It is really easy to change behaviour of button in prime.

First, to allow usage of qml file instead and remap , rename file KnownDevices.vfsb to something else

cd /usr/Engine/Content
mv KnownDevices.vfsb KnownDevices.bsfv 

When doing this, we tell prime to use qml files located in /usr/Engine/AssignmentFiles/PresetAssignmentFiles/<product code>/ So on prime go it is JP11.

There are two important file, assignment file & device file. These 2 files mus have the name of the midi sound card of the device.

Here is what we have on PGo :

# amidi -l
Dir Device    Name
IO  hw:0,0,0  PRIME GO Control Surface

So QML files must have the same name.

# ls -l
total 56
-rw-r--r--    1 root     root          4463 Jul 10 22:14 PRIME_GO_Control_Surface_Assignments.qml
-rw-r--r--    1 root     root          3091 May 28 04:49 PRIME_GO_Control_Surface_Device.qml

If you omit these 2 files, Mapping is not working so buttons dont work.

We can found templates for each board in each product_code subfolder.

So for Prime Go, by default the QML file has not the name “PRIME_GO_Control_Surface_Device.qml”, its something else , so just rename your files with mv to have this name.

to add Slicer juste change these lines :

			PerformanceModes {
				ledType: LedType.RGB
				modesModel: ListModel {
					ListElement {
						note: 11
						view: 'CUES'
						
					}
					ListElement {
						note: 12
						view: 'LOOPS'
						altView: 'AUTO'
						shiftView: 'SLICER'
					}
					ListElement {
						note: 13
						view: 'ROLL'
						altView: 'SAMPLER'
						shiftView: 'FIXED'
					}
				}
			}

We add SLICER & FIXED on shift + functions ( shift loop & shift roll to get in slice mode )
