3. Setup

3.1 Accensione

Connect the provided USB-C cable to the ESSENTIAL L1 and a compatible power source (e.g., USB power adapter, computer USB port, or power bank). Ensure the power switch is in the 'ON' position. The OLED display will illuminate, indicating the device is ready.

3.2 Cunnessioni Audio

For audio output, connect headphones to the PHONES jack or use the MAIN OUT to connect to an amplifier, mixer, or audio interface. The EXT. IN allows external audio signals to be processed through the synthesizer's VCF.

3.3 MIDI and CV/GATE Connections

Utilize the MIDI I/O (TRS, Type-A) for connecting to other MIDI devices. The USB-C port also supports MIDI over USB. For modular synthesis integration, connect compatible gear to the CV/GATE/SYNC I/O ports.

4. Operating Instructions

4.1 Basic Sound Generation

Adjust the VCO, VCF, and VCA parameters using the dedicated sliders and knobs to shape your sound. Experiment with the MODULATOR section to introduce movement and complexity to your patches.

4.2 Using the Sequencer

To create a sequence, enter notes using the integrated keyboard or an external MIDI controller. Use the sequencer controls to record, edit, and playback patterns. The SONG mode allows chaining multiple patterns for longer compositions.

4.3 Arpeggiator Functions

Activate the arpeggiator and select one of the 5 available modes (up, down, up & down, random, order). Adjust the rate and range to create dynamic arpeggiated melodies. The Trigger Edit function offers advanced pattern manipulation.

4.4 Real-time Control and Performance

The intuitive user interface with dedicated controls and an OLED display provides immediate feedback on every action. Utilize the GLIDE and MODULATION sections for expressive real-time performance.
