Key Control

Map your MIDI controller keys to a given Scale and Key

Keep your keys 'In Key!'

Key Control is a MIDI device that maps your keyboard controller or synthesizer to a chosen Key and Scale. The white keys will play all the notes in the desired Key & Scale (removing all unused notes), while the black keys will play chords within the Key & Scale. Choose between 11 scales and all 12 keys.

Simply hook up the Key Control between your keyboard controller and your desired MIDI destination (computer, synthesizer, sequencer, etc) via standard 5-Pin MIDI DIN cables. Or put your synthesizer in "Local OFF" mode and send the MIDI out from your synth through the Key Control and back into the synth, to always play 'in key.'

With a fast and easy 2 knob interface, you can quickly dial in one of a possible 132 possible key and scale combinations and get down to making music fast and with no fuss.

In “Chromatic” mode, 127 MIDI notes are passed through unchanged, while the “Key” knob will transpose the incoming MIDI notes up to 11 semi-tones.

MIDI notes are changed depending on the Key & Scale chosen, but all other MIDI data passes through unchanged, with low latency and fast operation.

Compact but tough aluminum case. Ships with 9v power supply.

  • Major
  • Minor

NOTE: A couple of users have had some issues using the Key Control with certain DSI synthesizers in 'stand alone' mode, namely the Prophet 12. The problems only arise when feeding the MIDI out of the P12 into the Key Control and then back into the P12, there are no problems when using a seperate keyboard controller or synthesizer. All other synthesizers have been reported to work fine.
