Matrix pattern sequencer in Reason

Published: 2016-10-12

Welcome back to another reason tutorial. I have been writing down multiple articles where the Matrix Pattern Sequencer has been applied. I never wrote down a complete article dedicated to this simple, yet effective machine. Since the Matrix is quite versatile as a device. What makes it even cooler is that matrix has been here since the first versions of Reason. Till this day, the pattern step sequencer still is quite useful.

By default the Matrix pattern step sequencer is used to make monophonic lines. The matrix gets connected to an instrument in this case. To use the matrix in this context follow the following steps:

- Create an instrument
- Create a matrix pattern step sequencer

In this set up the matrix will automatically connect to the device. Where the gate CV gets connected to the Gate input of the instrument. The Note CV gets connected to the Note CV input of the instrument.

While using the Pattern banks (1 till 8, ranging from A till D). By default the matrix can hold up to 32 patterns. To make use of the Matrix pattern bank make sure to create a Pattern Lane on the Sequencer window. Select the Matrix pattern step sequencer on the sequencer window. Right click it and select "Create Pattern / Loop lane"

At this point the sequencer window can be used to trigger patterns from the Matrix Pattern step sequencer. Since this is method is pretty old school (Rebirth anyone?), it still has its useful application:

- creating monophonic bass lines
- prototypic monophonic leads

Creative Matrix Revolution

While this is all in its default state, there are some creative applications while using the Matrix. By default it will use the pattern / note segment. There is a knob on the Matrix that can switch between Keys and Curves. Curves are by default not used, since it requires a manual connection.

Matrix Pattern from Keys to Curve

While setting the knob to Curve the left panel will not display note information but display curve information instead.

Matrix Pattern Step Sequencer Curve

This is where the Matrix pattern step sequencer will shine. Since in this stage the device can be used to automate different settings inside the reason rack while using pre-programmed patterns instead. In most cases an LFO pattern (low frequency oscillator) will be enough to make these pattern based automation changes. But sometime there is need to have a different pattern, or a custom pattern instead.

The only thing that is required is sending the Curve output (rear of the Matrix) and connect this to any setting that needs to be changed).

Matrix Pattern Step sequencer Curve

For instance, in this case I am using the Curve to make changes with in the Index of a Malstrom. This makes the sound differ every note that is being triggered.

But since the curve can be applied to any CV input there are endless possibilities in this realm.

Using the Matrix as a Learning Control Voltage Kit

A different side aspect of this would be using the Matrix Pattern step sequencer to learn the basic usage on what makes Control voltage tick. In this case I often use the same method to make it visual:

- Create a combinator
- Create a digital delay line inside the combinator
- Set the steps of the digital delay to Milliseconds
- Create a Matrix pattern step sequencer (while pressing and holding shift, so no there is no auto routing taking place)
- Set the Matrix Mode to Curve
- Connect the curve from the matrix pattern step sequencer to the rotary 1 input of the combinator

Control Voltage toolbox
- Press show programmer on the combinator
- Select the digital delay line in the programmer window
- select Source: Rotary 1, Target: Delay time Ms, Min: 0, Max: 2000

Control Voltage toolbox

And our tool box is complete. At this point there will be no sound what so ever. However if there are any changes inside the curve it will show a digit in the digital delay line to show us what kind of changes that are being made. Thus this may help you understand how to handle Control Voltage in more detail.

Unipolar VS Bipolar

Just one last bit before closing this article, there is a setting that might require a mention and that is the Unipolar / Bipolar switch on the rear of the Matrix.

Unipolar vs Bipolar

Unipolar means that is sends out only positive values ranging from 0 till 127.
Bipolar means that it sends out positive and negative values ranging from -64 till 63.

To answer the question that I often see, why is there a negative value from -64 and a positive value of 63?
Answer: this is because it uses a 7bit signature.The minimum value is 0, where the maximum value is 127. The number 0 is a value. So it can hold only 128 different numbers. Thus it ranges from -64 to -1 (64 numbers) and from 0 to 63 (64 numbers). Equals a total of 128 numbers.

I hopes this makes sense.

Anyway, there are some create set ups you can create using the Matrix Pattern step sequencer. Let me know in the comment segment what kind of set ups you find useful. Also if you have any questions or criticism regarding this article then please write to us. I listen from time to time ;)
