there is no need to verify anything - you can do it yourself.
Load a Minimax, set it to max # of voices, this should fill a significant amount of your dsps.
if it didn't fill dsp #9 load another instance, set to a high voice count
did it break on #9 ? probably not :wink:

set one instance of minimax to a # of voices that fill (say) 8 dsps.
according to your hypothesis the next masterverb pro will break on the memory of chip #9
did it break ? I bet not...

btw Masterverb Pro's don't count for benchmarking - use Masterverbs instead to receive comparable results - MV Pro is an optional device.
I guess it's significantly more demanding, so your 7 instances are probably very good.

regarding the logic:
reverbs are built from delay lines
delay lines need memory - some on chip, some over the PCI bus
both resources are limited

you'll never need that much instances of a top reverb - it's simply a waste of resources.
No human ear will be able to distinguish them in a production - in other words: you could achieve the same result with less demanding devices.

there's the solo singer and the background vocals - the solo Stradivarious and the violin section. There is a reason to isolate the 'better' performer :wink:

What I'm looking for here is a positive way to determine if a Scope Pro board is operating correctly.

Ideally there would be some kind of utility program that you could run to test a board. Since I don't have that, I'm asking if any other Scope owners could run the test.

That's cool if not. Just trying to establish whether the hardware is malfunctioning...

the procedure above WILL verify that YOUR board is ok - the Masterverb Pro test doesn't apply at all because it's bound for a system error in any case. That error message isn't uncommon in context with reverbs...

over, Tom

Phew. I feel better.

All this started when I was trying to figure out what the "MasterVerb Test" was... I still don't know...

But I'll go back to being Bobby McFerren now, and not worry... Thanks for the feedback.

:grin:
the "masterverb test" is the benchmark of pci performance of a motherboard with a scope system running. anything between 7 and 10 is considered pretty good. in real life, that would be some pretty extreme use of reverb. most STUDIO mixers only had TWO auxilleries 30 years ago and even 20 years ago four auxs was pretty good. pretty good? it was plenty. some pretty crazy stuff was done with a lot less than we deal with today. (i know that anyone named ScofieldKid doesn't really need to be told that, nothing personal in the rant...)
