I've updated the demos to work with the changes to Gens. Also I've fixed an error with the definition of GEN07 in both Ochre and Majalan.

Copperbox revision 2941.

I've updated the gens modules in Majalan so they follow their corresponding modules in Ochre. Also Majalan now directly depends on Ochre so it can use the strict pair.

I've added some syntax sugar for binding top level orchestra variables - top level variables don't synthesize their name instead it has to be supplied as a string, this is clumsy but it generates better Csound code. I've implemented an idiom with my pair constructor that gives this a pleasant enough syntax.

I've also put the low level gen table wrappers in a module Language.GensRaw  - and started implementing some higher level wrappers.

I've updated the FM demo in OM-Shell to use an orchestra ftgen table. Also I've added more table wrappers to Ochre.

The Ochre Gen modules now have a name clash with Majalan - because they use different symbolic representations for their DSLs the code cannot be shared.

I've added the ability to define gentables in orchestras - Csound has had the ftgen opcode to do this for quite some time, but because it isn't covered in the Csound book I've overlooked it.

I've changed the module organization in Ochre moving the strict pair from Language.Envelope (now deleted) to Language.Prim. The instruments that used the old envelope notation in OM-Shell have been updated to use the new list-and-strict-pair style.

Copperbox revision 2936.

I've implemented a new notation for envelopes that uses standard lists and novel strict pairs.

envelope1 :: IFloat -> GenKSig
envelope1 idur = expseg                    0.01 
                        [ 0.002        ::: 1.00
                        , idur - 0.002 ::: 0.01
                        ]

I've implemented the FM bell in the style of a DX7 or DX200 algorithm - i.e I've made the connection pattern of the carriers and modulators into a module. This module can be instantiated with configurations (e.g. modulated input frequency) making it more flexible than the previous FM bell. Unfortunately, it still doesn't very compositional at the moment.
