THE AI003 LOOPING ADSR ENVELOPE GENERATOR DIY KIT IS A LOOPING ADSR ENVELOPE GENERATOR. IT CAN BE MANUALLY TRIGGERED VIA MOMENTARY PUSH BUTTON, GATED VIA THE GATE SIGNAL, TRIGGERED OR RE-TRIGGERED BY A TRIGGER INPUT, OR SET INTO A LOOP MODE VIA A TOGGLE SWITCH. AN LED SHOWS THE STATUS OF THE OUTPUT.
THIS LOOPING ADSR ENVELOPE GENERATOR DIY KIT CIRCUIT WAS DERIVED (WITH PERMISSION) FROM THE GREAT AND SIMPLE CIRCUIT (ONLY 2 ICS!) FROM
NICOLAS
ON THE
ELECTROMUSIC.COM
FORUMS. WITH SOME HELP FROM THE GREAT
DAVE BROWN
, THE CIRCUIT WAS UPDATED TO PROVIDE ADDITIONAL VOLTAGE PROTECTION, MORE UNIFORM LOOPING AND GATE BEHAVIOR, MORE PRECISE LED MONITORING, AND SOME NICE USER EXPERIENCE UPDATES.
IN GATE OR TRIGGER MODE, THE ENVELOPE CAN BE USED AS A TRADITIONAL ADSR ENVELOPE GENERATOR. IN LOOP MODE, THE OUTPUT SENDS A VARIABLE EXPONENTIAL WAVESHAPE BETWEEN RAMP, TRIANGLE, AND SAWTOOTH LFO WITH CONTROL OVER THE ATTACK AND DECAY OF THE LFO SHAPE.
