There’s a thread on the Befaco Oneiroi here: Will the Befaco Oneiroi be coming to the 4ms Meta? There are apparently some technical challenges that would need to be overcome to port the Oneiroi to the MM. In addition it is a premium (paid) module in VCV and there is no mechanism currently (and perhaps not ever) to verify that a person has paid for the VCV version before it can be installed and used on the MM.
Regarding the E370 Quad Morphing VCO: Paul Schreiber (the module developer and owner of the Synthesis Technology hardware company,) licensed the rights for the development and sale of plug-in versions of his hardware to VCV. It appears that those rights continued on after Paul’s death as VCV has recently released the E370 and E352. Similar to the issue with the Oneiroi, the E370 is a paid plug-in. Additionally, VCV has not demonstrated any interest in porting their premium plug-ins to the MM, as their primary business interest is marketing paid products for their platform.
