Personally, the appeal of the Mellotron is that each key is an individual recording of an arrangement of real instruments. This gives the sound a complexity and warmth that I think would be difficult to synthesize. It's also worth noting that the arrangement of the instruments changes over the keyboard on some ensemble sounds to keep the it sounding natural as you play in different octaves. For example, from "Chamber Woodwinds" (Taken from the link below) "The lower octave and a half is English horn and alto flute, the remainder being oboe with C flute. The split point between horn/oboe is offset from the split point between Alto/c flute to give a smoother transition." It's not important to me that they are identical to the originals, merely created in somewhat the same way. I reackon the best way would be to recreate the recordings, cleanly, in stereo, with real instruments and let the user grunge them up if they feel the need. Here is a great site with loads about the sounds: http://www.blackcat.demon.co.uk/tron/right.htm I would be happy to have a bash at recording some sounds as I have the facilities to do so, and can probably find enough tame musos to help me out. -- Frank.
