I have an Allen MDS16 organ with a Vista expansion module attached. I had to modify the Vista power and audio output cables to interface with the stock MDS Expander connections built into the organ.
The organ and the Vista unit play well together. Hauptwerk 4 and the organ play well together (I can use Hauptwerk stops and Allen's native stops together). However, when I launch HW4 on my MacMini PC, access to the Vista sounds is blocked. When I shut down the computer, not just close Hauptwerk, the Vista sounds become available again.
My setup is simple. I run HW4 free version on a MacMini (Late 2009, Core2 DUO with 6GB ram; OSX 10.11.6, El Capitan). The MacMini outputs the HW audio from the headphone jack. I use an adapter to convert the mini phone jack to RCA connectors. The RCA connectors connect to two RCA Y-adapters, L&R. The two inputs into each Y-adapter are Hauptwerk audio and the Vista sound module. The Y-adapters output connects to the Allen MDS16 RCA inputs for the MDS Expander.
QUESTIONS
1. Does HW4 free version have a setting that blocks/unblocks other midi devices? If so, where is this option located in HW4?
2. Could the MacMini be blocking the second sound source?
