Windows comes with a MIDI synthesizer, the Microsoft GS Wavetable Synth. This synthesizer allows the playback of MIDI files and will play any MIDI events streamed to it in real-time (albeit with horrible lag, which will be addressed later).
Ammonia is a colorless highly irritating gas with a sharp suffocating odor. It dissolves easily in water to form ammonium hydroxide solution which can cause irritation and burns. Ammonia gas is easily compressed and forms a clear, colorless liquid under pressure.
Free ammonia is a chemical compound of nitrogen and hydrogen with the formula NH3. Technically ammonia in water is called Ammonium hydroxide. In the aquarium hobby the term ammonia also refers to an ionized form called ammonium (NH4+). These are held in equilibrium in the water [Citation needed]. 'Total ammonia' (TA) or 'Total ammonia nitrogen' (TAN) refers to the total concentration of both NH3 and NH4+ in the aquarium water.
