Topic/bounded controls: cleaned up branch ready.

[telephon]

This is a cleaned up version of the old branch bounded-controls. It fixes #1252.

[telephon]

Here are the tests from the discussion:

s.reboot

(
var target = Bus(\audio, 2, 4, s),
bus,
freq = 6,
synthTarget = s.defaultGroup;

c = s.controlBusAllocator.alloc(5);

bus = Bus.control(s, 4);

b = bus;

x = Synth.basicNew(\x, s, 1000);

SynthDef(\x, {
    arg bus, kbus, t_trig;  // t_trig lets client control timing/reset of Peak
    var sig;
    sig = Peak.ar(In.ar(bus, target.numChannels), T2A.ar(t_trig));
    Out.kr(kbus, sig);
}).send(target.server,
    x.newMsg(synthTarget, [\bus, target.index, \kbus, bus.index, \freq, freq],
        \addToTail).debug("the outgoing arg list is correct"));
)

// should return:
// the outgoing arg list is correct: 9, x, 1000, 1, 1, bus, 2, kbus, 10, freq, 6

s.queryAllNodes(true);


// shouldn't change frequency
x = {|mul = #[0.1, 0.2], freq = 440| SinOsc.ar(freq, 0, mul) }.play
x.set(\mul, [0.2, 0.1, 800])

// shouldn't change frequency
a = Bus.audio(s, 2);
x = { Out.ar(a, PinkNoise.ar(1 ! 2) * LFNoise1.kr(1)) }.play;
y = {  Ringz.ar(\in.ar, [700, 1400] * (\freq.ar + 1), 0.1) * 0.1 }.play;
y.map(\in, a);

ping?

[timblechmann]

what is index, what is mIndex? m is a common prefix for "member", though both are members. maybe there are more expressive names?

[telephon]

better? For index I didn't see a much better name. Maybe index_in_synthDef, but that would make it harder to read even.

[timblechmann]

great, thanks!

[telephon]

if it is ok, could someone else be so kind and merge?

[telephon]

Ok, I'll take responsibility, before it gets stale.

[LFSaw]

thanks for all the effort to merge in topics, @telephon !
