@JimmyJ well this seems to be the relevant bit:

Rec 1 C-1 Dec: 0, hex: 0
Rec 2 C#-1 Dec: 1, hex: 1
Rec 3 D-1 Dec: 2, hex: 2
Rec 4 D#-1 Dec: 3, hex: 3
Rec 5 E-1 Dec: 4, hex: 4
Rec 6 F-1 Dec: 5, hex: 5
Rec 7 F#-1 Dec: 6, hex: 6
Rec 8 G-1 Dec: 7, hex: 7

so there are 8 record commands, all on channel 1, with velocity 127 = on 0 = 0ff

So this (if this is correct) would be trivial in HISE...
