The TEXTURE program currently supplied for PC systems is a pre-Release 8 version, which includes a new compulsory parameter ('omit') for the Texture Simple function.
Unfortunately this makes it incompatible with existing scripts in Textpack and Tutorial Workshop 2, as well as Soundshaper's Texture-Simple parameter page and presets.
It is expected that these settings will be updated for Release 8, but for now anyone wanting to explore Texture Simple on the PC needs a Release 7.1 version. You can download it at:
https://www.soundshaper.net/downloads/texture71.zip . Unzip and copy texture.exe into your existing CDP programs folder (...\_cdp\_cdprogs). If you want to retain the Rel.8 version, rename it (e.g. to textureR8.exe) before copying the replacement file.
SoundLoom (PC): to see if your version of SoundLoom supports the Release 8 version, go to the parameter page for TEXTURE SIMPLE; if that has provision for the OMIT parameter, then you don't need the older Rel7.1 version, otherwise you do.
CDP MAC software and SoundLoom (MAC): not having a Mac, I don't know what the current situation is. However, you can check the Usage for Texture Simple to see if this includes the OMIT parameter and you can also look for it on the parameter page in SoundLoom (Mac).
