X-Spat Console for MOTU Digital Performer  We created four faders to control the four global parameters of X-Spat - ‘Room’ (Room Side Size), ’Speakers Number’, ’Rosetta 800 Output Master’ and ‘Doppler Tracking’ – and we have placed them in the top part of the console, for an immediate set-up of these parameters as soon as you open it. The twelve parameters can be modified in real time and are available for each of the 8 audio/MIDI channels; they are logically replicated vertically. The real time parameters are really thirteen but, thanks to the perfect correspondence between the MIDI messages sent by the faders in the DP4mixer and the ones that are necessary to control the audio level entering the X-Spat Spatializer, some space can be saved and the mixer fader can be used directly. The available parameters are the same we have described previously when speaking about X-Spat Controller. In addition, Digital Performer 4 will allow us to record a different type of automation for each object and to add various types of effects in real time to one or more channels. Once more, to set up the X-Spat patch bay, we need the X-Spat Controller software, which can also be used to position the audio sources. We will point you again to various items of software for the management of the audio sources’ movement, through the sending of XY positions in the shape of MIDI Control Change messages: amongst others, the already mentioned ControlAid and the open source software Fingamidi (http://fingamidi.sourceforge.net).
