Hi Guys Just posted on Sourceforge a new version of these plugins. I added:   - a CV to Hz convertor and Hz to CV (seems to be working ok, the VCO is now in tune)   - The VCA module from AMS (called VCA Lin and VCA Exp)   - The ENV module from AMS With those, it should be possible to create very simple modular synths in Ingen. From the few test I have done, things seems to be working fine, but feel free to provide any comments and feedbacks!
