Tip!
Each mode is based on the natural process of song construction, progressing from demo rehearsals,
selection of various groups of musical patterns, to assembling them to build a track.
Track/Preset Selector Switch
: Selects the track, preset pattern-generator personality, or pattern bank.
The role of this switch is dependent on the operating Mode Selector switch settings.
Tempo:
This sets the tempo (BPM) of the sequencer. It is disabled when the Bass Bot is under the
control of an external MIDI clock source (see Lesson 12).
Audio Controls
Tuning:
This adjusts the Bass Bot’s tuning of the VCO.
Cutoff Frequency:
This sets the cutoff frequency of the Bass Bot's low- pass filter.
Resonance:
This sets the feedback level for the filter. A higher setting results in a resonant peak at the
cutoff frequency producing ‘wetter’ or ‘squelchy’ sounds.
Envelope Modulation:
This controls how much the VCF envelope modulates the cutoff frequency.
Decay:
This controls how quickly the VCF envelope falls away after each note.
Accent:
Notes played by the Bass Bot can be normal or accented. The Accent knob controls how much
louder accented notes are played and how much the VCF envelope is increased during accented notes.
Lesson 2
Pattern Storage and Notation
The Bass Bot is a pattern-based instrument, so it’s important to understand how patterns are stored in
memory. There are two separate sections of pattern storage memory:
Preset Pattern Memory
– Contains sets of patterns that have been created while in Preset Mode by the
Bass Bot. Patterns may be regenerated in Preset Mode and cannot otherwise be modified.
User Pattern Memory
– Contains the core set of patterns for the instrument. These patterns can be edited
(Lesson 7), processed with the arpeggiator (Lesson 11), and used to create tracks (Lesson 9). Patterns in
User Pattern Memory are used when working in Pattern Write, Pattern Play, Track Write, and Arpeggiator
modes.
Each of these two types of pattern memory is arranged into groups, sections, and patterns. This memory
system can be thought of as a set of seven filing cabinet drawers (groups), each with four folders
(sections), that have eight files (patterns) in each.
The following notation is used in this manual when referring to Pattern Memory:
“Group #” refers to the seven groups, labeled 1 – 7 on the Track/Preset selector switch.
(X) refers to a section. Each group contains four sections, called sections (A), (AA), (B), and (BB).
{#} refers to a particular pattern or subset of patterns. Each section contains eight patterns,
{1} - {8}. Patterns can have a length of 1 to 64 steps.
Lesson 3 explains how to select and manipulate groups, sections, and patterns.
