Introduction
Aerobic is a step sequencer that controls a virtual analogue drum synthesizer. The instru­
ment produces tight, innovative sounds far beyond the range of traditional drum comput­
ers. This, combined with the sequencer’s capacities and the mixer’s flexible routing op­
tions, makes Aerobic a versatile beat production environment that can be used in live per­
formances.
The drum synthesizer contains six similar, independent units (selectable by the tabs at the
top of the panel). Each unit combines an oscillator and a noise section into one signal that
can be equalized before it is sent to the master mixer. The sequencer (in the middle of the
panel) contains two tracks for each sound unit, selectable via the same tabs as the units
themselves. The filled rectangles within the sequencer’s display represent the unit’s trig­
ger signals and their velocity; the unfilled rectangles form a modulation track whose signal
can be used to change nearly every parameter of the sound engine and mixer over time:
Use the [Modulation] switch in the unit’s master section to select the destination of the
modulation. The master mixer provides classical mixing parameters for each unit (solo/
mute, pan, and, of course, level), along with controllers to adjust the complete ensemble’s
reaction on MIDI messages. Each unit can be triggered by a selectable MIDI note; on a
more complex level, note messages can recall complete ensemble snapshots.

Sound Engine
The drum synthesizer is built by two sound generators, an equalizer, and a master section
that also controls modulation routing. While the oscillator part (on the left side) is based
on sine waveforms with frequency modulation capacities, the noise part (on the right side)
contains a white noise generator with a multi-mode filter. The mixed signal is sent through
an EQ and (within the master section) a final saturator unit before it is passed on to the
mixer.
