[sdiy] sort of OT: cheap arpeggiator to make my Roland MKS-50 sound like a Jupiter 8?

[anthony]

After reading that Duran Duran used the Roland Jupiter 8's arpeggiator all 
through the album "Rio" on the Vintage Synth Explorer site, I took a closer 
listen to the album after many months (yes months - I like Duran Duran - sue 
me!) and decided that I would very much love to have a simple MIDI 
arpeggiator at my disposal - on the cheap. I have thought that I could 
definitely use my Yamaha QY-10 in this regard - just punch in an arpeggio 
and then put it in a pattern slot - and it would play over and over again. 
I'm glad the QY-10 had much more user pattern space than song space. I never 
dreamed of using the thing for whole songs anyway - mostly a drum & bass to 
go with my guitar. But having my MKS-50 is changing things. I wonder if I 
could run 6 arpeggios at a time in the guitar mode - well it'd be 3 using 
QY-10 patterns, 4 if I tried to use one of the MKS-50's percussion tones 
withthe rhythm section...

So maybe I'm answering my own question here, but I swear I've seen a cheap 
MIDI arpeggiator before. I saw a really cool Oberheim one on eBay, but it 
was NOT cheap.

I may start doing some serious thinking about one of the MIDI Box projects 
of Thorsten Klose's. I already have the LCD display for one. I just can 
never decide what configuration I want to settle on. I'd like to emulate a 
PG-300 too if the MIDI Box can do Sysex... But I digress...

ideas?

cheers,
