Patching input to output (see also soundIn).

> audition (out 0 (in' 2 AR numOutputBuses))

Patching input to output, with delay.

> let {i = in' 2 AR numOutputBuses
>     ;d = delayN i 0.5 0.5}
> in audition (out 0 (i + d))

Write noise to first private bus, then read it out.
The multiple root graph is ordered.

> let {n = pinkNoise 'α' AR
>     ;b = numOutputBuses + numInputBuses
>     ;wr = out b (n * 0.3)
>     ;rd = out 0 (in' 1 AR b)}
> in audition (mrg [rd,wr])

There are functions to encapsulate the offset calculation.
(There is also a firstPrivateBus value.)

> let {n = pinkNoise 'α' AR
>     ;wr = privateOut 0 (n * 0.3)
>     ;rd = out 0 (privateIn 1 AR 0)}
> in audition (mrg [rd,wr])

Set value on a control bus

> withSC3 (send (c_set1 0 300))

Read a control bus

> audition (out 0 (sinOsc AR (in' 1 KR 0) 0 * 0.1))

Re-set value on bus

> withSC3 (send (c_set1 0 600))

Control rate graph writing buses 0 & 1.

> audition (out 0 (mce2 (tRand 'α' 220 2200 (dust 'β' KR 1)) (dust 'γ' KR 3)))

Audio rate graph reading control buses 0 & 1.

> audition (out 0 (sinOsc AR (in' 1 KR 0) 0 * decay (in' 1 KR 1) 0.2 * 0.1))
