VSTizer DX21 is a complete Virtualizer/Editor/Librarian for the Yamaha DX21 synthesizer. It turns the DX21 into a virtual instrument which can be controlled directly from the sequencer tracks, without using any computer MIDI resource.
Since RTP-MIDI performs naturally MIDI merging between sessions, the same RTP-MIDI hardware interface can be shared between multiple sessions (for example, you can edit the synthesizer parameters from the VSTizer plugin while the synthesizer is being played directly from a MIDI keyboard connected to a RTP-MIDI bridge)
It allows complete parameter editing and full remote control over RTP-MIDI link, and greatly simplify sound edition compared to what was needed on the DX21 LCD display and complex menu structure.
The VSTizer DX21 is available as a free bundle plugin (available for all Kiss-Box Dual RTP-MIDI and Kiss-Box VSTizer customers).
The VSTizer DX21 also allows to import SYSEX files and turn them into VST banks. You can then get access to the huge sound library available for the DX21.
