chnget — Reads data from the software bus.
Reads data from a channel of the inward named software bus. Implies declaring the channel with imode=1 (see also chn_k, chn_a, and chn_S).
ival -- the control value read at i-time.
kval -- the control value read at performance time.
aval -- the audio signal read at performance time.
Sval -- the string value read at i-time.
The example shows the software bus being used as an asynchronous control signal to select a filter cutoff. It assumes that an external program that has access to the API is feeding the values.
