control bus in a proxyspace (how to)

[paganmuzak]

Hello everyone,
I ask again a question of my previous post in which I have not yet found a
solution.
I am trying to use a control bus with a proxyspace but with the following
code I get an error message.
Where am I wrong?
Thanks in advance

c = Bus.control(s, 24);
o = OSCFunc({ arg msg;
(msg[2].value.asString++":"++msg[3].value.asString).postln; c.setAt(msg[2],
msg[3].value)}, '/ID', nil, nil, ['0', nil, nil] );
p = ProxySpace.push();
~grano = { |freq = 0.5| SinOsc.ar(freq*1000) };
~grano.play;
~grano.map(\freq, c.index);

but I get the following error when evaluate the last line of code
(~grano.map(\freq, c.index);):

ERROR: map: not a node proxy

^^ The preceding error dump is for ERROR: map: not a node proxy

This appears to be a limitation of the version of JITLib that is
included with SC 3.6. NodeProxy:map expects node proxies (in fact,
BusPlug or any subclass) -- Bus objects or bus indices are not
permitted.

You'll have to use the alternate way to map a bus -- that is, *set*
(don't map) the control to the bus's mapping string:

~grano.set(\freq, c.asMap);

[adc]

you can also just make a kr nodeproxy and map that, e.g.

~freq = { |freq = 300| freq };
~snd = { |freq = 100| Blip.ar(freq, 20) * 0.1; };
~snd.play;
~snd.map(\freq, ~freq);

// add some lag for smoothing later?
~freq = { |freq = 300| freq.lag(0.1) };

best
