MixerReceive — Receives an arate signal from a channel of a buss.
ibuss -- The number of the buss, for example the number of the instrument receiving the signal.
ichannel -- The number of the channel. Each buss has nchnls
channels.
asignal -- The signal that has been mixed onto the indicated channel of the buss.
Use of the mixer requires that instruments setting gains have smaller numbers than instruments sending signals, and that instruments sending signals have smaller numbers than instruments receiving those signals. However, an instrument may have any number of sends or receives. After the final signal is received, MixerClear must be invoked to reset the busses to 0 before the next kperiod.
