ForumsSoftware ← Virta stopping audio playback

Environment: Virta 1.9.1, Reaper v5.984/64, Mac Pro Late 2013, Sierra 10.12.6

Intermittently Virta stops making sound, most often when I switch presets but also sometimes just starting and stopping my daw triggers it. The animations are still showing audio present. If I take the plugin offline then start it again it works again for a while. I made a quick, shaky and not very helpful video of what's happening here:

I wasn't having this problem with 1.8. Is there a place where I can find old versions?


Hi, sorry about the trouble, I'm not sure what's going on here. Are there any particular presets that seems to be giving you a problem? I haven't seen anything like this with Virta recently but I will give it a shot with Reaper and see if I can reproduce.

Meanwhile here's a 1.8.3 installer: . Note you may have to delete your old plugins manually to convince the installer to go "backwards". You can find them in /Library/Audio/Plug-Ins/Components and /Library/Audio/Plug-Ins/VST.

if 1.8.3 changes anything I'm very interested in your results—please let me know.

If you use other DAWs / plugin hosts please let me know if this issue ever came up outside of Reaper.

I'll try and play around with Virta in Cubase and Ableton soon to see if it's only happening in Reaper.

I reinstalled 1.8.3 and will let you know if it fixes it for me.


1.8.3 is working fine for me in Reaper. Thanks

I think I've figured this one out. Stay tuned for an update soon.

I am also experiencing this issue in Ableton Live 10 Suite and Bitwig Studio 3. I'm on windows 10 enterprise N LTSC (10.0.17763 build 17763). 17-9700k.

It doesn't seem to be caused by any specific presets, and sometimes it occurs after opening a saved project without switching anything at all. The only reliable solution I've found is to delete the plugin, reinsert it, and reopen the preset.

Not sure if it's related, but I just remembered to mention that I also have an occasional issue with Aaltoverb loading either in demo mode or "blank" (text, authorization, etc. missing) in saved projects. Sometimes closing and reopening the project a few times fixes it, otherwise it's the same solution as above here, which is a real bummer when there's a bunch of automation to copy to the new instance.

Sorry you're running into this issue. Please stay tuned for an update soon.

If you experience the problem with Aaltoverb again, can you please send me a screenshot? You can email it to
