Dear Mr. Frank Hund and Creamware devotees,
We need a Creamware sequencer.
What if I were to tell you that there is already a powerful, elegant, sfp-like sequencer sitting unused on the shelves at Microsoft? Well there is such a sequencer and it is called Bars & Pipes Professional.
Microsoft bought a company called The Blue Ribbon Soundworks Ltd. to acquire some of their low level technology. Blue Ribbon itself was not a Microsoft developer. Rather, the company developed for the somewhat Unix-like Amiga and (to a lesser extent) the even more Unix-like Silicon Graphics platforms. The company's premier product - which Microsoft never exploited - was Bars & Pipes Professional (B&P Pro) "a high-end MIDI sequencing and composition package."
On the Amiga, B&P Pro was able to run in conjunction with the SunRize Studio 16 hard disk recording system. (The SunRize Studio 16's AD 516 card was built around an Analog Devices (Pre-SHARC) DSP chip. Bars & Pipes' code understood the Analog Devices chip well enough to be able to sync with it at what I would assume was a pretty low level.)
The graphics of B&P Pro were colorful, though fairly low-res for 2004. The user interface, however, would feel comfortable to any sfp user. The sfp interface is more open and flexible than B&P's, but the general idea of connecting smart icons in a path is pretty much the same.
A native Creamware sfp environment with VDAT and Bars & Pipes Pro would satisfy the needs of many musicians without having to resort to some of the steps we have to take currently if we want to run a sequencer and sfp at the same time. Both sfp and Bars & Pipes Pro are relatively intuitive. Despite their power, they don't get in the way and they don't make the user (or me at least) feel stupid, unlike some sequencers which shall remain nameless

.
Mr. Hund, if adapting B&P Pro to sfp (and Windows and Mac) sounds feasible (remember, it ran on SGI as well as Amiga), I suggest you contact Microsoft and see if they will sell or license the source code and copyrights for Bars & Pipes Professional to Creamware Audio.
At one time, some Amiga developers tried to buy the rights to B&P Pro, but the price Microsoft was asking then (mid 1990s) was much too high. Microsoft had no interest in seeing the Amiga survive, so they would have had little or no incentive to sell to an Amiga developer.
Why would things be different now? Because Creamware is one of the reasons Microsoft is finally being taken seriously in music production. A stronger Creamware platform would reflect favorably on Microsoft. Also, Microsoft's political situation these days may make them more amenable to overcoming a "dog in the manger" image. And of course a number of years have passed since Bars & Pipes Pro was last upgraded (but great code is still great code).
Besides, if Microsoft says no to selling Bars & Pipes Pro at a reasonable price, you could always ask them if they think you should turn to the open-source software community to develop a sequencer, etc.

If such a sequencer wound up looking and responding like Bars & Pipes Pro (I do have the manual), well so much the better.
If you want more information, let me know.
