Double trig/flam problem with phrase

Hi all!

I made a phrase with a break and play it from Ableton Live using a midi track, and the audio goes through Rewire back to Ableton. Thing is, every other repetition a double trig/flam like sound occurs at the start of the phrase, even the metronome in Renoise sounds like it’s flamming. First triggered phrase sounds good, then bad, then good and so on.

Can’t get my head around this one! :exploding_head:
