Yamaha CS80

Hi everyone.

Well, yesterday may have been the first time a bunch of people got 
together to learn to tune a CS80 since some training sessions at Yamaha 
thirty years ago!

Scott (who's in this group, and whose CS80 I added the Kenton MIDI kit 
to), wanted me to clean up a few voices that had drifted a bit since I 
last tuned it (a little over two years ago).  He figured we'd make it a 
party, and invited a couple of other CS80 owners, including Shawn from 
Analoghaven.com and Steve. It was a little crowded in Scott's studio 
loft, with the ton of gear he has (and the Obie 4-voice wasn't even 
there!), but we managed.

It took a long time, partly from schmoozing, partly from letting 
everyone try tuning a voice card, and a lot from a D'oh! moment: Scott 
has the MIDI in of the CS80 hooked up to a Kurzweil MIDIBoard. It's a 
great setup for recording poly-aftertouch performances on his Mac and 
then controlling the CS80. However, the spring-loaded pitch and mod 
wheels of the MIDIBoard don't have a dead zone and don't always go back 
to zero. Apparently, during our pizza break after the first four voices, 
the wheels got hit, and the pitch-bend was slightly off for the next 
four sets of cards.

In the end, it was all in tune. I think we also came up with a very nice 
and fast tuning procedure which I'll write up in the next few days.  
Looks like I may be putting in a couple more Kenton kits in the near 
future, too.  Then we have to get all three MIDI-ed CS80s in one room, 
played from the MIDIBoard, plus Scott's Obie 4-voice via a Doepfer 
MIDI-CV interface. I think the sound will violate several international 
weapons treaties!

that sounds killer! damn, wish i was there....i cracked mine last week to touch up a few voices and realized that its definitely not the most miserable process in the world....OBXA is definitely more annoying....

Many many thanks for the great company and sharing
your tuning insights with us - I'll host the next CS80
tuning party at my studio! That was great fun. Maybe
there are other LA-area CS80 members interested if we
do another one?

[I'll try not to hit the mod wheel on the midiboard
this time!!]

cheers

Wow- sorry I missed this. Where was it? I must have missed the  
original post.

It wasn't announced here. We can try that in the future. This one was in 
Santa Monica, CA.

That reminds me - a couple of years ago I posted about a CS80 group 
map.  It's still here: http://www.frappr.com/cs80.  Please add yourself 
and we can see who's nearby!  Not surprisingly, there are many of us in 
Southern California.  Maybe we'll have one at my place (Irvine) soon, 
since I should have between one and three CS80s passing through in the 
near future.

Yeah, that was loads of fun David.  I am glad you could make it out.  We all learned a ton about tuning the beast!!  Can't wait to see Shawn's finished CS80.
