Thanks for all the input.
We weren't actually planning to to retune the entire catalogue as an exercise. We wanted the die hard fans to say what they thought about the very idea as there are some extremely emotive people out there when it comes to messing with originality. The notion of doing anything to sacred mellotron sounds would horrify some. Suprisingly you have all hailed the idea! Not what we expected at all but actually quite a revelation and a good one at that.
So, as a final comment on all this, which sounds do you own which you feel would benefit from a good old tweaking?
Thanks for the response, it's what this list is all about.
Best,
Martin
