Version updates

Open up new worlds of creative music making possibilities with Audiobus, the app that lets you use your music apps together, just like virtual cables.

New version 3.2.6
Old version 3.2.5
Release Notes This build fixes some MIDI output issues with a few audio units, and improves audio latency for recording apps. It also re-introduces Measurement Mode to the Audiobus section in the system settings app (with a YMMV disclaimer!). And now, Audiobus will automatically quit any zombie apps still undead in the background when Audiobus closes or suspends in the background, saving you more battery, CPU cycles and brains. Enjoying Audiobus? App Store reviews really help!

A creative bass music synth sequencer for electro melodies or dirty phat & funky acid techno basslines.

New version 1.6
Old version 1.5
Release Notes 1: Changed the way the dials work: Instead of jumping instantly to where you touch, you can now smoothly turn the dials by moving up and down the screen after the initial touch on the dial you want to adjust. Also, if you double click the dial, it will snap to either of three nearest points (start, mid-point and end) which is handy for resetting to default positions. If you preferred the original touch to point method, you can choose that way in the settings/system. 2: Moved WAVE shape dial to quick access buttons. 3. Fixed an issue where clicking to open the Ableton Link settings view for the first time would interrupt the main audio processing thread.

Xequence is an advanced linear MIDI Sequencer and Keyboard / Controller for iPhone and iPad.

New version 1.9.5
Old version 1.9.4
Release Notes NEW: - Arranger: Significantly enhanced "Split" feature and behavior when shortening parts: If a split goes through existing notes, these can either be split as well, cut off, or kept at their original length. At the same time, parts have a new option (available in the "Magic Wand" menu) that determines whether notes that extend beyond the end of the part should be cut off during playback (the default) or sound through their entire length regardless (this is also reflected in the part preview in the arranger). This option can be set manually for selected parts and is set automatically and intelligently when creating a split. IMPROVEMENTS: - Add support for all new iOS devices and their screen configurations.
