Yes, I use them through lpgs often, here is a recent one with two mangroves.
One formant out going through a Takaab lpg for the bass, a sine from 3S going into other lpj channel for variation. The higher tones are second mangrove square out into lpg and formant out direct to mixer (env into Air).
All envelopes are from jf, I think it was in shape/sustain, 3 triggers from varigate for the pattern.
I love jf, you can so easily switch from long notes to percussion in an instant as per second part of video, trigger patterns didnāt change.
