yep, for instance to exchange notes 60 and 61:
dnew 0 nil wo # register 0 as output device
dnew 1 "MyClient:MyPort" ro # register 1 as input devices
fnew myfilt # create a filter
fmap {any 1} {any 0} # map anything on 1 -> 0
fmap {note 1 60} {note 0 61} # map note 60 -> note 61
fmap {note 1 61} {note 0 60} # map note 61 -> note 60
i # start processing
at this stage, midish processes notes from MyClient:MyPort
and sends the result on midish:midish/0, example:
$ aseqdump -l |grep midish
130:0 midish midish/0
applications connecting to "midish:midish/0" will see what you play
on MyClient:MyPort, but with notes 60 and 61 exchanged.
