Recording digital signal

Hello.

Shortly: How to get digital inputs visible in Cubase Mixer?

Setup:
Pulsar 1
Scope 4
Windows XP
Cubase SX3

I have TC-one (external effect) digitally connected and it works well. So my digital configuration should be ok.
In scope i have 4 channel asio driver (2 for audio and 2 for spdif).
In Cubase device setup all 4 channels are visible, but not in the Connections / Inputs sheet. Digital channels are visible in External FX sheet where I'v made busses for TC-One.


Please help....APUA (as we finns say)

My aim is to record acoustic guitar with stereo mic set up to one track and digital effect signal from TC-one to other.

well, that's really easy to answer...
you simply cannot do it - or better, the Pulsar One cannot do it. :(

it can have an S/PDIF in or out, but not both simultaneously, which your FX box would require.
the easiest (cheapest) way to solve the problem would be to add a 3 DSP card (Luna, Powersampler, Scope Home are just different names for the same item)
make this one Scope's main 'communication' card and use it's IOs

4 DSPs isn't a lot anyway, so the processing extension may be welcome for other reasons, too.
Of course you can also add a 6 or 14 DSP card, (a very attractive way to get both the Mix&Master and Syth&Sampler packages for a bargain), but generally the 3 DSP cards sell cheapest - even for 100 Euro on EBay.

cheers, Tom
btw. I have 3 of those 4 DSP cards ;)

Thanx astroman for bad news;)
God news is that this can be easily solved....hope.
One thing I don't understand in you reply
it can have an S/PDIF in or out, but not both simultaneously, which your FX box would require.
I can get the external box to work so spdif goes out and returns. So your point about spdif here can't be right...right?

I didn't mean the TC box, but the Sfp project.
Cubase doesn't matter in this context because it only 'sees' what is in your Sfp project.

you may try the following, but for simplicity don't start Cubase.

connect Pulsar S/PDIF Out --> TC In TC Out --> Pulsar S/PDIF In
set Pulsar as digital clock master and the TC as Slave
then (in the project window) route a synth's output to S/PDIF Destination

when playing the synth, you probably see activity at the TC box
you'd expect the return from the external processor at Pulsar's S/PDIF Source (in the routing window)
most likely this will not arrive
(instead of the synth any signal will do)

cheers, Tom

Okay...I did it and your right. No signal back when pulsar is Master. But when as Slave the signal returns so I wonder could there still be some work around to record digital signal with only one Pulsar 1 card?

sound can go EITHER in OR out of s/pdif on a pulsar1. you can record via s/pdif, no problem, you just can't make a loop. a second generation card(pulsar2, luna, powerpulsar, scope pro, project, home) CAN do an s/pdif loop (in AND out).

period.

it's just how the cards are made...... :D

there's no way to get the s/pdif module to show up in cubase in scope mode, however. the asio modules ARE cubase's jacks, if you think of cubase as a piece of hardware, a recorder, which needs jacks to connect to a mixer or amplifier. connect the s/pdif module to a mixer which sends to the asio module OR directly to the module.

the reason i mentioned a mixer, is that you can connect your monitors to this mixer(the stm2448 has a control room out) and listen to your inputs and cubse through that mixer(rather than listening through cubase), this gives you ZERO latency mixing and monitoring, and unlimited routing. nice.

if you are using xtc mode, then the s/pdif modules should show up in cubase as i/o options. try running the i/o enabler in the scope entry of the start menu, or in the scope folder.

sorry, for giving you info that you may already know, i hope something helps....
