Mobius 1.1 out now - 19th June 2000

Mobius 1.1 has been released. It now includes Yamaha A4k/A5k support, preliminary Akai S5k/S6k support, and many optimisations and bug fixes. Registered users may use the auto update feature to install it, and a demo should be out this week!

We've also been experimenting with DSP (Digital Signal Processing), and have come up with a VST filter / distortion plugin. You can read more here.

General Updates - 29th May

Just a quick update on what we've been up to! WaveSurgeon 2.8 is going nicely, and Mobius 1.1 is nearly ready for release. Both versions add support for the Yamaha A4k/A5k and Akai S5k/S6k samplers, and the Mobius update will cure some of the problems users have had. The Mobius update should be out in a week or two, whilst the WaveSurgeon update should be about 2 weeks, hopefully.

New demos will be up soon(ish). Also, apologies to anyone ordering our products who was affected by problems with my registration service - it should all be working now!

Offer extended- 1st May 2000

The special upgrade offer of $29/$49 for owners of Advanced and Basic copies of WaveSurgeon prior to the release of Mobius has been extended to the 21st of May! Hurry while the offer lasts.

MusikMesse - 16th April 2000

Last week saw us go to the MusikMesse, and we've just returned having met many new faces, shamelessly plugged to journalists, and received plenty of new ideas!

Möbius released - 28th March 2000

At last, version 1.0 of Möbius is released today (the delay was for beta testing to ensure all of the nasties were out!). You can read about it here, check out the demo here, or buy it here.

Welcome to - 1st March 2000

As a result of developing Möbius, we've moved some of our site over to This allows us to develop new products whilst retaining the fantastic reputation (I hope!) we've built up with WaveSurgeon. will still be actively maintained, though!

The Square Circle SETI group- 1st March 2000

I mentioned this on the forum, and it's part of our new projects section. To use our CPU cycles usefully while we aren't working, we run the SETI@Home screensaver in the background, to aid in the quest for extra terrestrial intelligence. To this end, the Square Circle SETI group has been set up, and you can join up, should you so desire. I reckon most of you will be too busy running intensive plugins, however, to partake! Still, if you want to join, click here.

More news - 22 December 1999

Just to let you know we've changed our ordering service to try to improve the service you receive (there are now European and U.S. phone, fax, and mail addresses). Essentially, if you have an old demo (actually, this even applies to the current demo) and the ordering info is different, don't worry! And that's about it... Merry Christmas!

Site update #2 (inspired title or what?) - 11 December 1999

Now that all day free net access is available in the UK (well, at the weekends anyway, if you know where to look), the site has been updated a bit more, specifically with the addition of user forums. I'm not sure how well this will work, but a few users have been requesting this, so I thought given our speedy new server, I'd try it. No bad language please! It's intended for people to pass hints and tips on to each other, and provide a bit more of a community for WaveSurgeon. If you have anything to say, click the forums button. I've also updated the tech support docs with a note on SCSI and samplers, and how to get them working.

Site update- 5 December 1999

20 days to Christmas... wonder if I'll get that iMac this year?

As you may have noticed, the site has been rejigged somewhat. A new search engine is installed, with a few other useful scripts. Perhaps the biggest change is that I've changed the way in which tech support is provided, so that you have to enter details about yourself and your problem when you email us. There is only so much development time, and it is soon cut short by emails asking for help without including customer information or system details. This change should mean that more information is provided, and tech problems are solved sooner. Check out the new support page here.

All this should be helped by the new server the site is on, which is reportedly very fast indeed. Incidentally, we also have up and running...

Version 2.72 is also complete. This is an advanced version only, which patches a few bugs with DirectX plugins + improves stability. Check for an update on the download page soon.

Stay tuned - 26th November 1999

New bug fixes and features on the way. Coming soon...

Hosting problems- 25th November 1999

In a bid to improve server uptime and download speed, I transferred to last Friday. There are serious bandwidth issues on their server by their admission (up until Thursday when I retransferred) as you may have noticed. They promised repeatedly to fix this issue (first it was Friday, then Sunday, then Monday, then Tuesday, then Wednesday), but the server was often failing to let users download files, so I've moved again to I've tried the two different hosts while downloading this. CI Host's server shifted 7% of a 1.5mb file in the time it took to download the whole thing from pair. I couldn't even check my email, as the server could not be found. CIHost are refusing to refund the setup fee.

UPDATE: This beggars belief. Part of the legal contract you have to sign to get your money back states that you agree to pay them the costs of defending a charge back on the credit card should it occur. I've spoken to ex clients who live in fear of a lawsuit for criticising this company.

VERSION 2.7 RELEASED - 13th November 1999

At last, version 2.7 has been released. We apologise for the delay, but it has taken months of testing and improvements to ensure that it runs as smoothly as possible. New customers will automatically receive the new version when they order; old customers will be able to dowload an updater, available in a few days.

For more information on version 2.7, see the main page.
