[fomus-devel] Trouble with instr-groups

[Ross Mohn]

Hi,

I'm trying to make a grouping for a string quartet. I could use the
:orchestra ensemble-type, but I don't want the two violins to be
sub-grouped  I'm using FOMUS v0.2.28 with Common Music v2.11.3 on SBCL
v1.0.14. I've tried creating a new ensemble-type and a new instr-group,
but I keep getting an error, in what I think is check-settings-type.

Here is the error message I keep getting while "Formatting music...":

>  debugger invoked on a SIMPLE-ERROR in thread #<THREAD "initial thread" {A72C801}>:
>    unknown type specifier: +INSTR-GROUP-TREE-TYPE-AUX+

And here is the relevant code:

>  (defparameter fomus-instr-groups
>    (list '(:quartet
>            (:group
>             (:group :violin :viola :cello)))))
>  
>  (defparameter fomus-output
>    '((:lilypond :filename "Q1.ly" :view t :process t)
>      (:midi     :filename "Q1.midi")))
>  
>  (events (list (Q1test 20)) "Q1.fms"
>    :parts *parts*
>    :instr-groups fomus-instr-groups
>    :ensemble-type :quartet
>    :output fomus-output)

Any ideas here?

Thanks! -Ross
