Simultaneous MIDI notes?

I’m using a Max patch that sends out three or four MIDI notes simultaneously. It works fine in REAPER, all of the notes are received and recorded onto the track. But when I try to use it with Renoise, It only records two of the notes in each chord. Is there something within Renoise I can change to deal with this behavior?

Just making sure, chord mode is on?

Christ, it’s been so long since I seriously used Renoise I totally forgot about chord mode.
