@RonHerrema Hello Ron...... that is strange that only one student has this error. It is very good news as well for all of the others!
I cannot reproduce that error, but I cannot read the last few characters of the error message......
I can read wav/selection/* something...... is it 'asterix" "double-quote" after the forward slash?
If so then they are (normally) illegal characters in windows file and folder names, and I wonder if that student is running a different os?
David.

Thanks, David - she's going to have a look at the file names. I think the student is running Windows.

cheers

Interesting topic, guys!
Do I understand right, that you try to assign numbers to samples that are used to select them out of a certain folder?
Loading audio files like that could easily be used for a sampler in the style of
"ParamDrum" http://reaktortips.com/2011/03/paramdrum-3-is-here.html
or "S-Layer" http://twistedtools.com/shop/reaktor/s-layer/ .
I could also imagine loading sample-combinations using an interactive genetic algorithm that lets you listen back new sample combinations in a certain mixture... really inspiring.
Think of combining that sample loading mechanism with a sequencer using a Markov-chain-matrix like used in
"sector" http://createdigitalmusic.com/2014/02/sector-stuttering-stochastic-sample-slicer-using-probability-curving-lines-ipad/ !
wicked...

Yepp...I guess I'll use this stuff, too.
Great work!
