However, this app has a polyphony issue where releasing notes does not release the polyphony. If you hold a note/chord and play a single note riff on top, it will cut off the held notes… Also, cannot get the mod wheel to function at all. This app needs an update. Update: New update still contains polyphony issue. A reviewer on the mkii version has noted the same issue. ### 3/5 — Good sounds, Polyphony issue *2025-04-24* This synth sounds great, I love blending VA and FM.
