thank you Xavier,
i could merge my code with the latest os version.
i also added the speed and duration matrix source.
Let me know if i can enhance something

@matrix12x, it is my last filter version, the latest code version from Xavier is not released yet in github.

hi @maki,
big thanks to you for suggesting this idea,
the Tyros is amazing !
and yes, the the Mind Control user manual is very useful ,  i will try soon to add the speed and duration source

hi @Xavier,
about the random value, i often use one or two lfo to get a random value on key press, to add some "analog" feel to a patch, but with this in the matrix sources, it free the lfo for a better use.
Other sources are fun to use on short notes loops, like 8 step : apply on a filter ,modulation or something unusual : that's usefull to lively up a sequence.
rpt is interesting, i think, when applied to osc pitch on a piano patch ; it open dangerous landscape : you must avoid too much note repeat, otherwise you will be out of tune..unless that's what you're looking for
i've not found yet an obvious use for actv, i have to play more with it.

preenfm2 and preenfm3 / more matrix sources

« on: January 06, 2020, 08:38:42 PM »

hi,
as suggested by @maki, i tried to add some sources in the matrix :

rndK (random on new Key) :
 new random value with each new note

notD (note Difference) :
 difference between current note value and previous one.

velD (velocity Difference) :
 difference between current velocity and previous one.

actv (actives voices) :
% of voices played in current timbre

rpt (repeat) :
at each new note, value increased by by 1/16 if note = previous note, else decrease (min 0, max 1).

dvrg (divergence) :
 value increased by by 1/16 if note different from previous note, else decrease.

that's what i could get with very few code modification and cpu impact.

here is the git commit for those interested :
https://github.com/pvig/preenfm2/commit/fa29cf8748360fbe0865c30cb072e355fef81082

and then the built file if you want to check it out.

hello @maki,
unfortunatelly, i have not much energy to continue, my day job take most of my time for now, maybe later.
Anyway you have very nice ideas to be tested ; very expressive possibilities

hi Xavier,
don't worry about the recent commit : i tried to make allpass filter frequency velocity dependant, was not useful, it was a regression ; last commit just put it back to a previous state.


BP2 : yes it doesn't work very well, it was a attempt to double sampling the original algo.

Peak: ok, i modified the reso curve response. there a small click when reso = 1, could not get rid of yet...

Notch: the resonance has expected behaviour, but, yes , this algo don't go very very high

BpDs : self oscillation is not expected, i modified this in my last commit

Pann : this one is a mixture of panning and 3x lowpass with different frequency spread around f

Sat : yes, it is a very simple digital distortion, sounds as expected.

LpSn : pos is an offset for a transfer function, add distortion, depending on pos and number of voices played. i let param1 control it to allow variable distortion. try it on a pure sin poly patch to use it a its best.

Not4 : quad notch filters, use it with a slow lfo for phasing effect

18db : ok, fixed this in last commit

La+d: ok, yes the ladder filter department is quite crowded, why not removing Lad+, Diod and L+d+

about the h3o+ (tb like) : i reworked the dynamics and accent circuit in one of my last commit if you want to check it out.

@observer , please check in menu Tools > Set > Receives = CC & NRPN
that may be the cause your issue.

ok, the accents may be useful after all
i got it back in my last commit, with small tweaks.
that 303 thing is quite difficult to get it right..

hi @Xavier,
many thanks for integrating some filters !

about the Xor, Txr1, Txr2, LPx1, LPx2 filters :
yes i also think that Xor, Txr1, Txr2, LPx2 may not be so interesting, those may be all be replaced with only LPx1.
it's my favorite one from this ensemble ; it allow progressive signal destruction and/or digital glitchy texture.

thank you for pointing me the velocity problem, i removed the accent thing as it can be done with other ways.
i did too much code lately and not sleeping enough

@observer : the filter CC should work, i checked this today without any problem.

@matrix12x : please check this one, there is 3 version of the formant filter
Oryx : 2 peaks formant filter with some distortion
Orx2 : 3 peaks formant filter
Orx3 : 3 peaks formant filter + more distortion (mono)

+ a bunch of ladder filters
18db : 3 pole soft LP
La+d: ladder version 1
Lad+: ladder version 2
Diod: ladder version 3
L+d+: ladder version 4

hi guys,
thanks for the support
@matrix12x : ok i will give it a try, but i fear it has to be a mono filter because the formant filter is quite cpu intensive.
however, i will try to find a lighter algo.

@baxgas i'm glad you like 
but it's still in progress ! i had lot of experiments with allpass filters lately, those are useful to had a little spectral blur in the sound.. it's subtile but the sound quality is a little bit enhanced with it.
So i put some allpass filters here and there as these are not cpu intensive..
And then the 3 previous Not3, Ap3, Ap3b are now Not4, Ap4 and Ap4b (1 more pole!)
+ 2 new filters :
Ap4D : another allpass quad flavour
Oryx : 3 bandpass formant filter, quite fun to play with

Sigm distortion has been reworked : it use now a more efficient formula and the sound is a little bit more dynamic.
