Hi, list! It seems that Rhodey needs some attention. When I make it sound, using 1 => rhodey.noteOn; then let it sound it's fine (and decays on it's own like it should) but when it gets a 1 => rhodey.noteOff; before it has decayed it will instead drone on forever at it's current timbre and volume. 0 => rhodey.noteOn; does work, if a little abruptly. This is unlike the behaviour of the other STK fm-based instruments so I think it's a bug. It sounds to me like the issue is in envelope behavour as Rhodey normally keeps evolving it's sound over the cource of a note but once it gets stuck it stops evolving, aside from what I think is the LFO. I just checked Wurley for completenes's sake and Wurley has the same issue. BeeThree, for example, is fine, as is HevyMetl. Yours, Kas.
