StompMIX 4 Version v1.00 User Manual

StompMix 4 - Firmware V1.01

“Updating unit will Erase all saved Pre-sets.”

Download and Run the .exe file, and follow the instructions.

1) Make sure unit is on MAIN Mix screen.

2) Connect the StompMix 4 USB

3) Run the update, (few seconds), it will ask you to wait for the StompMix 4 to re-initialize, but this will erase all your previous pre-sets.

4) once unit finish the updated, it will return to the Main MIX screen, you can check the Version by HOLDING down the SYSTEM switch.

What is NEW – This is to bring StompMix 4 units to firmware version 1.01. Changes from 1.00 are the following:

– Added popup window for memory recall via foot switches. When the foot switches are assigned to “M- M+” if pressing a foot switch results in a memory being loaded (at least two memories are not empty), a page pops up showing the number of the recalled memory in large font.

– Added “1-4   FX” mode in the footswitch assign list. In this mode footswitch A mutes all channels at once and footswitch B mutes both the reverb and the delay at once.

– Added “M<  >A” mode to the output routing list for both Out1 and Out2. In this mode the left side of the output jack gets a mono version of the main mix, while the right side gets a mono version on the aux mix.  – you can now route your Dry signal using the Aux Mix and send it out on OUTPUT 1 MONO Right.
