Spreadsheets Synth vs KeyBridge for DJs

The 303 lives between the sheets. Spreadsheets Synth is an acid bass synthesizer with a built-in step sequencer — a cultural product of the band Spreadsheets, tuned to 313K and pointed straight at the dance floor. THE SQUELCH Sawtooth or square through a resonant filter with cutoff, resonance, decay, and accent — from rubbery basslines to screaming acid leads. Add distortion for grit, then send it into orbit with the phaser and delay. THE SEQUENCER Program patterns step by step, set the line looping, and ride the cutoff live. It's an instrument for performing, not just programming. PLAYS WITH YOUR WHOLE RIG • AUv3 plugin — load it as an instrument in GarageBand, AUM, Cubasis, Loopy Pro, and any AUv3 host • Standalone app with background audio • MIDI in and out, including Bluetooth MIDI NO STRINGS No account, no ads, no tracking, no data collected.

Stop guessing which track to play next. KeyBridge is the key reference tool built for DJs who want their sets to sound more polished - without memorizing music theory. Here's what the smoothest DJ sets have in common: the tracks share compatible keys. When the next track flows musically from the last one, every transition feels right. When it doesn't, something feels off - even if you can't explain why. KeyBridge gives you the rule in one tap. --- HOW IT WORKS --- Pick the key of your current track. KeyBridge instantly shows you three ways to go next: COUNTERCLOCKWISE (-1) - Bring it down. One step down the wheel. RELATIVE - Switch the mood. Same root, flip between major and minor. CLOCKWISE (+1) - Lift the crowd. One step up the wheel. Tap any suggestion to jump there. Chain transitions. Plan your whole set in minutes. --- WHY DJs LOVE IT --- - Works 100% offline - no signal, no lag on stage - Zero learning curve - tap and go, even mid-set - Full 24-key wheel (12 major + 12 minor) - Built for speed - 15-second auto-return keeps you focused - Haptic feedback - feel the response in your palm - Designed to disappear in the booth - dark interface keeps your eyes adjusted and the atmosphere intact - Retro DJ-hardware aesthetic that looks right next to your gear - iPhone and iPad - use it in the booth, the bedroom, or the bus --- WHO IT'S FOR --- Beginners: Finally understand why some transitions work and others don't. Build your first key-matched set with confidence. Intermediate DJs: Stop relying on memory during live sets. Read the crowd, not your notes.
