RME showed us their new M-32 Pro a 32 output 192kHz MADI interface with DC Coupled convertors, allowing you to hook up CV and gate savvy equipment across mulitple channels for modular control.
The M-32 Pro hooks up to the UFX+ which gives you up to 188 channels of IO with MADI interfacing as standard, the M-32 Pro will then hook up to that.
These are pro units though and as such are somewhat spendy, but perfect for the setup that requires both high quality audio and DC signals too.
The UFX+ is around €2200 although you can use the lower cost USB3.0 to MADI interface or AVB if you have a Mac with AVB capability. The M-32 Pro will set you back around €3600.
