Taurus 3 – Behind-the-Scenes – Critical Listening
Stefan Lessard on the Taurus 3 Bass Pedals
Carolina Chocolate Drops x Taurus 3
Taurus 3 是經典 Taurus 1 類比 bass 合成器的升級版. T3 有兩個震盪器, 24 dB/Oct 低通濾波器 low pass filter, 兩個 Envelop 產生器, 一個低頻震盪器.
前面板可以控制調變 modulation, 震盪器 oscillator, 濾波器 filter, Envelop 產生器和琶音器參數. 還有專門控制升降 8 度, 滑音, 移調及音量的按鍵. 左邊使用者介面提供音色記憶管理功能, 一般功能設定, MIDI 功能控制以及工具程式. T3 有 52 組音色, 4 組不能修改, 48 組使用者音色.
Performance Interface
13-note velocity sensitive bass pedals
1 Volume Footwheel Controller with optical mechanism
1 Programmable Footwheel Controller with optical mechanism
9 Footswitches for selecting Bank and Presets, Transpose, Glide On/Off, Decay On/Off, and Octave Up/Down
Synthesizer Sound Engine
100% Analog Audio signal path based entirely on the highly acclaimed Taurus I synthesizer circuits
2 x VCOs (Voltage Controlled Oscillators) with sawtooth waveform outputs
1 x VCF (Voltage Controlled Filter) with 24dB/Octave Lowpass Filter with the classic Moog Ladder Filter topology. 20Hz-20KHz Frequency Response
1 x VCA (Voltage Controlled Amplifier)
Synthesizer Modifiers
1 ASD (Attack-Sustain-Decay) VCA Envelope
1 AD (Attack-Sustain-Decay) VCF Envelope
1 x LFO (Low Frequency Oscillator) with Triangle, Square, Sawtooth, and Ramp waveforms with adjustable amounts to the VCOs and VCF. The LFO is syncable to MIDI Clock or Tap Tempo
1 x Arpeggiator with Latch Mode for generating recurring musical patterns from Bass Pedal Input. The Arpeggiator is syncable to MIDI Clock or Tap Tempo
Programming Interface
52 Presets total in non-volatile memory consisting of one bank of 4 factory presets, and 12 banks of 4 user-programmable presets
Preset selection can be performed with the Value knob, or the combination of Bank footswitch, Bass Pedal, and Preset footswitch
Factory Presets include the classic Taurus, Bass, and Tuba presets, plus the new Taurus III preset
Two selectable levels of LED illuminated switches access the classic Taurus parameters or the Taurus 3 LFO and Arpeggiator parameters for editing with the Control Footwheel or the Value Knob
15-segment LED bargraph displays the value of the currently selected parameter
Classic Taurus Parameters in the OSCILLATOR section
B.FREQ: Oscillator B Frequency coarse offset to Oscillator A
BEAT: Oscillator B Frequency fine offset to Oscillator A
GLIDE: Glide Rate
OCTAVE: Low, Medium or High
MIX: sets the loudness ratio between Oscillators A and B
ATTACK: sets the Rise time for the VCA Envelope Generator when a note is played
SUSTAIN: sets the maximum level for the VCA Envelope Generator when a note is held
DECAY: sets the fall time for the VCA Envelope Generator when a note is released
Classic Taurus Parameters in the FILTER section
CUTOFF: sets the lowpass filter cutoff frequency
RESONANCE: sets the amount of signal fed from the output to the input of the lowpass filter. Can be set for filter self-oscillation
ATTACK: sets the Rise time for the VCF Envelope Generator when a note is played
DECAY: sets the fall time for the VCF Envelope Generator when a note is released
AMOUNT: sets how much the VCF cutoff frequency is modified by the VCF Envelope Generator signal
Taurus 3 Parameters in the LFO Section
SQUARE: Radio button type switch selects the LFO square waveform
TRIANGLE: Radio button type switch selects the LFO triangle waveform
RAMP: Radio button type switch selects the LFO ramp waveform
SAW: Radio button type switch selects the LFO sawtooth waveform
RATE: sets the LFO Rate
LFO FILTER AMOUNT: sets the amount the LFO modulates the filter cutoff frequency
LFO PITCH AMOUNT: sets the amount the LFO modulates the VCOs frequencies
LFO SYNC: On/Off switch enables starting the LFO waveform cycle with each note played on the Bass Pedals
Taurus 3 Parameters in the ARPEGGIATOR Section
PATTERN: sets the pattern of the arpeggiator
ORDER: sets the order that the pattern of the arpeggiator is output
OCTAVE: sets the number of octaves for the arpeggiator pattern
ON/OFF: turns the arpeggiator on or off
LATCH: turns the arpeggiator latch function on or off
VALUE knob is used for selecting presets or editing parameters
PRESET switch toggles between the current stored preset and its edited form
MASTER switch selects a menu of Advanced Preset functions, Global settings, and System Utilities
CURSOR switch navigates the screen of the LCD User Interface
STORE switch initiates the storing of presets
Field-upgradeable firmware using MIDI SysEx
MIDI Implementation

Taurus Sound engine can be played by MIDI Note messages
Preset parameters controllable by MIDI Control Change (CC) messages
Bass pedals transmit MIDI Note On/Note Off messages with user selectable velocity resolution
Volume Footwheel transmits MIDI CC 7 (Volume) data
Control Footwheel transmits MIDI CC corresponding to selected parameter
Presets and Global Settings can be sent or received through MIDI SysEx
