| Entry | |
|---|---|
| R0 | 0 to return current beat number |
| -1 to return current bar length | |
| <-1 to disable beat counter and set bar length 0 | |
| +N to enable beat counter with bar length N (counts 0 to N-1) |
| Exit | |
|---|---|
| R0 | current beat number (R0 = 0 on entry), otherwise the previous bar length |
Use
Sets or reads the beat counter or bar length.
The simplest use of this call is to read either the current value of the beat counter or the current bar length.
When the beat counter is disabled both it and the bar length are reset to zero. All scheduling occurs relative to the time the scheduling call is issued.
When the beat counter is enabled it is reset to zero. It then increments, resetting every time it reaches the programmed bar length (N–1). Scheduling using Sound_QSchedule then occurs relative to the last bar reset; however, scheduling using *QSound is still relative to the time the command is issued.
