# MOSAIC *** #### Granular Device > **MOSAIC** lets you reshape audio in real time, with up to 64 grains per track in a 4-second buffer. Sculpt and twist your sound with a mix of precise control and unexpected textures. Build evolving, intricate soundscapes by controlling grain shape and size, embrace per-grain randomness to keep things unpredictable or use the device as a live audio arpeggiator. ***

The MOSAIC device

*** ## Parameters {% tabs %} {% tab title="Page 1" %} **PITCH** \ Controls the pitch of the grains.\ [***Parameter Modes***](#user-content-fn-1)[^1] *** **RATE** \ Controls the rate of grains.\ [***Parameter Modes***](#user-content-fn-2)[^2] *** **SIZE**\ Adjust the size of the individual grains. This parameter is controlled in beats related to the Global Tempo. *** **CONTOUR**\ Shapes the amplitude envelope of grains. At the center position, the envelope forms a smooth sine curve. Negative values skew the envelope into a downward ramp, while positive values shape it into an upward ramp. *** **WARP**\ Controls the amount of fluctuation in the playhead position. Increasing this parameter causes the playhead to move randomly in smooth motions. *** **SPRAY**\ Adds random modulation to the playhead and stereo spread of grain. *** **PATTERN**\ Applies random modulation to the PITCH parameter. PATTERN uses a fixed pseudo-random sequence, that is unique to each instance of MOSAIC. *** **WET**\ Controls the dry/wet of the device. {% endtab %} {% tab title="Page 2" %} **DETUNE**\ Controls the amount of random detuning per grain in stereo. *** **RAND RATE**\ Apply random modulation to grain rate at a per-grain basis. *** **RAND SIZE**\ Apply random modulation to grain size at a per-grain basis. *** **SOS**\ Controls the amount of incoming audio to be recorded into the 4-second buffer. {% endtab %} {% endtabs %} *** ## Actions This device has no actions. *** [^1]: [Read more about Scales here.](https://docs.torsoelectronics.com/appendix/scales) [^2]: * **FREE** * **STRAIGHT** * **TRIPLET** * **DOTTED**
