I’ve discovered this issue on my DT about a year ago (can not confirm if it was there before the 1.50).
You play a sequence, adjust parameters of the fly and then press [FUNC+No] to reload pattern to its saved state. Sometimes I experinece very short moment of complete silence before pattern returns to its original form. Pattern stays in time.
Has anyone else experienced this behavior? Not an issue when practicing at home, but yesterday it happened to me on stage. Fortunately, once per set, so it looked more like a planned trick than failure.
