MATRIX PATTERN SEQUENCER

About Unipolar and Bipolar Curves

On the back panel of the Matrix you will find a switch, allowing you to select

between “Unipolar” or “Bipolar” Curves. The difference is as follows:

➜ A unipolar curve has values starting from “0” and up.

“0” is the value produced by all steps when they are “empty” (not visible).

Unipolar is the default setting of this switch when a new Matrix is created.

Unipolar curve.

➜ A bipolar curve is divided in the “middle”, with the middle repre-

senting a value of “0”.

The curve reflects this. If no curve has been drawn and you switch to bi-

polar mode, all steps go from the bottom up to the middle of the scale

printed to the left of the pattern window. Thus, all steps are at “0”, and the

curve can be drawn both up and down from the middle.

Bipolar curve.

Bipolar curves are essential in some instances. If you want to use the Matrix

to CV control the Pan parameter for a mixer channel for example, a unipolar

curve would start at zero - which for Pan equals center position. This means

that you would only be able to use the curve to pan in one direction from this

center position. A bipolar curve however, will have the zero value in the mid-

dle, allowing you to draw pan curves in both directions. Bipolar curves can

also be used for controlling parameters with positive and negative values.

Setting Pattern Length

You may want to make settings for Pattern length, i.e the number of steps the

pattern should play before repeating:

➜ The “Steps” spin controls are used to set the number of steps you

wish the pattern to play.

The range is 1 to 32. You can always extend the number of steps at a

later stage, as this will merely add empty steps at the end of the original

pattern. You could also make it shorter, but that would (obviously) mean

that the steps you remove won’t play back. The steps you remove aren’t

erased though, if you set the step number back again, anything recorded

in the previously removed step locations will be played back.

Using Tied Notes

If you activate “Tie” to the left of the Gate pattern window, you can create

longer notes (eighth notes, quarter notes etc). A quick way to draw tied gates

is to hold down [Shift] when you input the gate values.

Entering tied gate values.

➜ Each step that has one tied gate value will be twice the length com-

pared to a normal step.

Tied gate steps are indicated by being twice as wide in the pattern win-

dow.

➜ If two or more notes of the same pitch are tied together, the result

will be even longer notes.

Tied notes are also essential if you want to create typical TB-303 “Acid”-type

lead lines - see page 152.

Selecting Patterns and Pattern Banks

This is described in the chapter “Programming Pattern Devices” in the Basics

book.
