From usual drum hits like kicks, toms, snares, claps, hi-hats and cymbals to unusual and complex sounds like drones and weird modulated creations. The provided MIDI implementation lets the 01/IV be triggered via MIDI, which makes it a powerful piece of equipment in a setup.

−

The concept of 01/IV is unique as it has four identical voice channels with all the power of synthesizing various type of drum sounds. Any channel can play a kick, a cymbal, toms and congas, or even a bassline. Channels can even be combined, can modulate each others in pairs (FM) or can be layered to form complex sounds. All these achieved with a flexible routing system composed of slide switches and carefully calibrated synthesizer elements.

01/IV inherited genes from legendary drum machines and drum synthesizers like the Pollard Syndrum, the Roland 808 & 909, and Pearl Syncussion SY-1. It has a true analog audio path, but also added a very flexible digital modulation system of a multi-function LFO, ramp and retrigger generator.
