From the developer:
SimpleSynth is a small and fast synth, perfect for when you want to try out a musical idea quickly.
It's got a complete general MIDI instrument set built in, and it can load Soundfonts and DLS files.
You may want to check out more software for Mac, such as FuzzMeasure, RealStrat or Strum Electric GS-1, which might be similar to SimpleSynth.
