolator-12mbps-1x-usb-a-to-4x-usb-a-module-p-17895.html

i tried cheap chinese usb isolator, it was real junk,
the audiophonics may work, i have not tested it but it's a reliable website in my opinion.
There is other usb isolators around, but not cheap...

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  :)

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.

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)

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/

Quote
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.

no i have no more step than save the default mixer, then power cycle.

I tried to start from Mixer/Default/Clear but no luck, after power cycle, Fx1 in Timbre1 is always Alkx.

i will try to dive a little bit more with the debugger to understand what's happening..

Hello Xavier,

great news !

i added a new commit on the initial PR, to tame the clicks on fx change, transition is now cleaner :
(https://github.com/Ixox/preenfm3/pull/43/commits/2be747d9122ad221bdbbf913b8194e82f7fdb50f)

to resume the PR, i would list as this  :

Two new granular fx : gra1 (Size, Spread) & gra2 (Pitch, Spread), those go in loop mode when Spread param = 1
Flange, Chorus, Dim rework : now have their own lfo
Dim rework : param2 is now mid/side param, 0 = mono, 0.5 = regular stereo, 1 = expanded stereo
Chorus rework : param2 control the amount for a second faster lfo ("Vibr" for vibrato)
Envelope display bug fix : no init on mixer load
FILTER_CRUSHER bug fix : no init on fx change

 
I found a bug that i could not fix for now : Fx1 has wrong type in timbre1 on default mixer load, only on synth start, not in manual load.
