Pixel Monster Music Sequencer UI

Goal: Create a vertical pixel-art sci-fi music sequencer interface showing four cute monster audio tracks, like a retro game synth dashboard.

Canvas: Tall portrait mobile screen, 720×1200 style, dark navy background with glowing rounded rectangular panels and crisp pixel-art edges. Use a limited neon palette with cyan, mint, red, purple, and yellow accents. Everything should look like high-resolution pixel art, with subtle scanline/dither texture and no photorealism.

Layout: At the very top, create one wide rounded header bar. Inside it place exactly 6 discrete control/readout elements: 1 small alien/robot face icon on the left, 1 dotted equalizer readout beside it, 3 square transport buttons in the center showing stop, play, and record icons, and 1 dotted menu/grid indicator on the right.

Main track area: Stack exactly 4 horizontal rounded track panels, each with a left track number and a vertical level meter, a monster character on the left, a circular dotted status control in the middle, and a large rotary knob on the right.

Track 1: Label number “1”. Mint/teal theme. The creature is a sleepy squat round monster with small horns/spikes, closed eyes, lying down, with “Z Z” sleep marks above it. The middle control is a dotted circular ring with a small center dot. The right knob has a pale yellow arc and one mint indicator dot near the top.

Track 2: Label number “2”. Red theme. The creature is a red one-eyed monster standing aggressively, mouth open with teeth, one arm raised and casting a crackling magical red orb above its hand. The middle control is a red dotted ring with a solid red center dot. The right knob has a red arc and one red indicator dot.

Track 3: Label number “3”. Cyan theme. The creature is a blue dancing one-eyed monster wearing headphones, smiling with a toothy mouth, arms raised, with exactly 2 floating music notes near its head. The middle control is a cyan dotted circle containing a play triangle. The right knob has a cyan arc and one cyan indicator dot.

Track 4: Label number “4”. Purple theme. The creature is a purple energetic monster with multiple ghosted afterimage duplicates behind it, big eyes, waving arms, small sparkle marks around it. The middle control is a purple dotted circle containing a play triangle. The right knob has a purple arc and one purple indicator dot plus a tiny triangular tick at the top.

Bottom mixer section: Create one wide rounded bottom panel. On the left, include exactly 1 square album-art tile with a glowing mint border, showing a floating mossy cube planet or asteroid with small orbiting rocks and tiny stars. To the right of the album art, arrange exactly 5 square effect buttons in one row: 1 purple concentric-circle/radar icon, 1 cyan vertical waveform/spectrum icon, 1 green pixel burst icon, 1 yellow audio waveform icon, and 1 yellow ringed planet icon. Beneath those buttons, add exactly 2 horizontal audio meters: the left meter has a microphone icon followed by green-to-yellow vertical bars, and the right meter has a speaker icon followed by green-to-yellow vertical bars, separated by a thin vertical divider.

Text content: Only include the visible track numbers “1”, “2”, “3”, and “4”; do not add readable labels or words besides the two “Z” sleep marks. Use abstract pixel icons rather than detailed typography.

Style constraints: Retro 16-bit pixel-art UI, dark futuristic synth console, glowing outlines, rounded panels, clean symmetry, high contrast, playful monster characters, no watermark, no realistic 3D rendering. Make the main accent color palette customizable: {argument name="primary neon color" default="mint cyan"}, {argument name="danger track color" default="hot red"}, {argument name="party track color" default="purple"}, {argument name="background color" default="deep navy"}, {argument name="interface theme" default="retro monster music sequencer"}.
