[LAA] Mamba - Virtual Midi keyboard for Jack Audio Connection Kit release 1.4

[tramp]

Hi

Mamba release v1.4 is out

Mamba - Virtual MIDI keyboard and MIDI file player/recorder

Mamba is not only a Virtual MIDI keyboard, it's also a MIDI looper. It allow you to record, for example a bass loop on one channel and then play along on a other channel with a piano or whatever.

You could save your loops to MIDI files if you wish, in any case, Mamba save your last record and load it on the next start on default.

Mamba is also a MIDI visualizer, it shows not only what you play, it shows as well incoming events. It also allow you to load MIDI files, play them in loop and show the output on the keyboard. You could select which channel you would monitor on the keyboard. You could as well monitor all channels at once.

Mamba includes also support by fluidsynth, you could load a soundfont and directly play along.

Mamba will keep it's settings, so once a soundfont is loaded, on the next start you could just play along with the keyboard. You could load a new soundfont at any time. You could as well exit fluidsynth to use Mamba as plain Virtual MIDI keyboard with the synth of your choice.

Mamba is released under the BSD Zero Clause License license

The GUI is build on libxputty - A damn tiny abstraction Layer to create X11 window/widgets with cairo surfaces

https://github.com/brummer10/libxputty

To build Mamba from source, the following dependencies must be meat.

libfluidsynth-dev
libc6-dev
libsmf-dev
libcairo2-dev
libx11-dev
liblo-dev
libsigc++-2.0-dev
libjack-(jackd2)-dev

So, here is the project page:

Maybe I did not find latest: libsmf seems completely dead. Last release was 2013 and there are some forks on github not exactly active. What scares me a bit:
A fancy, useful and progressing project as mamba depends on a dead library? Just a question - have no problem (yet).

Yes, that is true. Scares me as well a bit.
I choose libsmf because it is part of nearly any distribution out there. I know it have a few bugs, and the patches to fix them been out there, but never been included by upstream. https://github.com/stump/libsmf/pull/7
It's a pity.
I would prefer to use midifile https://github.com/craigsapp/midifile
which is modern and active. Unfortunately I run into licensing issues when I include midifile into Mamba.
To use it I need to re-license Mamba to at least BSD-2. It's not unlikely that I'll do that sooner or later.

I've made a little video from the new live looper feature of the git-version:
