Oscillator Section

At the core of the Nord Lead A1 is its sophisticated oscillator section. The synth includes multiple waveform models ranging from traditional analog to advanced real-time algorithmic waveforms. The oscillator section provides 11 configuration options, allowing detailed adjustments in pitch, shape, sync, and more. Users can explore a variety of waveforms including pulse, additive, FM, and formant synthesis.

Filter Section

The filter section on the Lead A1 is equipped with a multi-mode filter that includes 12 dB and 24 dB low-pass filters, band-pass, high-pass, and ladder M and TB characteristics. It features adjustable cutoff, resonance, and envelope controls. The filter can be tailored with velocity control and distortion for added versatility.

Modulation and Effects

The modulation section includes an LFO with multiple waveforms and polyphonic envelope mode options. The arpeggiator offers a range of up to 4 octaves with various modes, and the effects section provides delay, reverb, and an assortment of modulation effects. The delay includes tap tempo and stereo ping-pong options, while the reverb section offers room, stage, and hall algorithms.

Performance Features

The Nord Lead A1 shines with its performance capabilities, including voice modes like polyphonic, legato, and mono. It supports layering with four program slots and offers detailed control over each sound slot. The performance section is complemented by the Master Clock sync function, which coordinates the arpeggiator, LFO, and delay with external MIDI clocks.

Memory and Connectivity

The synthesizer includes extensive memory options with 400 single sound programs and 200 performance slots. It features four independent audio outputs, a headphone output, and MIDI capabilities via DIN connectors and USB. The synth also supports system exclusive bulk dumps and MIDI control change messages.

Special Features

The Lead A1 introduces unique features like the ‘Like’ button, which allows users to save and compare patch variations easily. The Mutator function lets users create patch variations or randomize settings for new sounds. The Extra Fat Unison mode provides thick, rich unison sounds comparable to vintage analog synths.
