Hi all,

Since it looks as if Urs has fixed the 16 slot oscillator loading bug I'm now going to convert all the microwave xt wavetables to z2 oscillators. However, I can't just convert the wavetables themselves - they often have more than 16 waves. I'll definitely convert all the individual waveshapes from the xt's wavebank and bang them into z2 tables 16 at a time. There are 100s of them so this will mean many, many new oscillators. This is how I converted the prophet vs waveshapes to z2. However, there is not necessarily a relationship between contiguous waves in the wavebank. Relationships are handled by the wavetables which group individual waveshapes (wavetables are just a set of pointers into the wavebank) . So sweeping z2's table may lead to discontinuities. Also, since there's no way to copy individual waves between oscillators, it'll be tricky to build up your own wavetables using the sounds.

I'll try and create z2 versions of the wavetables themselves - i.e. pick the most characteristic waves in a wavetable and rebuild the wavetable itself as a z2 oscillator (using z2's interpolation where necessary). For the wavetables with 16 waves or fewer this will be trivial. However, for the tables with more than 16 waves, this will be manual and therefore will take some time. Any other suggestions for this?

Also, I don't have any web space - can anyone recommend a decent hassle free hosting service. As noted, I also have the prophet vs waves...

Here's some web storage space for free. Good luck with the project.

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.

It actually works on the same principle as the Waldorf Waves does. It uses FFT/iFFT to fill in the blanks so to speak. I've since discovered that Zebra2 can do this on it's own but hey,you can't know everything,right ?

I'm pretty sure the Waldorf's waves are just made from a few starting waves and the rest of the table is constructed with the method described above. So in theory it should work fine to do as you planned.Just import the important ones and interpolate the rest. My program makes sure there's no discontinuities so that should'nt be a problem and i'm sure the waves are made that way to start with so even less problems.

Great! Latest beta version required though:

http://www.u-he.com/Zebra22b4Win.zip Beta 4 for Win

http://www.u-he.com/Zebra22b1AU.zip Beta 1 for AU will do

(beta2-beta4 were Win specific fixes)

Enjoy,

Urs

I've added some warnings. The new one is in a folder called "Warning you need the latest Zebra2 with this" together with a text file called "It will crash Zebra2 unless you use the latest version.txt" that states you need 22b4 to run.

I'm sure someone will ignore that and use it anyways but it was the best i could do without actually scanning the HD to make sure there's no older version of Z2 on it. And i found that a little overkill.

Yeah, I've got that. Handy tool, thanks. But I'm not working with audio - I've got the waves (and wavetables) as sysex, so no fft required. I've already written the code to turn the sysex into z2 scipt format, all that is required now is a bit of organisation of the results. I'm going to try and do it this weekend.

fwiw, I was astonished by how close z2 came to both the microwave and the xt when using the right waves. The only thing z2 can't do is wavetable to wavetable fm, surely the xt's single nicest feature (for me, nyway)

p.s. that last line should be read as a broad hint, Urs

Got that! Give it a couple of years until cpus are fast enough to do a couple fo FFTs within the osc along with OscFX, supersaw *and* FM driven by external source

Since all of the microwave 2's sound processing is handled by a single, antiquated dsp (motorola, AFAIR) chip, it's unlikely that its implementation of fm would be particularly complex. Or are you saying that it's all the additional stuff you've implemented that makes it difficult in the context of z2?

I'm definitely looking forward to having that wave content available. One of the reasons I found Zebra in the first place was because my PPG 2.V was starting to feel a little tired and I wanted something that employed the wavetable concept with a more powerful voice architecture - this is right up my alley. Being able to reproduce some of the classic Prophet VS sounds like "Voices" and "Acid Rain" and then further manipulate them with Z2 should be a lot of fun too.

Just to clarify...is updating to the latest Z2 beta only required for the process of getting those waves into Z2 format, or will we need the latest beta to load those wavetables into Z2 as well when they become available?

The release of V2.2 is pretty imminent... just 2-3 more minor issues... free update of course...

You only need the beta to load OSC presets created by jupiter8's tool. If it's then saved again from within Zebra, it'll load just fine in any version of zebra.

)

jk about the wife thing BTW!!
