So, I have an Arachnid board here waiting to be made. I am thinking about doing up a tap tempo arrangement for it. What I really want to do is that as it is a mono board, it is possible to use the second audio input as a tap input without worrying about the three pot inputs (or I suppose it could be a fourth pot input as well). The Arachnid board has the 2 inputs tied together (which makes sense if you are not using one). That will be easy to remedy with a Dremel. The thing is though that as the second input doesn't connect anywhere else, the only way to connect a tap switch to it will be to solder a lead directly to the IC pin - without shorting to any others. Am I insane to even think about trying it? Has anyone else tried a similar thing? How did it go? What are the tricks to help?
