I've finally had a few minutes to read your paper, the overall is interesting and the references on early turntablism (of the more experimental axis) are well done.
The section where you analyse the corelation between a software system / composition and its inherent choices ("1. What can be the justification for using technology as a compositional tool? ") is to me really interesting and could be wider. By means of discussing it more openly and showing current trends of uses of turntables/computer tools for composition (either RT or sequenced), in the paper you limit the scope to your instalation so that's why I felt it could span more.
Also about the instalation piece, the buffer ideas are interesting and the results outgha be great, I'm a fan of glutchy-replicant buffer repetitions but also feel that the resonant-section should add a really interesting harmonic effect to it. Please show more on that
I think it does not make much sense to go in technical discussings or implementation options withou actually whatching the "real thing working". About the references, the cited works are nice (at least the ones I know...which would be about 50%). On the gesture section you could have mentioned the work of Bressin/Hansen on KTH that analyses turntablism gestures quite well (at least record movement and xfader position).
Well, these are my 2 cents,
nice paper anyways!
