PreenFM2 / Re: New filters
« on: January 06, 2020, 10:20:14 PM »

. I hesitate for SAT.

@Xavier – I find Sat very nice on pure Sine-waves, can make nice Waveshaping.

Didn't have time recently to try out the other algos, but you are right about Txr1, Txr2 didn't find those very useful.
The different pole HP, LP, BP filters have subtle differences, that's true, maybe only the max. Res setting
LPx variations are also a bit so-so, but they can be useful to have multiple filters if possible.

Altogether it is definitely good to have the filters implemented in the official firmware, Toltekradiation did a wonderful work!

Wow, thanks! I finally uploaded the new effects, and they sound great!
Big thanks for keeping the order of the previous effects (adding new ones to the end of the list), so that older patches don't mess up the FX settings.

@Toltekradiation Thanks!
Didn't use much the LPx1-2 filters so far, so can't tell, but Fold adjustable parameter seems nice addition instead of the Mix

@Toltekradiation, thanks, I flashed the new OS, and it seems working nicely (no lags). I didn't test every FX thoroughly so can't really tell the difference for now, but if it improved – so better :)

Now what I would find an improvement, if we have so sophisticated FX section, is to have a bit more interaction with the Envelopes in the Matrix (eg. I always use Env1 for interaction with the Filter Freq on Note-Events), but maybe it is more a task for Xavier?
I think it would be nice to have modulation destination to control Env1 speed, globally or by parameters (Attack, Decay, Release). This way the Not1 could be used for controlling Env1 speed – good for Keyboard tracking of Env1.
Also would be nice to make available the Filter Parameter2 (eg. Resonance) in the Mod-Matrix. It is available on CC#72 btw.

@Toltekradiation definitely dive in to sound design, you deserve a bit fun also after the hard work on engineering ;-)
I hope these improvements will also get in to the "official" OS. @Xavier?

@Toltekradiation Thank you for the improvements, now it works really smoothly at my PreenFM2, fantastic  :)
I will test it thoroughly and let you know if I find some more tips for improvement, but for now it seems really-really great!
One thing I noticed with the file-naming is that the OS Flasher recognises the .bin only if it's filename is starting with p2_ Otherwise it is great you renamed them, so the filename truncation is much more informative!

Just a question, will the position of the effects move in some future version (planning adding some more), so I can track which parameters were saved with the patches? Now the old patches load in with a bit different FX, I guess because it saves the ID, and it changes if some new are added before.

Thank you so much for the great job you done with these improvements!

@Toltekradiation I understand there is a limitation in processing power... btw. you used the overclocked version (210o), but maybe the "regular" version is a bit less demanding? (just an idea)

@Toltekradiation Thanks, I'm really eagerly waiting to hear and test them! :-)

One thing I noted is that when I save the patches with the Filters, in the new version they are messed up, probably because of the numbered positions of the algorithms, and that they change eg. there are more filters before the Distortions?

Also, with the new OS, the parameter changes seem much more sluggish, eg. I have 4 Channels sequenced and I try to change a paramter and it increments only a few steps then stops, also the Inst change is much slower, with a blink of the LCD. Maybe these are already too much for the processor to handle? :-(

Can the filename of the bins be renamed so the PreenFm2 truncation of the characters is a bit more informative?

@Toltekradiation all the stuff is great, it really adds a lot to the richness of the FM synthesis
Haven't dug really much deep in all the uses (although my PreenFM2 is always on in my spare time, since you made these additions :-) ), but these are some experiences so far

- Txr1 and Txr2: seems just like adding some noise to the signal? Of course the filters will behave differently with different signals that are put through, so I believe the type of the source sound is also important.

- Can the Mix parameter (generally) be replaced to some filter changing function? (like eg. LPx1 that besides Frequency the other parameter changes the xor amount). I think these kind of effects are not like eg. Reverb/Delay or similar that dry/wet ratio is that important.

- Is it possible to implement algorithm for Notch type effects (inverse of Band-Pass, that it just removes the Frequency)

You are right about the mixing of the 4 instruments, it can really make a difference with the filtering. I also know that the PreenFM2 architecture is a bit limited in this regard, as it acts just at the end of the signal-chain as a per-channel filter/effect, although modulatable by the Modulation matrix. 
I wouldn't mind to have a lot of filters, why not :-) Just if some patches are saved with some effect, and they got replaced in the meantime, they will probably get back to the default, or switch to some other type.

As for the Chorus, and modulation effects, I know the trick of slight detuning, it is also very nice to detune a bit the modulator in comparison to the Operator, adds nice phasing effects that can turn to some waveshaping if modulated to more extremes. The FM is a great system for sound-mangling :-)

@Toltekradiation: Thanks for the infos!
Will check also the new Filters also. Btw. Are these flavours and different types just for testing and then at the end you'll leave the best one, or you plan to leave all of them?

The Filter improvements are really-really useful, thank you! I also found the original PreenFM2 Filter algorithms a bit weak...

A few thoughts:
- some infos about the implemented filters and the parameters they use (at parameters Cutof/Resonance) could be useful, so that it is easier to understand what is what (maybe at the git page
- any chance to implement some Flanger, Phaser, Chorus algorithms? Maybe even Delay and Reverb? Or even combination of Modulation/Delay effects (but I understand there could be some processing-power limitations)
- I don't know if it is possible, but could be very nice to modulate the Resonance (or any second) parameter also from the Modulation Destinations?

Keep up the good work!

(PS: hope these improvements will also get in the official version)

Wow, sounds Funtastick! Looking forward to try it out!

Thanks for improving this great little synth!

Yeah, sure I use it also like that, but performance-wise would be nicer to have more instruments/channels available on one keyboard setup...

My idea is to use it with Ableton Live in one track, and Live can send only on one MIDI channel per track.

Is it not possible to implement this feature because of the software limitations?


First of all, thanks for developing this great little powerful synth! I'm really happy the development is active :-)

I have suggestion to implement the feature of Note Range for the Instruments, which could make possible a lot of different nice applications through MIDI controllers.
eg. then we could make
Splits, like Instrument 1 – Bass, Instrument 2 – Lead, both set at MIDI Ch.1, with Note Ranges Inst.1: C0-B2, Inst.2: C3-C7
Drum Kits, like Inst.1: Kick, Inst.2: Snare, Inst.3: High hat, Inst.4: Toms, all set to the same MIDI channel, with different note ranges
And many more options (eg. layers)...

Best Regards,
