Six voice analogue synthesizer with Dual Effects. Studio-quality reverbs, delays (standard and BBD), chorus, flangers, and faithful recreations of Tom’s original phase shifter and ring modulator. Modulation; You can X-modulate a bunch of things from the envelope and oscillator 2. Polyphonic Sequencer! 64 steps. 6 voice. All this packed under four octaves of semi-weighted keys with velocity and channel aftertouch. Features OSCILLATORS * Two discrete VCOs per voice * Continuously variable wave shape (sawtooth and variable-width pulse, plus triangle on oscillator 2) per oscillator * Pulse width per oscillator * Hard sync: oscillator 1 syncs to oscillator 2 * Square wave sub-octave generator (oscillator 1) per voice * Low frequency mode (oscillator 2) * Keyboard tracking on/off (oscillator 2) * Oscillator detune amount for increased tuning instability, from subtle to extreme. MIXER * Oscillator 1 amount * Oscillator 1 sub-octave amount * Oscillator 2 amount * White noise amount STATE-VARIABLE FILTER * Two-pole, resonant, filter per voice with low-pass, high-pass, band-pass, and notch functionality inspired by the original Oberheim SEM filter * Bi-polar filter envelope amount * Velocity modulation of envelope amount * Keyboard tracking: off, half, full. FILTER ENVELOPE * Four-stage (ADSR) envelope generator * Velocity modulation of envelope amount. AMPLIFIER ENVELOPE * Four-stage (ADSR) envelope generator * Velocity modulation of envelope amount. LOW FREQUENCY OSCILLATOR * Five wave shapes: sine, sawtooth, reverse sawtooth, square, and random (sample and hold) * Clock sync (internal or external MIDI clock) * Initial amount * Mod destinations: oscillator 1 frequency, oscillator 2 frequency, oscillator 1 and 2 pulse width, filter cutoff, filter mode, amp X-MOD * Sources: filter envelope (bi-polar) and oscillator 2 (bi-polar) * Destinations: oscillator 1 frequency, oscillator 1 shape, oscillator 1 pulse width, filter cutoff, filter mode, normal to bandpass filter. AFTERTOUCH * Source: channel (mono) aftertouch with bi-polar amount * Destinations: oscillator 1 frequency, oscillator 2 frequency, LFO amount, amplifier envelope amount, filter envelope amount, filter mode. CLOCK * Master clock with tap tempo * BPM control and display * MIDI clock sync ARPEGGIATOR * Selectable note value: 16th note, 8th note triplet, 8th note, dotted 8th note, quarter note * One, two, or three octave range * Up, down, up/down, random, and assign modes. SEQUENCER * Polyphonic step sequencer with up to 64 steps and rests. EFFECTS * Stereo analog distortion * Dual, 24-bit, 48 kHz digital effects, including: reverb (room, hall, plate, spring), delay (full bandwidth digital delay and emulated bucket brigade), chorus, flanger, phase shifters, and ring modulator * Delay sync * True bypass maintains fully analog signal path when digital effects are off. PERFORMANCE CONTROLS * Full-sized, semi-weighted, 4-octave keyboard with velocity and aftertouch * Backlit pitch and mod wheels * Spring-loaded pitch wheel with selectable range per program (1 to 12 semitones up and down) * Transpose controls for an 8-octave range * Hold switch latches held notes on * Polyphonic portamento * Unison (monophonic) mode with configurable voice count, from one to all six voices, chord memory, and key modes * Manual switch: when on, the front panel is live; what you see is what you hear. PATCH MEMORY * 500 user and 500 factory programs in 10 banks of 100 programs each * Direct program access, including single-button access to the current set of 10 programs IN/OUT * Left/mono and right audio outputs (2 x 1/4” phone jack) * Headphone output (stereo, 1/4” phone jack) * MIDI in, out, and thru ports * USB for bidirectional MIDI communication * Filter cutoff expression pedal input * Volume expression pedal input * Sustain footswitch input * Sequencer start/stop footswitch input POWER * IEC AC power inlet for internal power supply * Operates worldwide on voltages between 100 and 240 volts at 50 to 60 Hz; 30 watts maximum power consumption. PHYSICAL SPECS * 31.8” L x 12.7” W x 4.6″ H (80.7 cm x 32.3 cm x 11.7 cm) * 20 lbs (9.5 kg).
