The step sequencer is designed for ease of editing and allows 10 individual parts to be inserted or removed on the fly. Sixteen-step keys enter notes while maintaining visual confirmation of the timing of the notes in a measure. A performance can be recorded in real time. Up to 16 of the sequence patterns created can be stored in internal memory. The pattern chaining affords full song creation.

The motion sequence function records any time-varying changes made to the sound using the knob movements. An active step function allows for skipping steps during the sequence, and the step jump function instantly plays just the key-pressed step. A swing function adjusts the swing playback position, generating the distinctive groove of dance music styles. Get off the grid with Start Delay, which creates swings and grooves by delaying parts to deviate from 16 quantized steps.

A frequency isolator applies changes to the sound by boosting or cutting the low/high ranges with the isolator implemented as an analog circuit. The built-in reverb effect can be switched on/off for each part, and it is possible to save up to six song patterns, each combining up to sixteen sequences. Additional samples can be recorded and loaded using the Volca sample's dedicated AudioPocket App over USB (the internal sounds are overwritten).
