YC-30 Top-of the line single-manual. 44 Treble Keys, 17 Bass keys, switchable to extend the Treble section. Adds a few new voices (Marimba, Fuzz , Attack and Sustain) over the YC-20, and a couple of really unique features:

- Portamento or "pitch ribbon" - used to make theremin-like sounds (not a "pitch-bender", as you might expect). It has it's own 16', 8' and 4' flute voices. The range of the pitch ribbon is 3 octaves. This strip is NOT physically the same as the one on the YC-45D - they're not interchangeable.
- Presets - two sets of miniature-tone levers that duplicate the function of the regular Ch I and II levers. They can be preset and selected at the touch of a switch, similar to Hammond presets, but they can be adjusted right from the top of the organ. I think these are quite similar to the preset bank found in the CS-80 synthesizer.
