(it was on Ableton forums so I assume it's public knowledge).

Looks like I've got to hold out 'til Urs unleashes VST.

I look forward to hearing this. When quad core CPUs are affordable it might just become a viable option.

Isn't Z2 singlethreaded? I don't think it can take advantage by splitting the load over multiple cores/cpus.

At least, it hasn't been thus far in Cubase 4 with 'Multi Processing' enabled on my dual-core system.

Multiple Z2's maybe, but not like different instances can link to each other...

As long as any single CPU heavy (e.g. big unison) part doesn't need more than a single CPU core then it shouldn't be an issue.
I would love to see a native synth genuinely giving DSP powered or external synths some real competition.

My snippet above takes like 30% max on a P4 2.8 (with energyXT2 beta which is probably not very efficient in itself). (If I recall right.)

A Core 2 Duo would be much faster... And multiple instances on multiple cores of course - it's not THAT intesive

I've publicly shelled out the beta for Mac because I wasn't sure how it performs on pre-Intel Macs. The Win version has the same state...

... all that needs to be done is tuning the filter for samplerates other than 44.1kHz... which... as I just fetched my FireFace800 from my local dealer... bought it for the very purpose of having more samplerates... soon

Urs

P.S.: Maybe not that soon, because I just had some more ideas to make this filter ultimatively more flexible...

You filter whore!

If you're a mac user, grab a RAX demo and check out Urs' beta.

I use Tracktion, which is VST only ( at the moment ), but like to keep
RAX around for times like this.

I'm pacing in circles waiting... very excited about the update.

It is a viable option now. The XMF filter is a beast and it works fine on my G5

Silly question. Cross Modulation Filter (XMF) sounds wonderful, but I'm a little sketchy on the terms. What exactly does it DO, simply?

I mean, lowpass -- increasingly attenuates frequencies above a threshold based on a configurable 'slope' <insert fancy graphic here>

How can XMF be summarized, and it isn't a "Z2" thing, it can't be -- can it? I mean, the concept and implementation was done -- where else?

Urs strikes me as someone to put in known, cool things, not go all 'mathemetician' and invent brand new, complex filtering algorithms from scratch... unless I'm wrong?

It's called cross modulation filter because it has a side chain input that can be used to modulate the cutoff frequency i.e. by an oscillator. This is widely known as FilterFM and allows for some really great effects. Back in the analogue days it was often used to create voice-like sounds. Or, simply listen to Oxygene Part II for some bubbly sound effects made with FilterFM.

Other than that it currently features 4 pole lowpass and bandpass modes. But it isn't limited to that, I might just put in all 15 filter modes of the Matrix 12. Its circuit diagram is just pretty weird to look at, so I'm not sure if I can suss them out quickly.

Sounds cool, Urs... I can't wait to try it.

Everyone else; thanks for commenting on the tune. It IS a video game remix so, yeah, I can understand any criticism on that front. Though personally, I love video game music.
