Timbre balance, timbre type, timbre edit and voice spread are received by the prologue-16 only; the prologue-8 sets them in Program Edit mode. The prologue-16 has 16 voices (8 + 8 with two timbres), the prologue-8 has 8 (4 + 4). Control changes 96, 97, 103 and 104 are in the implementation file but not in the owner's manual chart; the chart also lists 121 (reset all controllers), which the implementation file does not. The manual does not say which controls the sub timbre accepts on the Sub CC channel. The prologue has no NRPN. Panic sends Note Off, All Notes Off (123) and All Sound Off (120); both are in the prologue's recognized list.
