Dual Analog Drum Generator

BOBA FAT is a dual voice bass – and kick drum generator. The first voice “soft mallet” generates smooth and warm sounding bass and subbass sounds, whereas the second voice “hard mallet” is rather considered to create kick or tom sounds.

The eight potentiometers on the left control the soft mallet generator. PITCH controls the frequency, LEVEL the volume and BOOST adds low frequencies turning it clockwise and
reduces them turning it counterclockwise. MOD RATE and MOD ATT control an internal LFO and its attenuation. The LFO will affect the frequenciy of the soft mallet voice only. Additionally the LFO can by
synced to the incoming gate or trigger.
TRIG SLEW acts as some kind attack control and reduces transients making it very easy to create very smooth subbass drums. DECAY and RELEASE control the duration of the sounds being amplified by
an internal VCA. PRESENCE changes the prominence of the sound.

The three potentiometers on the very right affect the hard mallet generator. PITCH, LEVEL and BOOST have the same function as for the soft mallet part. PITCH will have a greater effect from 12 to 5 o´clock. Changes from 7 to 12 o´clock are rather subtle, but are set on purpose to add fine nuances with LEVEL and BOOST there.

OUT VOL changes the overall loudness of both drums. GATE accepts any gate or trigger signal to activate the generators. A signal at only at GATE will trigger both mallets. If a additional trigger is inserted to GATE S, GATE only triggers soft mallet and GATE S
triggers hard mallet separately. This way you can have individual drum tracks for both mallets creating very interesting rhythms.

A CV single at MOD CV will override the internal LFO and CV control soft mallet pitch. It doesn´t exactly track 1V/oct, but you will be able to play some melodies. A trigger, gate or clock signal at MOD RST lets you reset the internal LFO with an external signal.
Any CV signal at VARI will slightly alternate the volume or generate additional triggers for the hard mallet circuit (depending on the incoming voltage). This gives you endless ways of
creating fine grooves and interesting rhythms.

The circuit was designed to easily go into distortion and you may be careful using LEVEL and BOOST controls. Boba Fat definitely needs some fine adjustments in order to find the sweet spots.

If you feed the GATE input with a trigger at audio rate you can also use BOBA FAT as a weird sound generator or drone machine.
