I have the following arrays and I would like to concatenate the contents of each into 1 larger array.

(1 to: 6) collect: [:i | (2**i) inverse ]
(1 to: 6) collect: [:i | (3/(2**i)) ]
(1 to: 6) collect: [:i | (1/3)* (1/(2**(i-1)))]

I tried using the aCollection message which resulted in an"extra characters after the period" error. - not entirely sure why. I have searched the smalltalk quick reference for other options but that message seems like it's on the right track.

You could use commas to concatenate the Arrays, for example

Thanks that works great in my text window! Very elegant, thanks.

However I get an error message "instance of #clip to 1 sent to" my array when i attempt to use this in in the delay scale field of a delay protoype.

If anyone has time to explain why this is the case I would appreciate it.

Here's the final expresion

!DelayScale of: # ({(1 to: 6 collect: [:i | (2**i) inverse ]), (1 to: 6 collect: [:i | (3/(2**i)) ]), (1 to: 6 collect: [:i | (1/3)* (1/(2**(i-1)))]) })

The purpose is to have a sync delay expression that creates the standard note subdivisions in one master array. if you evaluate the expresion in a text file there is one value greater than 1 but i removed that value in the delay sync field, during a test and still received the error.

thanks
