preenfm2 and preenfm3 / Mixer select from midi

« on: June 06, 2023, 07:39:43 PM »

Hello Xavier,

lately I tried to recall Mixer files from midi,
but found it a bit tricky to do, because of the CC#0 & #32 to set before sending program change.

In my opinion, it would be much easier to use midi bank 127, and program change.
I don't think midi bank 127 is likely to be frequently reach anyway !

for now, I'm a bit lost in the code, i guess it should be done in MidiDecoder.cpp but i have a hard time figuring things out

i would be grateful for some help here

midi echo is very cool on the midibox seq for example,
though i'm not sure how to implement this on the preen... maybe a special arp mode ?

There is also the modulator envelope loop trick, to mimick delayed notes !

Today i found this video about the Fugue Machine on iOS :

imagine this on the preenfm3 sequencer

Hi Tobias,
thanks for the appreciation !
if you want to check the latest features, the p3_timefx_7.bin firmware some post above would do : latter work done is mainly code cleaning and optimisation, there is very few difference about sound, only slight changes on the diffuser fx .

Best regards
Patrice

I hopefully fixed the two issues
- fix for the aliasing in Ping & Diff fx : added extra filtering in those
- fix for the bad noise click when going to the Diff fx

Here is an attached fw file.

There is a pull request as well !

No problem, thanks for reporting.
i'll have a look at this issue next week.

Hi Xavier,
excellent addition !
it will be very useful to have both fx layer.

about the Diffuser click, i'm not sure what's happening, i need to do some tests,
but I'm currently on vacation so i can't do anything until next week.

I had a look at the PR : nothing to complain on my side.

can't wait to test that firmware !

Hello @superfake,
thank you for your detailled report, i previously did not use spectrum analysers, only my ears, which has now some hf loss i fear.
So here is a version with more lp + notch filtering around 12khz on those fx, i hope it will make it usable, though it remains some aliasing.
Please, let me know if that's ok for you.

While i was at it, i added an optimisation i found lately on all the pitch shifter fx, which save quite some precious cycles !

Hi superfake,

The delay fx could be done with a sample rate reduction trick, which is x4 factor, so yes, the 12khz noise is awaited..
I did put some lowpass to soften this, but it's far from perfect, let's say it's a feature and call it vintage delay ^^
Though i will try some notch filtering to minimize the noise.

about the delay length, there is not so much ram left... better keep it for other features.

yes, the menu option is unlocked, no need for CC access.

Hi,
after some bugfix & enhancements, here is a quite mature version of these fx.
I removed the karplus strong fx, it was not so useful as an effect. Instead, there is a diffuser, to blur transients or add a light reverb "touch" to the sound.
There was improvements in some fx : the pitch shiters were simplified to lower cpu usage, it allowed to add some Eq ing in these to retrieve the lost bass, same for Bode filter.

@Xavier : pull request done in github.

no, there is no one cycle mode for lfos, but its worth saying that you can do cool things with the matrix : the mtx1-4 destination let you modulate the level of anything in the matrix slot 1 to 4,
so a lfo can last a few cycles when modulated by an envelope for example.
The preenfm matrix is already quite powerful !
