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

(firmware below)

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 ?

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.

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

Sorry for anyone who did a test to that firmware : it did not work properly (it worked only once after installing )
The previous post is now updated with a working version.

That's what happen when you post a firmware and then go away on vacation without much testing !

Some progress on that project :
i now have a version which load user envelopes files from sd card,
it does not allow saving ; it needs a lot of testing before that anyway !

joined are four curve files to be stored in pfm3/envcurve
(some of those have extra clickyness)
But if you want more, the puredata patch is here for generating new usr files.

Code is on that branch : https://github.com/pvig/preenfm3/tree/env-curve

Thanks for the appreciation !
This keep me going on : next step is to handle the user curves the same way oscillators shapes are : with user files.
Then a puredata patch to generate the files and we're good to go for experiment

preenfm2 and preenfm3 / Envelope curve selection

« on: October 23, 2022, 09:47:58 PM »

Hello fellow preenfm lovers,

after hearing in various places on the internet about virtues of envelope curve selection, as done in many vst and synth, i tried something for the preenfm 3 :

i added a new page for the Oper/Env menu entry. From there, one can select the curve style of any stages of the envelopes.
While i was at it, i added some custom envelope curves (screenshot attached), so selection options are Exp / Lin / Log / Usr1 / Usr2 / Usr3 / Usr4.

The curve change is usualy quite subtile, but there is some use cases:
Exp shape on short attack is a little bit punchier than linear.
Log shape on attack may be good for woodwind instruments. It may also be useful on release part, to add more sustain to the sound.
Some of the custom curves sounds quite noisy on short envelopes, which may be used for adding noise burst on the attack, for example.

Please, let me know if this sounds useful for you or not so, or if all of this is complete nonsense .

(latest firmware, modified, attached below)

preenfm2 and preenfm3 / Re: Setting up new SD card for PreenFM3

« on: October 16, 2022, 12:29:27 PM »

hi,
the documentation about setting up the sd card is here :
https://github.com/Ixox/preenfm3/wiki/SD-card

the sd card content should be like this one :
https://github.com/Ixox/preenfm3/releases/download/v0.105/pfm3_SD.zip

Then, in the SD card, you would just have to replace the firmware file p3_0_105.bin with the latest one, from https://github.com/Ixox/preenfm3/releases/

Hi,
this one may do the job :
https://www.amazon.co.uk/dp/B07KPF15B1/ref=pe_3044141_185740131_TE_item
That's the one i'm using on my pfm3.
Works fine, but i had to fix it first by soldering the sd card pins myself...
