Hi Andrew and all,

I looked at a few different recording ICs for a DIY sampler but the two I've
tried had a big, annoying delay between when the 'sample' is triggered and
when it decides to play. The ones I tried were APR9301-single shot but great
pitch/sample rate bending, and ISD 1416. This one held 8 'samples' but
didn't reset until the sample was finished playing (and no amount of
electronic abuse would do it :) Can't tell what is used in that kit but it
looks different again. Velleman kits usually only have the component overlay
and a schematic (if your lucky) so you'll need a datasheet to see what's
