Luckily there is a bridge to cross this great divide. The Zynthian world uses JACK2 whilst all this network stuff is ALSA based.īasically there are two different world and the aconnect trick on the zynthian will ‘see’ the midi ports but it wont be able to join then to anytihng zynthian like cos they are all in the Jack world… Don’t you love technology. So this is great apart from one thing… ALSA & JACK. Which actually connects the qmidinet port 13):0 to 128:0 which is the other useful command aseqdump which displays MIDI date received on a alsa MIDI port as in the picture at the top of this post. Which display alsa MIDI ports for input and output I really useful couple of commands at this point are run in terminals on either machine and display helpful information. This will build 20 Network MIDI ports on the zynthian, which will auto connect themselves to the 4 ports on your desktop machine. Once it’s run make it will generate a runnable file called multimidicast which you run by going into the directory and typing. exe in windows, You might not be using the same processor). Ssh -X the files ( ) expand them and then run the make file to build the code for your Broadcom architecture ( This is why you couldn’t copy the file around like a. You will have to log on via a remote ssh shell. The local QmidiNet instance is in my case set to 4 ports under the options menu in the Icon… ( ok so it’s not completely irrelevant). Once you have got QmidiNet running on your desktop linux machine ( It could probably be a Pi althou I’m using an old 32 bit laptop) you can see the ports in something like MidiEditor… So what are we actually doing here? Well we are opening up a range of IP linked MIDI ports on two different machines that will appear as ALSA MIDI devices to anything that generates and receives MIDI.īut something has to route the MIDI between devices and most applications have some way of doing this … Luckily our friends in the lighting world (which uses MIDI but calls it DMX) have got a stripped down version that just uses a command line, so will run in our rarefied community. ![]() So because of that, it won’t run on a zynthian. It’s the one between the two arrows and the battery. The UDP based protocol was supported on linux by QmidiNet( ) which is what you would use on a desktop machine because it uses the XWindows infrastructure to display a tiny little system icon. There is a generally agreed way to pass MIDI across Ethernet (IP) networks and it grew out of some Windows stuff.( ).
