- # Script to ad a Midi device to the RC file of midish. Download from:
- # https://pastebin.com/edit/Q1xS8Ep8
- # Variables:
- # $homedir Home directory.
- # $rcfile RC file for midish.
- # $port Port Number of Midi device to be added.
- # $clientname Client Name of Midi device to be added.
- # $maxdevice Highest dnew number.
- # $linenum Line number with $maxdevice.
- # $lineinput Line after which to insert Midi input device.
- # $lineoutput Line after which to insert Midi output device.
- # Arrays:
- # dnewarray[] Array with dnew numbers.
- # Files:
- # tempaseqdump Tempfile with aseqdump output.

- # - make the script 48 cols wide for use on the Pi screen
