Live Coding, Pdef, Quantization and timming

Just to clarify what I wanted. First I evaluate this pattern:

Pdef(\bz, Pbind(\amp, 0.125, \dur, 1/4, \degree, Pseq((1..16), inf))).play

And I would like to evaluate the following at any time, so that it would start to be played exactly when the \bz start its cycle.

Pdef(\qt, Pbind(\amp, 0.125, \dur, 1/4,\octave, 3, \degree,Pseq((1..16), inf))).play;

Therefore, both patterns would be paralell melodies separated by one octave.
