VS-100 Loses S/Pdif Sync

Re:VS-100 Loses S/Pdif Sync (madoues)

I have the same problem with a VG-99 guitar processor, with all firmwares, but a bit better since 1.19. All I have to do is turn down the volume on my guitar and the VS-100 looses sync. Turn up volume, sync returns in a few seconds. Changing patches does it sometimes, sometimes not.

Cakewalk have confirmed the bug with a VG-99 they borrowed, but have not fixed it yet, to my knowledge anyway. Since you are only the second person to point this out in almost a year, I suppose you shouldn't hold your breath for a fix anytime soon.

It's too bad, the VS would have been the perfect tool for me. I still use it, but this problem makes the s/pdif input totally useless for me.

Hey, CW could we have a bit of news on this? Even an explanation why it can't be fixed would be better than nothing. Or is it just that hardly anybody is complaining?

I did some more tests, but only when I turn VS-100 on, connected to XS8, I am getting "Coaxial Clock 44.1kHz" message (right after the VS-100 Logo screen). Then unit never shows it or anything similar. Just in case, I have VS-100 v.1.30 and XS Firmware v.1.51.3.

I'll play with Main Mix control more tonight, but I think I did it yesterday because at the beginning there was no sound in my headphones and I had to turn all related knobs up and down several times until I get proper level...

Found a 75 ohm cable. Two feet long, unfortunately, but OK for a test.

The VS-100 still loses sync, but not on every try now.

But, I found another way to make it fail everytime: Connect, play something (one note ppp is all it takes), and let it go to silence. Then, rotate the Main Mix control. It loses sync. It's not a loose connection because if I connect, but don't play anything, and rotate the Main Mix, it does not lose sync. I can flex the cable and move the gear around, and it's solid. Since the Main Mix is a digital encoder, it might be firmware problem.

Think I need to call support.

Thanks, Iaroslav, for checking this out. At least there's nothing fundamentally wrong with this setup.

It could be the cable that I'm using. I thought it was a 75 ohm cable based on its thickness, but it doesn't have any markings on the jacket. Somewhere in the bottom of a box is a real 75 ohm cable ...

Hi, MurMan!

I just tried your setup by connecting my XS8 to VS-100 in stand-alone mode via S/PDIF and everything seems to work perfectly fine. I am not getting any messages about re-sync or anything else VS-100 display.

I tried Full Concert Grand as well as several Pipe Organs and all the time after I stop playing everything goes to silence and levels on display just go down.

Let me know, if you would like me to try something else.

I ran into a problem last night and I thought I'd see if anyone had seen a similar issue.

I tried connecting a Motif XS to the VS-100 running in standalone mode using the S/PDIF connection. It sounds great, but I started hearing occasional crackling noises.

I tracked it down to a very repeatable sequence. When I play a medium to loud passage on the Motif and release, i.e. the keyboard output goes to silence, the VS-100 loses sync. The display shows it going through the re-sync process and sync is regained in about two seconds.

I haven't had much time to determine if the problem is with the Motif or the VS-100. But there are no postings on motifator.com for this issue and my engineering background tells me that the s/pdif clock recovery on the VS-100 is probably having problems when the datastream goes silent.

Has anyone else seen this?
