A nice keyboard action would mean hopefully Polyphonic Aftertouch. :-)

You are one of the few, Laurie, who is passionate enough to include the beast in your live setup. As Bernie Worrell said to me when asked about the difference between the MiniMoog and the newer Voyager, "Ain't nothin' like the real thing!"
I guess "portability" is relative. ( ;

I assure you, my CS80 has been portable and used live since 1979...
last road trip was 2013 and has been moved to 3 locations since that...
I also know lighter and more portable applies to every other piano type keyboard besides a real piano :)
can't wait..

The video is heavily hinting a Yamaha CS reboot of some sort or another.
I guess a virtual analogue with hands on control and nice keyboard action,
an analogue signal path is too much to hope for i would guess

The keyboard made by "someone who plays the piano" seems contradictory to the portable aspect, however.
Yamaha filed the application to trademark the name, "reface" last year (June 5, 2014).
All will soon be revealed.

Hello everyone!
Good to see a bit of traffic here lately after a long lull. I know why I've been so distracted and I assume most folks have lots of stuff going on in their lives.
I'm finally getting back to a long-term CS80 renovation / mod project after moving and job changes and other fun stuff. I have a question for any of the techie types here. For review, all the digital logic in the beasts use standard (and mostly still available) CMOS chips. These are old DIP packages that only fit a hand full of gates in each chip. They are all run off of +8.5v and -6.5v. This weird arrangement fits in the 15-volt supply that the chips can handle and being offset allows analog switch chips (e.g. 4051, 4016) to process the analog control voltages and audio signals that are bi-polar around zero volts.
So, I want to add a bunch of new logic including an FPGA (tons of re-programmable gates) and a processor (maybe Arduino).

Again, the catch is that this board has 3.3volt digital I/O - which is actually pretty high compared to the latest chips! So, I need to translate a lot of signals. The old standbys were the 1488 and 1489 chips that were design to translate from 5volt TTL to +/- 12v (or lower) for RS-232 serial ports. I might be able to use these but they would take up a ton of room and I'm not sure if they'll work with 3.3volt instead of 5volt. I looked around a bit yesterday but found tons and tons of possible chips and was hoping someone here might know a good chip to use. I'd like something that's 3.3volt on one side and up to the +8.5v/-6.5v Yamaha levels on the other side. DIP or SOIC package would be fine and I'd like 8 or more channels in each chip with versions for one-way and bi-directional.
Any ideas on this idea in general? On the Mojo board? On the level-shifters?
Thanks and hope everyone is having a happy, music-filled summer!

Hi all,
?
I've been browsing the archives to no avail. I would like to have my tech go through my 50 and have some minor issues fixed, like unsollicited portamento on some voices, pitch occasionally drifting upwards with long release etc. I seem to remember this has something to do with some of the caps on the voice assigner board going bad and perhaps with replacing the 4XXX CMOS component parts. Any pointers as to what to replace in what sequence?
?
Also, I would like to have him calibrate internal levels. Any caveats?
?
Thanks,
?
Stephen (much to my amazement, my most recent message actually made it to the list... wow!).

This is pretty loud. And as I said, it seems to be eminating from the PSU... As in you can hear the power transistor on the -15Vrail whining away, if you've got the audio out disconnected. But it manifests on the audio out as well. Round about 5KHz I reckon.

Hi
Still having issues with this CS50 PSU.
I've got a horrible high pitched whine all over everything. If I turn the amps off, I can actually hear this noise emanating from the PSU.
If I put a probe on the lines, I've got oscillation on both the + and -15V lines. Much worse on the -15V line.
I've recapped it, changed all the transistors, and diodes (Apart from the rectifiers)
Changed the 4458, but no change.
What's really odd is that if I touch the anode of the -15V zener (Opamp supply) with a scope probe, it collapses the Opamp supply.
Also... If I remove voice cards 3 and 4 from the rack and the problem goes away... even though they're still connected to the power.
Any incite, or suggestions? most welcome... I've got to get this thing sorted in a couple of weeks, so a client can use it on a session. :-s
