The mp3's in this folder are examples of how my ASR is behaving. I'm not sure if this is typical or not and I'm hoping someone can help out. The patch is as follows: Keyboard 1V/Oct out to ASR input. ASR output 3 to VCO 1V/Oct input. Clocked with a 0-7V square LFO. The mp3 "ASR no clock" is the keyboard CV patched directly to the VCO. It's here just as a reference. Does your ASR behave like the samples I posted? It seems the output voltage jumps around. Is this normal? If not, then what are some suggestions/guesses about this. At first I thought this may be the clock signal feeding through to the output, but I think it's just as likely to be imperfection in the SH or output IC's. I had to replace the MC14xxx chips because they were getting hot. The replacements stay cool and the other ICs were replaced but the SH stages (LM356 / CA3140) still get kinda hot and so does the TL071 (these chips are perhaps more on the warm side, so maybe that's normal?). I'm using polystyrene caps for the SH's. TL074 for the quad opamp. +/-15V power. Thanks, p.
