Just wanted to share what I'm working on.
This is a csound server (using the Python API) with a web interface via 
Flask. A SQLite database contains templates and instruments.

A template is basically an initial csd file that can contain UDO's in 
instrument 0, and generic instruments like mixers.
This template is a 4 channel mixer with effects and panning per 
instrument. 2 instruments are currently loaded.
A test button per track plays a specific short score for the instrument. 
An overall test button plays all the scores in all tracks.
The 'detail' button brings up specific detail sliders for the 
instrument, in this case for the filter settings...
