Title: Paraphonic vs Polyphonic
Post by: kuzma_p on August 17, 2015, 10:15:28 AM

Regarding paraphonic matrix was it made so because of lack of resources? It could be a huge drawback for someone i guess. Everyone is used to per-voice modulations these days IMO. For example global pitch modulation sounds strange and cheap a bit compared to per-voice vibrato which gives you a proper rich tones usually. Yeah you can do vibrato through modulation applied to 1Hz OP but..
Even my tx81z has per-voice LFO i quess (i can be wrong here though)
Filter could be still paraphonic though.

It's interesting but it's note related to 1.07 firmware so i've split this post.

Preenfm1 & 2 have always been like this by design for resource reason.
Real polyphony would require a big refactor and reduce the number of available voices.

Yeah i suspected this when i was messing with LFOs some time ago. It became more evident after you introduced Note scaling feature.
I can live with this though. But obviously i would not mind having polyphonic matrix with reduced voice number since it will sound more organic for me.

In fact it was not a so big refactoring. 
I didn't expect to have a sounding result in one evening.
I don't know how stable it is, but it sounds... And i agree per voice LFO sounds better  :D
Real polyphonic firmware first try (http://ixox.fr/NotLattestOne)
. Targeting filter frequency in the matrix needs more work
. Don't know if this firmware can handle as many voices as the other one in worst case situation
. Destination matrix broken : gate, Att*, Rel*....

But with that i need a second "Note" matrix source.  ;)
One fore IM* : to limit high frequency alilasing
One for Pan* : to have a stero image over the keyboard. Low note on the left, hight more on the right.

Thanks  :)
I could not prevent from fixing the Modwheell, Pitchbend (and other midi problem) problem before going to work :

Polyponic LFO firmware 1.99b (https://www.dropbox.com/s/v9xfyga1ymu984p/pfm2_1.99b.zip?dl=0)

Didn't delved deep. But it sounds pretty organic now. Nice!
Did not faced with any problem yet.
