Ahh, OK, I see what you're trying to do. You want to do a pitch LFO, right? If that's the case, the SK CV outs are not what you want. The SK CV's are for...
New to mods and would like to do a cv sync with my first experimentation on the SK 5. Can someone point me twards a step by step guide I looked in the files...
OH sure i see thanks again! would i be able to combine two of the LFO circuits and connect them to the same point using the vactrol in order to have 2 VCO's?...
Yes, you can combine them. What were you planning to do with the 2nd VCO, some sort of ring modultion as well? Cheers, graham ... LFO circuits and ... VCO's?...
You could try checking out this thread here: http://launch.groups.yahoo.com/group/CasioSK/message/219 It was regarding doing that with the SK-1 though. Still...
i was planning to connect both of them to the pitch so i could combine waveforms, e.g square wave on one and triangle on the other. would they still work...
Yes, they will. Actually, you'll get some unique sounds out of it if the LFO rates are set at different rates to each other. Cheers, Graham ... combine...
Hi. I'm bending my sk-1. I've gathered all I could find about it and experimented on that: Pitch (just pot and body contact), poly, skew, found the drums...
... that link anymore. So what I remember is I should solder the direct out to the negative leg of a 4.7uf capacitor, then pass through a 3k3 resistor and out...
Sounds like you've been pretty industrious! "would like to have your opinion on them, just out, after the envelope/pitch circuits (adsr?)" Yes, and depending...
Well I did those 4 outs but the volume is really low, drums volume very low, melody I can barely hear, bass and chord I can't even hear. Is that normal? I...
Ok, then try tapping each voice after each of its amplifying section, before they're combined together. On each of the voice lines, this would be just before...
Oh, and for the drums, I'm not sure. There doesn't seem to be an amplifier circuit for it. Try tapping it at points along the drums line, starting directly out...
Yep, I got to the multimeter test probe pretty fast. I found some interesting things: C38,42,46,50 are the spots to tap the 4 voices out. The volume is good ...
hi, i have this circuit almost built. i want to connect it up to the voice and audio 1 out. should i do the 'vactrol' method in connecting it? i haven't...
Yes, just connect the vactrol's photoresistor to the SK circuit board points, then just attach it to the LFO's LED. But check to see that it works first. After...
hi, i'm having troubles changing a 1/8" jack output into i 1/4" jack output. the problem is i removed the old output, 1/8", and i am left with three wires red,...
Are you talking about your SK-1 project? I think the output jack uses the black wire as the ground, and the other 2 are for the audio out AND for disconnecting...
i tried to make the slow ad mod on my sk-1. the attack is slowed down, but the decay is cutted up after a while. it's a great effect if you use the other...
Can you describe exactly what the decay is doing? Maybe even post up a sound clip into the files section here? I might be able to tell whats happening....
Hey everyone, I'm new here. Been stalking the list since a few days ago when I found an old SK-8 I didn't know I had. A question about this LFO circuit, before...
Hi I am interested in making this circuit for my SK-1: http://tinypic.com/view.php?pic=2wpjz9s&s=4 But I have a few questions before I begin. Firstly what are...
Hello there, I recently bought a Casio SK-1 from a charity shop. It was working well for a few days, and then the keys C4#, D4, D4# and E4 stopped functioning....
Hi Thomas! Yes, it's just a square wave output, but I have seen some mods to it that enable it to get a roughe triangle wave out of it too. I must get round to...
Howdy, It sounds like you need to resolder the ribbon cables at the keyboard and PCB ends. That happens to me a lot with SKs after bending them. Rig ... won't ...
