Do I need to use a TRS cable with Conduit, or can I use a TS cable?

For any jacks that are configured for GREEN-TIP SEND configuration for pedals that receive MIDI IN data on the TIP of the cable connection (such as Strymon pedals), if you are only sending MIDI data to the pedal(s) without receiving MIDI data back, you can use mono TS (TIP/SLEEVE) cables to connect the pedal(s) to Conduit.

Also, in AMBER-TIP and RING SEND configuration, you can use mono TS cables connected to the TRS Y-Cable adapter plugged into the jack set to that mode for connecting up to two pedals that receive MIDI IN data at the TIP of the cable.
