“If you're looking to enter the world of synthesis, sample-triggering or MIDI sequencing using your guitar or bass, then the Roland GI-20 GK-MIDI Interface is your box. The GI-20 detects the signal from any electric guitar or bass equipped with a GK-3 (see item #700379) or GK-3B (see item #700373) pickup, respectively, and lets you trigger synthesizers and samplers, or even record your playing as MIDI data. And with its built-in USB MIDI port, the GI-20 is perfect for computer-based recording setups.
