@OldmanChompski Yeah, It used to work with a depth of 0.5, but now it needs to 1 or higher. I did the original video btw 
Can you confirm that when you’re doing the ping pong trick and the sample is playing in reverse (REV.L) and play head hits the start, the sample jumps to the end mark and continues to play backward, then when the LFO changes the direction to FWD.L it plays forward until it hits the end marker and again wraps to the start marker? That is the bit that is broken for now on DT1.
Although if just using FWD.L or REV.L on its own (without LFO), then looping in just 1 direction works as expected.
