I updated my old Sonar X1 Studio to Cakewalk by BandLab.
 
When I insert Cakewalk Sound Center and Roland Groove Synth, I can play a few notes and then the app freezes. I'm inserting them as simple instrument tracks, but I've randomly tried other configuration with no luck.
 
SI Bass and Strings and Dimension LE work fine.
 
Thanks!

Hi JoeMatt, 
I can confirm that the Roland Groove Synth crashed in CBB when I tried to play it.
Worked fine in Sonar Platinum tho.. 
 

Got me going as I love the Groove synth for those classic sounds. I just opened my version of Mony Mony and it's working fine. I am still on 2018 07 version of Cakelab. 

I just inserted Sound center and it also works fine,, It's 32 bit, possibly your copy of Groove synth is also 32 bit? Sometimes 32 bit do not work well. 
 

Thanks for the replies, people. Maybe someone who's had the issue and fixed it will chime in.
Pretty sure my Cakewalk Sound Center is 64 bit -- don't know if that makes any difference.
 
Cheers.
