First, please make sure you have the latest version of the MIDI Maestro app in the Apple or Google Play Store, the latest app version is 1.5.0
Then, please verify that your unit is on MIDI Maestro Firmware version 1.1.7, you can check this on the MIDI Maestro. Just go to the main menu and look at the bottom left screen to see what version you are on.
If you are not on 1.1.7 please follow these steps:
Update MIDI Maestro Firmware
Once you’ve verified the app is up-to-date, hold the pairing button on the MIDI Maestro’s back panel to enter pairing mode (You do not have to connect your phone directly to the MIDI Maestro using bluetooth in order to use it with the MM app, you just need to have your phone’s bluetooth enabled). Once the blue light at the top of the MIDI Maestro’s front panel is blinking, press Update Firmware on the MM app menu to update the MIDI Maestro firmware. If you’re up to date, the app will cancel the update and let you know you’re already up to date.
Update MIDI Maestro Default Modes
Note: Always update firmware before updating the default modes.
Occasionally, we will modify the Default Modes on the MIDI Maestro. In order to be sure you have the latest versions, hit Update Default Modes on the MM app menu. If you’re up-to-date, the app will cancel the update and let you know they’re already up to date.
As soon as you’re sure both are up to date, power-cycle (turn off and back on) your MIDI Maestro to finalize the updates.
Custom Modes
Note: Always update the Firmware and default modes before uploading your custom mode.
Once you have done this you can set up the expression pedal as follows, this is on the latest manual pgs 48 and 49
The app now has the function to set up what commands will be sent as the EXP pedal is manipulated. You can find this setup page in the menu.
First, select the increasing function, by default this is CC80
Next, decide on which channel it will be sent, by default this is channel 1
Do the same steps to set up the decreasing command
Likely both will send to the same channel
Click on the Default button to reset to the factory default values.
Remember, you must write the custom mode to the MIDI Maestro again for this change to be seen on the device. The EXP pedal will only exhibit this behavior when the custom mode is open on the MIDI Meastro. The Default Modes will still send the default values.
