![]() Veteran composer Lalo Schifrin puts in a cameo appearance as the conductor. The ‘Baltimore’ concert hall, where a bumbling flute player is unfortunate enough to irritate the fastidious Dr Lecter ( Anthony Hopkins), is the 3000-seat Pasadena Civic, 300 East Green Street (location for the Bette Midler concert movie Divine Madness). Voltage control of input drive lets you modulate the saturation of the filter over time.Red Dragon location: the ‘Baltimore’ concert hall: Pasadena Civic Auditorium, East Green Street, Pasadena | Photograph: flickr/Michelle Chiang No need to boost signal level before filtering for those classic overdriven sounds! While 24dB excels at meaty bass sounds, the brighter filter slope of 6dB is sometimes desirable for signals with higher frequency contentįilter morphing is voltage controlled, and results in some interesting effects when modulatedĪ dual colour LED indicates filter morph position and VCA levelīuilt-in filter core overdrive at the input stage allows you to vary your signal's level up to full saturation. Morph between 6dB and 24dB filter slopes, or set it in-between. Signal and CV levels optimised for the contemporary eurorack modular system (+/-5V CV, 10Vpp+ audio) A resonance clipping switch can tame the resonance feedback at extreme settings, resulting in different toneīuilt in VCA (with disable) after filter saves you the use of a dedicated VCA module Resonance is capable of self-oscillation. Rich 4-pole filtering with a control set made just for modular synthesizersĭesigned from the ground up for versatility in the modular system, the Red Dragon features bipolar attenuverters on its many CV inputs What's more, you can morph between the two pole extremes (6dB and 24dB) to change the slope of the filter on the fly, either manually or through voltage control. The Red Dragon achieves a 24dB/oct resonant low-pass response by cascading four of these stages. The resonance's character is especially profound, resulting in bubbly and sometimes screeching sci-fi tones. Changing this particular attribute over time effectively limits the frequencies that can pass through the amplifier, resulting in filtering! Because attributes other than bandwidth are also changing at the same time, this filter stage has instabilities at certain frequencies along the audible spectrum, resulting in colourful distortions and a character all of its own. One of the modified properties is bandwidth of the amplifier. Instead, the internal properties of a programmable amplifier chip are modulated by a special "programming" input found on these devices. Unlike most other filter topologies, this method did not use capacitors to employ an RC time constant in its core filter stages. The curious filter structure of the Red Dragon favours character over precision sure to impart colourful tone in your source material.ĭuring the 1980's, a Russian electronics designer realised that one could build a musical filter using a fairly unconventional method. The Red Dragon is a 24dB/oct 4-pole low-pass filter realised with a unique Soviet-era filter core.
