A system for programming a sequencer in non-real time.

When mixing complex audio material it is often useful to divide the tracks into related sections and mix those sections separately before combining the whole. In mixing film soundtracks, the material would often be grouped as a dialogue stem, a music stem, and an effects stem. Each stem might be mono, stereo or multichannel, as appropriate to the situation. In music mixing, stems might be used for the rhythm section, backline instruments, frontline instruments, backing vocals, lead vocals and effects - or any other combination that suited the particular project.

A connection box terminating a multicore cable (see Snake) which is usually placed on a stage for the easy connection of individual microphone cables.

Resonant low frequency sound waves bouncing between opposite surfaces such that each reflected wave aligns perfectly with previous waves to create static areas of maximum and minimum sound pressure within the room. (See also Modes and Modal Frequencies)

A standard file format that allows MIDI files to be transferred between different sequencers and MIDI file players.

A symmetrical rectangular waveform. Square waves contain a series of odd harmonics.

Song Position Pointer (MIDI).

Sound Pressure Level. A measure of the intensity of an acoustic sound wave. Normally specified in terms of Pascals for an absolute value, or relative to the typical sensitivity of human hearing. One Pascal is 94dB SPL, or to relate it to atmospheric pressures, 0.00001 Bar or 0.000145psi!
