Sdkc Instruments Bootleg #1

MUSICAL FEATURE

Bootleg #1 is a 2ch envelope generator, envelope follower, and slew limiter.Inspired by Serge's DSG, it is constructed entirely of analog circuitry using the LM3900.

The two slope generators of Bootleg #1 are composed of the same circuit, and the signal input to IN is passed through, and when the gate signal is input to Trig, it functions as an AD envelope.The output consists of a unipolar DC output, a bipolar AC output, an inverted BP output, and an End output where the gate is High from the end of the envelope to the end of Rise.

In addition to controlling Rise and Fall with knobs, there are two CV inputs: a CV input via a switch that selects the modulation destination from Rise/Fall/Both, and a Speed ​​input that always affects Rise and Fall. Masu.Also, when the switch is in the Exp position, the envelope output is internally connected to the CV input with attenuverter, so turning the attenuverter allows continuous adjustment of the response curve.

Rise and Fall can operate in the range of up to 20 minutes or more to approximately 5kHz, including CV input, so they can be used with slew limiters, envelope generators, etc.Using envelope follower, cycled VCLFO, and END outputIn addition to functions such as comparator and trigger delay, it also works as a lo-fi low-pass filter and oscillator at audio rates.
