Sequential (Dave Smith) Prophet 5 合成器音源

The Prophet-5 合成器音源

Sequential (Dave Smith) Prophet 5 是一款合成器音源（桌上型音源版本），將經典的類比合成器音色濃縮在您的操作面板之中。

就像 The Prophet-5 的鍵盤版本一樣，The Prophet-5 合成器音源是 Prophet-5s 系列中最棒的選擇，這是因為它內建了三款 Prophet-5 傳統音色，當中透過真正 Curtis 模擬 VCO 以及 Filter（與 Rev3 相同）體現了傳奇合成器的三個版本：Rev 1、Rev2、Rev3。作為 Dave Rossum 設計的新型 2140 low pass filter，如同在最原始的 Rev1 以及 Rev2 的 2040 一樣。Rev 開關可以在兩種 Filter 設計之間進行切換。同時這款 Prophet 調整了 Filter 的波型以及響應讓它更能分別地符合原本的 Rev1/2 以及 Rev3。

透過真實且扎實的原始聲響，以及實用的性能，這款 Prophet-5 合成器音源絕對能夠符合您對於經典類比聲響的渴望。

振盪器（Oscillators）

• Two authentic CEM 3340 voltage-controlled oscillators per voice
• Simultaneously selectable wave shapes. Oscillator A: sawtooth, pulse. Oscillator B: sawtooth, triangle, pulse.
• Pulse width per oscillator
• Hard sync: Oscillator A syncs to Oscillator B
• Low frequency mode (Oscillator B)
• Keyboard tracking on/off (Oscillator B)

混音器（Mixer）

• Oscillator A amount
• Oscillator B amount
• White noise amount

低頻濾波器（Low-pass Filter）

• Four-pole, resonant, low-pass filter per voice
• Switchable between authentic versions of the Prophet-5 Rev1/2 filter and Prophet-5 Rev3 filter
• Rev1/2 filter is a Dave Rossum-designed 2140, the modern counterpart of the original 2040 filter found in the Prophet-5 Rev1 and Rev2
• Rev3 filter is a Doug Curtis-designed CEM 3320
• Filter can be driven into self-oscillation with the Resonance control
• Keyboard tracking: off, half, full

濾波器包絡（Filter Envelope）

• Four-stage (ADSR) envelope generator
• Velocity modulation of envelope amount

放大器包絡（Amplifier Envelope）

• Four-stage (ADSR) envelope generator
• Velocity modulation of envelope amount

低頻振盪器（LFO）

• Three wave shapes: sawtooth, triangle, square. All waveshapes can be engaged simultaneously
• Both Initial Amount and mod wheel control
• Mod destinations: oscillator A frequency, Oscillator B frequency, Oscillator A and B pulse width, filter cutoff

Poly Mod

• Sources: filter envelope and Oscillator B
• Destinations: Oscillator A frequency, Oscillator A pulse width, filter cutoff

Vintage Knob

• Recreates the characteristics of various Prophet-5 models by varying the behavior of oscillators, envelopes, amplifiers, and other parameters. Go from a very stable “4” — as in Prophet-5 Rev4, (the new version) — all the way to “1,” as in Prophet-5 Rev1, the rarest and most temperamental of all Prophet-5s.

Aftertouch

• Channel (mono) aftertouch
• Destinations: filter cutoff frequency, LFO amount

演出控制（Performance）

• Polyphonic glide (portamento)
• Unison (monophonic) mode with configurable voice count, from one to all five voices and key modes
• Preset switch: when off, the front panel is live; what you see is what you hear
