RED – automation (VIDEO)


This video demonstrates automation on the Groovesizer RED. Record the movements of Pot 1 whilst holding Shift. It corresponds to Grain 1 Pitch on the internal synth. The recorded automation can also be sent out as MIDI cc data on one of 16 preset cc numbers (selected in Preferences Mode). The presets correspond to the 16 cc numbers that the Korg Volca Keys responds to (for more details, please consult the manual). In the video, the automation controls filter cutoff on the Volca Keys (cc44 – RED’s default).

Groovesizer RED – bank modes (VIDEO)

This video demonstrates the 4 modes for the Groovesizer RED’s user banks.

The Groovesizer RED’s 32 user locations are arranged in 8 banks of 4 patterns. There are 4 different modes for each bank:
Mode 1Loop 1: each pattern is looped.
Mode 2Loop 2: triggering pattern 1 loops patterns 1 and 2, triggering pattern 3 loops patterns 3 and 4
Mode 3Loop 4: triggering pattern 1 loops pattern 1, 2, 3 and 4
Mode 4Random: the next pattern is selected at random (1, 2, 3 or 4)

Groovesizer RED – play modes (VIDEO)

Here’s a video showing off the play modes of the Groovesizer RED – if all goes to plan we’ll be releasing the RED in the coming week. The kit will be priced at US$80 – postage included.

The Groovesizer RED is a DIY 16-step sequencer and granular synth. It’s based on the original Groovesizer mk1 Arduino project. It features 16 LEDs (one per step), 5 potentiometers, and 5 buttons, MIDI input and ouput on 5-pin DINs, MIDI sync in and out, and audio out (mono) on an 1/8″ jack. There are 32 user locations for saving patterns and patches. Up to 4 patterns can be chained together to create a 4 bar pattern. Note entry can be quantized to one of 12 pre-defined scales. Patterns can be triggered and transposed via MIDI. Notes can also be entered via an attached MIDI keyboard.
