Another option is using DC as a gate:
1. Route DC to CV Out in Mod slot 5, Value 0
2. In a sequencer Track route destination to the Mod 5 Amount, Value 127, the rest at 0
That should provide a clock to your sequencer, as well as a reset. (Not sure if the SQ-1 has a reset.) If you want a faster rate you can set the the Seq Track value to 127 on Step 9 as well--or 1/5/9/13 for a faster rhythm or 1/4/7/10 for a waltz, etc.
Caveat: I don't have an SQ-1 but this works on my Malekko sequencers.
