FR: Audio Input Patching for VSTi's

[sollapse]

It would be pretty useful to allow input routing to VSTi's that accept a default audio input. Currently the docs state that a VST needs more than 2 default inputs to allow audio to be routed to it (side chaining, etc...). The use case would be for samplers (ie..TX16Wx, MPC Beats) with built-in recording features. Although using the sampler plugin as a normal FX will allow for the track's audio input to be used within the plugin, this requires setting up additional MIDI routing to control the sampler as a workaround.
