Portable PIC-synth V2:
It is powered by a 9V-battery and the size is 11x5x3 cm
Controls:Five pots (tempo/duration, data, cutoff, resonance and volume) and seven buttons (play, rec, stop, pattern, step forward, step backwards and rest)
Status is indicated by an bi-colour LED (rec, play, stop, external trig mode, end of pattern)
Four jacks are located on the back of the unit (external trig in, external audio in, filter cutoff and output)
Four different sequences of 16 steps are stored in the internal Eeprom of the PIC18F84.
The sounds are PWM-based 8-bit sounds with both tones and different pitched noise.
