Make sure the xpand instrument has its instruments switched on. If your xpand instrument is working in another DAW as you said, it is most likely a routing problem in reaper. Make sure the reaper track containing the audio from xpand sends EITHER to the parent folder OR to the Master track. This means 4 MIDI channels in but only two Audio channels out. It only has a pair of stereo outs so multi channel routing cannot be set up. Note that Xpand is multitimbral (plays more than one instrument) but NOT multichannel. In the FX insert window of reaper go to the in/out pin connector (to the right of Param) and make sure the stereo outs of xpand are black inside the boxes (main out 1 and 2) This is often overlooked. Make sure the sound from xpand finds its way back to reaper. On the Reaper Insert FX window make sure the xpand is not “floated” so you can see this window. Make sure the MIDI goes from reaper track into xpand and you see this in the xpand instrument (MIDI activity) There are many ways that you won’t hear anything from Xpand2. Any insight will be appreciated! Thank you in advance. I have looked through every setting and cannot find out why expand!2 is suddenly silent. If the same actual file is responsible for both DAWS, there is no issue with the plug-in itself. He recommended checking Xpand!2 with another DAW. I spoke to an AIR engineer and explained things. First thinking it might be a corrupted plug-in. Another plug-in added to that track works fine. I have removed and added the plug-in and still get no output. It's path to the physical object seems to be there. When I play the synthesizer the track meter indicates a strike/contact. After creating new projects, almost daily for months, and the track connected with Xpand!2 always working fine, suddenly a week ago it produced no output.

Other MIDI tracks call upon other AIR synthesizers that I got bundled with a Keystation 49 MK3.

In the template, one MIDI track calls upon Xpand!2. I have been using Reaper since July 2020 and have set it up where I open all new projects with a template that I created.

There is most likely a simple solution but I cannot find it.
