Right controls lock in, and a block turns green when all of it is right. Keep guessing until the whole board is green. New to synths? Start with Learn.
The Library has every patch so far, Easy to Extreme, with new ones added now and then. Play them in any order.
Hands-on steps from one oscillator to a full patch. Each step sets up a board for you, so there's only one or two blocks to add or settings to change. Play with them, then match the target. Hints are there if you want them.
How fast the wave repeats is its pitch. Twice as fast is the same note an octave higher.
The notes come from the phrase, so you never pick them. Octave moves the whole thing up or down without changing the tune.
Your turn. The target plays the same tune in a different octave.
Each patch is a synth sound, the Target. Rebuild it by ear: change the controls on the board until your Output sounds the same, and every guess marks each control green, yellow or red. Press play on a patch to hear it, or open one to start. New to synths? Start with Learn.
Made a sound you like? Build it in the Sandbox and submit it. If it's approved, it goes in the library with your name on it.
The first patches are on the way. Check back soon.
