Reaktor 6
Subtractive Experimental

DESCRIPTION

Version 1.2
-Added customizable Pitch Bend Range (2, 3, 12, 24, 48 or 96)
-Added Amp Env back in
-Added mod section where you can choose if Filter is affected by Modwheel (CC74), Filter Env or Both
-Added mod section where you can choose if VCA is affected by Aftertouch (Channel Pressure), Amp Env or Both.
-Minor cosmetic changes

Version 1.1
-Routed CC74 (Timbre/Y Axis) to control Filter Envelope Sustain Level. This way, Filter Cutoff can be both controlled by the envelope and the Y-Axis.


Modified version of the 2-Osc Synthesizer so that it has 8 voices, each in its own midi channel and compatible with MPE. Aftertouch is mapped to the volume/amp of each voice.

Made for Linnstrument.

this is very useful. Thank You. Looking forward to whatever else you are working on.

Hola Thala, sounds like a good option! But I do not think that Blocks is the way to go for MPE with Reaktor, especially since Blocks are too CPU Intensive. I believe Blocks suits itself to copying eurorack, where you "perform" with the rack itself (using sequencers, CV processors, Clocks, etc.). I think MPE requires a more traditional approach, since you will be "performing" with the controller iself (in this case a Linnstrument). I am actually working on doing a new synth ensemble for MPE that does incorporate some of the ideas of Blocks (such as Mod buttons/sliders) and so far it is promising, as it may playing with 8 voices as it is not so CPU intensive.

the matrix is up too. even if you have to modify a lot on my poly blocks ensemble... a lot base wiring is already done. and in addition you will get a user friendly system to change poly blocks quickly.

got the linn finally. but i don`t have much time atm to jump on the mpe reaktor train. but i have modified my 16x16 routing matrix to process poly events (upload will follow soon). please have a look at this project i have started a while ago. shouldnt this be a good starting base for mpe-poly-blocks: https://www.native-instruments.com/de/reaktor-community/reaktor-user-library/entry/show/9363/

Thanks Thala! I see this ensemble as proving grounds. When everything works correctly and no improvement is possible to the MPE implementation, I might go ahead and add MPE compatibility to other instruments. Perhaps I could make it a win-win-win by reviving old instruments that freeze in the newer version of Mac OS! PS: I have Windows

thanks a lot, gustavo. this is well thought and doesn`t shut out any user, while doubling the possiblities :) this is a win-win!

Just a Note. "Modwheel" = CC74

@Thala the new version should help prevent no sound due to lack of aftertouch.

Hola Thala, for me what has worked best is to have aftertouch control volume instead of velocity, so you can control your expression more like a bowed violin than a plucked guitar. I am planning a second version this week where you could set a custon PB range, custom CC for y-axis, for z-axis and adding a switchable envelope for the amp. all of those would be excluded in snapshots so you can configure it to your liking regardless of the sounds :D

once the linn will be delivered finally... but i was wondering in general to use aftertouch to multiply the volume. isn`t his usually a job of the velocity? i can already draw mpe-sequences in bitwig, and was wondering why nothing is coming out of this ensemble. isn`t aftertouch usually used for sound manipulations? or is the linn sending the velocities on the aftertouch channel? feels wierd

Hola Thala, That is correct. Aftertouch is multiplying the last stage (amp/volume) so that it is controlled directly via channel aftertouch. If you are using a linnstrument, you must set it to use channel pressure.

its the aftertouch value 0 multiplying the last stage before soundoutput who is silencing the audio out. if i disconnect it...

hey i have tried it in several ways: reaktor standalone via pc-keyboard and in mpe mode inside bitwig. reaktor is receiving midi but there is no audio coming out of the ensemble. any tips?

@Greg the y-axis in my Linnstrument is configured in CC1. Next week I will try to incorporate a button to switch the y-axis from CC1 to CC74 and vice versa. Osc-2 is a Reaktor Factory thing, and it didn't have many routings, so I only grabbed what was available for the Z and Y axis. It does hang some notes but I haven't figured out why. Also, do not forget to configure your Roli so that it send midi info ONLY on the 8 channels that you specify in the Note In parameters.

Wow, this thing has a great sound for pitchbending! I have a Seaboard so it doesn't seem like y travel (slide in rolispeak) drives anything which I would expect since its made for Linnstrument. But the overall sound is superb. And the release velocity doesn't seem to be mapped to anything, right? I didn't notice that not all the notes tigger and a lot of notes hang but then again its probably just a Roli thing. Excited to see MPE beginning to emerge in these :)
