The Nord Lead A1 49-Key Analog Modeling Synthesizer features an analog modeling sound engine designed to provide virtual analog sounds as well as access to digital waveforms. It has a 49-key Fatar keybed and is capable of 24-voice polyphony and 4 simultaneous synth parts. Its interface is designed to provide simplified access to the synth engine's parameters, including its oscillator, filter, modulation, and effects sections.
The Nord Lead A1 features their Wave Engine with oscillator configuration shortcuts utilizing two oscillators. Start with a single oscillator waveform (a choice of multiple Analog and Digital waveforms), select an Oscillator Configuration Shortcut - pitch, detune, shape, sync, FM, ring modulation, dual Osc or noise - and use the OSC Control 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
The Lead A1's filter section features classic 12 and 24 dB low-pass, a high-pass and a band-pass filter, together with emulations of the diode and ladder filters from the Mini and the TB-303 synthesizers. The Lead A1's modeling of these filters capture the character and response of the originals, allowing flexible sound design
The Lead A1's effects section features two analog models of an ensemble and chorus, modeled on specific vintage synths and adding analog feel. Alongside these, choose from ring modulation, phaser, flanger or drive per slot and in addition a separate delay and reverb for each slot
