Blue Arp Arpeggiator Midi set up with Reaper

Just put BlueARP and the intended VST instrument on the same track, BlueARP first and synth after that. No need to setup any midi-routing.

This is the solution I came to as well. However, what if one wants to route a single instance of BlueArp (or other such VST's) to several instruments simultaneously? I struggled with routing, but so far can't get it to make any sound. I set up BlueArp on its own instrument track, then my synth on its own instrument track. I tried using the I/O routing, setting the arp to send on ch1 and the synth to receive on ch1 ... but i got no sound ... same with 'all channels' Only the arp set to receive keyboard input, and the arp was record armed and both the arp and the synth were set to monitor (the synth wasn't set to record tho ... when I did that, I just heard the un-arpeggiated synth Ideas?

Thanks very much
