Synth

main features

• notes mapped to keyboard keys and pitches (E3 to F5)
• visual feedback with color-coded keys and animation
• real-time audio synthesis with polyphonic support (up to 10 simultaneous notes)

waveforms

• sine (Key: 1) - Smooth, classic sound
• sawtooth (Key: 2) - Bright, classic synth sound
• square (Key: 3) - Buzzy, retro 8-bit sound
• triangle (Key: 4) - Smooth, rising and falling sound

interface

• color-coded keys based on frequency (purple to orange gradient)
• animated splash effects when notes are played
• dropdown melody selector
