Free iPad instrument featuring the classic sounds of famous 80s FM Synthesizers.

New version 1.0.5
Old version 1.0.4
Release Notes We know you are all VERY SMART and STABLE GENIUSES! In this update: Minor bugs fixes. Plus, we'd like to reward you: Pitch Wheel and Mod Wheel controls added! (Tip: Try the Mod Wheel on the "EP & String Stack" sound). We are still improving the app and we appreciate all of your nice comments and listen to every suggestion (especially if you leave a 5-star review)! Thanks again! NEW STUFF: + Pitch Wheel + Mod Wheel + Fixed issue with AudioBus 3 "Not Registering Ports" Pitch/Mod Wheel Tip: (1) Tap anywhere in the Mod/Pitch Wheels to go directly to that position. (2) You can also drag the indicator. Two ways to interact and play! WORKING ON: + Background Audio toggle removed. It wasn't really saving power and was causing problems. We realize that FM Player could be more power efficient and we are working on improving it. In the meantime, it might be best to completely close FM Player when you are not using it to save battery. We appreciate your patience with us as we figure this out. <3 Please note that we all are volunteers. AudioKit does not have any sponsors or investors. We are all musician/developers who love making apps. Any help spreading the word about this app would be appreciated. The more people that know about the apps, the more musicians can enjoy them! Thank you!

Release Notes Fixed: Issue with AudioBus/Inter-App Audio quality for certain device configurations. If you experience noise with Wotja in AudioBus, consider changing the sample rate between 48000 and 44100 Hz in the Wotja Settings screen.

Fixed: Now selects correct voice for editing in Voice editor (not always the first one!) Fixed: iPad Voice Parameters layout margins Changed: "WJ18 BP3 Backings" templates now displays as "WJ5 BP3 Backings" If you have any feedback, comments or discover any problems we'd love to hear from you at support@intermorphic.com

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

New version 1.5.1
Old version 1.5
Release Notes IMPROVEMENTS: - Added a separate, optional MIDI "Panic" button in the top toolbar (can be enabled in the Settings screen under "MIDI / Recording"), and removed the automatic panic sent when tapping stop while Xequence was already stopped. - Better handling of unassigned controllers (they still get listed in the mode menu of the pianoroll editor if the part contains data for that slot, along with the slot number). FIXES: - Disable "Save" button after importing a MIDI file (tapping it would overwrite the MIDI file with a Xequence project file). - Fix a few minor glitches in the file browser. - Disable MIDI "Panic" completely if the destination is Roland Sound Canvas (second attempt at fixing random program changes and ghost notes from that app).
