Hi,
Having had the H9 for several years now, I never found much use of the ADSR shape in the modulation algorithms. The envelope follower seems much more responsive and has a better feel than the ADSR, perhaps because the Attack, Decay, Sustain, and Release parameters are fixed. Is there any chance these parameters will become available in an updated version of the Modfactor algorithms? Better still, would it be an idea to replace the ADSR with an reversed envelope follower? Of course, if there is something I am missing with the ADSR setting, I would love to hear so…
