That bright, slightly hollow house piano is usually a digital piano or rompler preset rather than a sampled acoustic, which is why the big acoustic libraries never quite get there. If you can't find the exact patch, you can get very close with what you've already got:
1. Start with the brightest, thinnest piano in your library and roll off everything below about 150 Hz with a steep high-pass. The classic sound has almost no body.
2. Boost a wide band around 2 to 4 kHz and add a gentle shelf above 8 kHz so the attack bites through the drums.
3. Compress hard with a fast attack and medium release (4:1 or more). That flattening of the dynamics is a big part of the old-school character.
4. Layer a quiet electric piano or a short bell or organ tone an octave up, low in the mix. It adds the glassy top end the acoustic presets are missing.
5. A touch of chorus, then a short plate or room reverb rather than a big hall, keeps it upfront.
6. Play it in tight stabs with the chords voiced high (around C4 to C5) and keep velocities fairly even.
If you still want a dedicated instrument, look for anything described as a 90s digital piano or house piano preset. That's the family this sound comes from.
