Despiste the record quality sound not being so good, it is easy to feel the great sound this machine makes.
Look the demo of interactive programming. User comment:
At 4:40 this video shows a pad that you can create live using the JD-800's effects and sliders. I am using a Roland DP-2 footswitch to hold the chord down while I set the JD-800's phaser & delay. Then I change the cutoff and rez, and pitch with the "pitch coarse" knob. To get the "whoosing" effect you could set LFO1 on the filter. JD-800's resonance in full effect here but this is not using high settings. Other sounds in this video include crystal rhodes, strings, piano, PPG sounds, catherdral organ, of course basses and leads.
