I see no problem. I would generate a frequency and a volume control curve for each channel and apply this to the played instrument, then I would mix it. It is the strength of Haskell to separate everything into logical steps and let laziness do things simultaneously. Stream fusion can eliminate interim lists, and final conversion to storable vector using http://hackage.haskell.org/package/storablevector-streamfusion/ can eliminate lists at all. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
