Have an Akai 4000s Ewi midi electronic wind controller and sometimes low midi notes play on their own and stick – usually when turning the instrument off. Anyone encounter this or know a fix?
Answer: This is normal with most electronic instruments. The fix is when shutting down start with the amp first and go backwards in the audio chain. All midi devices from time to time produce stuck notes. Must midi patchbays have a “all notes off” buttom for this reason. Sometimes it just helps to switch the sound on the synth and the stuck note stops.
Stuck notes are usually caused by switching something while a note is playing. In the MIDI protocol synths communicate by sending and receiving “note on” and “note off” and sometimes the “note off” just gets lost.
