quick question but extremely important ( well to me at least )

ive tried many ways but still cant get them all working together ...so questions
1) will i need to disconnect the sequencer from the eurorack cause since i want the lush bass sounds from the pro 1 i thought it may cause a issue
2) im using 5 din midi or would patching it be a better way
3) and finally what order ,, im currently using swing> rd-6>pro 1 > eurorack ...
thanks guys

It could be a behringer clock issue from swing.
you might swap it with a keystep or check it with a other midi sequencer.

check ppqn preferences on all devices (sometimes hidden in sub-menus or button combinations)
