How about this (server works... added a few other things - min and
max, numChannels, and startbus):
/*
// Utility class for a simple general volume
// andrea after Josh
// Volume.new(server, startBus, numChans, min, max); // min and max in
db
a = Volume.new; // use all defaults
z = {SinOsc.ar(440 * [1, 2], 0, 0.2)}.play(s)
a.close; // frees the Volume control. So does closing the window
// only control the left channel
a = Volume.new(startBus: 1, numChans: 1, min: -60, max: 12);
a.close;
z.free;
*/
Volume {
var server, <amp, <>window, <volume, spec ;
var slider, box, <lag ;
*new { arg server, startBus = 0, numChans = 2, min = -90, max = 6 ;
^super.new.initVolume(server, startBus, numChans, min, max) ;
}
initVolume { arg aServer, aStartBus, aNumChans, aMin, aMax ;
var cond;
cond = Condition.new;
server = aServer ?? {Server.default};
if ( server.serverRunning.not, { server.boot }) ;
volume = 0;
spec = [aMin, aMax, \db].asSpec;
//server = Server.default.boot ;
server.doWhenBooted({
Routine.run({
this.sendDef(aStartBus, aNumChans);
server.sync(cond);
{
this.gui;
this.volume_(0);
this.play;
}.defer;
});
})
}
// avoid confilcts with someone elses SynthDef called \amp
// by giving it a name that hopefully won't be used!
sendDef {arg startBus, numChans;
SynthDef(\volume_amp_sd_32768, { arg amp = 1, lag = 0.1;
ReplaceOut.ar( startBus, In.ar(startBus, numChans) * Lag.kr(amp,
lag) );
}).send(server);
}
play {
amp = Synth(\volume_amp_sd_32768, [\amp, volume.dbamp, \lag, lag],
target: 0, addAction: \addToTail);
}
// cleaner with MVC - in db
volume_ { arg aVolume ;
volume = aVolume ;
amp.set([\amp, volume.dbamp]) ;
box.value_(volume.round(0.01)) ;
slider.value_(spec.unmap(volume)) ;
}
lag_ {arg aLagTime;
lag = aLagTime;
amp.set([\lag, lag]);

Post by Andrea ValleJosh,
I was going to write exactly a little utility class with the
proposed mechanism, so I used yours (thanks!).
Now, I have to pass the constructor a server, I was thinking I could
refer to Server.default inside the class (i.e. without passing a
server), but doesn't work in this way.
What am I missing?
Best

// Utility class for a simple general volume
// andrea after Josh
/*
// a sound
{SinOsc.ar(mul:0.1)}.play
v = Volume.new(s) ;
v.gui ;
v.volume_(0.5) ;
v.volume ;
*/
Volume {
var server, amp, <>window, <volume ;
var slider, box ;
*new { arg server ;
^super.new.initVolume(server) ;
}
initVolume { arg aServer ;
server = aServer ;
if ( server.serverRunning.not, { server.boot }) ;
//server = Server.default.boot ;
server.doWhenBooted({
this.sendDef ;
}) ;
volume = 1 ;

sendDef {
SynthDef(\amp, { arg inbus, amp = 1;
ReplaceOut.ar( inbus, In.ar(inbus, 2) * amp );

I did this interview where I just mentioned that I read Foucault.
Who doesn't in university, right? I was in this strip club giving
this guy a lap dance and all he wanted to do was to discuss Foucault
with me. Well, I can stand naked and do my little dance, or I can
discuss Foucault, but not at the same time; too much information.
