pc:make-chord-fixed can't take symbols

[lambdamusic]

Is this by design ?

Eg this fails:

(define *notes* '(c3 g3 b3))

(let ((a (car *notes*)))
        (pc:make-chord a 90 8 '(0 3 5 6 7)))

;Trace: 
;function(round): argument 1 must be: number
;argument values: (c3) #<PROC round>
;Trace: pc:make-chord

It'd work simply by passing (eval a) to pc:make-chord.

Looks like the culprit is round that only takes integers.

Hey @lambdamusic , I think the confusion comes from the fact that the c3 (SPN) symbols are bound to the corresponding midi note numbers, but as above you're still passing the symbol c3 rather than the number.

This will do what you want:

(define *notes* (list c3 g3 b3))

(let ((a (car *notes*)))
  (pc:make-chord a 90 8 '(0 3 5 6 7)))

Note that by using list above *notes* is no longer a list of symbols, but a list of numbers.

Thanks! My bad - I totally missed the fact I was passing a quoted list..
