Not in my experience. If you had the sequencer running when you hit Stop, when you hit Play, any loops you had playing on any Pickup Machine track will resume playing, without you having to add a trig to the Pickup Machine track.

By default, the sequencer will sync to the Master Pickup Machine if you had the Pickup Machine already looping before you start the sequencer. No pedal required. If you don’t want the sync, then you have to change a config setting (I forget exactly which, and where).
