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.

Meowstro last posted a patch note 8 months ago (Feb 1, 2026: Polyphonic and monophonic UI (opens in new tab)).
It got about one update every 6 months over the last year and is rarely updated (12/100). 2 of the last 12 months had at least one update day. Not enough of a cadence to call it regular.
Yes, it looks that way. There have been no builds or patch notes in over 180 days, or none on record at all.
Meowstro: 2 updates in the last 12 months, avg every 14 days. The chart shows the last 12 months, including months with zero patch notes. Counts are dated patch and update posts, not branch builds.
