Correct some were some were not exclusive to CW products. However, the SI series (bass, drums, piano..) are NOT exclusive to Sonar, then or now under Bandlab. Just did quick test in a handful of DAW's: Mixcraft, Reaper, FL20, Cubase 8, SO3, Traction 7, obviously Sonar. I even tested as plugins in Fishman Triple Play and MIDI Guitar 2. …NO ISSUES.

Testing CW’s Studio Instrument’s (aka SI series) in PG products ON A WIN 10 64 bit PC: Using the 32-bit version of SI (I only tested with SI BASS) in all three cases ( BIAB, RB or PT2017) no issues: the plugin loads,runs , plays, I can closes the PG application normally.

HOWEVER, when using the 64-bit version of SI Bass , with known good version of JBrigde installed and working: all three PG programs will run that VSTi but upon trying to close either the application or the plug-in window it causes s JBridge or the underlining PG application or both to hang and you can see a still running JBridge Aux64 process still in the “ctrl-alt-del” processes list (it should have closed)

YMMV

Note, the SI series came in two flavors 32-bit and 64-bit .dll's, depending on if you installed 32 or 64 bit Sonar or Music Creator. Although, Bandlab only installs the 64 bit version – should not be an issue if you have JBridge, which Musiclover indicates he's got, but there is an issue with that 64- bit DLL in PG apps!

BTW there is a nice easy to use little utility (free) that can tell you if a .dll is 32 it or 64 bit called “PE Deconstructor.” Once installed just click on ANY dll and it reports basic info - I'll let folks here do their own reading on it first
