Grubo

Grubo is an experimental project that aims to present an audio-visual experience using Roland Groovebox MC-101 and the Unity game engine.

System requirements

Unity 2019.3
HDRP compatible desktop system

How to use

Grubo uses a MIDI connection to control visual effects from MC-101. You can use a physical MIDI connection (MIDI interface + MIDI cable) or a USB cable connection with the MC-101 MIDI driver (only available for Windows and macOS).

You have to enable MIDI message transmission (TxUSB MIDI/TxMIDI Out) on all four tracks. These options are available from the track settings menu (press SHIFT and TRACK SEL 1 - 4). Please see the reference manual for details.

The visualizer is designed under the assumption that each track is assigned as follows:

Track	Type	Visual Effects
Track 1	Drums 1	Structure effects
Track 2	Drums 2	Camera effects
Track 3	Synth 1	Ribbons 1
Track 4	Synth 2	Ribbons 2

There are a few key controls. All the visual effects are disabled by default, so at least you have to enable one of these effects by pressing 1 - 5.

Key	Function
1	Toggle track 1 effects
2	Toggle track 2 primary effects
3	Toggle track 3 effects
4	Toggle track 4 effects
5	Toggle track 2 secondary effects
q	Color scheme 1
w	Color scheme 2
e	Color scheme 3
r	Color scheme 4
t	Randomize color scheme
a	Toggle hue shifter
z	Toggle invertion effect
