preenfm2 and preenfm3 / Re: FM3 MIDI CC list?

hi,
here is the CC list, from the code itself :

« on: October 23, 2021, 01:06:51 PM »

hello,
i had a go at adding the filter param2 to the modulation matrix.
Done it for the pfm3 as it's much easier to develop for.
I did it for all filters but the BP, which need too much processing.
The cpu footprint should be ok for the others, so here is a .bin if you want to check it out.

For @Xavier, i did a PR in github, to make modifications easier to read :

Thank you Xavier for naming the release by my pseudo but i would like to emphasize that the reverb is the Jon Dattorro's one from the famous paper here :
https://ccrma.stanford.edu/~dattorro/EffectDesignPart1.pdf

i did not create much about it

ok, let's go, here is my .txt waveforms.
If you want more, I also joined a puredata patch to let you generate the 1024 list (need the cyclone~ & zexy externals).
it does waveforms based on 3 sine addition, i think it's the most useful kind of waveforms as it does nice waveshaper (aka the 0hz carrier trick).

Hello Xavier,
i think there is some bugs.

In the preset recall :
In my version, some values were smoothed on preset change ; that part of the code was called continuously to make it happen.
In your integration, you do call FxBus::paramChanged() once on preset change, so the smoothing code should be removed.
here is my commit about it :
https://github.com/pvig/preenfm3/commit/fa6be48fb8f49bd753005f473e1220ad24f88ff9

About the predelay time, lfo speed values,
i did some stupid code mistakes , so these value change does not work anymore.
here is the commit :
https://github.com/pvig/preenfm3/commit/1ebce476547bbc72352021a21a66d388d906fc7a

While i was at it, i changed the order of some parameters in the reverb pages, i think it does more sense :

Thanks for the support
you found the problem : i have some trouble with the cleaning of my project :
with the latest v0.107 build from github, everything work perfectly.
but with my local sources, even if i clean before building (Project>Clean in STM32CubeIde), i get the issue.

I work currently on a copy of your branch FXGlobalFX-PVig, which i only slightly modified.
Maybe I have a small drift in my project configuration, i will try to find out what's wrong.

Thanks !

hmm, this problem is really weird :
i took another SD card, deep formated it, then put the official SD content (pfm3_SD.zip) on it.
With this SD, i could save every kind of files without any problem, ... but not the config 
if i follow the action in debug mode, it crash on line 89 in ConfigurationFile.cpp

well, i can still edit the SETTINGS.TXT by hand, so it's not such a big deal

thanks for the ideas.
i tried but it did not solve the issue, even with deep formatting with the official SD formater.
I will try again tomorrow with a minimal SD card content.

yes i can save mixer, default mixer, presets without problem.
I did not have pfm3/settings.txt on the SD,
so i made an empty one to test : freeze on config save
after reading the SD card again, the settings.txt is gone
so i got a working setting.txt from a pfm2, put it to the SD, reboot, save the config again : freeze again, and the settings.txt disappeared..

yes, quite weird.

I did a pull request with some fix for the parameter value change.

while i'm at it, i found a bug on config save : it freeze the synth on save, i could not get much information on what happening : in debug mode, the error stack is :
Thread #1 [main] 1 [core: 0] (Suspended : Signal : SIGTRAP:Trace/breakpoint trap)   
   HardFault_Handler() at stm32h7xx_it.c:106 0x80351f6   
   <signal handler called>() at 0xffffffe9

The hide/show solution is a great idea but some troubles so far :
well, no luck, the reverb do not produce any sound on my pmf3, i could not spot the problem so far .

About the preset param, i think it may be confusing for users :
one may not understand that changing preset will change some, not all, parameters of page 2 & 3 (if in display all mode).

I would separate clearly the two modes : no preset choosing in user mode.

If you wish to go this way i can redefine the presets, with all parameters.

hello Xavier,
many thanks for the code integration
your additions are very useful !

But, yes, i agree that linking all reverb parameters to the mixer does make sense.

cheers !
