Mac USB driver 1.95 had been released on March 24 already. It included a further optimization after sleep mode, and came with TM FX 0.999, which has some specific fixes for the Mac side only.
Today Windows USB driver 1.046 now also includes TM FX 0.999 and these news:
- New: number of WDM devices can now be defined in the Settings dialog. A reduction accellerates the change of the sample rate, reduces the time of continued CPU load, brings quicker behavior on plugging and unplugging the unit, and reduces the boot time of Windows with connected interface. The best setting is 0, means no WDM devices at all. Only ASIO and MIDI are active then. A typical setting is 1 to 3 devices (WDM for Media Player etc.), also causing a much quicker behavior than full WDM channel count.
- Significantly improved performance on current computers at double and quad speed - smaller buffer size required for click-free operation with all channels. Affects all USB interfaces except the Babyface.
- TotalMix FX 0.999
- The current firmware update further improves performance and reliability, please update using RME's flash update tool!
- Note: this driver version requires DIGICheck version 5.71 or higher!
The Windows firmware updater further explains:
All USB interfaces: Possible sample offset when changing between single/double/quad speed and resulting performance problems fixed.
UFX only: Internal loopback did not work in some situations in quad speed with channel 16.
