Casio's MT-100 toy keyboard is reborn as a free plug-in for macOS and Windows - CDM Create Digital Music

cdm.link

Casio's MT-100 toy keyboard gets a modern revival with Sample Science's Retro Cazio plug-in, offering a nostalgic trip to the 80s for free. The plug-in provides a curated selection of high-quality samples from the original MT-100, including its iconic drum sounds and voice presets, enhanced with contemporary features like multi-LFO and reverb. However, it falls short of replicating the full capabilities of the original hardware, lacking some of the MT-100's unique vibrato and sustain features. While not a complete substitute for the original, it’s a delightful freebie for those seeking retro vibes on macOS and Windows.

It's just a preset home keyboard, but pretty fun to jam on. Unlike the sought after old Casio keyboards that have sound editing capabilities, this one only has an EQ panel (which is still pretty cool).
