Subject: for MCP devices that don't handshake, turn them on as soon as we call ::connectivity_... 
X-Git-Tag: 3.0~35
X-Git-Url: https://main.carlh.net/gitweb/?a=commitdiff_plain;h=8f091de64b436fdefa87ae6dae42e5a23889e3c2;p=ardour.git

for MCP devices that don't handshake, turn them on as soon as we call ::connectivity_established() so that _active == true, and we will actually write to them
