Tea kick is a universal analog circuit, based on an
improved version of the twin T resonant drum sound
design. When a trigger signal is sent to the circuit, it
generates a classic dampened sine wave sound.

)
RESONANCE control affects how resonant the circuit
is. However, the resonance also affects the tuning:
the more resonant, the lower the drum sound. Add
resonance to get longer decaying drum sounds. The
resonance range switch can prevent the resonance
from self oscillating. When you switch it up the
resonance control makes the circuit self oscillate
andthen it can be used kind of as a VCO.
)
Tea kick also has a click generator with tone control.
The click tune control also affects the timbre of the
twin T circuit.
)
TRIGGER input triggers the dampened sinewave
generation at lower resonance settings. Connecting
an audio rate signal to this input results in very pleasing
waveforms at the output. The trigger is visualized by
the led.
)
The twin T circuit can also act as a bandpass filter, for
which there is a WTF input. The aim of the tea kick is
not to provide you with a perfect BPF though, so this
feature has more of an experimental character and lets
you access another interesting point of the circuit.
)
TUNE is the main control knob for tuning the pitch,
which can also be affected via the CV Input and
ATTENUATOR.
CV input is for tuning the circuit so the sound can
range from a bass drum through all the toms up to
a woodblock.
)
CV input goes through the attenuator and is mixed
with the voltage from the TUNE knob, to create the
final pitch control voltage.
)
The click output takes the click impulse away from
the OUTPUT, so you could for example mix it in an
external mixer at a different volume, or use it for other
experimental purposes.
)
The Tea kick has a buffered OUTPUT but is also fed
through a comparator which generates a square wave
on the SQUARE OUT.
