Not much help to you but my DSK RhodeZ chorus (and reverb and flanger …) on the DSK GUI does work – at least here. Just like the TTS-1

I’m assuming you are using the DSK ROMpler version (i.e., the actual VSTi "DSK RhodeZ.dll" ) and not the SFZ, SF2, Kontakt, Sampletank, or FL Directwave version (I have them all).

Good Luck
Larry
