That is their DAW application, but I do not use it. For audio separation, get the other program they sell called Deep Remix or something which we have for Mac on Sister Site. People mostly just call it RipX anyway. It works great for me because it processes locally, just a little slowly.
There are plenty of other stem separation options like UVR.

Once you get files separated out into audio, you can still do a little cleaning of the audio prior to converting it to Midi. I like to use a transient designer to shorten tails between hits, especially hi-hats and other short fast percussive or staccato elements. If you still end up with a bunch of data fragments in the midi, you can add an arpeggiator plugin and crank up the speed before bouncing it in place again and the audio to midi convert will do a better job. There is also NoteGrabber, and a bunch of other options. Many of them are free.

I've had this Max for Live device for a while now but never really tried it so I forgot about it. I think it was made for live drum triggering, but it works for recordings too apparently!

 

It had been a while since I used it, but I loaded up UVI Drum Replacer for other purposes, but it jogged my memory to see the record button on the plugin interface. It records midi data, kind of like how you transfer DAW playback into Autotune or Melodyne.
Once it is done recording, you just drag out the midi file to a daw instrument channel. Usually I would use it as a sort of threshold-based layering tool, like Snapback. The only downside to it, is that you have to transfer the drums' audio to the plugin in realtime.
