[gst-devel] a GstType for a musical note

[Stefan Kost]

Hi,

can't the scale be part of the GValue ? The downside is that this means doing 
the table lookup everytime one wants to read from the value. And its needs 
convinience api. The advantage would be that apps would know that this is the 
property they should feed musical notes into.

Heres a first link to infos about scales:
http://en.wikipedia.org/wiki/Scale_%28music%29

I'll do some reasearch during the next days to find out about how other 
plugin-apis handle that.
