Zynewave Podium is a MIDI Sequencer and a host for VST programs. It allows you to record and create music with the available plug-ins. However, since there is no practical case for your inquiry, I recommend checking the page and the available demos/tutorials.
Official website: http://zynewave.com/podium
You also have the possibility of downloading a demo for 32 or 64bit operating systems to test it and see the outcome.
