Surge and obx vst sound garbled 2min after using

[Kevin Norris]

Recently download 3 free vst synths. Surge, vital, and ob3. 
Vital is working fine but after loading surge and recording anything the synth sound quality becomes unusable. So I can not go through the patches to hear what they sound like. However once I start recording the sounds return to normal. Once I stop recording the sound returns to bad. Same thing is happening to the ob3. 
At first I thought it might be surge specific but with the ob3 doing the same I’m wondering if there is more to it. 
Any help would be appreciated. 
Btw surge works fine in my Bitwig DAW

Are they 32 bit? 32 bit can be a crapshoot. Free can also be a crapshoot.

Surge is 64 but.
I did come up with a workaround. 
I have 2 bars of nothing at the beginning of my project. I loop that and can go through all the patches no problem (but once I stop the loop surge goes back to making strange robot noise)
Not ideal but it is a great synth with a lot of sounds and it’s free.

That is very strange! Surge working ok here.

Audio interface specs? Audio buffer and sample rate used?  Are you using ASIO?

Waspi exclusive when just using vst

audiobix usb with Asio when recording audio

Various buffer sizes. 16 bit

It works when I use bitwig 8 with same gear/settings.
