Make beats anywhere with Pulsar-ES, an authentic preset drum machine expanded into a mobile groovebox for iPhone and iPad. Inspired by the rare Soviet/Ukrainian PULSAR hardware, Pulsar-ES keeps the original industrial rhythm-box character while adding the missing modern features producers expect: MIDI editing, deeper FX, Ableton Link sync, AUv3 workflow, and mobile project control. Play ideas fast on the 4x2 drum pad grid, then turn them into full patterns with the MIDI Clip Editor. Draw, move, and resize notes directly on the grid so your rhythm stays editable after the first take. Shape your sound with a hands-on FX rack built for quick decisions: - Filter with low-pass, band-pass, high-pass, and notch modes - Reverb with room, hall, and plate spaces - Overdrive with overdrive, distortion, fuzz, and tube modes - Delay with digital, tape, and ping-pong modes - Chorus and compressor for extra movement and control Pulsar-ES also supports Ableton Link sync, project save/load, rhythm presets, and a portrait layout designed for making music on the go. Start a beat, edit every note, shape it with FX, and keep your ideas moving.
