Some have indeed build in midi but the majority uses envelope followers , and that's how it was mostly done in the old days .Igro wrote: Wed Nov 29, 2023 12:03 am So how do you trigger those external filters if you need to apply a fiter envelope on a key press? You can't really substitute a synth built-in filter. Those external filters with the transient detectors are just not working reliably.
Here's audio realism ABL going through arturia ms 20 (free) , the envelope follower modulates the cut off

And here ABL3 going through the drop
IN both cases abl3 cutoff remains completely open , what's verry important is a difference in dynamics levels -peaks ( using accent ) of the input signal , so the evelope follower has something to turn into a useful curve
