forScore MIDI parameters

[frozzers]

I've had a good look round the forum and the forScore website but I can't seem to find any instructions on how to set up a PDF in forScore to receive the required MIDI commands from a Tyros (5) registration to select a forScore PDF on my iPadPro.

I've followed Fred Smith's excellent video on this process using Songbook and I've managed to get it working through the lite version of Songbook but, when I try to do the same in forScore, on the PDF edit function, the options to choose the MSB, LSB and PC MIDI parameters are different to those in Songbook.

Does anyone know how I can set up the MIDI parameters in forScore?

I could upgrade Songbook but a) it's quite expensive and I've already paid for forScore and b) I really like forScore's Dropbox integration as opposed to having to rely on iTunes.
