What's New in 055U4RY

1.31

August 4, 2026

⏺ Transmission 1.31 — misbehaving headstones. In IPad landscape mode the FX part got haunted out of this world, now we chained them back to the graves. The cursed bats are also have better manners now. ⏺ Transmission 1.30 — the crypt opens for everything else. 055U4RY is now two plug-ins: the AUv3 synth, and a new AUv3 FX. Put a drum loop, a guitar or a whole mix through the same fifteen rites and the same panel you already know. Buying today or updating from 1.20, everyone gets both. One app, one price.

まずは時代は変わったんだなと。こうゆう自由な発想のbytebeatアプリが出てきた事に驚きです。音は正統派でインダストリアル&ロックな雰囲気。AU対応、midiにも対応は凄いです。現時点で殿堂入りですが、ユーザーがコードを作って読み込めれば伝説的bytebeatアプリになると思います。

It’s dark and noisy af 🔥 🐀🐀🐀🐀🐀

Response from developer

Anything musical that escapes is a bug I haven't located yet. Thank for the rats!

It rules!

Such a fun synth to play! If the presets are too noisy for you, mess with the settings. I like making it sound just musical enough.
I love the skull guy so much! I try to leave silence long enough for him to close his mouth (I like making the skull look like he’s talking, don’t judge me!).

Response from developer

Nobody here is judging. Skull guy does, obviously. But he's in no position to bring it up.

Very unique synthesis

It has some lo fi grunge and doom, but there is more nuances here than most noise makers. Some of the glitches are real sweet and the experimental aspect shines. Seems like there are quick fixes and a responsive dev so cheers to that. This is for the wilder synth type world where you have to fit your self into its features , and not so much looking for normal synth things. Hails dark wizard

Response from developer

Normal synth things were considered and rejected early in development. Glad the nuance came through under the doom — fixes will keep arriving at unreasonable hours. Hails.
