VocController is a simple User Interface that creates special midi messages to control the Vocaloid VSTi. It comes in the form of a VST Intrument (VSTi). It allows realtime triggering of vocaloid words using a midi keyboard, it also allows melodies from your sequencer to control the Vocaloid VSTi. It includes a stepping sequencer to create lyrics on specific notes, and supports the standard Vocaloid vibratos and attacks.
It was designed to work with Vocaloid 1 products.
