Helix Rack S/PDIF Sync Issues

Recommended Posts

Helix Floor and Scarlett 18i20 - SPDIF works fine.

Simple RCA SPDIF cable connections.

Internal, 48k.

Helix can be set to send or receive MIDI Clock.

Not something I normally use, but with RECEIVE MIDI CLOCK set to AUTO I have synced it to follow tempo from Reaper.

I also used it to control DAW Tempo with EZDrummer. Both of these were just experiments to see if it worked and TBH, I only did it once, long ago.

Only noises I ever got with this rig was when I tried to use a really low buffer setting (<64) when using Helix with plugins.

Need a better computer to go <64, but 7.6ms latency works fine for me (Scarlett as AI, Helix as AI 12.6ms).

That's about all I know, like I said, not something I really use.

I'm not sure midi clock has anything to do with word clock/digital sync.

It should be possible to get s/pdif working without clicks without having any midi connection whatsoever, surely?

 

 

 

 

I have no noises with my setup, simple RCA SPDIF as described. I don't even really know what "word clock" is for.

 

I just looked it up:

 

Word clock and MIDI interfaces. - InSync (sweetwater.com)

 

Seems like more stable, less strain on CPU. Like, if you're depending on controlling Helix from DAW for live performance it would be useful?

 

It does seem like it's an either/or thing - BNC vs RCA, so maybe using both is causing your noise problem?

Just spitballing here while we wait for someone who knows what they're talking about to chime in!
