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.
