Sometimes strange things happen in the studio. Most of these nerve-wracking issues are caused by a silly thing. Maybe, you already experienced the following one:
You are playing an external synth or plugin synth from the Accelerator keyboard and the sound of the external gear is randomly changing or the MIDI input monitor of your DAW is receiving MIDI controller data even when you are not touching the Accelerator.
In most cases problems like that are caused by the motion sensing circuit of the Accelerator. The sensitivity of this circuit is very high and even the smallest changing of of the three position angles of the keyboard are converted into MIDI controller data.
It is an easy task to lower the sensitivity of the circuit. If you are not using the motion sensor at all you should disable it completely. Please just follow the steps below:
1.) Push the [SYSTEM]-button.
2.) Push the [ARROW-DOWN]-button 9 times.
3.) A view monitor for sent controller messages shows up.
4.) The first display encoder is assigned to the sensitivity control. Turn it down to 1.
5.) Push any other button (PERFORM, PROGRAM, BANK, PART SELECT etc.) to leave the system menu again.
The problem should have been solved by the action above.
PS.: There is a parameter called „ACC SEND: ON/OFF“. Unfortunately this looks like a filter for the sensor data but is not doing anything at the current version of the firmware.

This article is the starting point of a series of troubleshooting guides for Accelerator users.
You maybe experienced something like that yourself in the past. You start diving into menus and try to explore something new by trial and error. After a while you are realizing that something went wrong but you can’t exactly recapitulate, what you did last before the problem occurred. In the case described in this article the problem is a silent keyboard area – independent from the performance or the single sound you are choosing, a section on the keyboard does not trigger the voices of the synthesizer anymore.
The good news is – the keyboard in 99,9 % is not defective and you have not destroyed that thing!
The Accelerator has a realtime transpose function for the step sequencer. This function allows for transposing sequences by hitting transpose keys on the keyboard. The transpose function can be assigned to a keyboard area. This keyboard area does only control the pitch of the sequence playback but not the synthesizer engine anymore. There are different ways specifying the transpose keyboard section but only one works for all presets and even after rebooting the unit. It’s the global transpose function in the system menu.
If you want to use the whole keyboard again please follow the instructions below:
- Push the [SYSTEM]-button.
- Push the [ARROW DOWN]-button two times.
- Push the left display encoder button to toggle the global transpose function on/off. When set to „Off“, the keyboard should work again over the entire keyboard range.
