I would really love it if someone would take the time to write a tutorial about how to control VSTi’s in Renoise. I’m totally green when it comes to VSTi’s and it’s been about 3 years since I last touched anything that had to do with MIDI.
Would help a lot, so if anyone feels like helping out 
Guess not 
Hi Makke, in 1.2 there is a new device (vstiParameterDevice) which lets you control all parameters of a vst instrument easily. Just drag those sliders exactly like when using the effects, and you can apply envelopes too in the same way. This has a clear advantage over the midiCCDevice when using vsti’s: all the parameters have names. In other words, no need to check the plugin manual for those CC numbers, all parameters are available at your fingertips
There is another thread about the manual, seems like it will be improved soon with the help of a lot of people.
