macOS Mojave (10.14) Support

Optimized to latest OS then supporting the Dark Mode appearance.


Caution )

Currently we recognize the error on 10.14 that, dragging several rows of Table View caused to no responding but error log about drag image is output.
In PlayBacker series, the table view of 'TrackList' and 'Deck:CueList Mode' are applicable this case. Though this error doesn't seems not causes application crash in PlayBacker, there are some report of crash cases in other apps, so until the improvement of OS or any solution against this error found, we do below countermeasure.

The dragging of multiple rows of table view is disabled on macOS Mojave.

Apologize for inconvenience but please forgive it for safety operation of the apps.

This error not appear on previous OS, and the single row dragging is still available even though on 10.14.

Please regards.

~ Version 2.0.1 Maintenance Update ~


To All Users

PlayBacker for iOS series has been maintenance updated to version 2.0.1 for measures to the problems of 2018/01/13 posted report.
I strongly recommend this update to users of iOS11.x.


This update is including below.

■ A optimization of the file loading system at iOS11.x.

Measures were taken against problems that, 'Audio files existing at Local Storage doesn't appear', 'UserFiles Picker view doesn't appear' or 'Application hang up' when user choose `App Storage` from `Add Tracks` action menu.

■ Fixed a problem that the file move action on UserFiles Picker might caused to application crash.

■ Adjustments of some interface parts appearance.

The level indicator label of deck's volume fader and control switch labels on 4 inch device has been fixed to display with correct size.

■ Adjustments of some operation’s unbalance.

A problem was fixed that, when user add tracks to a deck of 'Repeat All Mode', the first track will be set as the 'Current' and also as the 'Next' too.

A problem was fixed that, in 'Track Editor', user editing for 'Track Title' etc will not be applyed if user tap 'Apply' button while the keyboard is displayed.


I apologize for the inconvenience to users who faced to trouble of file loading in previous version.
As same as this case, please tell me another problems if you have about application behavior, application performance and bugs.

Thank You.
