How do I use the MIDI commands in The Grid 2?

The Grid 2 can control any connected MIDI devices. MIDI (or Musical Instrument Digital Interface) is a series of simple commands developed in the early 1980’s to control electronic instruments. This has grown into a universal way of accessing many devices as well as playing back audio. 

MIDI Note command 

The MIDI Note command will play a single MIDI note. Select the note that you want, and the channel (instrument) to play it on. 

The MIDI note command

You can have more than one MIDI device connected at a time (e.g. drum machine and synthesiser) and each one gets a different channel. 

MIDI Note On / Off 

If you want to take more control, the Note On and Note Off commands can be used to specify when a note starts or stops. For example, to play a chord you could use 3 Note On commands, then wait, then 3 Note Off commands.

You also get to specify the velocity – how quickly the note fades. 

Please be aware that every Note On command should be followed by a corresponding Note Off command at some point afterwards to stop the sound playing. 

MIDI note aftertouch 

This is used to change the pressure applied to a key for compatible instruments. It will mimic a light press or a hard press of a key.

MIDI controller message 

This sets a value for a MIDI controller. This depends on the MIDI device that you are using, but it can set values such as the tempo or the volume.

MIDI program change 

For most MIDI devices, the program is the instrument. This command tells your MIDI device to change program.
