Hi,
I'm having a strange problem with the transmission of my Arduino ProMicro MIDI interface on Ubuntu 11.10 (kernel 3.13).
It shows up as ttyacm0 in the system.
Every number "13" that I transmit which could be controller number "13" or a value like program change "13" comes in as number "10".
I suppose it is being recognized as a carriage return (13) which is being executed and then followed by a line feed (10) that actually gets transmitted to the [comport] object for some reason.
Does anybody have an idea how to fix this? Is there a ttyacm.conf (or similar) somewhere in the system that I could edit for a normal (non modem) behavior? Or can I set up the arduino to show up as a different device other than ttyacm?
On my other operating system everything is working fine with the same arduino and programming coming in as ttyacm0 - no special changes. Just another Ubuntu 11.10 with an older (original 2.6) kernel.
Thanks! Ingo
