Julf, nice bit of lateral thinking but I think the result may be a bit messy. Often it strings together bits of speech which would then have strange pauses in there. Also when it mentions distances there would be all kinds of errors as it pauses before saying something. I'd be much more likely to miss a turning or take a wrong one.

Mark, maybe the signal to the player to hush/mute/pause (?) when there is silence could be 'caught' or even redefined to do nothing. I know virtually nothing on how button presses and events occur in the Empeg so may well be talking out of my ass.
