How about an envelope generator, triggered with note on , creating cc’s etc.
I want to give this a bump. Some synths have 1 envelope only for VCA and VCF but VCF can be controlled via MIDI CC. A simple ADSR envelope pipe could enable those synths with independent envelopes for VCA, VCF or VCO. Even better: a complex envelope pipe with more than 4 steps per envelope. Just dreaming about having a 8-step envelope as the Casio CZ series for any synth that has the according MIDI CC controls available

@Synthfluencer This is intriguing!
How do you think it would work: a bit like an adapted limited-duration LFO?
If that’s the case, it would fit with the Midihub style to have a pipe for each “arc” of the envelope “polygon”(some linked to NoteOn, others NoteOff and each to the previous) which would give you as many steps as you like (within pipe max constraint).
But wouldn’t it also only work mono-phonically (I guess paraphonically)?
@resonotter I was thinking about one pipe, triggered by Note-On event. One parameter of the pipe could be target (CC value, VCA, Pitch, …) followed by a number of time (ms) and level (0-128) pair values. First pair represents attack, second (third, fourth…) decay, followed by sustain and last step is always release. But the idea of one pipe for each envelope stage sounds also interesting. It may cause problems since the ADSR cycle sould always be “complete” (at least ASR) in my opinion.
This sounds interesting; buildung a ADSR by combining a couple of LFO pipes in one shot mode with different waveforms (Saw-up + Saw-down)… I’m going to do some experiments with those 
IMHO this is determined by the target synth; how it processes incoming eg CC values.

Yeah, I guess.
my thinking was that if the synth has say CC#26 controlling VCF, then a new note would retrigger the Env pipes.
Whatever, I’d still like to play with “Envelope Pipes”; it would be like the KomplexModulator on the Iridium but not tied to fixed length steps and periodicity. I’d use that on way more stuff than amp & freq!

+1 for envelope generator pipe, on/off with a note value (trigger, one shot), possible to loop, (BPM sync), depth param to grow/shrink the whole envelope. If not ADSR, AD fine too.
Yeah, I’d have to +1 this as well
