7, 14 and 15 DSP cards. some questions.

Ok i have these 2 scope cards and a pulsar2.

at the moment i am just using the pulsar, while i wait for new motherboard with enough PCI slots.

Scope 1. 15 DSP, onboard RAM 1ADAT, 1 Zlink, Midi, analog.

Scope 2 14 DSP no RAM no I/O

Pulsar 2 7 DSP, onboard ram 2 ADAT, MIDI, analog. 2 STDM

question 1: will having the main I/O i use (2xADAT on pulsar > a16 ultra) be a problem because it can only have 2 STDM to the rest of the system or should i swap the plate with the one on the 15DSP for less traffic on the STDM? there are quite a few input and output to effects going to be in a standard project.

question 2: does the memory get used effectively, and how much is there, (for some reason i think i remember it being 32 MB) for example if i have a delay that uses more than the memory on the first card, is it smart enough to start using the other cards memory or does it straight away go to PCI > main mem.

sorry for all the noobish questions, i want to make the system as good as it can be with what i have. I am looking forward to having the best sounding DSP system again! this time i am even dedicating a room to my "dsp studio"

edit: another question can i still get a plate to put on the other card that has 2x adat and 2x midi instead of zlink? or is that for the "pro" cards with balanced outs.(this one is RCA)

the only i/o plate that had 2x midi was the 24adat(adat only and hard to find).

i would put the other i/o plate on the 14dsp card, just because i like to have everything on the big cards first(generally works a little better).

no, i don't think the onboard memory really doesn much...

hey I always that all cards have just 14 dsp + 1 dsp for controlling the other.

so there really are two types ?

14 and 15dsp

+ memory and no memory....

thats interesting.

yeah the actual real "14" has an empty part on the circuit board where a sharc and 4 RAM chips are on the "15"

(i just noticed the scope 15 card has RAM chips on both sides, total of 4, the pulsar has 2)

so pulsar 2 has ram, 2 chips some scope have 4 chips and some have none and the ones who have none also have a SHARC taken off, which probably runs the RAM in the background.

so i can just move the plate from one card to the other and the software will know whats what?

yes.

your saved projects will be a little screwed up though(fixable by loading the correct i/o).....
