Total respect for those of you who draw midi by hand and make it work. I'm not sure I'd have that type of patience, I'll stick with my Yamaha keyboard and Akai MPD232.
I enter all my midi in ASCII on a Tandy TRS-80 and then port it to the VI with the cassette tape interface.
No, wait. I used to do that, but I've since thrown concrete blocks at all my old gear.
I'm not a keyboard player, but even with 'club hand' I can get some note-on velocities that make the phrase more musical. And I'm not above using step record when I have a lot of data to enter. Gotta be way faster than typing dots. And my keyboard also doubles as a MIDI controller, with those pitch, modulation, and CC thingys. I try mousing CC data, but that's a real drag (pun intended!).
I wager a few sessions (or weeks of sessions) with a keyboard controller and you'd be much faster - and happier with your product. It's another tool to use. Why hang picture frames with a wrench?
