This robust input device for music production and live performance packs not one but four fully configurable and independent sequencers, with LFOs, loopers, arpeggiators, and more. Each supports up to 128 steps, with auto-harmonization capabilities. It connects via MIDI, CV, or Bluetooth.
Teenage Engineering’s OP-Z combines a synth and sequencer in a minimal device. It can record 8 audio tracks and 8 control tracks at once, and has a 2-octave keyboard, speaker, microphone, headphone jack, and USB-C/MIDI ports built in. It also works wirelessly with iOS.
