Khoreo is an audiovisual project with the Unity game engine and the Roland MC-101 synthesizer.
YouTube video - 20 minute performance at Channel #22
- Unity 2023.1
- Roland MC-101
- UVC compliant video input device (webcam)
Khoreo 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.
You must enable the MIDI message transmission (TxUSB MIDI/TxMIDI Out) on
all the 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.
I designed the visual effects under the assumption that each track is assigned as follows:
| Track | Type | Effects |
|---|---|---|
| Track 1 | Drums 1 | Camera |
| Track 2 | Drums 2 | Light |
| Track 3 | Keys | Hair |
| Track 4 | Pads | Others |
Each effect is only enabled when its assigned audio track is active (not silent). In other words, you can instantly deactivate the effects by cutting the track off using the fader.
There are a few key controls that modify the effect parameters.
| Key | Function |
|---|---|
| 1 | Main spotlight |
| 2 | Posterize effect |
| Q | Change hair length |
| A | Body trails |
| S | Web-like string |
| Z | Swirling lines |
| X | Beanstalk thing |
