# Hi, my friend wants to run common music on his Windows Xp machine and asked me how to install it and I said "There is Grace, it is easier to install" etc.<br># I downloaded Grace 1.0.1 from Sourceforge: <a href="http://sourceforge.net/project/showfiles.php?group_id=9766">http://sourceforge.net/project/showfiles.php?group_id=9766</a><br>
# Run the Grace.exe. Opened a Lisp window. Write (+ 2 5) CTRL+ENTER and console gave "7". But when I wrote (new midi :time 0 :duration 1 :keynum 60) I get this error:<br><br>>>> Error: unbound variable: new<br>
<br># What may be the problem do you think? I think lisp (chicken scheme) works but does not recognize common music commands?<br><br># (keynum->hertz 60) gave 261.625579833984. <br># (loop for i to 10 collect i) gave "unbound variable loop"<br>
<br># Have a nice day!<br>-ugur guney-<br>
