Many thanks Chris. Also thanks a lot that you've confirmed that the latest Fix in the repository head fixed it. So, I pushed out a new, v2.5 release in the hope that it is more useful. 

Mamba is a Virtual MIDI Keyboard, a 16 Channel Live MIDI Looper and a (multi) MIDI File player for ALSA / Jack Audio Connection Kit
with a fluidsynth interface, supporting Scala Tuning and Keymap files.

Release v2.5:

• Fix issue #52 mamba 2.4 segfaults on Manjaro when it connects to JACK
• Update libxputty to latest revision

Prebuild binary
Mamba.zip

Release:
