I haven't been using Studio One the past few months, because I've been working on a bigger project. But here are some things I remember irritating me: The piano roll randomly resizes the zoom when moving about. When it does, it often forgets the saved zoom setting. The CC lanes that are visible change, again seemingly at random. It takes a lot of clicks to open anything other than the default lanes and I've never found a good way to create my own defaults. You can't open two piano roll windows at the same time; or if you can I haven't been able to figure out how to do it. (I do like the flexibility of the piano roll design Studio One has though, which allows easy navigation and overlay of many parts.) It has no articulation support. Because Studio One works best with multi-timbral output, you have to manually locate the instrument in the instance of Kontakt that houses it if you need to see the GUI. I also have persistent problems with Studio One failing on start up and crashing on close. Its manual is completely deficient.That's very diffuse. Could you please be a bit more concrete and give examples? What exactly do you miss and what exactly is not so good when it comes to MIDI editing?
That said, I like Studio One, and use it on my smaller projects. The sketch pad is a marvel that I wish other DAWs would emulate. I very much prefer the way its arranger works for moving around sections compared to the way, say, Logic does it.
