AY3 MKII turns the unmistakable AY sound into a real performance polysynth: six voices, dual-chip stereo width, instant arpeggiation, onboard sequencing, AYMID song playback, live remix tools, and a compact control matrix that keeps the chip under your hands. Classic computer tone, widened and made playable The AY-3 sound is direct, bright, and full of character: square-wave melodies, crunchy basses, noise textures, and glassy old-machine harmonics. AY3 MKII keeps that identity, then gives it the control and stereo movement needed for modern hardware sessions. Two AY-3 chips create a dual-chip stereo architecture with three voices per side. Use it as a six-voice polyphonic synth, stack all six voices in unison with dedicated detune, or split the voices into instant chord shapes with six built-in chords. AYMID playback becomes a performance source AYMID support lets AY3 MKII receive and play song data from Ay_Emul, but the interesting part is what happens next: you can remix incoming material in real time, bend it away from straight playback, and use classic song data as live performance fuel. The 16-step sequencer handles gates, pitch, and noise, while four pitch-modulation/LFO modes and four arpeggiator modes add movement fast. Dual synchronised timers give patches and playback a wider, more animated stereo image than a single-chip design. The right clock for the sound you want AY3 MKII supports Atari ST, ZX Spectrum on Rev. B boards, and Legacy clock modes. Legacy mode keeps compatibility with older 2 MHz behavior, while ZX Spectrum mode on Rev. B boards gives the pitch reference expected for that sound. Hands-on, not menu-bound The 5x6 mode matrix gives direct access to volume, pitch, noise level, envelope assignments, arpeggiator modes, sequencer routing, and more. Five high-quality pots, an endless push encoder, 40 subtle white LEDs, sustain pedal support, improved voice allocation, and full MIDI CC control make AY3 MKII feel like an instrument instead of a chip demo.
