3. Controls
1 Rate
This is used to adjust the pulse rate of the random
clocks generated. At low pulse rates, individual pulses
can be heard (see Fig.1, top), but with higher pulse
rates (see Fig.1, bottom) the sound merges into
noise
.

4. In / Outputs
! DNG / RND CLK
Output !
!!
! produces random clock pulses or digital
noise, depending on the pulse rate set.
" EXT. CLK
Input " is a normalled socket, so that the rate knob
controls pulse rate, unless a signal is patched into this
socket.
This external clock can be provided eg., by a square
wave from a VCO or LFO, or from a MIDI clock, etc.. In
this case, control
1
has no effect. Pulse rate is then
simply decided by the frequency of the external clock.
