My good friend (and long time music collaborator) has made not only a super nice sample pack of rootless chords but also a robust chord voicing resource for anyone interested in approaching interesting chord voicing.
This pack also includes MIDI data for all chords, so if you make a great progression but want or need a different timbre/sound, just drop the MIDI data in.
The Bandcamp link (above) contains examples of the sample pack by the man himself. The link in the Bandcamp description hosts the sample pack.
If you like it, certainly consider throwing him some change through Bandcamp!
