Sketch Sound 3D is a 3D workstation for drawing music and visualisation, the visualisation and synthesiser are tightly integrated to ensure that they are controlled by the same drawings and exhibit a psychedelic effect. You can use it straight away with it's samples based synth engine that lets you draw soundscapes. You can draw sounds in 3D using a range of mechanisms, whether that be with your touchpad, mouse, ADSR envelope & iPad accelerometers. An additional orbital guitar like module takes you away from only being able to do pad like sounds, you can use it for doing precise notes and detune it into chords, or use it as a step modulator for other FX. Once you've created your initial pattern then you can look at creating a song using up to 16 different patterns and 4 colour coded output channels.

The internal synth is samples based, it gives you a range of methods by which you can trigger samples so that you could cross fade between synchronised drum loops, or retrigger your sample each time you touch the pad; this way you get the control to be able to work with your own samples and you can use Audio Copy & Paste or iTunes to import your own files (< 2Mb 44100Hz wav preferred, but not mandatory for anything other than audio copy).

When your song is complete then as of version 1.3.1 you can use the 4XZ view to go back and modulate the FX levels on your 4 channels at once for a full blown sound shaping and visualization experience.

Sketch Sound 3D is the baby brother to Sketch Synth 3D, it includes all the features for drawing sounds and working with samples; but does not include communications features like Midi and OSC; and thus does not allow you to connect to external synthesisers and visualisation kit, nor does it let you a Kinect or Wiimote via OSC.

Also Sketch Synth 3D now includes Sketch Synth 2 whereas Sketch Sound does not, so check out the Sketch Synth 3D bundle first.
