Hi all
I am using LFOs to internally modulate envelope parameters which I am sending via CV to my modular. Is it possible to have this modulation affect the envelopes in a fluid motion whilst the are in operation, instead of a set value being initiated as the envelope is triggered, like a sample and hold circuit?
Many thanks in advance.
im not certain but the envelopes might be calculated at note on
Damn. If thats true, that is a shame. I was hoping to be able to take care of this in the box / FH2, not a load of additional envelope modules. Thanks for replying.
dont take my word for it. i could be totally wrong
that kind of stuff should be done in the synth imo. serum2 does that all day long in any way you wish at audio rate if you want.
A possible suggestion, though bare in mind I don’t have a Hapax nor have I tried using FH-2’s envelopes:
Rather than buy more eurorack (?) EG modules or using Hapax’s envelopes you could try triggering FH-2’s envelopes from Hapax. I believe you can map CCs ( I guess these could possibly be generated by LFOs from Hapax) to control the envelope parameters on the FH-2. I’d imagine setting up the envelopes and the mapping on the FH-2 might be a bit of a ball ache but it might be worth trying it out to see if it might be an option for you.
Edit: I may well be wrong in my belief that CCs can be mapped to control envelope parameters on the FH-2. You may only be able to control the envelope depth from your Hapax. I think that you might be able to add some movement/shape to the envelopes using direct control (via CCs) or adding an LFO to the FH-2 output, though (parameters of which could be controlled by mapped CCs). It’s not the same thing as doing something like adjusting the decay length in realtime according to the amplitude of an LFO but it might be worth exploring. Of course you could add (sum) modulation from your modular, including stuff from FH-2 outputs, to the Hapax envelope (keeping the ability to affect it’s parameters per note by an internal LFO) once in the modular realm.
Thank you for the considered response. I was hoping the FH2 and Hapax would mean I could get rid of quite a few modules. It still might, just the modulateable envelopes is a big part of this plan. Super interesting idea about modulating the envelopes on the FH2. I will explore if feasible, as it certainly does not look achievable in the Hapax…. but this level of Expert Sleeping already fills me with a certain level of dread!
I checked the FH-2 manual and I was wrong. Its envelope parameters aren’t modulatable.
You can do a lot with CCs controlling direct output levels. You could make envelope type shapes with CC messages on the Hapax, I’d imagine. It might be a bit programmy and time consuming. But you could make a few shapes, copy and paste them, edit a few here and there, etc.
Controlling direct output levels with CCs is great for controlling VCAs. Allowing you to fade in/out modulation sources, e.g. cross-fading between envelopes and LFOs.
The LFOs on the FH-2 might be worth taking a look at too. The rate and level of those are modulatable by CCs. Not sure what else. You can combine classic waveform shapes, adjust their phase, etc. If the output range is set to 0V to 5V or 0V to 10V you’ll essentially get half wave rectified versions of the waveform.
A combination of direct level and LFO, maybe with a little ‘smoothing’ (slew) might be a pretty good modulation source to use in the modular.
I think with a bit of craft and patience you could get some nice envelope-like shapes from the Hapax and FH-2. Those and the modular should be a powerful combination.
Hoofjaw. Thanks again. Very interesting ideas. I shall report back when I get my teeth into the FH2 / Hapax link up.
