(Mike... I'm going to put 12c back on if it's alright with you. You don't need any more information from me with this particular test build, do you?)

This has given us exactly the information we needed. Thanks.

However, I'm a little suspicious that there maybe some hardware reason you are getting such long delays. I've left a prototype Mark II unit running for around four hours this evening (and it was running for most of today too) and I had no audible gaps and a maximum value of 55 which is a bit higher than I'd like but liveable with. I'll leave it running overnight if I can face the display away from my trying to sleep eyes! :-)

Could you leave your unit (running beta12c is fine) connected to a serial port and if you get a skip see if anything is output please?
