XFER LFO Tool as MIDI CC modulation source to Korg MS-20 plu

Hi,

I’m trying (unsuccessfully) to route a MIDI CC from XFER’s LFO Tool to a Korg MS-20 VST plugin. I’ve selected CC 17 in the MS-20 modulation panel and set the CC out # on the LFO Tool to 17, but it doesn’t seem to do anything. I’ve set the MIDI out of the LFO Tool to the VST input, so that should be working ok. Is there anything else that needs to be done?
