Guide/tutorial for patch request button?

nevermind, you are correct, it is always parameterNumber. I’ll delete my previous posts so people dont get confused

yes, it is a parameterNumber. The reason why the type is required is the fact that there are synths that use the same parameterNumber in combination with different message type. Thus type-parameterNumber allows you to address the particular instance. I do recall that eg Novation Circuit has cc7 and nrpn parameter ranges overlapping.

I’ve been able to follow this and get it working on the TX81Z. See here.
