I want to use buf-rd to play samples, but it doesnt play the buffer I
expect.
(def babble-samples (load-samples "/home/joakim/roles/music/overtone-sylt/sylt2023/bark_samples/*wav"))
(def hyperrat-sample (load-sample "/home/joakim/roles/Creative/music/hyperrat2/output.wav"))
(definst hyperrat [rate 0.5](play-buf :rate rate :num-channels 1 :bufnum hyperrat-sample :loop false))
;; this plays hyperrat fine, as expected
(hyperrat :rate 0.6)
(definst ab-player-sweep [bufnum 0 offset 0 dur 1 t-trig 1 run 1]
(let [phasor1 (sweep:ar :trig t-trig
:rate (/ run dur);;(buf-rate-scale bufnum)
)
phasor2 (lin-lin phasor1 0 1 0 (buf-frames bufnum))]
(buf-rd :bufnum bufnum
:phase (+ offset phasor2))))
;; this doesnt play hyperrat, it plays babble!
(ab-player-sweep :buf-num hyperrat :dur 80)
What did I miss?

There are some errors in your code.
The arg of ab-player-sweep is called bufnum, but you are setting the :buf-num key, so your synth is using the default buffer, which is the first one you loaded (i.e. buffer 0). You are also passing a synth as an arg, but you should be passing the hyperrat-sample.
In the end buffers for sc are are just ids (integers) that represent a buffer in the server. You could just as well pass a number in there that represents the bufnum. If you log in the console the samples you loaded, you should be able to see their bufnum in there, and you should be able to use that instead of the map, but for convenience you can use them map as well.

Thanks! I expected the error to be something stupid, and it was :)
