Hi.

So, i was wondering if anyone of those who has built their SY-1's already have the same LFO bleeding problem as me.

I have it on both channels. It's most hearable when output is on about...

I guess u r right, have nothing to measure with right now, will check later. Thanks!

It goes higher as soon as i plug it into the sound card, even if it's just powered from the mains, no computer attached. It goes back to the normal if i switch the S&H on. Also i've noticed that the...

Hi!

Since i've no source of CV voltages, i've dc coupled outputs of my cheap behringer interface, and installed Silent Way plugins to my laptop.

As soon as i plug the output to the tune, the...

Did that, shows 458...but colour code is def. 470)

Okey, if i short the 470 resistor on the top LFO section, it start to at just like the bottom one. Weird, noting seems to be shorted there.

Quadriple checked! haha, all the resistors are right, no bridges, no cold joints, in both lfo section, top and bottom. LFO range is still different...

If you mean 4k7 and 47k sitting next to each other next to 4558 in the LFO section then no, they are on their respective places.

If you refer to those i've misplaced on the voice boards in the...

I have a bit of a funky business going in LFO section somewhere. One voice goes from zero(no LFO), another one starts from kind of medium speed. I didn't change that 470 ohm resistor. The thing is, i...

Fantastic! Will do the adjust today.

Now about the background noise level - i have some always present, which i'm sure is normal, but i'm wondering if it could be higher in case of some mistakes...

Thanks for all your help :)

Up and running after all!

One question - noise mode is audibly quieter that the rest - is that what's that noise trimmer for? No energy to unscrew the whole thing...

Hi!

Finished soldering both boards. It all works, but VCO1 frequency range seems to be way off on the both boards(checked by the person who has the original SY-1 and using it a lot :). In the...

Okey, got it. Maybe it doesn't work, i have only first board built, just see the LFO light blinking, probably doesn't mean anything.

But now i read this:

'Board 1, The rate slider for the LFO might kill the LFO when it’s at bottom. Increase the 470Ω resistor next to it to something between 560Ω and 1k depending on your...

Great, thanks! Now solder the LEDS, and the first board is done, and me done for today too :cool:

I understood :) Great, then i don't have to torture this pcb anymore,lol

and yes, i was wondering why would author design the pcb so two joints are so close to each other...

Thanks a lot!
...

I'm doing my best, but no luck yet, they just stay joined...i hope i won't ruin the pcb in the end.

On the other note - can't figure out where does the long leg of the LEDs go - to the square or...

Hi!

Anyone knows if these two points are supposed to be joined or is it just my lousy soldering job? On the other side there's a 100k resistor and a diode. I have tried my best to...

Hi guys, sorry for English :) I've got the kit waiting for me in Stockholm, going to come in the beginning of July for a week to work in the studio and build it. Problem is that of course all the...

De fick två AR på 4SOUND i Stockholm idag tror jag. Check it out.
