Quantize issues in DP 4.6

[abe_lincoln78]

So, at the urging of a friend who is quite annoyed by my purist ways I decided to try to tighten up one of my tunes using the Quantizing abilities of DP. The Quantize option works awesomely for aligning my bass part to the drums, but I get this hideous artifact that occurs sporadically during the sustains and sometimes at the end of notes. If this is the way the tool works I will never be able to actually use it.

The manual talks about quantizing as if it is a real time effect applied during playback. Is this true? I feel that it might explain why my track sounds so horrible after quantizing. Otherwise, what gives?

I have tried changing the sensitivity of the beat detection engine and so on. I have also gone through and deleted all false beats and beats that are located on the release. I assumed that DP would execute a smooth time stretch between each of the attacks this way, but it still did the same thing.

Any advise on how to make this work would help greatly.

Hi

Would it help if you use Fade ins/outs and Crossfades after you Quantize those Sound Bites?

I quantized with no fade ins or outs.

Ok, so I think I have a more detailed description of what this contraption is doing. I'm fairly consistent with my bass playing so really DP just shifts most of the track a little to the right, but there are some beats that it thought needed to be pulled earlier in the sequence. It appears that any time there is a time stretch in the quantize it is misdone. I would characterize what I'm hearing as jitter. Its really very strange.

I decided to try this in a different track as I figured maybe the issue was that a 44.1 khz file couldn't be time stretched, but even with the 88.2khz file the result of the quantize was bad. Here is an example of a guitar track before and after quantize. The arttifacts are very clear and abundant here. Let me know what you think.

P.S. - I downloaded the trial version of Ableton Live and tried quantizing inside that app with the same problem. Am I doing something wrong?

You will get better results if you add Effects after quantizing.

This one has also good info:

The sample I gave you had ABSOLUTELY no effects on the track itself. If there is reverb in the track its from a send not an insert.
