[Product Description]This analog 4-pole resonant low-pass filter, equipped with an Attack and Decay (AD) envelope generator, is designed for simplicity and flexibility. The heart of the low-pass filter circuit is the AS3320 analog chip, a modern replica of components used in classic analog synths like the Sequential Prophet 5 and LinnDrum. The cutoff covers the full audio spectrum, with resonance starting self-oscillation at around 70%.The envelope generator offers wave-shaping effects reminiscent of West Coast-style synthesizers, starting from a low frequency of 0.05Hz and cycling up to 300Hz. It supports both instrument and line-level signals, with dedicated controls for input (drive) and output levels, allowing easy transitions between clean tones and clipping fuzz. A multi-color LED visually indicates signal levels, with red for clipping, orange for overload onset, and green for nominal levels.Control voltage and MIDI inputs enable remote triggering of the envelope generator, allowing rhythmic synchronization with external systems like MIDI sequencers and digital audio workstations.This unit is ideal for musicians and producers seeking a versatile filter with classic analog character and modern connectivity.[Condition Description]Operational status: Verified for basic operation unless otherwise noted.Cosmetic condition: Minor signs of use such as small scratches or scuffs may be present.Accessories: Includes the main unit, original box, stickers, and cards.Hello!We deliver carefully selected, high-quality musical instruments from Japan to customers all over the world.Please be sure to read our store policy before making a purchase.[Policies]■ Customs Duties (For International Buyers)For shipments to the United States, import duties are included in the item price.For all other countries, item prices and shipping fees do not include import duties, taxes, or other charges.These costs and any related import procedures are the responsibility of the buyer.Please check with your country's customs office to determine any additional costs before bidding or purchasing.Customs clearance fees are typically collected by the shipping company or upon item pickup.
