I bought AIR Music Technology Mini Grand and recorded a performance with every preset.
Each example uses the same demo track, which is just under one minute long, to make the differences in tone easier to compare.
AIR Music Technology Mini Grand
Mini Grand is available from the plug-in retailer Plugin Boutique.
This is the Mini Grand interface. It is an extremely simple piano instrument: choose from seven presets, adjust the volume and reverb, and use one additional control to set how strongly playing dynamics affect the sound.

Listen to Every Mini Grand Preset
You can hear the demo track in the Mini Grand overview video published alongside this article. I also exported each preset as a separate audio file so you can listen here.
I play softly at the beginning and progressively harder toward the end, so the differences between presets may be subtle during the first half. Listen a little longer to hear how they respond.
The sound becomes progressively softer from REAL through ATMO, then progressively harder from BRIGHT through DANCE.

My Impressions of Mini Grand
I bought it during a sale for the remarkably low price of ¥500. The quality is far better than I expected from an instrument purchased for that amount.
Its regular price at the time was around ¥8,000. Compared with Addictive Keys in a similar price range, Addictive Keys seemed more expressive and versatile. Even so, Mini Grand has its own uses and is worth keeping available.
The DANCE preset in particular seems as though it could be interesting in EDM.
I hope to use Mini Grand in a future track and share the result in a release or video.
