Just some fancy base line and some drums and synth sounds. It's instrumental. The overblown flute in the end is a little too harsh, but the JV80 it was created on is at my parents place at the moment...I actually created many of this kind of tracks, using just the MIDI from an old Cubase and then a MIDI cable to the JV80. This ran fine on an old Pentium PC, without any noticeable latency. Long before audio and virtual effects or instruments came widely available.
