Well....you are going to need to measure the latency in another converter
soon. I will try to ship it ASAP. I need to test it here first but that
should not take long.. It looks like it is brand new. Very high quality. I
was surprised, though I don't know why. They build great stuff.
I don't expect any problems.

Thanks DJ...
Regarding the email I sent you about Lexicon core 32 can this run alongside
a Pulsar card that uses ASIO drivers ?
I know that the standalone way you have configured it uses the MMIO drivers.
So there might an interesting fact first Scope can recognise the MMIO ins
and outs or connect them with adat optical.
Note that I threw away your scsi drive (man that was so loud !!!11) and installed
the win Me which works with lexicon and DSPFX cards just great.
The concept is that simple...
With a pulsar card a cheap one Pulsar I ( I sold one to Aaron !!) creamware
card that has spdif in/out and 16 adat ins outs can serve as a digital patchbay
for bot c ore 32 and DSPFX cards plus some great Pulsar Reverbs so that this
pc can be an outboard heavy reverb hardware stuff !!

Dimitrios

I don't remember how I had that thing configured........other than I just
ran a couplle of coax and ADAT cables in and out of my MEC and chose what
I/O I wanted to use in the Lexi control panel. I don't remember which ones.
I think there wre something like 8000 different choices.
