Thanks. It works perfect.
Another question is:
Is it possible to run .msl seqscript from bash cmd?
Maybe it's easier then
1 odbedit -c 'set "/sequencer/load filename" filename.msl'
2 odbedit -c 'set "/sequencer/load new file" TRUE'
3 odbedit -c 'set "/sequencer/start script" TRUE'

What is the best way to have a button starting sequencer
from  /script (or /alias )?
