Doepfer - A-149-2: Digital Random Voltages
a-149-2 is an extension module for a-149-1. it makes available 8 digital random voltages (i.e. only low/high states like a gate signal). the outputs are controlled by the "quantized random voltages" section of the assigned a-149-1 and correspond to the 8 digital outputs of the shift register that is used to generate the quantized random voltages (for details please refer to the a-149-1 description). as the alteration of the a-149-2 outputs is clock controlled by the clk in of the "quantized random voltages" section of the a-149-1 the a-149-2 can be used to create random rhythmical sequences.
the a-149-2 requires the a-149-1 and has to be mounted directly to the left or right of the a-149-1 as an internal ribbon cable connection has to be established between a-149-1 and a-149-2.
a very detailed description of the functions of the random voltages and their application can be found in allen strange's excellent book "electronic music - systems, techniques and controls" from page 82 (refer to a-100 further reading).
this module has a maximum current draw of 40ma. it requires 4 te/hp worth of space to fit in a eurorack frame.
