I'm using a Solarbotics Freeduino SB, duemilanove compatible, as well as LSDJ 4.7.3. Before using the MIDI monitor, I tried it on the MIDI IN of my Volca Beats unit. It seemed to trigger a pattern start/stop, but nothing else. My Native Instruments Audio Kontrol interface doesn't seem to be the problem. And I've spent all day making sure the GB Link wire was properly wired. The Mode LED's seem to be working normally: flashing when a MIDI signal is sent and set to the last mode of the 7 mode cycle (all lights flash together when selected).

I just assembled a partial arduinoboy lacking MIDI IN ports. I seem to almost have gotten the MIDIOUT mode working but the AB's MIDI OUT port seems to be spitting out garbage. For example I will play a pattern on LSDJ with a just note in the first step with the effect N04 and what I see in my MIDI monitor is a bunch of weird commands.

the AB seems to be sending a lot of different data but I can't seem to get it to produce a simple Note On, or any coherent output.
