preenfm2 and preenfm3 / Re: PFM3 New Beta firmware : Toltekradiation's features + others (0.994)

Hi,

I think it can be put in the External link section of the wiki, a 3rd party tools page would do.

That page may contains, among other, links like those :

If you want to edit your own envelope shapes, i just did a github repo with my puredata patch :

Thanks to you for incorporating the features !

Tested the envelope display refreshing when CC is received, there is some issues :

CC_ENV_ATK_ALL (CC 80) : seems to modulate only operator 1 attack
CC_ENV_REL_ALL (CC 81) : modulate the release level instead of time, only operate on operator 1

it seems that CC 81-87 modulate the release level as well. Is it expected ?

mm, there is something funny about the envelopes :
curves seems to saved correctly but when i reload a patch, the release is set to zero on all operators.

Hi Xavier,
best wishes for this year !

i tried the firmware :
thanks for the curve & lfo visualizisation, it's really useful, especially for the enveloppes.
I could not figure out how to do this myself ^^

unfortunatelly, i met some issues.

after a fresh boot of the synth:
 one the lfo page, i can browse the waveform, modify any value, see the result.
then, if i change the timbre slot ( by pressing (+) ), something go wrong, i cannot edit the lfo anymore..
 
About the enveloppes :
i can edit the curve value, but after some value changes, the display is not refreshed anymore.

preenfm2 and preenfm3 / lfo shapes

« on: November 17, 2022, 10:24:08 PM »

as i found my preenfm lack of drifting, i added 3 new shapes for the lfos, to make it more "analog"

Brownian : lowpass filtered noise, discrete values
Wandering : interpolated noise, continuous values
Flow : lowpass filtered & interpolated noise, continuous values

audio demo : http://sndup.net/m8vs
(only changing the lfo shape, first the 5 known shapes modulate a filter, then the 3 new ones)

preenfm2 and preenfm3 / Re: Envelope curve selection

« on: November 10, 2022, 10:14:43 PM »

ok, it seems i'm done with that feature : here is a firmware which can save and load patch with envelope curve selection (Works with mixer and patches)
It's not a game changer feature, but i like it for what it is , and i think it's quite versatile with the user's curves

@Xavier, here is another PR, containing 2 of the previous ones (bugfix + reverb send mod)
https://github.com/Ixox/preenfm3/pull/33

preenfm2 and preenfm3 / Re: midi cc not working on preenfm3?

« on: November 07, 2022, 07:15:56 PM »

Another possibility is to drop off completly midi CC for reverb params and let people manage various reverb configuration with mixer files instead.
Which seems to be a good enough solution as you can easily tweak all parameters on the preenfm.

@sisyphus, what do you think about this ?

« on: November 06, 2022, 06:30:56 PM »

ok, you're right, it would be quite cpu hungry to deal with it like that, so i added some slowndown in the CC handling mecanism :
It would now recalculate changes once in 100 blocks.
Reverb params should not be realtime handled by CC anyway, it may be usefull to change once when loading songs or scene changing.

new PR here https://github.com/Ixox/preenfm3/pull/32

Hello,
i think it's about reverb param, as written here :
https://github.com/Ixox/preenfm3/blob/master/firmware/Src/midi/MidiDecoder.h#L67

yes, the midi cc handling for those params is missing.
I can prepare a PR for this, if needed.

preenfm2 and preenfm3 / Re: Reverb dry/wet modification

« on: November 05, 2022, 03:54:42 PM »

yes, the bug fix is in the 2nd PR as well, 1st one was done some weeks ago, did not noticed it was in 2nd one..

anyway, it is a nasty bug because it make the pfm3 crash.
it happen if in a patch, a carrier is in OSC_FT_KEYHZ mode, has a frequency of 0, and the fine tune is set to negative.
So when you go in EDIT mode, in TftDisplay::oscilloNewLowerFrequency negative values ​​are calculated => crash.

preenfm2 and preenfm3 / Reverb dry/wet modification

« on: November 05, 2022, 11:02:00 AM »

Hello,

i'm not totaly satisfied with the way the dry/wet work, sometimes a classic send is just what is needed.

So i propose another way :
- between 0 and 0.5, the dry/wet behave like a send : ie there is no volume loss from the dry signal.
- from 0.5 to 1, the dry fade out, we can hear only reverb signal at 1.

compiled firmware attached if anyone want to test.

@Xavier, i did a PR for that if you want to have a look : it's a very minor code modification.
+ There is also another PR for fixing a nasty bug
