Using Pattern Devices

Programming a Pattern

The actual programming procedure differs for the different devices (see the

electronic documentation for descriptions of the Redrum and Matrix, respec-

tively).

However, some basic principles are common for all pattern devices:

Steps

Patterns consist of a number of discrete steps. For each step, you can enter a

note, a CV value or various properties, depending on the device. When you run

the pattern, each step will be played back in turn and will play a sound or send

out the information programmed for this step. If you have ever used a drum ma-

chine, this will be obvious to you.

Pattern Length

For each pattern, you can specify a length, i.e. how many steps it should contain.

The maximum pattern length is different for different devices.

Pattern Resolution

The pattern resolution determines the length (note value) of the steps. When the

pattern resolution is set to 1/16, each pattern step will be a sixteenth note, when

set to 1/8, each step will be an eighth note, etc.

The Resolution control on the Matrix. As with the pattern length value, you can program

different resolution settings for different patterns.

If you change the resolution of an existing pattern, the audible effect will be a

change of pattern playback speed. This may seem strange at first, but if you

think about it, it’s logical:

Let’s say you have a 16 step pattern with resolution set to 1/16. The length of

each pattern step is then one sixteenth note, and the whole pattern plays back

over a whole 4/4 bar (16 sixteenth notes = one whole bar).

Now, if you change the resolution to 1/32, each step will be a 1/32 note - half its

original length. There are still sixteen steps. This means that the whole pattern

plays back over half a bar (16 * 1/32 = 1/2). In other words, the pattern plays

back at double speed.

Pattern Shuffle

Shuffle is a rhythmic feature, that gives the music a more or less pronounced

swing feel. It works by delaying all sixteenth notes that fall in between the eighth

notes.

In Reason, you can activate or deactivate shuffle individually for each pattern in a

pattern device. However, the amount of shuffle is set globally with the Pattern

Shuffle control on the transport panel.
