I just bought a Timefactor, and I really like the interface. However, I'm realizing that I'm gonna need an external tap tempo. It's gonn work best for me to leave it in bank/preset mode. I have no idea what tap tempo is best. Also, I'm in the market for a Strymom Flint. Is there one tap tempo that I can buy and use to control tap tempo in both the Timefactor and Flint? Or, am I better off buying two switches? One for the flint to control and tap and favorites and another for the Timefactor? Which switches are recommended for both of these pedals and where can I buy them?
