  • Page 3: Introduction And Setup

    1. Introduction and setup MIDI (Musical Instrument Digital Interface) is a standardised communication protocol that enables digital devices to communicate and allows one piece of equipment to control another. The SQ sends and receives MIDI over USB (via the USB-B port) as well as over ethernet (using MIDI over TCP/IP via the network port).

  • Page 4: Midi Channels

    1.2 MIDI channels There are 16 MIDI channels available, and the SQ makes use of 2 of these, one for mixer control and one for use with the DAW Control Driver. Press the ‘Utility’ screen key, then touch the ‘General’ tab followed by the ‘MIDI’...

  • Page 5: Types Of Message

    1.3 Types of message MIDI messages can be presented in different ways in various hardware and software, including plain text, binary, decimal and hexadecimal. As an example, here are four representations of the same message: Plain text MIDI Channel 1, C-1, Note on Binary 1001 0000 0000 0000 0111 1111 Decimal 144 0 127 Hexadecimal 0x90 0x00 0x7F...

    Control Driver DAW Control MIDI 1 to 4 PC / mac SQ-5 / SQ-6 / SQ-7 In addition to the translations, a ‘MIDI Thru’ option is provided which allows MIDI messages to pass through unaffected. This is the easiest way to communicate with an SQ on a network by using MIDI over TCP/IP.

  • Page 7: Midi Faders And Soft Controls

    2. MIDI Faders and Soft Controls 2.1 MIDI faders The SQ has 32 freely assignable MIDI fader strips. Refer to the SQ Reference Guide for information on strip assignments. Each strip sends and responds to the following messages sent on the ‘MIDI DAW Control Channel’: MIDI Mute Key...

  • Page 8: Soft Keys And Footswitch

    2.2 Soft Keys and Footswitch The SQ-5 features 8 assignable Soft Keys, while the SQ-6 and SQ-7 both feature 16 assignable Soft Keys and all SQ models feature a dual footswitch input. Any of these can be assigned the following MIDI functions:...

  • Page 10: Soft Keys

    3.2 Soft Keys The SQ Soft Keys can be controlled using standard MIDI Note On/Off messages, allowing the control of many more internal functions of the SQ by proxy.  The SQ does not send note on/off messages when a Soft Key is pressed unless the Soft Key is set to a MIDI note on/off function.

  • Page 11: Mutes

    3.3 Mutes The SQ sends and receives absolute On or Off mute messages. It will also toggle the mute state when either an increment or decrement message is received. MSB and LSB are a parameter number for the channel you wish to mute or unmute.

  • Page 12: Levels

    3.4 Levels Levels can be set using either absolute values or in relative 1dB increments/decrements. MSB and LSB are a parameter number showing where the signal is being sent from and where it is being sent to.  MSB/LSB parameter numbers are shown in the reference tables.

    3.6 Mix Assignments The SQ sends and receives absolute On or Off assign messages. It will also toggle the assign state when either an increment or decrement message is received. MSB and LSB represent a parameter number showing where the signal is being sent from and where it is being sent to.

  • Page 16: Getting Values

    3.7 Getting values A ‘get’ command can be sent to the SQ in order to return the current value of any mute, level, pan/balance or assignment parameter listed in this document. MSB and LSB represent the parameter number of the value being requested, followed by a data increment with value 7F (i.e.
