Erica Synths Pico DRUM2 is a compact yet versatile percussion synthesizer. It features 8 distinct drum synthesis algorithms! Each algorithm has 3 adjustable parameters (the third typically is decay), ALL OF THEM CAN BE MAPPED TO CV.

## Table of Algorithms

🍋 YELLOW - Pulse Drum - Pulse wave oscillator frequency modulated with a decay envelope.

🔴 RED - Fold Drum - Sine wave oscillator parallely mixed together with same oscillator sent through a wavefolder. Param 2 controls the wavefold and pitch decay at the same time.

🍊 ORANGE Complex Pulse Drum - Pulse wave oscillator modulated with a sine wave oscillator. Decay envelope time is fixed.

🍏 GREEN - Complex Sine Drum - Sine wave oscillator modulated with a sine wave oscillator. Decay envelope time is fixed.

💧 AQUA - Space Wave - Sine wave oscillator and white noise source going through a hi pass filter.

🔵 BLUE - Noise Crush - White noise fed through low-pass and hi-pass filters and a bitcrusher.

🔮 PURPLE - Fold Drum - Sine wave oscillator parallely mixed together with same oscillator sent through a wavefolder with some extra noise on the attack transient. Param 2 controls the wavefold amount, decay controls the pitch envelope decay.

🌸 PINK - Slap - Stack of noise sources with resonant filters emulating a clap sound with an extra overdrive on top.


## Drum2

```
o param1  - usually pitch. glitches at full CW
o param2  - controls other param
o decay   - VCA envelope delay. full CW fully open.
. RGB LED - blinks with trigger
 ^ Mode   - enter/exit blink mode by holding 2 sec.
O CV1     - red: cv controls param2. green: decay. blue: cv controls algorithm selection. 
O CV2     - same + tracks 1v/oct on some algorithms
O Trigg   
* Output
```

### Features 

Push the mode button promptly to switch among 8 algorithms.
Push and hold the button for 2 seconds to enter configuration mode. LED will start to blink in configuration mode. You can assign CV1 input to one of the parametrs. To do so, push the button repeatedly - blinking red LED means the CV is assigned to the Param2 knob. Green - to Decay. Blue - To algorithm selection with CV. To exit configuration mode, push and hold a button for 2 seconds. The LED will stop blinking.
