Is there a BNF grammar for the scripting language? I cannot find anything that explains the syntax of this scripting environment, definitions of all the keywords, how to create syntactically and semantically valid "statements" so as to create my own scripts.

For example, what do the following "statements" actually mean and why do they seem to be german style with verbs at the end? Is this a stack-based RPN style (or Forth-like) language?

empty join group 1 listen
tonic to notea set
course 2 offset to 5 interval set



(P.S. I looked through http://www.eigenlabs.com/wiki/The_Belcanto_Introduction/ but frankly it's not really helpful unless you already understand the system deeply)

It would be helpful to have some kind of audio-visual tutorial (I realise there was talk of a Skype-based demo, I'm thinking more like a YouTube video) just to help with getting over the initial hurdles with EigenCommander and Belcanto.

In my case, I rarely manage to get a Belcanto command to actually interpret properly using Belcanto on the Alpha. If I type a command ("sampler 1 hey") in Eigencommander I will get a success return. Frequently trying to key it in via the Alpha yields much more bizarre results, like 2 1 3 5 not being interpreted as "sampler", with varying alternative meanings ("9 3 hey", "2 1 3 5" in red, etc) being given. Verying the speed of the cadence played gives me inconclusive results, although in general what I was trying to type is not what is interpreted.

Although I can type Belcanto commands into EigenCommander, I'd rather be keying cadences via the Alpha.
