Dave Smith Instruments SYNTHESIZERS

I've noticed that, for instance, Patch A1 shows up in many other 
places throughout the presets - all with changes made to it, like 
slowing down the sequencer tempo a lot, or adding feedback, tweaking 
other parameters, etc.

It could be that your original version was editied many times. I had 
no experience with the Beta units though...so if there is a 
difference in the synthesis archetecture, we'd all like to know what 
changes were made and why, just out of curiosity.
