I’ve gotten several requests on how to hook up the Casio Sk-1 with a Getlofi1799 Oscillator so I’ve quickly drawn up a diagram for hookups. According to other sources the clock input can be directly injected without cutting the trace. That may be possible but there are bootup problems if the clock isn’t at it’s original setting so you may need to add a switch regardless. The note about the optional 500 ohm resistor is only if you notice your sk-1 is now out of tune for wiring to the clock lines. this should drop pitch to a range where you can fine tune the keyboard back to A=440. Access to the fine tuning is available thru the bottom plate of the sk-1. Click thru on the pictures to get an exploded view of the diagram.
this is pretty cool. are there sound samples of the sk-1 with the 1799 installed anywhere? i’d like to hear what this does….
just click on the link above for the ltc1799.. there’s a sk-1 video i made when i first started using the ltc1799.. after the video i swapped out a 500k video for a 100k. it can handle 500k and can get really low but a 100k can get pretty low and offers a more linear response and a little better control over the upper registers.
thanks spunky. those videos are great.
the CM gave me one of these things at circuitastrophe, but i still have yet to put it in anything….
speaking of.. any idea if circuitastrophe is going to happen again?
yesnoyesno did we meet maybe?
circuitastrophe is in not a no for sure but not a yes yet. a maybe.
i think cm is at v. 1.2 on that board from circuitastrophe so layout is different.
at 1:45 in this clip there’s a little example of the ltc1799

any suggestions on good places to grab an sk-1 for cheap?
Hi Spunky,
I’m really interested about putting the pitch mod with the LTC1799 on my Yamaha VSS30!
Do you have any schematics like the one for the Casio SK1?
I’ve put the LTC 1799 in my SK1 it work great THANK YOU!
I’ve got also a Casio VA10 and just have a look on your vidéo on Youtube. How can i get this kind of sound with my Casio VA10
Q: have you added any modifications for audio out w/the SK-1? do you use the built in 1/8″ audio out or have you added an external 1/8″ or 1/4″ audio out?
