Unwanted default syth in pattern

Questions
1

I have a twofold question that I humbly beg for guidance on. Regarding ProxySpace: when fading from pattern to an empty Pbind.
there is the sound of the default synth. How to avoid this?
Also; what causes inconsistent (non working) fades?

~pat.fadeTime_(7)

~pat.play
(
~pat =
	Pbind(
	)
)

What is an inconsistent cross-fading? Most of the time, each sound has a very different envelope. Other times, the cross-fade curves were miscalculated. It’s hard to know what you are talking about.

Regarding the Pbind, yes, you get the default values for each argument. You need to set what you want if you don’t want that. That’s how it is. In this case, set \amp to zero.

Maybe you want a particular behavior. In this case, there are ways to make that more convenient to you.

Thank you! I should have figured that out re: \amp, 0
What I mean about non working fade
Is that even with a long fade time it instantly doubles over with no noticeable cross fade except one instance ends after the other begins.
Everything works well on one patch but a seemingly identical patch with different Synthdefs the crossfade is non existent.
The non working one Synthdef has OscN which uses a buffer. That might be what’s not fading.

Or, set \type to \rest.

\amp, 0 will play a synth and use CPU for it, but with 0 amplitude, so, silent.

\type, \rest will not play the synth in the first place, and not use the CPU cycles.

It does not matter. What matters is what argument key the synth responds to and what it does in the synth. Compare the SynthDefs and show what’s different here. Maybe that’s it.

Why would people need to pretend a Synth is running when nothing is happening?

A \Rest in the middle of a seq will be quiet; there is no way to change its amplitude and make it behave like a synth. Is there?

If you set the event’s type to \rest, then nobody is pretending anything – you’re explicitly asking for time to elapse without doing anything.

The pretense is with \amp, 0 – there, you’re pretending not to do anything while actually doing something that has no perceptible result.

Yes, it’s all about context. My brain sometimes thinks like a free improviser who wants things ready quickly at unpredictable times, and most of those processes are pretty cheap.

But there are other situations, of course. It all depends.

EDIT: also, on this topic, I never really found the rest implementation really “elegant,” it always looks strange to me )), the same with duration zero as a regular method.

This is the Synthdef that doesn’t crossfade correctly inside ~pat =Pbind(), I copied the buffer.alloc from a helpfile.

(
b = Buffer.alloc(s, 512, 1, {arg buf; buf.sine1Msg(1.0/[1,2,3,4,5,6,7,8,9,10])});

SynthDef(\nio,{ arg freq = 333, out = 0;
          var sig, fx;
              sig = COsc.ar(b,freq,2.2,0.2)*EnvGen.ar(Env.perc(0.02,2),doneAction: 2);
              fx = FreeVerb.ar(RLPF.ar(sig,LFTri.ar(1.66.reciprocal).range(666,999),0.02,0.25), 0.66, 0.68, 0.33);
          Out.ar(out, fx !2);
}).add
)

I think it will need an ‘amp’ control. Currently the Pbind has no way to control this synth’s volume.

Thanks, that does it. I’m going to include amp in the crucial argument category.
