For using Pulsar as a digital patchbay, is there an appreciable latency?
i.e. ADAT ins routed back out to ADAT outs?
Thanks!

What's the latency of the P2 ADAT i/os?

Well, i admit to not having tried it but as it is all hardware so it should be close to nothing.

latency is nearly nothing but there is a module to compenstate for the slight delay.(the module's for mixing.the latency's really not noticable during tracking or overdubs)
latency is about the same as hardware.

as pointed out on yahoogroups, it's hardware to the point the SHARCS do the routing, & then there's obiously some software running. It's a clocked syncronous system, so there's certainly some propogation time, even for the hardware component.
but you guys knew that already ;P

so here's that 'sweet nuthin' in figures:
0.45 ms or 20 samples at 44.1
measured a mono drumbox with left channel original signal,
right channel to mixer adat out, Pulsar adat-in routed directly back to adat-out and returned into adat-in of the mixer.
I recorded the monitor stereo out of the mixer to measure delay between channels.
cheers, Tom
shit, I'm OT, did this on Pulsar one

Astroman:
Your numbers also include the process delay of the mixer !
If you want to measure the Pulsar ports only, send it physically adat out->adat in on Pulsar.

hi Kim,
that same thought came to my mind as well.
But imho the setup comes very close to the patch bay application.
Every device will have a certain amount of these 'micro' delays, so I guess agood patchbay will compensate for it.
For timing of instruments it doesn't matter, but if the same sound is feed back this way there's already frequency exinction, though not yet flanging. With a piano it sounded a bit dull and hollow - not too much but clearly noticable.
Obviously there's a reason for the expensive stuff.
