Note Toucher was originally designed to be used with a 5-octave keyboard. Users playing 4-octave controllers found they were unable to switch Note Toucher out of Thru-Mode back into Normal-Mode because that requires top-B to be held at the same time as bottom-C. Here is a standard MIDI sequence file that will load modified firmware into your Note Toucher to make it switch modes using the top-B of a 4-octave controller:
The LEDs will display the power-on splash to show you were successful, otherwise the velocity LEDs (not after-touch) will show an error code.
In the unlikely event of a power glitch while this MIDI sequence is playing, or you accidentally allow your DAW to send unrelated MIDI data while the firmware data is playing, your Note-Toucher will be left completely dead. But don’t worry, you can still play the firmware data to a dead unit and bring it to life again. In that case, just skip step-5 in the instructions listed above.
