Yamaha AN1x, produced by Yamaha Corporation from 1997 to 1998, is a DSP-based analog modeling synthesizer (a.k.a. virtual analog synthesizer) and was marketed as an "analog physical modeling control synthesizer".
Although the synthesiser uses very similar casing to the CS1x and particularly the CS2x, those use sample-based synthesis rather than virtual analogue technology and are not directly related to the AN1x: although they share the manufacturer, overall user-interface, and marketing as "Control Synthesiser" devices (see below), the engines used to create sounds are significantly different.
The AN1x has a maximum polyphony of 10 notes, although the actual polyphony depends upon whether the voice is Single (monotimbral; a single Scene) or Dual (two scenes layered or split), whether it is in Mono or Poly mode, and whether the note-multiplying Unison mode is active. Dual mode halves polyphony to 5 per voice, dividing each of the two 5-note processors in the synth to one Scene respectively. In Mono or Dual modes, Unison uses five notes per key per Scene for a Single voice (1 processor x 5 notes) or two notes per key for a Dual voice (2 processors x 1 timbre per processor); thus, in Dual/Mono/Unison mode, the synthesizer is monophonic for each of the two Scenes. In Poly mode, Unison is only possible for Single voices (each key takes 2 notes, of the same timbre, one from each of the two processors).
The voice architecture resembles a twin-oscillator with multi-mode filter design. Available waveforms are: PWM, Saw, Square, Saw2 (behaves in a different way than "Saw" when used with PWM), and Saw/Square "mix". Additional waves (Inner1-3) are available for OSC1 in oscillator sync mode. Triangle and Sine are achieved by altering the Edge of Pulse Waves. The Edge tool (wave shaping), also enables extensive intermediate waves. OSC1 additionally has a tuneable 'slave' (Sub) oscillator when activated via multiple 'sync algorithms'. The AN1x has 4 FM Frequency Modulation algorithms, where OSC1 is modulated by OSC2. Finally there is ring modulation and white noise.
