What Makes the Synthrilla Froggie SF-60 Unique

There are countless Casio MT-60 emulations out there. None of them sound like Thriller.

The Froggie SF-60 is not a synthesis-based recreation, and not a generic 80s toy keyboard plugin. It is built from 49 chromatically recorded samples of an authentic 1981 Casio MT-60 unit, C0 to C4, captured with studio-grade precision. No modeling, no shortcuts. The actual instrument Michael Jackson and his producers used, sampled note for note.

What Makes It Unique

The Thriller Mode. One single key — C#0 — holds the exact note that opens the Thriller outro. We isolated it. We labeled it. We built a dedicated mode around it, with matched EQ and reverb to bring you within millimeters of the final mix. No other plugin in the world hands you that key on a platter.

32-Voice Polyphony with per-voice processing. Each voice runs through its own VCF (6 filter modes: LP12/24, HP12/24, BP12/24), its own envelope, its own LFO routing. Stack rich chord work, layer bass lines, build pads — the Froggie behaves like a modern instrument, not a one-trick novelty.

The Looper with Waveform Display. Zoom up to 50× into any sample. Define custom loop regions. Turn a single key press into an evolving texture.

6 FX Engines. Multi-mode delay (6 variations), Dattorro plate reverb, pitchbend with Lagrange interpolation, glide/portamento up to 100ms — production-ready, no additional plugins required.

HUM. A humanize knob that introduces 0–100ms random onset delay. Because nothing from 1981 was ever perfectly in time, and modern sequencers make things too clean. Put the groove back.
