SA242 Gemini Chorus User’s Guide 33

App. Channel numbers in MIDI use zero-based counting, so MIDI channel 1 is described as 0 in

hexadecimal, MIDI channel 2 is described as 1 in hexadecimal, and so on, concluding with MIDI

channel 16, which is described as F in hexadecimal. A continuous controller message starts with a

hexadecimal B and is followed by the channel number (0 through F). So, the command byte from

your MIDI controller should be formatted as shown in the following table:

MIDI Channel

(Decimal)

CC Command Byte

(Hex)

Each continuous controller command byte is followed by two bytes, the CC number and the value. So,

each CC message consists of a total of three bytes. If the Gemini is not responding to MIDI, make sure

that your MIDI controller is properly configured and sending messages in the format described above.
