This is discussed in another recent thread fwiw - but the Track MIDI channels can be set to be the same - then if you offset the Note param for each track the default (non-chromaticized) patterns will come through on a given range of notes, offset in semitones or whatever, but within the range that the AR can transmit chromatically
Right now there is a documented bug whereby the sequencer plays back two octaves higher than the tapping of the pads which can mean that auditioning what you are playing and getting the same back is subject to a bug fix, hopefully asap
Thirdly, the AR will respond to the lowest 12 midi notes (0-11) and can be played from afar that way, but it won’t output those low notes, it only transmits on the Track Channels over the viable range (currently borked upwards by 2 octaves)
It outputs MIDI in a number of ways, multi/single channel, it’s up to you to master how to catch that particular data in Logic - if you want to use chromatic mode on a track then you simply have to use separate channels
The 2-oct offset bug affects external MIDI playback, not the internal voices, but the sequences you send today may be different to those sent after the bug is fixed (but transposing in a DAW is easy)
