Buchla Tiptop Audio Eurorack 200 Series User manual

QUAD FUNCTION GENERATOR - MODEL 281t
The 281t Quad Function
Generator comprises
four function generators
organized in two pairs. All
four generators can
operate independently or
can be linked in pairs to
generate more complex
output voltages.
Eurorack 200 series
A switch selects one of three modes:
Transient, Sustained, and Cyclic.
Trigger button enables the manual
triggering of the function generators.
Cycle jack enables the cycling of the corresponding
function generator using a gate signal.

QUAD FUNCTION GENERATOR - MODEL 281t
Upon receiving a pulse, a generator’s output voltage ramps up to 10V at a rate determined by the sum of an applied control
voltage and the setting of the attack time knob. When in Sustained mode, the voltage will stay high as long as the input
pulse is maintained; when not in the Sustained mode, or when the input pulse terminates, the output ramps down to 0V at
a rate determined by the sum of the decay cv in and the setting of the decay knob.
At the end of the Decay segment, a transient pulse appears at the pulse output. If the 281t is in Cyclic mode, the cycle now
repeats.
Eurorack 200 series
The time range for both Attack and Decay
is from .001 to 10 seconds.
In the Quadrature mode, generators Aand B(or Cand D) operate in tandem
with their functions shifted by ninety degrees in relation to each other.
