This seems to be just another PHP Web Client (MPC) for the famous music server project MPD (Music Player Daemon). But it is the continuation of the existing projects phpMp, phpMp+, phpMp2, phpMp3 and thus as stable as them, although new an shiny. Simple and easy to use. Suggestions and help are welcome! Why should I donate or leave any kind of feedback? As most developers know, open source software cannot be measured in amounts of money. Because the time spent to provide the current state of software is uncountable. So any donation or simply feedback is more than welcome and will encourage the team to move on and provide new features. - Thank you!

A binary waveform synthesizer derived from and based upon Timewave Zero theory by Terence McKenna. His theory proposes that the structure of time is a complex wave with a scalar potential, and the King Wen sequence of the I Ching is the 64 hexagram code from which the waveform of time is derived; that the King Wen sequence maps the linear progression of the human states of mind, which ultimately substantiates this waveform. This theory is the basis for the well-known novelty computer program he and others had developed. This program synth was made in supercollider.
