Author	Topic: why does this expression crash Kyma?
cristian_vogel Member	posted 14 April 2006 05:04 Still on the road to enlightenment - each time i try a simple bit of code, i seem to create unfathomable situations !! Please shine a light , so i can learn why! this simple expression in the frequency field of a generic source sample compiles no problem, but causes an Unhandled Exception "Kyma encountered this unexpected condition: Element not Found" - and crashes the DSP! \| direction scratchLength \| direction := ((1 bpm: (!BPM )) nextRandom abs * 8) of: #(-1 -1 1 1 1 1 1 1 ). scratchLength := ((1 bpm: (!BPM )) nextRandom abs * 4) of: #(0.03 0.05 0.07 0.09) removeUnits. ((0.6 * default) * direction) smooth: scratchLength s . If I make scarchLength a constant there is no problem whatsoever. why? IP: Logged
cristian_vogel Member	posted 14 April 2006 05:22 ok i've done it another way, ... scratchLength := ((1 bpm: (!BPM ) nextRandom abs) * 0.1) . ((0.6 * default) * direction) smooth: scratchLength s . ... Nevertheless , I still want to understand why my first version was crashing. Otherwise I'll never try to code anything more ambitious, and that would be boring! IP: Logged
yenorom Member	posted 14 April 2006 09:16 Hi Cris, the syntax looks ok to me but it crashes when I try it like you said. Strangely if you put the expression in a script and assign the sample's frequency param to the value from the script it works fine. Confusing???? IP: Logged
SSC Administrator	posted 14 April 2006 10:04 The error was due to an over-enthusiastic code optimizer--this has been fixed in our development version and should appear up on the tweaky soon (sometime over the weekend). New optimizer does not have the error and actually optimizes even better(!) Soon... IP: Logged
cristian_vogel Member	posted 14 April 2006 11:37 fantastic! i thought i was going backwards in my learning look forward to new update of compiler IP: Logged
