My patch utilizes the serial object to communicate with an external device. The patch was developed on OS 10.6.8 and Max 6.0.4 and it works very well there.
On a much faster OS 10.8 Mac Mini it’s garbage. The message/ack cycle has gotten very slow and inconsistent rendering my patch useless. It’s the same Max version, same serial drivers, no 3rd party objects.
Normally I send messages with a 33ms metro, the device responds with an ACK very quickly, and the next message goes out 33ms later without a glitch.
On 10.8, it’s randomly anywhere between 33ms and 150ms, obviously choking hard on something.
I just updated everything, latest keyspan drivers for 10.8, latest Max6.1, and there is no change.
Anybody have a similar experience?
