The 4 LED Buttons in the Grain Section change function while SOUND is held: SAMPLE toggles Live, LINK/LOAD toggles Choke, LINK/SAVE toggles Gate, REVERSE is disabled. Hold LATCH with any SOUND to set options for all Sounds. New: New MOD A/B Output Options: Threshold Gate (YELLOW) — sends a gate when the input signal passes the record threshold. Record Trig (PINK) — sends a trig when Recording Starts (Sampler) or when the recorder is recording (Looping Recorder). New: System Page Options: Grain Size Scaling — toggle ON to reduce SIZE range as RATE increases. Gate Delay — delays the GATE signal up to 8ms for slower CV sources.
