Hi all, I’m trying to get the filter module to modulate using Aftertouch, but it’s not triggering. Filter works with all other modulations, and AT works on all other modules, except for this routing. Anyone else have this? ---

Thanks for reaching out, and sorry to hear you’re experiencing this issue. We’re unable to reproduce the problem on our end, could you let us know which version of your DAW you’re using, and whether you’re running the latest version of Soundbox (1.0.7)? ---
