I'm trying to create an original performance on the MX88 using Perf # 019 and when I change the layers in the performance to Part1: AP Concrt grand PNO and Part2: MFX Vibrancy and layering these parts I am losing Part 1 from key E3 down. With layer button on I only get Part 2 from E3 down and with layering off and part 1 selected I'm not hearing anything from key E3 down (keys are unresponsive). Everything works as it should above key E3. Am I missing some sort of parameter that is residual from the original performance settings ?
[LAYER] this button sets Part 1 and 2 to play across all keys
[SPLIT] this button allows you to set a Split Point, Part 1 above and Part 2 below the Key designated as the Split Point.
