Synth playing drum track

[Chris UK]

Hi all

Apologies in advance if this is in the wrong place.

This is my first post since purchasing Ableton, most issues I've come across I've managed to work out myself but this one is proving more difficult.

I have a Donner B1 bass synth and have got it setup correctly, however whenever I start a sequence on the synth it starts playing the drum track at the same time and I just can't work out why.

I'm new to making music and synths so I imagine it's probably something really simple, any assistance would be appreciated!

Thanks
