Parts (Shift + Fader Button 6/7) let you split or layer the keys to send MIDI messages on different MIDI channels - this is useful for controlling different hardware or software instruments at the same time.

The MIDI channels for the two Parts (A and B) can be individually set in the Settings menu - by default, Part A will output on MIDI channel 1, and Part B will output on MIDI channel 2.

For example, if you have an instrument set to MIDI channel 1, you can play it using the keys whilst Launchkey is set to Part A (default). If you have a different instrument set to MIDI channel 2, you can switch to play that other instrument by switching to Part B (Shift + Fader Button 7).

In the project template, when both tracks are record-armed/enabled, the keys play Track 1 (Bass) when Part A is selected (Shift + Fader Button 6):

Likewise, the keys play Track 2 (Pad) when Part B is selected (Shift + Fader Button 7):

Split (Shift + Fader Button 8) splits the keys between Part A and Part B, mimicking two separate keyboards - this is useful for playing two different instruments at the same time, mimicking the use of two separate keyboards.

Holding down Shift + Fader Button 8 (Split) lets you change the first note of Part B (Split Point, C3 by default) - the screen shows “Select Split Point” and pressing a key on the keyboard assigns it as the Split Point.​

You can latch Shift by double-pressing the Shift button.

In the project template, when both tracks are record-enabled, with C3 set as the Split Point, the keys below the Split Point play Track 1 (Bass):

The Split Point and above keys play Track 2 (Pad):

Layer (Shift + Fader Button 9) lets you stack Part A and B together so that both Parts will play simultaneously when pressing the keys - this is useful for layering two different instruments together.

In the project template, the keys will play both Track 1 (Bass) and Track 2 (Pad) at the same time, as long as both tracks are record-enabled:
