I read a review of the Pulsar Suite in last month's 'Sound on Sound'. They pretty much wet themselves raving on about it.
As to whether it's worth getting, well, it depends on what you want to do! It's quite a pricey item. If all you want is to record audio digitally, you're probably better off buying a straight audio card. Throw the surplus cash (!) at mics, pres, a good compressor, decent nearfields and a pretty headstone for your early grave when the wife finds out.
The pulsar has good D/A converters, 20 inputs and 20 outs, only two (1 stereo in, one out) are analogue the rest are digital of various flavours (Do you have an ADAT?).
There's DSPFX onboard (ie: it won't eat up your computer's cpu); EQs, delays, reverbs etc on each virtual channel.
There's an AKAI-compatible sampler, an 'analogue' modular synth and a huge blue virtual mixer that takes ages to load up on a PIII-500.
So, it's worth it if you want all those features on one card. But unless you're just mixing electronica, there's a load of other stuff you might want to consider first.
If you've got all the rest of the kit and still need a pulsar; go on, get one (but can I borrow your Porsche?)
