I'm Keyboard free, despite my first purchase 20 years ago being a BassStation Keyboard, I never got on with Keyboards. Picking up my fathers flute about 12 years ago, changed things, so now I have a Midi Wind Controller (WX5) that I am please is in a parcel on the way from Wales to Vietnam as I type. I also have a Korg nanopad2 for percussion, it's not perfect, but I like it.
My bug bear with Melodyne, is needing the full studio version to get pitch bend/vibrato data in a Midi transfer, I've mentioned this too much on this forum, but it relevant here. Why, do we still need Midi Controllers, because you are more connected to what you play, when you play it in real-time.
