Even after updating to the last firmware, I get pops when using the envelope. I’m trying to use it as a basic envelope controlling a VCA to stop an oscillator from droning. What I do:
I set two layers on track 1: Note + Mod, then I add the Env on this track.
I send CV from track 1 to the V/Oct of the OSC
I send CV from track 2 (mod) to the CV input of my mixer/VCA (Nano StMar)
It does the job, but the pops make it unusable. The settings on the ENV are:
Attack: 40
Decay: 0
Sustain: 100
Release: 20
The rest of the settings are set by default.
I’m curios if anyone else has this problem too. When I use the same setup, but with Instruo Ceis as an ENV instead of the Hermod+, everything works perfectly.
I believe that’s due to a limitation of the envelope, which is that it restarts ‘abruptly’. One countermeasure could be to set a very subtle GLIDE effect, to smooth the transitions, or run the envelope CV through a slew limiter.
I’ll look into adding this subtle smoothing within the ENV effect.
Thanks for the suggestions. I don’t have a slew limiter, but I added Glide from the Hermod+ and it didn’t solve the problem unfortunately. I tried adding it both on the first, as well as on the second track (not at the same time). Please try it yourself, maybe I didn’t do it right. Thanks a lot!
I have the same problem with the envelope in the Hermod+. No other envelope I have exhibit a similar behavior or problem even when they are reset abruptly. With a short attack some of the more snappy envelopes can have an attack transient - a “pop” - at the start of the envelope. But that transient is predictable, can easily be removed by raising the attack time slightly, and sometimes even be used for a musical effect on a percussive sound. The pop of the Hermods envelope on the other hand is more “glitchy” and unpredictable, too loud and non-musical and can’t be remedied with a longer attack. Unfortunately this makes the envelope of the Hermod unusable for me. I hope this can be fixed.
Now I’m using OS 2.00 and I’m still having issues with the envelope. The attack is really glitchy/noisy. It’s most apparent if you use it on a VCA with a sine wave as sound source. Other buzzier waves can mask the problem.
With the default attack amount of 35% the glitchiness is very apparent. If I raise the attack amount to 60% and above the glitchiness is no longer apparent. If I lower the amount below 12% the glitchiness instead turns in to a abrasive pop.
The problem is there even when the envelope is not reset abruptly. If I use a long release time the problem is much worsened.
If I use an external slew limiter on the CV the problem is much less pronunced. So that is a sort of band-aid solution.
I really hope this can be fixed!
I wonder if the envelope sound equally bad out of the new XP32 or if there is some hardware or software difference that make it sound better from those outputs?
