MPE is a relatively new way to use MIDI, and almost no pre-existing MIDI
receiver can use it correctly.
I have looked into what it would take to get Ardour to work well it, and
concluded that I would put if off for a while. I actually Roger in Berlin
last November and greatly enjoyed interacting with the Linnstrument and
talking to him.

Dear list,
I recently bought a LinnStrument from Roger Linn Design:
http://www.rogerlinndesign.com/linnstrument.html
It is a great isomorphic midi-controller, and as such it is immediately
recognized on Linux.
The distinguishing feature of the LinnStrument is that it senses 3 degrees
of freedom on each note: x-direction, y direction and z-direction
(pressure). The x-direction is mapped to pitch-bend, and y-direction to
CC74.
A cool feature is the "slide", where the pitch-bend is used to slide
between all notes in a row.
To allow individual pitch and CC74 values for each note, it sends each
note on a separate midi-channel ("MPE"):

Bitwig has added support for this, and there is 20 presets in version
1.3.11, where this is used (tag: linnstrument). The LinnStrument controller
is not recognized automatically on Linux in version 1.3.11, but it can be
configured manually, and then it works fine. Note that both midi-in and
midi-out has to be configured, if not there is no sound! It should look
like this: https://ibin.co/2msBJVgpKtf9.png
Now I would like to also use it with the free Linux synths.
Here's what I have been able to make work this far.
Synthv1:
PME works reasonably well: I can play polyphonic in MPE mode, but it tends
to miss the "note off"s.
I can get the slide to work, by setting
<param index="36" name="DEF1_PITCHBEND">2</param>
<param index="78" name="DEF2_PITCHBEND">2</param>
is a preset.
Zynaddsubfx:
I can not get MPE to work.
Sending only on one channel, and setting PWheelB.Rng to 2400 cents, I cant
get the sliding to work, but only when playing with one finger.
If I enable MPE on the LinnStrument there is only an occasional sound,
when it happens to send on the channel, that Zyn is listening on.
I'll love to hear if other LinnStrument users have been able to do more
with any of the free synths on Linux.
All the best,
Thomas
