Afaik the OT doesn’t work with ‘mono’ samples, aren’t they sorta converted to stereo (or 2 channel) once loaded (all tracks are stereo)… Maybe a nuance which is clouding expectation. Fairly sure the ‘pingpong’ worked out as i expected. Curious to investigate again[/quote]
yep - the issue here is that you’re actually hearing a ping pong delay, but as the left and right channels are the same, you can’t easily tell (unless you adjust the balance (not PAN) - easy to verify with an obviously stereo sample, record a note on left channel and a different note with different dynamics on right at same time - then fire through the delay with default balance - if X (crossover) is off you’ll hear that the delay is true stereo, if X is on you’ll hear the echoes alternately swap sides - so the confusion is that you’re expecting the ping pong to work as a mono input ping pong would

if you adjust the balance on the stereo sample now, it’ll emphasise either of the notes and the ping pong will be even more obvious
