Geert, thanks for the post and the effort.
Also, it is important for Eigenlabs to show how to best use the 'harps and having a 'gig-rig' is part of that. The decision to put EigenD on a computing platform was a good one and this effort of yours completes a demonstration of a full, stage-ready, instrument.
IMHO, this is the direction to go for robustness needed for certain settings while still being reasonably portable. That said, there are a number of touring performers using laptops (Zoƫ Keating comes to mind as a busy performer who does this).
So, FWIW, this is the (32bit) geekbench of a current macbook pro running on battery.
I run EigenD on this laptop all the time now (having moved it my Mac Pro) and am happy with the performance although the memory is a bit tight.
The point is that, with your work, people can now see that the eigenharp system can match any performance setting from informal to rock(ous) group.
cheers, m
