Producing stand-out sounds for live or for the studio, the Lead A1 is ideal for all musical genres. Thanks to its carefully thought-out user interface, the Lead A1 encourages experimentation, allows for far speedier programming than would otherwise be possible, and ultimately delivers sensational sonic results.

At the heart of the Lead A1 is Nord's analog modeling engine. Taking virtual analog synthesis to the next level, this modeling recreates a total analog signal path with uncanny realism, and is capable of immense sonic variety. With 24-voice polyphony and four simultaneous synthesizer parts, the Lead A1 is a true synthesizer powerhouse that goes far beyond the current trend for limited capability analog reissues.

Fundamental to the design of the Lead A1 is a simple yet sophisticated front panel interface. The design is in fact the result of requests from professional players—even the most experienced programmers—who need to create the perfect sound as quickly as possible for today's live or studio time demands. The Lead A1 allows easy patch creation and experimentation thanks to a new and unique oscillator section, preprogrammed modulation matrix, and simplified ADR envelopes. Dive in and create incredible patches far quicker than would normally be possible with a synthesizer of such power.

OSCILLATOR SECTION
The Lead A1's new Oscillator section generates 47 different waveforms from classic analog to digital harmonic and inharmonic waves, whilst unique Oscillator Configuration Shortcuts make programming more immediate than ever. Start with a single Oscillator waveform select an Oscillator Configuration Shortcut—Pitch, Detune, Shape, Sync, Sub Mix, FM, AM or Noise—and use the Adjust knob to adjust the settings of the configuration.

The end result is high-speed programming without the need for the usual complexity of routing and patching, and with the opportunity for ready experimentation. A fast track to stunning sound design for both advanced and less-experienced programmers.

FILTER SECTION
The Lead A1's filter section features classic 12dB and 24dB Low Pass, a High Pass and a Band Pass filter, together with stunning emulations of the diode and ladder filters from the legendary Mini and the TB-303 synthesizers as used in the Lead 4. The Lead A1's modeling of these filters capture the true character and response of the originals, allowing supremely flexible and precise sound design. The filters are super smooth with a warm analog character.

LFO & MODULATION SECTION
The Lead A1 features an LFO with a choice of waveforms and a three-stage ADR Modulation Envelope. The LFO rate can be sync'd to the Lead A1's master clock. The Mod Envelope can be triggered via Velocity and/or the LFO, and includes an Invert function. Thanks to the intuitive design of the front panel it is very easy to see what modulations have been applied and to design incredible sounding patches.

EFFECT SECTION
The Lead A1's effects section features two stunning brand new analog models of an Ensemble and Chorus, modeled on specific vintage synths and adding classic warmth and analog feel. Alongside these, choose from great-sounding Ring Modulation, Phaser, Flanger or Drive per slot, and in addition a separate Delay and Reverb for each slot.

MOD WHEEL AND VELOCITY MORPH
A classic Nord feature, the Morph function via Mod Wheel, Velocity or pedal, allows you to control multiple parameters of the Lead A1 simultaneously. Morph is exceptionally easy to set-up and use—just hold the Morph button and adjust any desired knob.


ARPEGGIATOR
The Lead A1 features four separate Arpeggiators with Up/Down and Random modes and a 4-octave range. Any or all can be sync'd to the Lead A1's master clock.

MASTER CLOCK
The Master Clock function of the Lead A1 allows the LFO, Arpeggiator and Delay to be synchronized, either internally or slaved to external MIDI clock. A Tap Tempo button allows you to easily tap to the tempo of a drummer or to playback tracks.

SPLITS AND LAYERS
Having four identical, equally powerful synthesizers at once opens breathtaking layering possibilities. The Split-mode gives you two 2 slots on each side of the split. A flexible Hold functionality lets you latch and hold slots independently in the background while playing something else on top.

MULTI EDIT MODE
New in the Lead A1 is the Multi-Edit Mode that allows editing and control of all four slots simultaneously. Save this mode as part of a Performance and you have live realtime control over all four slots of the Lead A1.

FOUR OUTPUTS
The Lead A1 features four independent audio outputs with the ability to route each slot to a different output. Plus, control of Pan via the front panel knob is a welcome new addition in the Lead A1.

SOUND MANAGER
The Lead A1 includes the Nord Sound Manager software for OS X and Windows. Sound Manager is a dedicated librarian app which allows easy reorganizing, backup and transfer of programs.

MIDI CONTROL
The Lead A1 features the convenience of MIDI over USB for use with a sequencer or with the included Sound Manager software. All of the Lead A1's knobs transmit MIDI Control data.

THE HARDWARE
Like all Nord instruments, the Lead A1 and Lead A1R are handmade in Nord's Stockholm factory with incredible attention to detail and quality control.

The keyboard version features a Fatar 49-key keybed with a super-fast response. Aside from the keys, mod wheel and pitch stick, the rack/desktop version features a 100% identical feature set, in a design suitable for stage or studio.

With an all-metal chassis, tactile knobs and unfaltering emphasis on quality, the Lead A1 and A1R are instruments designed to last a lifetime.
