C-Beat is a small desk accessory, designed to work alongside your sequencer software, that is incredibly handy. When adding an effect to a piece of music, you often need to know the length of a musical note (crotchet, semiquaver etc.) so you can match your FX unit's delay to the tempo. This is what C-Beat calculates. The Groove Analogue Sequencer Simulator is a program for the Atari ST range of computers which is designed to replicate the effects of early "analogue" sequencers using modern MIDI equipped sound creation devices. Patterns can be created and sent to a number of different MIDI devices, producing both notes and also such effects as pitch bend, patch change, or controller. Patterns can also be transposed in real time utilising either the mouse or MIDI input from a suitable controller keyboard.
