I´ve checked the late SR-JV08-06 Dance Expansion and found the following patches, all made of internal waves only:

088 ResoLoot: Int-B 26 Synth Saw 1

089 Square Tone: Int-B 39 Synth Square

090 Trianglular: Int-B 45 Triangle
Int-B 46 Sine

093 Reso Pad : Int-B 29 Synth Saw 3
Int-A 213 JP Strings 1A

095 ResoSequence: Int-B 26 Synth Saw 1
Int-B 27 Synth Saw 2
Int-B 29 Synth Saw 3

More, the following uses internal and expansion waves, but the tones that uses the expansion are TURNED OFF, and only the internal tones are turned on:

198 Oper'Ambient
215 Nice-n-Easy

The expansion tones only adds minors changes to the overall character of the patch...

I´m still checking the Session board.
