Jun Murakami Synth81Z v1.0.2

Software Overview

---

Synth81Z focuses on the sound and behavior of the Yamaha TX81Z, including its eight selectable operator waveforms and the distinctive "Lately Bass" preset associated with the instrument. Development was based on detailed hardware measurement, covering operator phase resolution, waveform table rounding, envelope timing, LFO response, velocity and controller behavior, and the frequency response of the DAC and output stage.
The synthesizer supports up to 32 voices of polyphony and includes an eight-part Performance mode with layers, splits and multitimbral setups. Software additions such as MIDI control, DAW automation, an editor and librarian, and an integrated effects rack extend the original hardware workflow without changing the hardware behavior when the polyphony is set to 8 voices.

Why Choose Jun Murakami Synth81Z

---

Synth81Z combines detailed TX81Z hardware modeling with features intended for software-based production. The 8-voice mode can reproduce the behavior of a single original chip, while higher polyphony settings provide the equivalent of stacking multiple chips. Its Performance mode, MIDI integration, librarian tools and effects rack also make the synthesizer practical for DAW-based workflows while retaining the distinctive FM character of the original instrument.
