How do you minimize your A/D conversions, or even keep track of them? I wish there were some standard for controlling tracking signal chain filter latency and # of A/D conversions similar to digital interfaces and FOH networks. A nightmare signal chain can easily be assembled: 1) a preamp pedal with a cab sim IRR filter 2) analog into a 2nd digital effects processor 3) analog into a digital mixer 4) analog into a P/A speaker with digital EQ, crossovers and limiting. Geez that's 4 A/D samplers and 4 D/A conversions, no? Latency--who knows? Ideally I would have only 1 A/D conversion and 1 D/A conversion. Many updated pedals these days seems to add IRR filter support.
