Subject: Re: M4000D vs. Memotron
Martin, the M4000D is not just "a mellotron", it's a wooden MIDI master keyboard with a mellotron action and polyphonic aftertouch.
You can plug a MIDI cable into its MIDI Out socket and use it to play any MIDI-compatible hardware or software device since 1983! With that lovely "marshmallow" keyboard action :) It's incredibly expressive and powerful in the right hands.
Loads of VSTi softsynths these days support PolyAT, but MIDI master keyboards with polyphonic aftertouch capability are exceedingly rare.
(I did own a Kurzweil MIDIboard for a while, which had it, but it's stiff piano action wasn't really that well suited to PolyAT anyways.)
