[Solved] Q) can RE's do IPC? (A, No)

[Billy]

Does the sdk allow for rack extension to do ipc like some vst's use?

No, the sandbox does not have any support for this - there are no pipes, sockets, shared memory, nothing like that. The best you can do is encode some kind of protocol over CV or audio connections to other Rack Extensions, but prior discussions have highlighted that this is risky and may not pass ReasonStudios quality checks.

One example is PolyNote/PolyGate by Blamsoft, which uses encoding to transmit polyphonic note information over CV. Both the sender and the receiver RE need to implement the protocol.
