Fixed a bug introduced in last version that messed up the loop recording on some phones that also messed up the UI connections. (Sorry bout that!) Also, as this app was released before Apple's IOS files app was introduced, it used an old system of iTunes file sharing. That has now been removed and instead your loops can be all saved in 2XB303 iOS Files folder, also incrementally the Export section . You can keep them stored in there for later if you have a nice sounding loop you want to keep. You can access them in iOS Files to copy , paste , rename etc. Also fixed some other bugs
MoreThis app is designed for creating electro melodies, dirty phat & funky pure acid techno 303 style basslines, and other electronic music patterns. It's suitable for genres like electro, house, techno, drum and bass, and general EDM.
The app includes a LIVE CONTROL feature that allows you to trigger and transpose both sequences and a new synth pad layer in real-time. You can also instantly switch to saved sequences while playing, making it great for building live tracks.
You can easily capture and export your audio loops to various destinations including AudioShare, Audio-Copy, Email, or the iTunes Shared Folder. The app also supports Audiobus 3 routing, Ableton Link, and IAA (Inter App Audio) for seamless integration with other music apps.
Yes, the app supports syncing with other applications via Ableton Link for precise timing without dedicated syncing. It also supports MIDI sync with external, virtual, or Audiobus connections, allowing it to act as either a master or slave device.
You can extensively tweak parameters like cut-off, decay, Env-Mod, glide, and accent for that classic acid growl. The synth waves have optional harmonic versions, noise, LFO control, glide speed, and PHAT/BASS settings, along with great effects like overdrive, compression, and echo.
