CHECK FIRMWARE VERSION OF YOUR INTERFACE
Actual firmware version is written on label on the interface’s CPU (see fig. 2). If the label is missing or
unreadable, it is necessary ro read the actual version number from the CPU. This is feasible via MIDI SysEx
communication.
1. Enable SysEx messages record / monitoring on your DAW / PC.
Send “SW Version Request” (i.e. [
F0 00 20 21 7F 44 50 04 00 68 F7 hex
]) SysEx message from your DAW /
PC to the interface.
2. Red LED on the interface board blinks.
3.
The interface responds immediately by “SW Version Response” SysEx message. Form of the message is:
[
F0
00 20 21 7F 44 50 04 vv xx F7 hex
] where the [
vv
] byte is the version number (e.g. [
10 hex
] byte represents
version "1.0", [
20 hex
] byte represents version "2.0", etc.).
