This synth is based on iPD synthesis as used by the Casio VZ range, but it has been significantly expanded."

Interphase Cartograph
"Interactive phase distortion, the Casio VZ engine rebuilt and then extended — two modules per line, one bending or ring-modulating the other, with AM and through-zero FM added.
Interactive phase distortion — iPD — is the technique behind Casio’s VZ-series synthesizers of the late 1980s. Rather than mixing raw oscillator waveforms, it pairs two sound-generating modules into a line and lets one shape the other: bending its phase, or multiplying into it as a ring modulator. The character sits between subtractive and FM — glassy, bell-like, vocal or metallic, and equally capable of plain tones when the interaction stays subtle.
Classic reproduces the original four-line, eight-module architecture with eight iPD waveforms and eight-stage envelopes. Extended adds two more lines, twelve modules, a sixteen-waveform bank, and two interactions the hardware never had: amplitude modulation and through-zero FM. The two are switchable from the header at any time.
Around the engine sit a sixteen-route modulation matrix, a bipolar pitch envelope, patch vibrato and tremolo, an arpeggiator, microtonal tuning with historical temperaments, six performance macros, unison, two LFOs and a randomiser that can roll a whole patch or mutate the one you have. The display is drawn in an OLED style with cyan and amber themes."
