Mine is finally completed, calibrated, tested.

Here are some sound clips:

1) The basic sampling of those famous 259 sounds. I switch different kinds of modulation and change the frequencies of both oscs. I twist mod index and all the different settings on the wavefolder. There's nothing but the 259 and its raw output going on here.

At 4:17, I add cross synchronization. Of course, you could go on for days with all this. I decided to stop the clip and do some more organized sounds to give people an idea of what a 259 actually does.

2) There is a lot of confusion about what the Symmetry system does on this synth. Here you can hear the Symmetry Control go from all even harmonics, though a saw-ish waveform, to all odd harmonics. Many harmonically rich "plain" waveforms exist between these settings.

Order and Timbre at 100%

3) Timbre control at 100% so you can hear what "order" does. It fades from the plain waveform (Symmetry Control) to the wavefolded waveform. If you set Timbre at 0%, you are always getting a low harmonic waveform (sine). Check the panel of a music easel and you will see this labelled pretty well.

Order swept with Sym at 50 ("Saw" like) then at 100 ("odd") then at 0 ("even") then at 50 again.

4) This is the Timbre sweep of the raw waveform from Symmetry control. Very nice for simple synth sounds fading from a sine into a high harmonic waveform. So, with The wavefolder mix set to 0%, Timbre will simply sweep from a sine to a wave like a square or a wave like a saw. Again, see the music easel for a bit more clarity on this.

Sym 50 ("Saw" like) Sym 100 ("Odd") Sym 0 ("Even") and then Sym back to 50.

5) Symmetry is at 50% (Saw-like wave).

First sweep, order is "High" so you get the plain waveform. Second Sweep, order is at 50% so you get a mixture between the plain wave and the wavefolder. Third Sweep, Order is "low" so everything is wavefolder. So, order controls mix between raw clean waves and folded waves.

I hope this clears up any confusion about what these controls actually do. I have seen a lot of odd theories throughout the years.

A lot of people want to hear some sequences and tweaking or EG applied to different parts, so I have a step sequencer on the way. I should have those sounds up in a week or so.

Other than a 3-digit number, what is a 259? Is it a chip? Software? Hardware? I tried googling 259 but that was no help at all. Just wondering.

It's a very rare vintage Buchla synthesizer Module. We can talk about it like a "303," but it's easy for us Buchloids to forget that not everyone is as into this type of modular as we are.

Thanks for the explanation, phdinfunk. Thanks for the link, elmegil. I am now elightened!

BTW, I just googled 303 and Roland TB-303 was the 3rd item in the search list. I think I looked on 3 pages when I google 259. The Buchla was not listed.

Anyhow, it looks like a handy module.
