Vortex Sound Research

Total beginner here, so thanks for your patience! I have an Arturia Keystep that I control a Volca Keys with via a DIN MIDI cable. That works, but I also need to send MIDI to a Pigtronix Infinity Looper that has only has a DIN MIDI in and there are no MIDI outs on the Volca. Wondering how i can send MIDI clock to the looper and also control the Volca, since there is only one DIN MIDI output on the Keystep. I ended up using the USB out on the Keystep through a USB MIDI host that can talk to the looper. Wondering if this is a legit solution or if i should look into a MIDI hub or splitter? Not sure if the Keystep can control the Volca and also sync the looper at the same time through the DIN output. Thanks!
