Keyboard -> midi question

[Michael Willis]

x42 midi plugins are your friend here: http://x42-plugins.com/x42/x42-midifilter

Specifically, the key range filter or the key split will probably do what you want.

The keyboard probably assigns different midi channels to each split.

[rghvdberg]

Erm no.
You'll see only one midi port from the keyboard.
A midi port uses 16 channels.
A typical midi event, for instance a note on message, has info on which channel the note is to be played.

So let's assume the keyboard sends notes on the left part on channel 2 and the right part channel 1.
Make two midi tracks. Set your DAW to receive midi channel 1 on the first track and midi channel 2 on the second.

Ardour, by default, records and plays all channels on a single midi track so you'll have to adjust that in the channel strip.

Depending on the synth plugin you'll need to setup that to receive on the proper midi channel too. Sometimes the plugin ignores channel info altogether and this is unnecessary.

Also, don't confuse midi channels with audio channels.

tl;dr it's fiddly

Is that plugin pack a repository download?

Yes, if you're using any Debian derivative (Ubuntu, etc.) you should be able to install it like so:

Code: Select all

sudo apt install x42-plugins

It's might even be pre-installed on distros like Ubuntu Studio or AVLinux.

With that said, the suggestion you got from rgvdberg will probably work, assuming that your midi controller sends the splits on two different channels. If you ever want to do something more involved, like having three different sections of your piano play three different sounds or something, x42-plugins would give you a way to do that.
