Keyboard: Play a melody with your computer keyboard (QWERTY row for white keys, number row for black keys).
16/32 Toggle: Switches the grid between 16 and 32 steps.
Sequencer Grid: Click any square to turn a note ON (red) or OFF. The sequence plays from left to right.
Drum Sequencer Grid: The 4 rows below the synth grid control the drums. Click once for ON (dark red), twice for an ACCENT (bright red), and a third time for OFF.
Note Labels: The labels on the left (C5, B4...) show the pitch for each row.
Transpose: The 'C', 'C#', 'D'... buttons will shift the pitch of the *synth* grid up. 'C' is the default.
Clear Grid: Wipes all notes from *both* the synth and drum grids.
Waveform: Changes the basic sound (timbre) of the oscillator.
Noise / Noise LFO: Blends white noise into the sound. The LFO automates the noise level.
Octave: Shifts the pitch of all notes on the grid up or down.
Volume: Controls the final master volume of the synth.
BPM: Controls the speed.
Cutoff / Resonance: Controls the filter. Cutoff makes the sound darker (left) or brighter (right). Resonance adds a "squelchy" peak at the cutoff frequency.
ADSR (Attack, Decay, Sustain, Release): Shapes the volume of each note.
LFOs (Cutoff, Res, ADSR, Noise): Automatically "wiggles" the control above it. 'Slow', 'Medium', or 'Fast' controls the speed of the random movement.
Spread: Makes the sound stereo. 0 is mono (center). Higher values make the sound wider and richer.
Vibrato: Adds a pitch wobble (like a singer's voice) to the synth notes for a richer sound.
