Hi,

I am having some trouble with my 3 scopes. One is an SRB.

How many STDM cables should I be using?

When I use one, I can't max out the polyphony on synths and there's only so many I can load before it starts making a weird noise.

When I used 2 cables, I completely lost all synth output. May be a bad cable. I have enough connectors to make 5 cables, if required.

Thanks for your help,

there's no correct answer.
it depends on a number of factors including exactly what devices you use and in what order they are loaded. just try it and see.

Well, the problem is that with more than one cable, I get a horrible digital noise. I've tried up to 5 cables. I am gonna try shuffling the cards around on the motherboard.

Still getting bad digital clicks, several per second, with all 5 cables installed.

i don't think that s/tdm cables cause this....but if 5 cables don't work, they don't work.
i suspect there's something else involved. have you cleaned contacts? are you certain you are connecting cards properly?

Yeah, I followed that article to make my cables.

It worked fine with just a Pulsar II and 2 Scopes. Changing the Pulsar II to an SRB complicated things.

maybe it's the srb itself...

Could be. I'm gonna clean the contacts on it. I almost got it to work by switching cards around again...

Looks like there's a problem with the SRB. I am only running 2 cards now and they're working fine (5 connectors). Got two 16 poly Profits 5 loaded and works like a charm. I am gonna be returning the SRB.

Thanks for your help.

too bad.
i'm glad you found the culprit.

Yeap, just confirmed it by running just 1 other card and an SRB. Same noises happens. I'm sending it back. The seller is cool with that. I just have to cover the shipping.

Thanks,
