allocate a buffer (id = 0) for writing into

write into the buffer (id = 0) with a bufWr

>         o = sinOsc AR (lfNoise1 'α' KR 2 * 300 + 400) 0 * 0.1

>     in mrg2 (silent 1) w

read it with a BufRd

>     in bufRdL 1 AR 0 (phasor AR 0 (bufRateScale KR 0 * rt) 0 (bufFrames KR 0) 0) Loop

set read & write rates independently
