The message #clipTo01, sent to 11.294126984127 s, an instance of class TimeInSeconds, was not understood.

I'm using the following code:

| sampleselect |

sampleselect := SamplesFile
fromOldFilename: (HostDriverInterface
getFileWithPrompt: 'Select a Sample'
fileTypes: HostDriverInterface sampleFileTypes
ifCancel: [^ self]).
sample start: 0 s
filename: sampleselect filename asString
loopend: sampleselect filename asString sampleFileDuration s

The strange thing is that if I use this code (adapted slightly) within the LoopEnd field of a Sample Sound, it works. What could be wrong?

Also, why do I need to use the Smalltalk 'filename' asString sampleFileDuration s? If I just use asString sampleFileDuration s after the sampleselect variable, the code doesn't work anymore...

The LoopEnd parameter does not expect a value in seconds. This error arises because you are supplying it with the value:

sampleselect filename asString sampleFileDuration s

"Also, why do I need to use the Smalltalk 'filename' asString sampleFileDuration s? If I just use asString sampleFileDuration s after the sampleselect variable, the code doesn't work anymore..."

Since sampleselect is a SamplesFile, you can send it the message

sampleFileDuration

Perhaps you want the LoopEnd to be a fraction of the total file length? In this case, you could use a ratio:
