Groove

In the early days of sequencers, many people thought that electronic music sounded

mechanical or sterile. This impression (which, at the time, might have been a fair

observation) was based on the fact that sequencers could only output notes that were

quantized. This is no longer the case. Logic’s resolution is so high that at a tempo of 120

it can differentiate between two notes that are just 520 microseconds apart. This is

equivalent to a single oscillation cycle of the highest note that you can play on a

soprano saxophone.

It is, of course, still possible to generate sterile, mechanical timing, if that’s what you

actually want (although even straight quantization can be given a groove with the aid

of the Q-Swing parameter), with the quantization functions (see “Quantization” on

page 147).

Logic also allows you to use your own quantization grid (or Groove Template), making

full use of the system’s high timing resolution.

Creating Groove Templates

Rather than quantizing the notes to one of the preset grids, you can create new ones

based on the rhythms of other MIDI Regions. These are referred to as “groove

templates”. Groove templates make it possible to capture the small timing deviations

which give a MIDI Region its “feel”, and apply them to other MIDI Regions.

Creating Your Own Quantization Template (Groove)

The Options > Groove Templates > Make Groove Template function transforms the exact

timing of notes in the selected MIDI Region into a quantization template. It then

appears in the pull-down menu of the Qua parameter (in the Region Parameter box),

named after the MIDI Region on which it is based. It can be used on any other MIDI

Region, in exactly the same way as the other items in the Quantize pull-down menu.

In general, two-bar MIDI Regions work particularly well as models for this function, but

you can use MIDI Regions of any length. Make sure that the model MIDI Region

actually contains a note at every desired quantization value.

Deleting a Quantization Template

Use Options > Groove Templates > Remove Groove Template from List to delete the

selected model MIDI Region from the list of possible quantization templates. The next

time you open the pull-down menu, this quantization template will no longer be

available.
