Can I set up a Boss FS5U to tap tempo into an MC8? I’d prefer not to burn a switch for tap on the unit.
Yes that will work ( do note to use a TRS cable ). But to control tap tempo, you’ll need to program the omniport to “AuxSw”, which allows you to control one (or up to 3 depending on what aux switch you use) preset with an aux switch. Then you can program that preset like a regular preset to send PC/CC messages or any other function.
EDIT: I’m not sure how the FS5U is wired. The aux switch needs to be momentary and normally open. Has anyone successfully used the Boss FS5U?
