Choruses and flanger are great once modulated with an lfo, but it obviously would be quicker that lfo was included already in the fx.

Hello,
@ElVicente, you were right, i finally went this way as it's much faster to use, and it suit better existing patches , which may already use their own lfos...
The Dim fx lost resonance for a Mid/Side parameter, as the aim of this fx was the Roland Dim D chorus anyway, not a flanger.
The Chor fx now has a Vibr parameter, which is a fast second lfo, to make it sound like the classic ensemble chorus of the 70's.

So, here is a firmware file if anyone want to check it out.

@Xavier, these mods are pushed to the current pull request as well.

if you're not very familiar with code, take your time, read a lot the code before doing anything, as one must understand the logic of the architecture before anything.

Main code is in this directory :
https://github.com/Ixox/preenfm3/tree/master/firmware/Src/synth

it contains nearly everything relative to dsp code : oscillators, envelopes, filters etc..

Things relative to display are mostly here :
https://github.com/Ixox/preenfm3/tree/master/firmware/Src/hardware

But if i understand your wish, the perf screen may be quite handy for you : it is linked to the 2 params of filter1 by default and 4 others knobs are assignable in the matrix.
And there is some room to add various screen in that performance section !
For example I can imagine a second perf page with global ADSR modification of the carriers, another one for modulators..

How to make code change on the preenfm 3 ?

1. git clone https://github.com/Ixox/preenfm3.git
2. get stm32cubeide 1.5.1, newer version may cause troubles
available here : https://www.st.com/en/development-tools/stm32cubeide.html
3. get a ST-Link V2, cheap version works well too
4. do some code
5. upload and debug from stm32cubeide
6. share worthy modifications

hi,
After looking at https://github.com/Ixox/preenfm3/wiki/Upgrade-firmware-(Flash-bootloader)
, it seems that documentation is not clear about SD card access mode

so, in bootloader mode, press button 3 to go in SD card Access mode
Then the preen should show up in the finder as an external drive.
The files to transfer are the .bin

Nice !
The first track has some 90's AFX vibes, i like it !
Second one is ready for some horror film action, scary sounds but nice sound design.

Sorry, i won't change the design now: i prefer fx embedded in patch,
the memory is also needed for all other time domain fx (pitch shift, etc..),

It is what it is, and one can always use external fx for particular needs

Hello Xavier,

i did another little fix, about refreshing display of the envelopes after mixer loading..

these two commit are in this PR :
https://github.com/Ixox/preenfm3/pull/44

i could reproduce the issue around the mixer loading : envelope curves were not reloaded properly.
I did a fix for this, you can test it with the attached fw.

Details of the modifications here :
https://github.com/pvig/preenfm3/commit/ddb5fac8d0b416bc3764925cc02b5dea884b4300

i'm not sure i made the best possible fix, maybe Xavier would find a better way...

i'm far from my synths right now but will have a look at this in a week or so.
thanks for reporting.

I second the comment about the PERCUSSION bank, you demonstrate that one can do good drums patch with the simplest algorithm !
There is good patch in others patch bank as well.

Thanks !

as seen in another thread https://ixox.fr/forum/index.php?topic=69989.0, i did add two granular thingy, which i hope you will like.

So here is a version with various improvements :
- fine tuning of the grain fx
- some rework of the flanger
- better bass handling for the chorus
- various cpu & ram optimisation..
- much more delay & pingpong decay on maximum feedback

I don't think so, as there was no PR for mods from p3_timefx_9.
i'm going to post the latest version in the paraphonic fx thread, so we can finalize those developments.

ah ok,
i think it's much easier to do such program in your regular pc : much cpu & ram available, many tools available.

yes, try puredata, it's free and very cool.
