TempoBusClock a clock that synchronizes its tempo with the server

superclass: TempoClock

*new(control, tempo, beats, seconds)

return a new instance. 

control can be anything that responds to the message set(key, val, ...)

e.g. a Synth or a NodeProxy. The control key set is "tempo"

otherwise TempoBusClock works just like a TempoClock

// example

(

a = { |tempo=1| Ringz.ar(Impulse.ar(tempo), [501, 500], 1/tempo) }.play;

t = TempoBusClock(a);

Task { loop { "klink".postln; 1.wait } }.play(t);

);

t.tempo = 1.3;

t.tempo = 0.5;

t.tempo = 1.0;

// in ProxySpace, a TempoBusClock can be added together with a ~tempo NodeProxy:

p = ProxySpace.push(s);

p.makeTempoClock;

p.clock; // now the ProxySpace's clock is a TempoBusClock

~out.play;

~out = { Ringz.ar(Impulse.ar(~tempo.kr), [501, 500], 1/~tempo.kr) * 0.3 };

p.clock.tempo = 1.3;

// patterns and tasks are synchronized:

~out2.play;

~out2 = Pbind(\dur, 1, \note, Pwhite(0, 7, inf));

p.clock.tempo = 3;

p.clock.tempo = 1;
