<p>Umm, well... to answer the above question, I've run atari punks, SX-150, a Casio SK-1, a police scanner and an ancient reel-to-reel tape deck through the input. All of them work fine at various input levels from the instruments and the input volume levels. So, in other words, everything seems to be working normally. The only thing I'd say is that they all seem to be rather loud compared to the oscillators.</p>
<p>Are you saying we need to flip C5?
