Sure…I did two things. First, I followed ScottyMac’s post and made sure that the BeatBuddy was transmitting MIDI messages as “MIDI Out”. He has that procedure outlined very well at the top of this post.
Next, I went to my Line 6 M5 and entered the “Settings” panel. In the settings, I made sure that the MIDI send/receive was set to “Omni”. Finally, and this was not apparent to me…but in hindsight, is very obvious, I made sure that the Line 6 pedal was in “Tap Tempo” mode. If you turn the knobs relating to milliseconds for some of your delay/reverb/mod effects all the way to the right (or all the way to the left, for some mod effects, I think) you enter Tap Tempo mode. The millisecond value is replaced by a note image (quarter note, half note, whole, etc) so the pedal “knows” what note value to sync to.
When the Line 6 pedal is in Tap Tempo mode, it automatically syncs to the MIDI clock/signal that is being received. When you turn the Tempo knob on the BeatBuddy, you can actually see the red flashing “Tap” light on the Line 6 speed up/slow down depending on the BeatBuddy Tempo value.
Hope that makes sense and helps!
