I have not changed or updated the MacOS in any way, nor any linked hardware, cabling, etc., apart from the external HD. Flash Update panel now shows: 'PCIe revision 20. I have run RME Flash Update Tool 2.9 for Mac OS X Intel 10.7 and up. (For info: the version 4.21 download from the RME website is 'corrupted' according to my Mac, which will not unpack it). I have installed RME PCIe driver for Mac OS X Intel 10.9 and up version 4.13. that has to be on the computer hosting the DAW). I have not knowingly moved any explicitly MIDI-oriented DAW software components, but I have symlinked so many parts now that I may have missed something, OR I may have symlinked something that will not work via a symlink (i.e. I recently replaced this drive, requiring me to re-make many symlinks to get the DAW back to functionality. Projects combine audio with software instruments, mainly EXS24 and Kontakt.Īll audio content for Logic, and many user-modifiable elements such as software instruments, sample libraries, patches and settings are on an external drive.

Monitoring: via TotalMix to Multiface II hardware outputs. MIDI input control: Yamaha XP60 synth/keyboard with MIDI IN and OUT connected to appropriate OUT and IN on the Multiface front panel. Thunderbolt to Sonnet 'Echo ExpressCard/34TB' bearing RME HDSP Cardbus, linked via Firewire cable to Multiface II.Īudio input: RME Octamic via optical cable to Multiface. I-Mac 27-inch, MacOS 10.11.6 'El Capitan', additional monitor via USB 3.0/DisplayLink. I'd be grateful for any help towards putting things right. The Multiface is central to a DAW that I rely on for a major part of my work.

Following a DAW external hard-drive change (details below) the MIDI functionality of my long-serving, trusted RME Multiface II seems to have been lost.
