Sorry – my fault. I had assumed that you were using MIDI from Ableton..
In that case, you can set up the XMT and RCV MIDImaps so that you can load an H9 preset when you load a Space preset. But, if you want (as you do) to pass the MIDIclock, it will also pass the Program Change messages, so you should set the Space and H9 to the same MIDI channel, which should be different from the one your looper uses. Then. I think, you'll be good to go.
