Thanks Jan!

I just did that but have no clue what these parameters mean or how to change
them. I have already created a /etc/init/ttyACM0.conf but don't know how to
enter any correct values.

Here are (only) the differences of the two outputs:

good midi in unit:	bad midi in unit:

-cstopb			cstopb
-clocal			clocal
ixon				-ixon
ixoff				-ixoff
opost				-opost
isig				-isig
icanon			-icanon
-iexten			iexten
echo				-echo
echoe				-echoe

If you (or anybody else) could give me a hint which of these settings might
cause "13" to come out as "10" problem and how to change those settings I'd
be extremely grateful!

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

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.
