Connecting a Keystep 37 help

Hello,

I’ve got a Keystep 37 keyboard coming and I’m trying to work out how to connect it to the Hapax. Can I use the USB port on the Hapax to power they keyboard and send MIDI out or should I use the Keysteps external power and use a MIDI on both?

I’ve already using A, B and C on the Hapax, but I think I can use the D cv port?

Thanks

yup usb port should work just fine. no problem. plug and go after configuring the midi in to usb
