About this Guide
This manual contains all the information you need to be able to write software that is customized
for SL MkIII.
Number Systems and MIDI conventions
We always express MIDI channels starting from 1, so MIDI channels range from 1-16. MIDI messages
are also expressed in plain data, with decimal and hexadecimal equivalents. The hexadecimal
number will always starts with ‘0x’. For example a Note On message on channel 1 is signified by
the status byte 0x90.
InControl View
It is possible to access the
InControl
view by pressing the InControl button which is used to take
control of Ableton, Logic, Reason, and all other DAWs with HUI support.
In this mode, MIDI messages are sent from SL MKIII when pressing buttons, turning knobs, moving
faders and pressing keys. Sending specific MIDI messages to the device can update the colour and
status of the LEDs and screens.
This means that screens and LEDs can be controlled using any software or hardware able to send
MIDI messages using the
InControl API
.
InControl API
The
InControl API
can send and receive Control Change, Note, SysEx and NRPN messages.
Messages To The Device
This section shows how to set the status of the LEDs (see List Of Available Controls) and put data
on the screens.
All MIDI messages must be sent to the InControl USB port.
LEDs
LEDs can be utilised in three ways:
solid
colour,
flashing
between two colours, and
pulsing
one
colour.
To set an LED to a
solid
colour, a message corresponding to that LED should be sent on channel
16.
