[sdiy] trying to understand appregiators in late 70's synths

[Bob Weigel]

It's also one of the best in my opinion :-).  Other arpeggiators you 
have to hit right on the money or it's train wreck time.  Eg. Akai AX60 
eg. Korg poly's etc.  I have a Jupiter 6 on the bench right now for the 
first time and will get to see how it is.  No Europa but anyway Roland 
definitely did a great thing for 1978 in the JP4.  It's one of the 
synths I just would hate to lose for that reason and it's amazingly 
spacy sound :-)  Being the spacy guy I am.  Hehe.

Anyway I think there were various other analog sequencers and 
arpeggiators before that but not in a polyphonic box.  The DS-2 digital 
sequencer by Oberheim could be used with the SEM series stuff and so 
on.  I don't know how the JP8 works either..haven't tried one of those.  
I need to fix up my OB8's again.  That's one of my goals for this 
winter.  I didn't use the arpeggiator much on it while I had it running 
so I'm not sure how good it is either.  But the JP4 is MONEY. :-)   -Bob
