*** Note: this is an Audio Unit Effect Plugin (AUv3) which requires a compatible host or DAW to work. ***

Kosmonaut is Multitap Delay with a twist. In addition to adding echoes to your audio, it packs a bunch of extra tools to put your music in space:

- Tape looper with with variable sound-on-sound decay level
- 4-Tap Delay (placed in series for complex feedback loops)
- LP/HP filters with LFO
- Autopanner
- Ambiance Generator
- Haas Effect Processor (aka 'wavefront precedence effect')

All features are demonstrated extensively in a ton of factory presets, and you can easily add your own user presets, which will automatically carry over across different host apps.

All variables are exposed as AU Parameters in hosts which support automation.

It also has a smart Random-feature, which may come up with usable results :-)

Check out ruismaker.com for the user manual and audio demos.

What’s New

Version 1.0.3

- Fixed problem with huge buffer sizes (1024+)
- Now supports global cross-host AUv3 presets

Ruismaker apps are absolute best

Just wanted to say thanks, and that on a 3rd gen IPad Pro, you are one of, or possibly the only developer that is good enough that all of your apps are FULLY functional, I’ve wasted like 200 bucks on apps that half/don’t work at all on new devices/ios12. You give me hope that I didn’t waste 1400 bucks on an IPad that I mainly got for mobile audio production. Moog pooped the bed, sugarbytes pooped the bed, and so did most others, there are few apps that are fully functional and don’t have audiobus zombie background use and 70% cpu usage. I seriously have to hard reset brand new IPad after attempting to use 30 dollar apps.
Thanks again keep it up, cuz you totally win at this point in the app game. You made higher paid devs look completely incompetent.

I love this effect

I probably am not getting the full range of options from this app (I am using it on iPad Air in GarageBand, primarily as a guitar effect) but what I have gotten has been really cool. First, it never crashes on me. Second, this is the first app I’ve used that I can get controllable feedback from my guitar through the GarageBand app emulators via an effect. So many options, and I have only scratched the surface. Huge fan.

The first traditional AU effect from Bram Bos is an unquestioned must buy.

The AU MIDI apps Bram Bos has put out for iOS are some of the most popular & useful apps available for iOS musicians. This new delay is in that exact same mold, the sound quality is incredible and the amount of control over delay timing and tone is insane. At this price it’s a must buy tool every iOS producer needs in their toolkit. Highly recommended.
