Very well documented set up,
Using an arduino (firmata) and PD (pduino) to make a DIY midi controller for ableton Live.

For the life of me, i cannot get ableton to see more than one CC value.

The patch, its the stock example, with an autoscale and cltout attached.

I'm using IAC drivers.

(note the rx,tx analog pins are not selected but under "pd old analog/digital controls" they are, as you can see values are being received)

(and yes, remote in midi prefs in Live is switched on)

I've troubleshot this to the best of my ability.

This is the tute I'm sure you've all seen:

These are several forum posts that i found were helpful but did not resolve the issue:

This is an example of multiple cltout's functioning using IAC:

A i hope i've just missed something obvious.. any help would be greatly appreciated.

50 views! No one has had this problem? I'll take blind guesses at this point!

Anyone else have a arduino based MIDI input solution i haven't found?

If those number boxes are changing, then I think the patch looks fine. I never had problems sending multiple CCs over IAC. Are you sure the problem isn't on the Live end?

I don't have access to live anymore, so I don't know how to help you there. But like I said, patch looks okay to me.

Ok, good to know. I'll reinstall Live and see what happens..

Thanks for your reply!
