Analog Comprehensive Random Source with 5 Unique Outputs
The URA is a random voltage source with 5 unique random outputs. 2 of which are derived from independent white noise sources snagged by 2 discrete sample and hold circuits. While the S&Hs are normaled to these noise generators, any signal can be patched into them - even non random sources, if desired. The S&H inputs have level attenuators.
S&H #2 features an adjustable slew on the output.
A temperature compensated 1V/OCT tracking main clock is hardwired to S&H #1 and normaled to an external clock input jack, which is wired to S&H #2. A range button sports two modes - one goes from sub to high speed audio rate, the other goes even slower to low sub audio. 1V/OCT FM input.
The Toggle A/B output will toggle sampling the inputs of S&H 1 and 2. A very slight propagation delay in the sample pulse permits this output to take unique samples from the two noise sources. In effect this is a unique random source derived from two completely unrelated noise sources. A jumper selects the Toggle circuit to either always use the main clock - or - to use an external clock if patched in.
Random Flux is a smooth random voltage derived from noise and jerky oscillations. Works like a 4th sample and hold with lots of slew/integration applied. The sample timing is wired to the External clk input - which is normaled to the main clock. The Flux can be influenced by positive CV - processed via an internal vactrol. The +/- probability is also voltage controllable.
The random pulse output is an additional clock and digital noise source with 7 stages/divisions. The undivided pulse is the most random and the last division is much more regular. In between is well, um - in between those two degrees of randomness. As an audio source, more regularity exhibits more of a discernible tone embedded in the digital pitched noise. The density/pitch of the gates/noise is adjustable and voltage controllable from sub to audio rate.
Last is an independent vactrol integrator. The integrator smooths out pulses into triangle-shaped voltages at the output. Therefore, the random pulses are normaled to the integrator input - but any signal can be patched into it for processing. This vactrol integrator is different from a normal integrator in that the output is a non-linear curve rather than a linear one. Think of loose S-curves along the expected linear output. The integrator speed is adjustable and voltage controllable as well.
Works as a stable 1V/OCT tracking VCO
High clocking speeds allow the S&Hs to be used for bit crushing/decimating audio and CV signals.
Unique FM capabilities and signal interlacing (using toggle)
Many forms of noise production are possible and are complementary to the Quantum Rainbow v1 and v2.
Designed to maximize self patching possibilities.
