Multi-Dimensional MIDI/OSC/CopperLan Expression Through Hand Gestures

Please contact us through the product website if you need assistance with using GECO. We’ll get back to you as quickly as possible. Additionally, on the website you’ll find an extensive collection of video tutorials to help you get started and a user forum to exchange tips and tricks.

GECO is one of the easiest and most powerful solutions to interact with MIDI/OSC/CopperLan through touchless control. Our custom multi-staged processing engine ensures an extremely low processing overhead and near zero latency, while still providing you with beautiful real-time visual feedback and powerful customization capabilities. GECO has been designed for live performance and quick configuration during rehearsal by industry professionals that have years of experience with high-speed low-latency electronic music software.

GECO doesn’t produce or manipulate sound directly, its purpose is to control other software or hardware that understands MIDI, OSC or CopperLan.
