had the same problem to solve this year to switch between different presets
using Pianoteq and setBfree as softsynths. After some testing I stuck with
MidiLayer. Unfortunately it seems to be abandoned and it does not work together
with Jack's MIDI ports so I have to use virmidi to create virtual midi
"hardware" ports to be able to connect Jack's ports to MidiLayer.
I compiled latest MidiLayer version from SourceForge without big problems (using
Mint BTW). You can send Program Change messages to ML and decide freely about
keyboard splits, note transpositions, which of up to 4 midi input streams goes
to which softsynth and which Program Change messages are to be send to the
From the Readme:
MidiLayer is a simple and easy to use application designed to enhance your live
Manage slots and channels, adjust the velocity and the volume, customize the
note range and connect with modulation wheels and other types of controllers,
all with the help of MidiLayer.
For sending the Program Change messages I created a small hardware device with
an Arduino like micro controller, push buttons and LCD display. This way, after
setting up all the programs by bash script I can close the lid of the laptop
during live performance. Any MIDI controller will be able to perform the same
I furthermore use jmess and jack_connect to create all the necessary conections
Feel free to ask further questions if you decide to try that route.
