Polyphonic and monophonic UI
Polyphonic and monophonic synthesizer controls are now clearer. Clicking the Synth button twice will now update the keyboard UI. Rendering mode now defaults to Pixelated. You can still change this under Menu - System.
You are a cat with a piano and synthesizer made just for you! Meowstro is designed to be a versatile MIDI interface, allowing you to play using MIDI inputs and outputs. Humans can also interact with it using a standard PC keyboard.

A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.
