Amphitryon features 3 oscillator banks, each of which can operate as single or double oscillators, providing a maximum of 6 oscillators for rich polyphonic sounds. The oscillator banks can interact with each other in a variety of ways (synchronisation, FM and AM), and can also modulate the central filter unit. Further, Amphitryon offers not one, but 3 FM modes. Each oscillator bank also has its own multi-mode filter for precise sound-shaping.

Bank 1 and 2 can operate in wavetable mode, utilising Amphitryons unique wavetable system. For each snapshot, any 12 waves can be selected from the master wavetable bank. The selected waves can then be morphed in realtime by any of Amphitryons modulation sources.

Using the wavetable editor, waves can be drawn by hand or generated using a range of editing and generation functions. Generated waves can be mixed together into a single shape that would otherwise require great processing power. The wavetable editor combined with real-time wave morphing results in literally infinite sonic possibilities.

In addition to the 3 oscillator filters, Amphitryon features a powerful central filter unit, featuring two multimode (9 types) filters, pre-amps, 3 FM modes, independent AM of both filters, peak limiter and a feedback unit. For complete sound control, each oscillator bank can optionally bypass the main filter.

Amphitryon’s array of modulation sources (envelopes, tables, lfos, midi controllers) can be freely routed to virtually all parameters, (including each other). The tables can be driven by clock as in 3X, but table position can also be controlled by velocity, mod wheel, key position and the envelopes. The tables can also trigger the envelopes for rythmic patterns and phrase synthesis.

Amphitryons complex wave generation system is further complimented by a waveshaper, delay and chorus effects, and two EQ units.

Despite such power, Amphitryon remains CPU friendly due to efficient programming. On an Athlon XP 2400, Amphitryon uses 6% - 18% of CPU, depending on the snapshot. By comparison, 3X uses 3% - 11% of CPU on the same system.

My favourite Reaktor synth. In terms of flexibility, sound and design, this cannot be beaten... the wavetable editor is absolute genius.

Phil Durrant (AKA Sowari), Musician, UK

This is one of the best synths I've ever heard. Period.

Cliff Douse, Freelance reviewer, MacFormat, Computer Music and Future Music, UK

The design is so mature, far exceeding any other Reaktor work I’ve ever heard or seen.

Drew Hill, Musician, Australia

This is amazing! Without a doubt, the best implementation of wavetable synthesis that I've seen in Reaktor... Instruments like this take Reaktor to a whole new level.

Eric Wistrand, Reaktor builder, USA

My favourite synth, software or hardware. Better than Absynth and better than the Waldorf Microwave XT... I know this is the best Reaktor synth out there.

Jeremiah Savage, Musician, USA

This synth is so flexible - a thing of beauty.
