Sound_InstallVoice
(SWI &40183)
| Entry | |
|---|---|
| R0 | Pointer to Voice Generator |
| R1 | Voice slot (1-32), or 0 to install in next free slot |
| Exit | |
|---|---|
| R0 | Pointer to name of previous voice, or null terminated error string if R1 = 0 |
| R1 | Voice number allocated, or 0 if unable to install |
Use
Used to add a Voice Generator to the table of available voices.
Notes
If an error occurs, this SWI does not set V in the usual manner. Instead R1 is zero on exit, and R0 points directly to a null-terminated error string.
If an attempt is made to replace an existing Voice Generator R0 will point to the previous Voice Generator name, R1=0 and the new Voice Generator will not be installed.
