[Impromptu] Error with loading samples in sampler

[Andreas Körner]

Hi @ all,

i'm new to this list...

I'd like to use impromotu's sampler to load the classic GarageBand  
piano...
As i'm new to Scheme (coming from the beautiful python) I did this:

;I want to build an au host for my personal usage on stage
;therefore this funny namespaces

(define klau:instr:gbpiano:sampleslist (list
(cons 024 "/Library/Application Support/GarageBand/Instrument Library/ 
Sampler/Sampler Files/Grand Piano/024_C0KM56_M.wav")
... Sample Files)
))


;create list with loaded samples
(define klau:instr:gbpiano:sampledata
    (map (lambda (e) (
                       cons (car e) (au:load-audio-data (cdr e))))  
klau:instr:gbpiano:sampleslist))

;;returns the node of the audio unit, filled with nice piano samples ;)
(define (klau:instr:gbpiano)

    (let au (au:make-node "aumu" "play" "MOSO"))
    (for-each (lambda (e) (au:play:set-sample-data au (car e) (cdr  
e))) klau:instr:gbpiano:sampledata)
    'au)

Problem is: impromtu closes without raising an error (if i run  
(klau:instr:gbpiano))

Exception Type:  EXC_BAD_ACCESS (SIGBUS)
Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000018
Crashed Thread:  8

is there anything I could change in my code so this will get working?

thank you

andi
