Not sure what the issue is with TransMIDIfier, but i use it as it’s one of the most simple utilities out there. Perhaps you’re forwarding the wrong ports, or they’re still selected in the MIDI setup of Cubase (Under ‘All’) and thus still making it through to the track?
As for the mappings, go only by what i’ve drawn out, or other Cubase mappings - as you’re confusing yourself with Logic Pro mappings from that link. Cubase has a unique system for MCU hardware which i’ve never seen before and they don’t use the standard button layouts. It’s really their own take on things.
Also, don’t try and assign anything to quick controls etc. as that’s not how it works, it operates entirely using the MCU remote protocol and the remote editor for parameter mappings, when you see it running it works really well. however.
As i owned MCU hardware for many years it’s made it so much easier for me to make sense of, perhaps. As i can imagine which hardware controls i want emulated via the Maschine controllers.
Most importantly, which i’ve missed and presumed you knew of already is the MCU section in the official docs, this is really key if you haven’t already.
You can see on page 7 how their mapping compares to an actual MCU default hardware (Just google image search a hardware panel to see).
So, to get you on the right track - the absolute easiest way for you to get instrument mapping running is to follow this example:-
Create a shortcut key to instrument mode (Orange), which will map to MCU parameter ID 80 (As seen on the chart i made).
When in that mode you’ll be faced with page 41-42 from the above Remote Control Devices.pdf manual.
You then have channel left and right buttons mapped on your Maschine (Circled green) to navigate the pages, and use the vpots to control each parameter. Hopefully that should get you to the point where things start to tick.
Likewise the inserts mode work the same, except you can roll Vpot 1 to select the insert to control and then channel bank across the pages of each insert.
If you load my mapping (.zip) file into a Maschine Mk2 selection on your (NI) Controller Editor software, it may give you a few ideas on how I have mine laid out. But i don’t know how much sense it will make to you at this point lol.
If you fancy doing a screenshare or something so i can help you better, just throw me a message, more than happy to.
