Retro Cazio is a rompler inspired by a classic toy keyboard from the 1980s, capturing the nostalgic charm of that era. It faithfully recreates the unique digital sound character of the MT-100, a device released in 1983 that utilized the NEC D931 chip for sound generation. Every tone has been carefully sampled with high-end recording gear to ensure authentic and crisp audio quality.

The instrument offers 20 distinctive retro keyboard sounds along with a dedicated drum kit, providing a range suitable for vintage-inspired music production. Its sound-shaping capabilities include multi-LFO modulation, adjustable highpass and lowpass filters, and built-in reverb effects, allowing for creative manipulation of textures. Glide and amplitude controls further enhance expressiveness and dynamic control.

Users can switch between three voice modes—polyphonic, legato, and mono—enabling flexible performance options that cater to different playing styles. This combination of authentic sampled sounds and intuitive controls makes Retro Cazio a compelling tool for producers seeking classic 80s toy keyboard vibes with modern usability.
