Re: [sc-users] NRT crashing

[David Etlinger <etlinger@xxxxxxxxxxxxxxxx>]

Here's a stripped-down version of my code. I've been sprinkling wait
statements throughout so they've been accumulating.

Thanks,
David

Task{
gridN.do {
	| n_x |
	
	var x = xMin + ( (n_x/(gridN-1)) * (xMax - xMin) );   // in meters
	
	gridN.do {
		| n_y |
		
		var yFrom = minFrom + ( (n_y/(gridN-1)) * (maxFrom - minFrom) );
			
		score = Score.new( baseOSC.score );
		
		params = params
			++ ( \xPos: x, \yFrom: yFrom );
		
		score.add( [ t, [ \s_new, gridSynth, -1, 1, 40,
					params.asArgsArray ].flatten ] );
		score.sort;

		( "\nStarting rendering: [" ++ x ++ ", " ++ y ++ "]" ).postln;
		
		tmpFile = n_x + n_y ++ ".tmp";
		outFile = n_x + n_y ++ ".wav";
		
		renderFn.( score, tmpFile, outFile );
		1.2.wait;
	};						//gridN y-vals
	1.5.wait;		//extra waiting help crashes??
};						//gridN x-vals

{	//clean up tmp files once all rendering is done
	( "rm *.tmp" )
		.unixCmd({
			"\nRun complete!\n".postln;
		} );
}.defer( dur );
}.play;

renderFn = {
	| score, tmpFile, outFile |
	
	var cmd;
	
	//can't use score.recordNRT since we need both escaped and unescaped osc
file path
	//edit: possibly putting escaped quotes, "\"" around file names could
alleviate
	// the need to escape chars, but I've already done it this way.
	score.writeOSCFile( tmpFile, 0, nil );
	0.2.wait;
	cmd = ( Score.program + "-N" + tmpFile.escapeChar($ )
		+ "_"    //blank input file
		+ "\"" ++ outFile ++ "\"" + 44100 + "WAV" + "int24"
		+ o.asOptionsString
	);
	
		p = Pipe( cmd, "r" );
		l = p.getLine;
		while( { l.notNil }, {
			//process each line based on its text
			l = p.getLine;
		} );
		
		0.1.wait;
		( "/Applications/SoX/sox " ++ "\"" ++ outFile ++ "\""
		+ "\"" ++ outFile.removeExtension ++ ".dat\" trim "
		++ (t*44100) ++ "s 6000s" ).unixCmd;
	
	//let this render finish before starting a new one
	( dur * 2.5 ).wait;
};
