2016-02-03 Sorry for the lack of updates... Yes, I'm still around and all the items are still available!
2010-01-11

The new pricing for narrow-body CEM3396 chips is now in effect.

2010-01-07 Sourcing narrow-body CEM3396's is getting increasingly difficult. Unfortunately this means that I have to raise the price on these parts. Beginning Monday January 11, the price will be the same as for the wide-body chips (€16 EUR or $24 USD per chip).
2009-10-25

I have been lucky enough to get my hands on a batch of wide-body CEM3396 chips that are used in the Matrix 6 and 6R among other synths! These are now available for order in the web shop!

2009-10-25 The long-sought MS6 schematics are now finally available on the downloads page!
2008-08-14

Adjusted the USD prices, according to the current exchange rates.

2006-11-19 Added replacement RAM backup batteries to the offered web shop items.
2005-09-13

If you need more than a few CEM3396 chips, I now offer 6 pieces for the price of 5!

2005-09-12 OK, the new web shop is up. I now use PayPal for processing all payments (you can still pay using credit/debit cards). Check it out!
2005-09-05

By popular request, payments through PayPal will be supported shortly directly on the site. In the meantime, e-mail me if you would like to place an order and pay using PayPal.

2005-01-24 Added Vintage Planet to the links page, and put some more sales flyers on the downloads page.
2004-08-04

I was mistakenly calling the MS6 a hybrid synthesizer on the specs page, now corrected (thanks go to Abbe for pointing it out).

2004-05-20 Removed the bulletin board from the menu, since I have been unable to get it to work. Will add it back when it's ready..
2004-05-20 The site is up again , after another period of downtime. Should be a lot more stable now, since it's running on a brand new server. Let's keep our fingers crossed!
2003-12-24

Merry Christmas! Added a scanned flyer to the Downloads page. New testimony has been added to the Firmware Upgrade page.

2003-11-07 Added a new image to the Picture Gallery page, showing the different designs of the front panel.
2003-07-26

Web site is now up again, has been offline for some time due to serious hardware problems - sorry about that! The bulletin board is still broken, will try to fix it ASAP.

2003-02-04 A slightly updated version of MS6ed is "in the works". Will support the new features of the v1.3 firmware, as well as "vanilla" machines. Stay tuned!
2003-02-04

Hello everybody! It's been a while, sorry about that!

2002-03-25 I've now come across a limited number of Curtis CEM3396 voice chips that I'm offering for sale! More info can be found on the firmware upgrade page!
2002-02-21

Unfortunately, it seems like Synthesis Technology no longer sells CEM3396 chips, so I've updated the info on the links page. I am currently looking for other sources.

I've now also put in mono mode and done some further refinement to the portamento implementation. As usual, see the development page.

2002-01-25 Portamento done! Quite probably the last feature to be included in the upcoming v1.3.

2002-01-07
