This doesn't address your need directly, but you might want to be aware that IF you have a sampler, accessing mellotron.com can lead you to a sampling CD containing the entire Mellotron & Chamberlin libraries. Its $200, but its the only sane alternative to trying to buy/maintain the real thing unless you're MADE of money! I have a pal who owns a 'tron and it'll make you go bald prematurely! I love that sound too, but reality ain't always pretty....just FYI. Besides, unless there's an actual 'tron sample in the wavetable a la the E-mu Vintage Keys module, you'll be REALLY hard-pressed to get that same aroma going; its just too electro-mechanical to begin with and basically defies accurate synthesis.
