Release Notes * AUv3 instrument parameters can now be automated * When stopping playback, audio is now faded out to prevent glitches. * Moving the time line is now also possible while zooming * Increased the contrast of the bar display when the grid is enabled * The time code area on top now shows tick marks for beats * The MIDI input dialog now has a new section ‘Channel information’ with an option to keep the MIDI channel information or not for MPE purposes * The AU user interface can now be displayed by pressing the AU button in the drum pattern editor and drum pad display * When a Seaboard or Lightpad Block is detected, channel pressure is always recorded, even with the channel pressure preference set to off * No note events were recorded from the Roli Lightblock. Solved. * Solved a crash after pressing Next on an effect while the virtual keyboard was displayed * Solved a problem with failed rendering of some AU’s that cannot handle changes in frame count * Pressing the little keyboard button in the mixer channel when the virtual keyboard is already displayed now closes it * Rendering stems or rendering a single track to an audio file used a 4096 frames buffer size instead of the selected one which could also cause problems with rendering AU’s like Zeeon. Solved. * The DYN note length in the piano roll was using the grid size setting instead of the dynamic grid size. Solved. * Solved a crash when an insert effect was added to a bus whose input was not connected to any track. * Very long tracks could be created after ‘Split MIDI channels’ if the track did not contain MIDI notes. Solved. * AU MIDI selection was not saved in the project. Solved. * The button in the virtual keyboard display on iPhones that opens the AU editor is now renamed to AU from Edit

Release Notes • Added support for Bluetooth Headphones & Speakers • Updated to latest AudioBus SDK • If you still encounter issues when loading Samplist in apps like AUM via InterApp Audio, open Samplist first and then load it up in AUM.

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

New version 1.8.2
Old version 1.8.1
Release Notes IMPROVEMENTS: - Allow multiple simultaneous connections to/from Bluetooth MIDI devices. FIXES: - Prevent Pianoroll Draw Mode from creating notes outside the part. - Fix rare crash when exporting MIDI file with events that occur before the first bar. - Fix wrong display of number of active MIDI inputs in "Sources" panel when Audiobus was connected as a source. Version 1.8: COMPLETE AUDIOBUS 3 SUPPORT: - SIDEBAR: Audiobus sidebar for switching between connected apps, with access to all Xequence transport controls (Play, Stop (the Rewind icon) and Record) from any other Audiobus app. - SYNCHRONIZATION: Full synchronization (Start, Stop, Tempo, Phase). Please note that Ableton Link has to be enabled in Xequence, all participating apps, and Audiobus. - MIDI OUT: 16 Audiobus MIDI Out ports for connecting up to 16 Xequence instruments to 16 separate Audiobus MIDI lanes or apps. Displays connected apps' names inside Xequence. - COMPATIBILITY NOTE: Some apps hosted in Audiobus as a MIDI receiver might not work correctly due to implementation issues in these apps. In these cases, please send the MIDI directly to the app (do not put the target app on Audiobus' MIDI screen. Instead, put it as a source on the Audio screen and select the app itself as the MIDI Destination on Xequence's instruments screen). This problem can only be fixed by the receiver app developers. - MIDI IN: Audiobus MIDI In port for recording the MIDI output of other Audiobus apps. (all input will currently be merged to a single track, i.e. multitrack MIDI recording is not yet supported, but will be in a future update.) - MIDI THRU: Xequence's usual MIDI Thru will also work inside Audiobus, passing whatever is received from the MIDI lane OR from any other source selected in Xequence's settings to the current track's instrument, which can be an Audiobus destination, hardware, OR another app. - STATE SAVING AND RESTORE: Xequence will save the current project, including all modifications done since the last save, in the Audiobus preset, and restore it when a preset is recalled. - MIDI MERGE: Xequence merges all MIDI input both from the Audiobus lane AND any other MIDI sources, both hardware and software, and can record it or send it to the current track's instrument (MIDI Thru). - Please note that Audiobus MIDI and State Saving still are very new and evolving technologies, and you may encounter issues which are caused by problems in third-party apps. However, please do let us know if you have a problem that you suspect might be due to a Xequence bug, and we're happy to investigate! IMPROVEMENTS: - MIDI Input has been cleaned up: The "Any" source has been replaced by "Xequence Destination" and can be enabled alongside the other available sources. To send MIDI to "Xequence Destination", most apps have a menu that will list "Xequence Destination" so you can send to it. Of course, the other way around (Xequence actively connects to other sources) is still available by enabling one of the other sources in the "Select MIDI sources" panel. - Better contrast for instrument colors in "Light" theme. - Pianoroll: When switching between note and velocity editing, scroll and zoom are now preserved. - Various optimizations. FIXES: - Pianoroll: Fix vertical scrolling of keys on the left sometimes not in sync with scroll position of editor. - Pianoroll: Fix slightly wrong vertical zoom in Drum editor mode when using "Zoom All" with the ruler enabled and "Ruler Auto-Dismiss" disabled. - Keyboard: Fix sliders with "Return" option sometimes not returning to their zero position.
