SnapClap

Makes a handclap sound, based on famous Simmons ClapTrap (analog).

This is a successfull attempt to bring famous ClapTrap drum synthesizer (analog version) into eurorack synth world. Considering that is a handclap, there is a lot to tweak – the circuit needs a lot of love, but with proper knob settings you can get really nice claps. Interface consists of 2 main sections – NOISE (also called “crash”) and CLAP (sometimes referred as “ensemble”). Each has its own PITCH and DECAY setting, NOISE has also additional switch for “pulse length mod” (I used simple DPDT, but for more options rotary or switch with center position can be used). There are many triggering options. Device can be triggered from: external pulse (“synth” trigger input), external audio signal (“audio” trigger input with SENSIVITY control), front panel pushbutton (not included in my design), foot switch (I also didn’t need this) and autotrigger (internal generator with SPEED control). The Humanizer circuit doesn’t have any control, but you can use break points to add modulation level pot.
