This software is supplied as standard with the CDP PC System, new or Upgrade. It can also be purchased on its own without the rest of the CDP Software.

GrainMill takes an existing sound and extracts from it small pieces - i.e., \'grains\', and recombines them, usually many times over, to form a new sound. This process is known as 'granulation'. It is not, strictly speaking, 'granular synthesis', which creates the sound entirely from within the computer. Rather it granularises an existing sound.

In GrainMill, grains can be very short indeed (less than 20 milliseconds), or several seconds in length. They can be spread very thinly, leaving gaps, or very thickly, creating extremely dense textures. The program has time-varying controls for grainsize, density, pitch, spatial placement and amplitude.

GrainMill also has a built-in time-varying contour (automation) editor called BrkEdit.

Tabula Vigilans (i.e., \'Vigilant Table\') is an advanced algorithmic composition language. Primarily, it is a score processor. It can define and replay a huge range of possibilities, from completely conventional melodic and harmonic music to envelope-shaped multi-event textures with random features. It is not designed to create or shape sounds.

It is script-based, meaning that the user writes a text file which is C-like in nature. Many system, musical and mathematical rules can be called within the script, which also supports reading and writing data files, creating procedures whereby sets of modules can be created, MIDI In and MIDI Out, defining MIDI voices and channels, scheduling of events, etc.

Tabula Vigilans can also operate as a real-time MIDI instrument that can play back pre-programmed or instantly generated music under mouse or keyboard control.

The power of the software is illustrated by the Form-Builder/Score-Builder duo, applications developed by its author, Richard Orton, using Tabula Vigilans. Here the user can select which type of instrumental ensemble to write for, then define the music using a number of high level compositional rules, create the composition and output it directly to the notation program Sibelius.
