兩位傳奇，一台經典樂器 - Sequential (Dave Smith) OB-6

OB-6 是由兩個對複音合成器歷史發展影響深遠的設計者 - Dave Smith 與 Tom Oberheim 共同研發。

最經典的 Oberheim SEM 聲音被完整的保存在其中，再加上 Dave Smith 系列擁有最適合類比合成器使用的效果器與複音序列器，琶音器。這台六發聲數的 OB-6 將經典音色完美進化，為類比合成器帶來新的樣貌。

詳細規格

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
