Sound Production and Manipulation [SPM]  >  Sound Shaping  ]

In terms of MIDI controls, it means the alterations of the duration of any group of MIDI data in the time domain. A whole sequence can be accelerated or delayed by means of tempo adjustments on a ’conductor track’ that imposes its law on all data uniformly. But when certain channels must be independently time-adjusted, or when information concerning only one type of data (like pitch-bend, panoramics or MIDI-volume) must be altered, then a device called ’timescale’ can be called to perform this without affecting the information otherwise not selected.
