Having produced controllers since the beginning and synthesisers from the early days, the company added USB-based computer audio interfaces and in 2004 produced the X-Station, intended to provide a complete music production environment with the addition of a computer/sequencer, microphone and monitoring. This was followed by MIDI controllers featuring no keyboard at all, but instead offering varying numbers of buttons, pads, control knobs and sliders, all sending MIDI messages. With the introduction of the SL range in 2005, this was complemented by Novation Automap, a software system that automatically detects and maps the controllable parameters of a plug-in or software application and configures the control surface to address them. Automap has continued to be developed to the present day and is available in a number of formats including an iOS app.
