Hi,
I am thinking about a possible design for the second version of the

position sensing drum pad I have been working on, and I have a question

about latency. I am working around the assumption that 10ms latency is

about the worst it can get before people start to notice it in practice,

so I am thinking of building the pad in a way where the normal latency

is about 1ms, but it degrades to between 10-15 ms in the very worst case

(many simultaneous strikes and pressure variations across the pad).

Allowing this level of degradation would make it possible (I think) to

use an arduino rather than a faster processor, which would be nice.
So the question is, where does this 10ms figure come from, and is it a

reasonable working value? I have picked it up somewhere but I'm not

exactly sure where.
Thanks for any replies.
andy
