v1.2.3

1. Low latency shared mode buffer size can be configured (and needed update period is derived from buffer size).
2. Added workaround for hosts that do not set control panel dialog's parent window correctly.
3. Fixed problems with non-standard sample rates (e.g. 49716). When shared mode format converter is used actually any sample rates can be used now.
4. Fixed failed initialization on fixed non-48kHz (44100 etc.) devices.
5. Fixed Cubase 5/7 related problems resulting in no audio.
6. Other minor fixes.
