Control Drum Machine Track with External Controller

Is it possible to sequence a Drum Machine track externally? I have an OXI One mk2 sequencer and wanted to trigger the drums from it. The drum track has a MIDI in, but no option to select a channel. Am I missing something, or is this just not possible?

The Drum Track reacts to all midi channels. Haven’t noticed the absence of an channel selector before.
Anyway, since it receives midi data I don’t see any issue sequencing it with an external sequencer that sends midi.

Thanks, it works. The external controller was also sending something using C1 which was making a bit of a mess.
