… it depends on what instrument you’re playing. The incoming audio signal has to drop below a certain threshold before a new attack can be detected. Typically, percussive instruments are great for attack detection but f.i. vocals or string instruments not so much (unless some staccato is applied).
Anyway, I found that AD won’t trigger at all when the threshold is set to minimum so I fixed that. You can find the updated MacOS app on Github (don’t have a Windows machine here … will update that version later).
