Hy,<br>
<br>
I was studying Patterns topic in CM2 and got errors trying to do Example 3 (Creating patterns programatically).<br>
Part of the error message says:<br>
<br>
LOOP ERROR: 'each' does not support initializations.<br>
clause context: 'EACH K IN (NEXT PAT T)'<br>
<br>
I tried many things (actually I'm a beginner, so it complicates a lot), and it did work when I substituted line:<br>
each k in (next pat #t) as x from 0 by rate<br>
<br>
by these two lines:<br>
for x from 0 by rate<br>
each k in (next pat #t)<br>
the console gave me no error messages, by I think the sound result was not the expected (it should vary each evaluation, but keeps the same).<br>
<br>
How can I correct this?<br>
<br>
Thanks.<br>
