Adding --output-24bit to the TiMidity options in Solfege fixes sound problems for me

I am currently trying out GNU Solfege for ear and rhythm training. Solfege uses TiMidity for playback. On my machine, the sound output always started with an annoying crackling for each exercise. Some googling brought up this solution. While that link has nothing to do with Solfege, following its advice helped in my case, too. To remove the crackling in Solfege, I did the following:

In Solfege, open the File > Preferences Menu Choose External Programs Under Audio File Players - MIDI it should say /usr/bin/timidity (or something similar) add --output-24bit to the options for that entry (my complete options for timidity are --output-24bit -idqq %s)

Node takes the event model a bit further, it presents an event loop as a runtime construct instead of as a library. In other systems there is always a blocking call to start the event-loop. Typically behavior is defined through callbacks at the beginning of a script and at the end starts a server through a blocking call like EventMachine::run(). In Node there is no such start-the-event-loop call. Node simply enters the event loop after executing the input script. Node exits the event loop when there are no more callbacks to perform. This behavior is like browser JavaScript — the event loop is hidden from the user.HTTP is a first class citizen in Node, designed with streaming and low latency in mind. This makes Node well suited for the foundation of a web library or framework.Just because Node is designed without threads, doesn\'t mean you canno
