The above picture shows the internal MIDI connections of my Home Studio. This setup also uses the separate MIDI equipment from my gig-rig. For use in the Home Studio I have to rewire the gig-rig devices.
There are two MIDI input devices in the Home Studio; The Yamaha WX-5 wind controller and the Oberheim MC1000 MIDI master keyboard. The WX-5 is not connected directly to the Emagic AMT8, like the Oberheim MC1000, but through the Kenton MIDIStream Wireless. I can also connect the WX-5 directly to the WX-in connector of the first of the two VL70-m modules since this WX connection also provides power to the WX-5. For that reason it is important to set up the patch program in the AMT8 in such a way that the MIDI OUT data of the first VL70-m is not sent back to its MIDI IN port.
The MIDI OUT of the Alesis S4+ is only connected to the AMT8 to be able to receive MIDI data (soundbanks, SYSEX, settings, etc.) from the S4+ to store in the PC for back-up.
The Emagic AMT8 works as a router to guide MIDI data that it receives to all the devices. So the MIDI IN ports of both VL70-m's, the Alesis S4+ and the Digitech Studio S100 are connected to the MIDI OUT ports of the AMT8. The AMT8 automatically starts in stand-alone mode, in which it uses certain pre-programmed patches that set-up the routing chart. These can be programmed using the Emagic Unitor software. When it is connected to a PC or MAC, using either USB, RS232 or RS422, it will switch to automatic mode when a MIDI software is started. The Digitech Studio S100 is connected through MIDI since it can receive MIDI data that control effects settings. This way you can program these effects settings in a MIDI track.
My Oberheim MC1000 88-key master keyboard is equipped with an expansion board, the Yamaha DB50-XG, an older model XG daughterboard soundcard. So in my Home-Studio set-up I have an extra 16 MIDI channels with XG and GM soundbanks and it makes it possible to use the master keyboard as a stage piano and synthesizer.
The main AUDIO/MIDI soundcard in my PC is the Yamaha SW1000XG, to my opinion one of the best in its class, great sounds and easily controllable through its own XGEdit software. It contains 20MB of wave samples in its ROM and has 6 24bit digital effects processors. The 1267 XG voices and 46 drum kits are a improved set partly taken from the MU100r/MU90, the VL70-m and CS1x. The card is capable of 64 note polyphony and 32 part multi-timbrality in XG mode, is GM compatible and can be expanded with XG Plug-in boards like the PLG 100-VL.
I use Steinberg's Cubase VST 5.1 sound software for home recording, setting up MIDI files and Audio tracks. I use several extra VST instruments like the Halion SoftSampler and the Halion String Edition. I also use Band-In-A-Box to easily get a nice starting point for creating backing tracks. These separate tracks are then transferred into Cubase to make them sound better.
MIDI files created this way are then stored into GSplayer on the Compaq iPAQ to be played back through the gig-rig. I can also create MP3 or WMA files in the Home Studio and play those on the iPAQ as well.
The Roland SI24 Studio Package Pro digital mixer connects to MIDI in the PC as well through its own PCI card. The motorized faders of the mixer make it much easier to mix in MIDI.
