Thanks for the help on this Alexandre. Getting VERY close now! So, I figured I'd script it. Came up with: #!/bin/sh echo "Infile:" $1 echo "Outfile:" $2 exec midish -b <<EOF dnew 0 "20:0" rw # .midishrc not read (-b), so do it here m off # no metronome import "$1" # get file to play inew mykbd {0 0} # register input to record from onew mypiano {0 0} # register output to route events to tnew mytrack # create a track r # play imported and record for i in [tlist] { # iterate over all tracks if ($i != mytrack) { # if the track is not ``mytrack'' ct $i # set currect track tdel # delete the current track } } export "$2" # save buffer as midi file EOF However, it doesn't work :) First is that the metronome doesn't shut off. Next is the error after hitting ctrl-c: bob$ ./smfrw Downloads/bridge.mid my.mid Infile: Downloads/bridge.mid Outfile: my.mid press ^C to stop recording dkdkd^C --interrupt-- recording stopped 11.10: expression expected afeter '(' If I take out the loop it works fine. But, of course, the original data is saved with the input. I'm probably not understanding the difference between rmidish and midish? -- **** Listen to my CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW:   http://www.mellowood.ca
