Store description excerpt
Hear the target. Shape your sound. Find the match before the clock runs out. Play 128 circuits free. Circuit Piano is a sound puzzle game built from live simulations of synths and guitar pedals. Every adjustment changes what you hear. No music theory or electronics experience needed. FIND THAT SOUND Hold GOAL to hear your target, then move the controls to match it. Listen for the difference and watch the waveforms draw closer. Turn a harsh buzz into a warm tone, tame a filter, or dial in a gritty fuzz. KEEP YOUR RUN ALIVE Match each sound before time runs out to build your score. The challenge adapts as you play. Chase your best run and compare scores on Game Center. PLAY WHAT YOU TUNE Use the built-in piano keyboard to play a circuit yourself. Make a pattern with the sixteen-step sequencer, or connect a MIDI keyboard for velocity, sustain, and pitch bend. The keyboard, sequencer, MIDI input, and every control are included free. START FREE Explore 128 circuits across every difficulty level and four live scope channels. Adjust sliders, knobs, thumbwheels, and ribbons. Turn the detailed circuit boards over to inspect the copper underneath. Play offline without ads or an account. CHALLENGE A FRIEND Send a circuit and your score in one link. Your friend gets the same starting point and a score to beat. Any shared or entered eight-character code plays free, including its scope channel for that sitting. Send the higher score back to keep the challenge going.
