Oh God, I hate the search on this site. I know I wrote how to do it somewhere, but I'll be damned if I can find it after 20 minutes of searching. I think you just need to put it into a folder under the Data folder. Crappy instructions, but I'm spitting blood after trying feverishly to find the instructions that I KNOW I posted somewhere on this damn site! :x

George, this is not Wusikstation propaganda. If it is, your page is propaganda to SFZ, as it shows a non real-time graphic right on the top. But don't take it the wrong way ok? I'm just pointing something up.
What non real-time graphic on the top? Djeez, don't tell me you understood that bad too...

stefancrs, I did notice your post, but didn't get the proposed method that's why I didn't comment.

This is the result I got on a P3 1.1Ghz laptop, 256MB RAM, Windows XP SP1, playing a 4 note chord each and nothing else. Both are using "draft" mode and Buzz / Polac is hosting them. Anyone is welcome to redo this (still pointless IMO) CPU thing.

So, I'd like WilliamK to do a few things: remove his cpu measure post/edit in page 1 of this topic :roll: and remove his statement about "the fastest engine on the market" since it is not considered a true fact anymore.

I was told how to load a wave in this thread, but I don't remember on which page was, sorry :oops:

IIRC you need to put a subfolder including the wave/s in the preset folders location.

Ok, I removed all my post, as I see that there is no way I can debate over George and Rene here. :(

Edit: Also, where is Jeskola? I can't find a VST version. Testing on Buzz? 4 notes? :roll: Ohhh George, try testing 32 to 128 notes. :?

I'm out of here.

Wusikstation is still one of the fastest engines on the market. I never said that there are no other engines out there that would perform good too. But once you start adding filters, effects, envelopes, etc... we still got the best performance. "Prove it!" I don't need to prove, and I don't care to prove, as everybody is seeing that and praising that my code is fast. :lol:

BUT, I was not making any propaganda about the software, as this post is being read mostly by developers anyway. Since Arguru did some incredible help to me, and also, even George pushed me on doing the Hermite Interpolation. I was trying to say that there are ways to do "good" interpolation while keeping the code fast, if you use SSE in paralel. But who cares? I guess nobody cares...

Sorry guys (George and Rene), but there is no talking with you.

Not my best regards, WilliamK

Damn. Fun is over then.
Good luck to your fast code in Beijing 2008.

www.jeskola.net then XS-1 and download VST version. Also, why would you like results over 32 or 128 notes? Isn't almost 50% fastest over 4 notes enough?

Wusikstation is still one of the fastest engines on the market.
It seems you have already changed this statement, however, I'd ask you to contact with your supporter sicklecell666 since he hasn't edited your group buy product features :D Check http://www.kvr-vst.com/forum/viewtopic.php?p=689409

Better change that before someone sues you for false statement ;)

I don't see why you are asking about making further comparisons, specially when you will be getting a clear disavantage from any speed, aliasing or anything with Jeskola XS-1 :P

But let's forget this odd issue, we are sorry to lose a relevant developer like William in this discussion but let's focus again on the fascinating aliasing subject:
stefancrs wrote:What about "converting" the sample to contain the integrated value (per sample) instead of the current value (per sample)? Then one could calculate those integrated values with high precision and then downsample from "infinite" oversampling using a box filter (since you'd just take the average of the output since the last output sample). Ofcourse reading from the sample would use interpolation of some sort, and with some oversampling as well one could probably reduce the aliasing that occurs due to using box filtering...

Thanks pough. I failed tho. Also, how do you make Wusikstation play 128 voices?

You'd better hope so.

George, I'm being nice, as I really don't want to do a flame-war here. I won't change, as it IS true. I tested Jeskola here and is not faster than Wusikstation. Sorry, I guess you just tested the wrong way. Anyway, I won't discuss this anymore, as you are the owner of rights here, you are the master, God of coding... hummmm, but what have you ever coded anyway? :roll:

Sorry everybody that you had to see the "dark" side of me. I won't edit my messages anymore. George is the only person here that is not able to talk in a nice way. I tried to make a point of my own believes, and this is what I get...

Is detailed on the User Manual found over our site. Just create a directory named "WAV something" and put your WAV files inside. Or you can also use aWave (check our forum and site) to convert your files, or even the free conversion tool avaliable over our site.

Each layer of our synth has its own envelope and voice manager. So you get 4 x 16, and also, the W1 and W2 layers plays 2 voices per key. So is 8 x 16 = 128 voices. And that's it. We will also release a version that will output each layer on its own midi-channel and stereo-out. (multi-timbral) As some users requested.

Screenshot? Proof? Anything? At least I bothered to post a screenshot...

george, WS runs faster here (running as a pure rompler) given both tracktion, sawstudio and windows CPU meters.... OC'd 3.6 p4

Can you tell me which meter you're using?
