One shot rec trigs behave as one shot trigs.
ARM arm all one shots of the track, on all patterns. Once a one shot is played, all other one shots of the track are disarmed.
So regular rec trigs can be more appropriate if you use several patterns. Btw a pattern change can be used to stop a recording.
Pattern 1 : rec trigs with Flex trigs
You can loop it, overdub, switch to pattern 2 when you’re done.
Pattern 2 : Flex trigs.
