Hi, I am doing simple tests transferring SDIF files created in SPEAR into maxMSP using the above objects. I notice sharp clicks when a partial begins or ends, but only when there is more than one partial sounding. The click is a square cut-off, so I'm wondering if this in fact what is represented in the data, and the SPEAR DSP smooths it, or if it is a problem with one of the CNMAT externals (or the way I'm using them). I've attached a screen shot of a test file that plays smoothly in SPEAR and grittily in maxMSP, as well as the part of the patch I'm using to play it back. Any assistance would be gratefully received.
