Ok i still use texture 4.25 and also Texture Live for the gig.
It now runs within Dosbox 0.74, and runs well on win7 ultimate on a laptop, without the need for a physical Mpu 401
I really enjoy the pattern style simplicity, and also use a dos TRS macro application called Superkey.
The midi runs through Loopmidi, and the only problem has been the limit of 50 songs in Texture Live.
The macro app fixed that, loading a new 50 songs at the press of a single F key, so my repertoire of 300 or so is virtually available instantly.
Anyhow it still lives.
Cheers
