Quantizing recorded MIDI

Elementary question as usual, but not easily solvable after the usual searches.

In a new Dorico project, I recorded some MIDI into four tracks. The notation that Dorico rendered was accurate. However, when hitting play, it played my “natural” unquantized playing, and I found it too messy.

So while I want to keep the visual notation, I wanted to quantize the MIDI.

I can’t figure out how to do that. I found the process for requantizing notes (Requantizing notes) which I believe is what I want. However two problems: (1) the documentation says I can do this in Write or Play mode, but when I try it in Play mode, I can’t figure out how to select the MIDI at all, and (2) when I do it in Write mode, I can indeed select all the notes, hit Requantize, quantize them hard to the 16th note, but when I go to play back my score, it’s still not quantized.

What did I do wrong?

I also checked Quantization Options (https://steinberg.help/dorico_pro/v4/en/dorico/topics/project_file_handling/project_file_handling_midi_quantize_options_dialog_r.html) but that doesn’t appear to have any on/off switch for quantization, so I don’t know how to use it.

One potential clue: take a look at the screenshot below. In the upper area, it looks like all the notes are tightly quantized. However, look at the downbeat of m2 (green wiper), where the pink bar shows “natural” - see how that is clearly before the bar line? That’s what I hear. But I can’t figure out how to fix this. (I also don’t know what that “natural” bar is for at all, as I don’t know what it is so I don’t know how to look it up in the documentation.)

I may be wrong, but I think you need Play>Reset Playback Overrides

I just tried this, and it doesn’t do anything to cure my problem. (Playback is still unquantized.)

Also note for the Dorico team: there doesn’t appear to be any documentation on Janus’s suggestion of Reset Playback Overrides. When I searched the Dorico help for it, all I found was this page (Inputting notes using MIDI recording) which mentions it but does not explain it nor link to anything further.

Just tried it, and it works for me. Record your (bad) midi. Requantise to what it should be. Hit play and it still plays your bad midi. Select the passage and reset overrides. Hit play and it plays what is notated.

(edit: I agree the term reset playback overrides is unhelpful)

Woah. It definitely didn’t work the first time, but after Dorico crashed and I had to relaunch it, I tried it again, and now it worked! Thanks for the help.

Agree: it’s not a descriptive command, and it begs the question of what “requantize” is, if it’s not this.

Requantizing affects the notated rhythms, not the rhythms that are played back. This is described in the manual here: Requantizing notes

At the bottom of the manual page Inputting notes using MIDI recording

  • If the notes you played in are not notated as you intended, you can requantize them.
  • If you do not want to retain played durations for playback, you can reset playback overrides.

Thanks for all this. Makes sense now but it did not make sense at first (plus, Dorico got itself into a funk and was malfunctioning, so when @janus tipped me off to Reset Playback Overrides, it didn’t work at all).

The “Requantize” function is influenced by the “Program settings/Playback/Keep note positions”. Temporarily deactivate this option, otherwise the original recording with the corresponding deviations will be used again with each new quantization.

In Dorico 4.3 I have found the above to be incorrect. That setting does not affect Requantize, as far as I can tell.

I still have this useful behavior unchanged in Dorico 4.3.

Did anyone find out how to do this? Surely there’s a quantize button somwhere.

Try entering quantize or requantize

Or: Edit/requantize
