Another bizarre thing happening here with the newest beta, Urs. With some of the HH patches from the Virus challenge, I get a mosquito pitched buzz panning between the speakers with no apparent cause for it. Try for example V-Pad 4 in the Virus factory preset bank to see what I mean.

Dude, that's a bug in the Reverb... some compiler issue that needed a code update... fixed in

Choose a wavetable that has peaks in it - i.e. islands of rich harmonic goodness surrounded by low lying areas with few harmonics. Modulate the wavetable position so that it's mostly in the low harmonic region but occasionally pops into the high region. Now, start playing with the oscillator effects

pfft, hard for these old folks to keep up.

The last ZIP Urs posted (with the waves arranged into wavetables) is working fine for me, and boy, is it ever cool to have these. Having used a lot of this same wave content in the PPG and being used to modulating wavetable position with evelopes, LFO's, modwheel, etc, it puts me back in familiar territory and has finally drawn me into messing with patch creation in Z2. I had something similar to that classic PPG "analog pad with a touch of digital air on top" that Patrick O'Hearn used so much within a few minutes of messing with these. And these waves sound cleaner in Zebra because of the superior pitch shifting...you don't get that wash of aliasing on the upper registers like on the original PPG (which my old Prophet VS also suffered from).

Thanks so much for making these available. Let the creation of "Wolfgang Palm on Steroids" sound sets commence!

Vectorman, you've hit the nail squarely on the head - that's exactly why I did this. Evolution, not necrophilia

'kay, it's all done. I've got 300 ppg/mw waves and 94 prophet vs waves in z2 osc format. I spent the evening doing some direct comparisons with the originals and I think those of you who care about such things are going to be happy.

These sound great! Many thanks, and hats off to you, sir!

Thanks for the VS and XT waves, chaps

However, I don't remember some of them being quite so buzzy in the original instruments. I compared the VS waves with the ones in Augur (unpolished but interesting freeware by Antti). Maybe the lowest and/or highest partials sometimes have the wrong value e.g. due to the reduction (to 128 byte) process?

BTW: I'd MUCH prefer a SpectroBlend version of WavToZ2 (taming the upper partials would then be easy). Or Zebra itself should resynthesize edited GeoBlend data and automatically copy to SpectroBlend? Could be the way to go eventually.

Anyone here "do" resynthesis?

Interesting. I already do FFT/iFFT so in theory that should be easily fixed but...........

There's a couple of issues. I never got the FFT/iFFT working 100 % correctly so instead of 128 harmonics i settled for 96 (i think.Have to check the source for that) so it would be noticable in a whole other way than it is right now. Never heard anyone complained so far. I could of course do an intermideate version with 96 harmonics 'til i find the bug and then update.

The next thing is i really should be doing other stuff right now so i'll be a bit pressed for time in the next 2-3 weeks. However i know myself well enough that i'll probably talk myself into doing this instead. I'm easy that way.

"What are you doing ? You should be doing that other stuff you know"
"Well i was'nt doing that other stuff anyways and i thought it was better to do something than nothing"
"Ok fair enough.You do have a point there"



If you have'nt heard anything about it before September give me a nag.I need a kick in the nads from time til time.

I compared the xt waves with the z2 ones and they're very similar sounding. As far as the vs waves go, the originals were 12 bit and so I guess it's possible I made a mistake in the conversion. However, I did do a visual inspection (I have a pdf somewhere that has pictures of the vs waves) and they looked similar enough for me to be reasonably sure that the conversion was accurate. I'll investigate further when I get a chance (which might not be for a while, unfortunately).

Dave Smith (re)used the vs wave bank for the evolver so if you (or anyone else) have an evolver you could use this as a pretty definitive comparison...

thanks, Suthnear!

Ah no - if just one value is significantly off, e.g. the one on the far left or far right, you'll get quite a buzz on otherwise pure sounds. You can hear this effect for yourself by carefully editing just the left or right value of a GeoBlend sine wave.

True, but this is easily seen from the geoblend waveform display. Last night I checked the first few waves - sine, saw and square - and they all sound as I'd expect them to. Since the process that created them created all the others (it's just a data transform from 12 bit integers to floats), if there was a bug in the process, it would show clearly here (particularly with the sine wave as you point out). So I think that the data is probably ok. However, as an imperfect being, I can't expect greater perfection from what I create and I'm happy to fix my mistakes. I'm going away for a few days but if you'd like to pick a few waves that you find egregious and post their numbers here, I'll have a careful look at the original data when I return and see if something is going wrong.

Big pimpin time. You are aware of my wav2Zebra2 converter right ?
http://www.tekno.chalmers.se/~magolo/sy ... Zebra2.zip
I've just uploaded a new version that exports all 16 waves instead of just 12 as it used to.

Freaking excellent! I have never noticed this application before, but it really kicks ass.
