Today Microsoft released their DirectX 7.0 SDK.

While the download is rather large at 129Mb, I expect it'll be worth
the wait.
The SDK includes VB examples.
I'm gonna experiment with 3D positioning of wavetable music synthesis, and maybe play with hardware-accelerated 3D graphics.
I expect my CD should be ready for commercial release around the year 2025, when nanomedicine is able to provide self-discipline and a longsought cure to writer's block.
