I've been thinking a lot about how to make one of these for a few days since I'm piling up the pedals and want to be able to use them better together.
For those of you that aren't familiar with the Carl Martin Octaswitch, it works almost like a 'programmable' loop selector. You can assign different loops to eight footswitches.
I think I have a rough idea together for how to do this.
If you look at this article by RG:
http://www.geofex.com/Article_Folders/multivol/multivol.htmThe part at the bottom shows how to get a steady signal from one and only one momentary switch at a time. It seems to me that if you were to rout each of those steady signals to one of eight DIP switches, you could send that signal on to a non-latching relay at each loop. Just set the dip switches to which loop you want each switch to put into the signal and you have a 'programmable' set of momentary stomps with true-bypass loops.
Seems like you could do it with a couple really cheap chips plus all the switches, jacks, DIPs and relays - and a lot of time.
Is this right or am I missing something?
Also, I've got a plan for how to do away with all the dip switches and replace them all with a single rotary encoder. The problems I have with that Idea is that right now it would require 29 chips and wouldn't 'remember' the settings after the power is turned off.
