Well Robin!
I find it totally awesmoe (tpyos intended both! notice how I always used them

)! A great piece of music and a great idea!
I have to ask many questions before I do give my feedback, or rather my impression, as I gather, you're not looking for feedback with this 4 year old piece, right?
Questions.
1. How did you work on the electronics and how did you perform them? From a CD?
2. How did you do the score? I can see the different font but the lines? I doubt they were done inside finale, right? Porbably a tablet? Or maybe a pen in a printed paper and a scanner? Most intriguied by that! EDIT: This will teach me to read posts more carefully: finale 2003 and MS paint! Problem solved
I have to say that in some pieces I've played and seen (Mano, for example, the concert for piano of Schnittke has certain places of such graphics notation, and it works, as you know

) have such notation and it simply works, if there are rehearsals and the playes know each other. I certainly see the point of such a notation method (although sometimes it is used as an excuse by classical, mainly, composers to write less, but this is NOT the case here!).
I like electronics and I love your music Robin. It's not something I hear every day, or something that I will put to my kids to listen, but it is certainly something that "communicated" to me...something. And the thing is that after your work I have a strong urge to go work on my own works, which is great!
EDIT 2: Further to the graphic notation to Mano:
There are times that musicians (especially jazz musicians) need nothing else than some waevy lines to start playing. Had he done different thickness in lines, or different angles, or different something else, the result would've been different, but not accurate every time. And that's the idea. You provide the signal for the performers to respond in the end. nothing more. You give them a role above a simple robot performing your work. While it's very difficult to explain in academia (I've tried and failed, thus I binned the piece completely for my PhD), still there are many valid reason and with this kind of mp3, I'm happy it turned out like this!
Props also to Robin (once more) for making a score!
