Plotting a UGen without waiting

… and a second time “oh dear” …

File writing conventions have changed … on my old mac above example works but not on the other machine with OS 10.13.6, we have to specify the path to the osc file now, e.g.:

// helper synthDef to indicate storage of temporary SynthDef of passed function

(
SynthDef(\finishedStore, {
	SendReply.ar(Impulse.ar(0), '/finishedStore');
	Line.ar(dur: 0.001, doneAction: 2);
	Silent.ar
}).store
)


(
~plotNRT = { |function, duration = 1, numChannels = 1|
	var soundFile, array;
	var synthDef = function.asSynthDef;
	var dateString = Date.getDate.stamp;
	var renderString = "render_" ++ dateString;
	var soundFileName = Platform.recordingsDir +/+ renderString ++ ".aiff";
	var options = ServerOptions().numOutputBusChannels = numChannels;
	var oscFunc = OSCFunc({ |msg|
		// produces score and renders aiff
		Score.recordNRT(
			[
				[0.0, [\s_new, synthDef.name, 1000, 0, 0]],
				[duration, [\c_set, 0, 0]]
			],
			("~/" ++ renderString ++ ".osc").standardizePath,
			soundFileName,
			options: options,
			duration: duration,
			// after rendering is finished we can plot
			action: {
				soundFile = SoundFile.new;
				soundFile.openRead(soundFileName);
				{
					array = FloatArray.newClear(soundFile.numFrames);
					soundFile.readData(array);
					array.plot;
					soundFile.close;
				}.defer

			}
		);
	}, '/finishedStore').oneShot;
	// triggers synth finishedStore which triggers OSCFunc
	synthDef.store(completionMsg: [\s_new, \finishedStore, -1]);
}
)


// plot 10 seconds
// audio file stored in SC recordings directory

~plotNRT.({ LFDNoise3.ar(1) }, 10)

This issue is worse than the other, I’m afraid it is affecting a lot of help files and users’ code in general.
