Re: quantizing intelligently

I use heuristic quantizer after recording a playing session. My problem is I'm not good at keeping machine-perfect tempi. (Well, I don't think any human can be as precise as MIDI). So it usually needs a lot of tweaking. I usually add a new track below the recorded track and manually put new notes in the right places on the new track.

When focussed on putting notes into a score, I manually put notes on the score using the mouse pointer.

I don't think either quantizer does a good job for scores. Especially if there's more than one melody on a track. Example, 4-part harmony, RG has a propensity for misaliging notes of different durations, like 1/8, 1/4, 1/2. If I have a held half note in the bass and other voices have 1/8 notes, I have to turn the half note into 1/8 notes and tie them together to get melodies aligned right on the score. This happens even if I do them each on a seperate track, then merge tracks together into a single staff.
