162 phase of a sound is completed. Normally the release phase is truncated by the next note on the queue. If H=0 then the note is treated as a ‘real’ note in the usual way. Typical values of C are: C=&201 A note on channel 1 to be synchronised with two others. C=&12 A note on channel 2 is to be played immediately regardless of what was in the channel 2 queue. A more succinct description of SOUND and ENVELOPE is given in the BASIC keywords chapter.
