=> R0 = schedule period or
-1 to synchronise with the previously scheduled event
-2 immediately schedule
R1 = 0 Schedule Sound_ControlPacked
&yFxxxxxx Schedule SWI number &xxxxxx (y irrelevant)
R2 = R0 for SWI
R3 = R1 for SWI
<= R0 = 0 success
< 0 failure
This call schedules a SWI on the queue. Typically this is Sound_ControlPacked, but any SWI may be scheduled provided:
· entry is R0, R1 as specifed, R2-R7 = 0
· if R0 or R1 point to buffered parameters, these must be available when the SWI is called
The X form of the SWI is forced, return parameters are discarded.
When the beat counter is enabled the schedule period is measured from the last bar start; when disabled from the time of this SWI call.
