"Mono-timbral" isn't as limiting as it may seem. With multi-part/timbral instruments, it's generally possible to manipulate a single channel of MIDI data into a halfway decent multi-timbral orchestration, in realtime, through careful instrument selection and note-range limiting.
Putting that into perspective, here is one example of how Ultima III can sound during gameplay, given my attempt at baroque instrumentation and tuning, and leveraging two Yamaha FB-01 units:http://www.symphoniae.com/misc/U3_FB01.mp3
For what it's worth, this would have been entirely possible back in 1986, when the ST version of Ultima III was released.
