OK, first off, want to say congrats to you helgoboss, your software kicks butt man !
Want to also thank you for the comparison spreadsheet, although I should put some more effort into keeping it up to date -- like you, I'm the only coder, busily working on CSI
Not to hijack the thread, but to sensapaz, if neither ReaLearn or OSC is what you are looking for, might I suggest CSI.
A lot of users use CSI and TouchOSC, including me
It takes a bit of work to set up, but might be worth a look.
Not saying it is what you are looking for, just want to provide another possible alternative.
