It is very easy to create all kinds of note and control filters in Pd, if you first learn a tiny bit of Pd. The .pd-files /usr/lib/pd/doc/2.control.examples/17.PART3.midi.pd and /usr/lib/pd/doc/5.reference/help-midi.pd show the available midi objects inside Pd which are for example [notein] and [noteout], [ctlin],... To create mappings, the [route], [select], [moses], [pack], [unpack] and of course all math objects like [>] or [<] are useful, as Pd treats midi data as simple lists of numbers. So a simple midi filter, which just accepts all notes on channel 7, then sends the channel-7 notes to channel 1 would look like this in ASCII-patching: [notein 7] | / [pack 0 0 1] | | \ [unpack 0 0 1] | | / [ noteout ] (Unfortunatly noteout doesn't accept a channel argument like notein does.)
