Awesome Korg Volca & logue

Use the Korg KA‑350 or a supply explicitly listed as Volca-compatible: 9V DC, enough current (≈600mA+), with the Korg/EIAJ‑03 barrel plug. The catch is that a Volca's plug size and polarity generally do not match a typical guitar-pedal supply — the wrong plug, polarity, or insufficient current will fail to power it or cause noise. Don't assume your pedalboard wart fits; confirm the spec against Korg's KA‑350 before plugging in.

Yes — the Volca's line output works into pedals, though it's line-level so a drive/reverb pedal may behave differently than with a guitar; a small gain/buffer helps. Stereo-image and noise vary by pedal. It's a popular way to thicken the Volca Drum/Bass.

Pajen's community firmware unlocks features the stock firmware hides — e.g. polyphony and extra parameters on the Volca FM, and tweaks on the Sample. It's widely used and reversible (you can reflash stock), but flashing is at your own risk: follow the guide, use a clean audio path, and back up first.

Use Korg's Sample Librarian app (or the audio-transfer method) to send WAVs to the unit over the headphone/line connection from a phone/computer — it's an audio-data transfer, not a USB drive. Keep samples short; the Volca Sample has limited memory and sample slots.

Use the Sync In/Out (3.5mm) for analog pulse sync between Volcas and compatible gear (Pocket Operators, Pocket Operators, etc.), or MIDI In for clock/notes from a sequencer. For a DAW, send sync via a MIDI-to-sync interface or a device that outputs the pulse. Mixing MIDI clock and analog sync requires a converter.
