| Hey buddy.
Sounds like a case of snap to grid.
Snap for protools refers to your regions or midi being constrained to the grid or tempo of your choice.
If you move an audio region in grid mode that is set to 1 sec or 1 beat you can only move the region in these increments as it will snap to this value.
You can also set how the midi note snap (constrain to s specified value) as they are played in.
Quantise has to do with midi.
Quantise is how the midi notes are arranged after you have played them.
If you set input quantize and play an arrangement that is somewhat out of time or sync to the beat input quantize will slightly rearrange the notes so that they are perfectly in time. This can seem mechanical thats why DAWs give you the option of specifying the % amount the input quantise value will be altered.
Quantize is similar to snapping individual midi notes to a grid.
Groove quantize give you the ability to alter pre arranged midi performances.
Say you have a drum beat that sounds a bit stale, dial up a the groove quantise and choose the type of groove quantise be it swing or what ever and then select the % strength of quantise and wala no more staleness thanks to groove quantise.
For more info read chapter 23 of the PT reference guide.
Hope that helps.
Its a bit confusing i admit and i hope i did ok at the explanation. |
