“They can’t,” is a statement limited to constraints imposed by the hardware or the operating system. The coding skills? That’s silly. The team’s plenty talented and could pretty quickly learn to do something if they want to. The Renoise framework? That may be so currently, but it underwent a huge overhaul for R3, so it’s pretty obvious that Renoise’s capabilities are carved in stone. This is a feature that’s definitely possible, and your conclusion is poorly drawn. Just because a feature has been requested but not implemented does not mean it’s impossible. If it’s not implemented, it’s because:
a ) They haven’t thought about it.
b ) They don’t want to implement it for one reason or another (doesn’t fit workflow, huge overhead, can be achieved in other ways).
c ) They don’t want to implement it yet, because they’d rather put efforts elsewhere.
Maybe I’m being a bit pedantic, but this is a little akin to saying, “I can’t buy a castle.” You can buy a castle. You may have to save for a dozen years (which you might not see as being worth it), but you can certainly buy a castle.
I already have a virtual MIDI cable solution, and have thus already been playing with this. (It’s awesome.) Bidule’s pretty cool, but far more than I need for a simple task. Thanks, though.
