Timbral Parts1 Part

The Arturia MicroFreak is a dynamic hybrid synthesizer combining digital oscillators (with 18+ modes including Karplus-Strong, Speech, Wavetable, and User Samples) with an analog 12dB state-variable filter, polyphonic aftertouch capacitive keyboard, and a powerful modulation matrix with full MIDI Continuous Controller (CC) support.

💡 How to configure the Arturia MicroFreak in closeby.one▼

To connect your Arturia MicroFreak to your web browser, connect your synth using a USB cable or a dedicated USB-to-MIDI interface.

Open the MIDI Settings panel above, set the Output Port to your connected MicroFreak device, and select the correct MIDI channel (default is channel 1). Once configured, you can map the MIDI CC layout sliders, draw automated parameter curves, and edit patches in real-time without installing any software.

💡 MIDI Routing Guide: For detailed configuration tips, CC parameters list, and step-by-step setup guides, read the full, dedicated Arturia MicroFreak MIDI Connection Guide.

ℹ️ How MIDI CC Sync Works

MIDI CC is a one-way push protocol. Synthesizers cannot be queried dynamically to read their current parameter values. To synchronize these sliders, select your synthesizer's MIDI Input Port above. When you physically tweak knobs on your synth, the slider positions will instantly update on-screen to match.

Firmware & Help Reference

Firmware Version Details

Latest Stable:v5.0.0

MicroFreak v5.0 firmware introduces the custom sample engine, user wavetables, new keyboard modes, and expanded MIDI sysex capabilities.

MIDI Troubleshooting

🚨 Which MIDI adapter does the MicroFreak use? (TRS Type-A vs Type-B)

The Arturia MicroFreak uses 3.5mm TRS Type-B adapters (the included white/gray minijack adapters). Standard TRS Type-A adapters (commonly used by Korg, Roland, or Make Noise) will not transmit MIDI data. When connecting 5-pin DIN cables, always use Arturia Type-B adapters.

🚨 How to prevent double-triggering notes (Local Control Off)

When sequencing the MicroFreak from closeby.one or a DAW, turn Local Control OFF so key presses don't trigger the engine twice: Press [Utility] -> 'MIDI' -> 'Local' -> set to 'Off'.

🚨 Wavetables or user samples not loading in Firmware v5

Use the official Arturia MIDI Control Center (MCC) software over USB. Ensure custom user samples are 16-bit, 44.1 kHz mono WAV files. Longer samples will automatically be truncated to fit the internal memory bank.

🚨 Capacitive keyboard is unresponsive or glitchy

The MicroFreak's PCB capacitive keyboard relies on electrical grounding through your body. Using an ungrounded laptop charger or power strip causes erratic note triggering. Connect the MicroFreak to a grounded USB hub or computer, or touch the metal chassis while playing.
