EDIT : pages 5-11 were filled with tons of delirious nonsenses and personal threats from 2 vile haters (also subscribed on warez websites using the same pseudonym as in KVR) making this thread completely unreadable. Both haters are now definitely banned by KVR moderators and their posts have been deleted from the thread.
My big thank you to the KVRAudio moderators, with your bans you cleaned up this thread (and probably many others too) making it again a joinable place.
And many thanks to the real, fair users joining this discussion - it's a pleasure to have a talk in a such polite way.
A description of the 3 analogue envelopes will follow.

The Analogue Envelope Generators (Modulation EGs and Amplitude EG)
RawPrime features three (3) identical analogue envelope generators : two with freely-assignable destinations (via modulation matrix, described soon) and the last one hardwired to the VCA.
All the three 4-stages (ADSR) analogue envelope generators are modeled after the CEM3310 hardware - simulating its capacitors' charging/discharging responses and behaviour - with a very sharp attack time (0.3 ms). There's also a unified voice retrig system, affecting all the three EGs.

VOL [MIN...MAX] : Set the VCA overall volume.
RTG [OFF...ON] : Enable or disable the voice retrig. This also affects both EG1 and EG2.
EG-1 / EG-2 / EG-VCA ATTACK [0.3ms...10sec] : Set the EG-1 / EG-2 / EG-VCA envelope generator attack time.
EG-1 / EG-2 / EG-VCA DECAY [1ms...10sec] : Set the EG-1 / EG-2 / EG-VCA envelope generator decay time.
EG-1 / EG-2 / EG-VCA SUSTAIN [MIN...MAX] : Set the EG-1 / EG-2 / EG-VCA envelope generator sustain level.
EG-1 / EG-2 / EG-VCA RELEASE [1ms...10sec] : Set the EG-1 / EG-2 / EG-VCA envelope generator release time.

RawPrime will be available in about 48h.
After some comments here by users who said to expressly love "dirty" or "crunchy" sonorities (typical of the "aliasing" phenomenon), here's an audio demo of a preset named "Stellar Flux" (Mirror Freq Expansion Library) :

Jakub is a pure genius.
Learned a lot from him both for my Euro Rack setup and for vcv patches and experimentation.
If you want to learn some aliasing trick in synth this is pure gold.
You can also try make yourself aliasing synth with vcv rack 2 free version.
It’s always nice to be teached like this.

And now, the colorful RawPrime Modulation Matrix !

At its heart, RawPrime features a complete, color-driven modulation matrix section to easily access the synthesizer's modulation sources and destinations. All knobs / parameters values are bipolar.
For example by assigning a single or multiple modulation sources to the generator 1 morphing, a continuously evolving complex waveform will be output.
SOURCES [L1...L2...E1...E2...VL...MW] : The modulation sources are
LFO 1 amount (L1)
LFO 2 amount (L2)
ENV 1 amount (E1)
ENV 2 amount (E2)
note velocity amount (VL)
modulation wheel amount (MW)
DESTINATIONS [P1...P2...M1...M2...FC...R1...R2] : The modulation destinations are
oscillator 1 pitch (P1)
oscillator 2 pitch (P2)
oscillator 1 morph (M1)
oscillator 2 morph (M2)
low-pass filter cutoff (FC)
LFO 1 rate (R1)
LFO 2 rate (R2)
When modulation wheel (MW) buttons are active, the modulation amount for that specific destination is set by the modulation wheel control. Otherwise, the modulation amount is passed as it is (as defined in the matrix column).

RawPrime Polyphonic Arpeggiator

RawPrime features a creative, 4-mode performance arpeggiator. Instead of the usual UP, DOWN, etc. modes, this arpeggiator is based on an unconventional note-priority approach : it generates a note sequence depending on the order in wich notes have been depressed - so you can perform up, down, alt, etc. in real time depending on the notes you play.
ARP [OFF...F1...A1...F2...A2] : Enable the arpeggiator and set its operative mode.
DIV [1/16...1/8] : Arpeggiator clock divider.

Finally, RawPrime features two effect processors slots (on the top side, reminding microcomputers / consoles cartridges or "game packs") featuring the same devices / units as found in ZeroBox.

CHOR-S [BWIDTH,CENTER,FBACK,RATE]
FLANG-R [BWIDTH,CENTER,FBACK,RATE]
X-TREME [PRE,LOAD,POST]
SOLID-A [PRE,LOAD,POST]
PHEEBEE [PRE,THRSH,POST]
CRUSH-R [PRE,DEPTH,POST]
D-LAY [LEFT N/T,RIGHT N/T,FBACK,TONE,MIX]
REEVERB [SIZE,WIDTH,DAMP,MIX]
And that's a wrap, thank you for following my walkthrough - I hope you'll find RawPrime an interesting synthesis system.

Nice, Bruno !
And now it would be the perfect time to get the most overdue update for IronAxe on its way. Please stop doing new stuff for a while and port this gem into the current decade...

Maybe you want to update the content info for the expansion pack named Mirror Freqs from "Single Expansion for ResonHeart" to "...RawPrime" meanwhile in the XhunAudio shop ... ?!

Thank you kylie for the feedback !

Is the synth released?

It’s released. $49 on his site. We should have that price up soon, just waiting for his US distributor to add it.
