JesterML Operating Manual MIDI Control

Velocity Sensing
Some keyboards have this function. It enables the musician to control the loudness
of the music by playing notes and chords delicately for soft music or hard for loud
music. The MIDI signal that is transmitted by such instruments consists of a Velocity
in the range 0 to 127.
If the instrument does not have Velocity sensing, the Velocity is fixed by the
manufacturer, often at 63 rather than 127 so that the music that is being played is not
too loud.

Summary
MIDI instruments send a stream of signals from their ‘OUT’ port. The signals sent
principally consist of Note On and Note Off messages which consist of Note Numbers
and Velocities.
There may be the occasional Program Change signal if the voice is changed.
MIDI and the JesterML
The JesterML is designed only to receive MIDI information. It cannot transmit MIDI
information to another device, although a ‘THRU’ port is provided to allow daisy
chaining.
MIDI Received
In Preset mode:
The first note of any octave will drive channel 1, the second note of any octave will
drive channel 2 and so on. The Receiving Channel is set to <--> by default. This
means that the desk will accept commands on any of the 16 channels. The velocity
information is used to determine the fade rate of a channel.
In Run mode:
The first note of any octave will drive submaster 1, the second note of any octave will
drive submaster 2 and so on. The velocity information is used to determine the fade
rate of the submaster.
You can disable MIDI control completely by setting MIDI to <Disabled> in Setup.
This is the default value, so if MIDI does not function, check it is Enabled first.
