What is the right way to save 1TRC sdif files?

Hi prof. Karim,

What is the right way to save sdif files “1TRC”? I am trying this way, but I could not understand why I need to use 3 sdiftypes and how to configure the sdiftypes classes.

Are there mistakes?

OpenMusic is running but never stops! (I have no error!)

I am no specialist of sdif, but i think your 1TRC or your mapcar is outputing “” and nil where sdif expects a list.

PLease have a look at tutrial “07-sdif-write-1”



I was not seeing the nil(s)…
