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.
