v1.00 of the Line6 M-Series firmware is released.
Right now this has only one mode, and uses the RGB LED on the DMC-4 to indicated half / reverse / undo status.
1 Record / Overdub (hold for Undo)
2 Play / Stop
3 Play Once
4 Reverse (hold for half-speed)
In Reverse mode, the RGB lights blue. In half-speed, it lights red. If both half-speed and reverse are active, the light is purple. The RGB lights green for a moment after Undo is engaged, and if half or reverse are active, the LED just gets a bit brighter. It’s pretty easy to see in action.
Half-speed / reverse was chosen as a hold / tap instead of the stock Line6 DL-4 style tap and double tap since it’s very easy with the DL-4 to engage the wrong mode. In the next version, users will be able to choose double tap or tap-hold for half-speed at power-up.
Binary and source are on the Files page.
