stygmorgan is interactive musical workstation software, i.e. an organ with automatic accompaniment able to create complex musical sequences. Developed in C++ using FLTK, it uses the ALSA sequencer to send MIDI messages to external sound fonts. It uses General MIDI and is fully configurable to use any kind of sound font. It can import musical style files in various formats.
GLASHCtl is a simple applet for controlling the LASH Audio Session Handler. When you run it, it will appear as a small LASH icon in your "notification area" or "system tray" (if your desktop manager is compatible with freedesktop.org's "System tray" standard). This is typically somewhere in the panel in KDE or GNOME.
