mx44 : Who is interested ?

Post by jujudusud »

Hi everyone,

Is anyone interested in the survival of the mx44 synthesizer?

Does it works on your distros ?

I'm searching how to make it work for now.

Hi.

I have a version running in my OS.
Can't say anything about it's version number.
It runs under ALSA only.

I would like to have it run under JACK. 8)

But I can't find its source code.

Code: Select all

root# mx44
jack_client_new: deprecated
Port subscribed: sender: 129:0 dest: 130:0
engine sample rate: 44100
client activated 

Capture ports:
system:capture_1
system:capture_2
system:midi_capture_1
system:midi_capture_2
system:midi_capture_3
Mx44:Mx44_L
Mx44:Mx44_R

Playback ports:
system:playback_1
system:playback_2
system:midi_playback_1
system:midi_playback_2
system:midi_playback_3
system:midi_playback_5

sizeof 48 voices: 30336, 16 keyboards: 74200, 128 patches: 61440

Voice data loaded

SuspendRefNum error
JackClient::Execute error name = Mx44
/dev/midi: No such file or directory

Voice data saved

Thankyou for using Mx4!

The source code is here: https://github.com/ycollet/Mx44

I got it to compile. I had to install libgtk2.0-dev:

Code: Select all

~/$ sudo apt install libgtk2.0-dev
...
~/$ cd Mx44/src/
~/Mx44/src$ make
~/Mx44/src$ sudo make install
After that I was able to run it, but I couldn't get any sound out of it because I didn't know how to wire up my midi input to it and capture the audio output.

Personally I'd love to see this synth back up and running. It's included in Ubuntu Studio currently, but it doesn't open and I get the same errors as TAERSH.

Hi everyone,

We started in LinuxMAO.org (french) to have a look at this synth.
It is now hosted on LinuxMAO's Github at : mx44-repository

On Archlinux, with some little modifications, I can connect with ALSA/JACK MIDI and audio, and it makes sounds.

I will have a closer look to the code (with my actual little knowledge) and try to make it available to everyone.

Stay tuned !

The AUR package is up to date, thanks to David Adler !
install the package and after that just type un a terminal :

Code: Select all

mx44 -l /usr/share/Mx44/mx44patch -s ~/.mx44patch
The best I can do for now.
Reading the code now.

@TAERSH : The latest version Mx44.2, version 2.0 of mx44 works with jack for the sound and Alsa for the midi really well.
Did you try to build from sources ?
You say you didn't know where to search the sources, now it is here : https://github.com/linuxmao-org/Mx44
Could you please have a test ?

@Michael Willis : if you have built the sources, you have to use the following command :

Code: Select all

$ mx44 -l /usr/local/share/Mx44/mx44patch -s ~/.mx44patch
'mx44' starts the soft, '-l' is to tell where to search the original patch file and '-s' is to tell where your modified patch is located.
please let me know if it's ok.

@briandc : Hey brian ! your site linuxsynth is awesome ! :-)
Please take some time to build from sources and I think you will be happy with this synth again !
Just uninstall the package from the repository first.

From the readme:
Building
cd src
make
sudo make install
should do the trick. The default is to install the binary in /usr/local/bin/ and to install the default patch file in /usr/local/share/Mx44.
I don't like to have programs and its data installed into /usr/local.
I prefer to install my own developments only into /usr/local.
How to change this to use install path /usr?

Just change the `PREFIX` like that :

Code: Select all

cd src
make clean (if you already use make command before)
make PREFIX="/usr/"
sudo make PREFIX="/usr/" install
That will use /usr/bin/ and /usr/share/ to install all the mx44 necessary files.

Confirmed.
Now it works under JACK audio and ALSA MIDI.

I had to install the gtk.2.0-dev files too. Then using make I got this:

Code: Select all

Is this a Debian based system? Is the jack2-devel (or similar) installed?

Exactly what you suggested: libjack-jackd2-dev !!
IT WORKS!! (and so nice to have it back in my arsenal!) Thanks nilshi and @jujudusud and anyone else who worked to get it revived again! :)

C'est un grand plaisir pour moi que ce synthétiseur ne disparaisse pas !

Aussi un plaisir d'aider à ce qu'il soit utilisable par tou(te)s.

:D :D :D :D :D :D :D :D :D :D :D :D :D :D :D :D :D :D :D

I'm currently working on porting the code to GTK3.

Stay tunned !
