DXi 2 比 DXi 强在哪里？这里有答案。
- Multiple audio output streams from a DXi
- MIDI output from an MFX or DXi, to the host
- Raw MIDI event processing (e.g. for MTC)
- Flexible, high-resolution time-conversion
- Per-channel patch, note, RPN and NRPN names
- Efficient processing of silent audio buffers
- Pitch marker access
