EP-133 K.O. II
Teenage Engineering · 2024
The iconic calculator-shape sampler-sequencer. 128 MB sample memory, 12 velocity-sensitive pads, dedicated fader + jog wheel, swing, fades, punch-in effects, dirty preamp, built-in mic. Lockable workflow that forces you to commit. The portable groovebox you actually finish songs on.

label your pads
Name what's on each pad so future-you knows "kick", "snare", "skit", "talkbox," not "C2, C#2, D2." Eventually drag .wav files in and transfer to the EP-133 K.O. II via the sample tool above — for now this is your label sheet.
