A begginers doubt about LFO on Casio SK 1
« on: September 26, 2015, 09:33:16 AM »

Hi my friends.

Iīm working on my SK 1. I am not very good with electronic but I think I.m doing a good mods.

My question:

I have done the 555 circuit to put an LFO on my SK 1 but.....is terrible, I donīt know where on the circuit table SK 1 I have to sold the different wires, I mean, Ground, power....sound from Sk 1 and the OUT.

I know, perhaps they are stupid questions but I donīt know who can help me but you.

Thank you so much!!!!!

DAVID.

What are you wanting the LFO to do? 

The Ground and 5V+ points i'd get by using my multimtere and finding which leg of one of the ICs has 5Vs going into it.
As far as the 'out', i've used an LFO for vibrato style pitch changing (though the SK1 has this built in).  What did you want to do?
