Just curious, but is 10 Master verbs good for a PowerPulsar?

Greetings all,

Well after reading a bunch of threads in the archives it seems the standard bench mark around here seems to be masterverbs. I have a 15 DSP PowePulsar in my box which consists of the following:

- Asus A7N8X nForce2
- 512m Crucial CAS2 (normally a gig but I borred some for a 2nd PC atm).
- Athlon XP 2500+

So I decided to load them up and see what I can manage, I ended up with 10 Masterverbs before I got a "Not enough DSP Power" or something to that extent message..

Though while looking at the DSP bar it was only sitting around 70% in terms of how much the yellow bar was in considering a 1-100% ratio..

So is that any good? Just curious is all..

Cheers!

Hmmm, I thought a Powerpulsar would be able to do more Masterverbs than that. They don't take more than one DSP each do they?
You'd probably run into a PCI limit first.

hmm...seems a bit low...

i have a pulsar2, i get 8 masterverbs and 2 notches left on the dsp meter..

probably the Masterverb has to be careful when allocating DSP resources to prevent the device get's distributed over DSP boundaries in a way that phase fidelity suffers.
Like the math remainder in division

just a guess, tom

Can you aditionally load any other SFP devices, besides the 10 Masterverbs?

Well here is a general of whats set up in SFP, though im at work ill do my best to remember

- Mixer: 2446?
- ASIO2 16 Source
- 8x Multi S Effects inserts
- Sequencer Midi Source
- Creamware Midi A
- Analog Source
- Wave Source
- Analog Dest.
- Wave Dest.
- Asio2 Dest.
- 10x MasterVerb

To the best of my recollection that encompases the entire .pro

Cheers!

Hmmh... I got "only" 9 and when trying to add one more, I get
"A capacity limit of your dsp cards has been reached. The specific cause is: Not enough DSP memory: cannot connect PC Master 3k delay.Tap1 and DLEXTM0.RI"

Weird. Maybe something is broken in my card? I've got this DSP memory thing before.

Spoimala,

Which card though? The 15 DSP Pulsar? Maybe Mobo PCI bandwidth has some variance in terms of how many Mverbs can be run on the card..

Who knows lol..

masterverb use is limited by dsps available AND more importantly,pci bandwidth on the mobo.10 is good.the most i've seen is 12 or 13.damn,how many reverbs do you need at one time?

Spoimala, that DSP memory error is most certainly related to the processing of data, and means the specific verb / delay you use produces too much intermediate stuff.
There are only 64 kbyte on-chip cache and the message is pretty clear that this is exhausted

cheers, Tom
