Those suggestions require heavy hardcore DSP programming.
A simple sampler could be achieved much easier by an A/D-converter, a 
clocked counter and a SRAM chip. Dieter did this in the SSS-modules 20 
years ago.

cute idea, but assumingly not easy to achieve (at least in an exact 
reproducable way).

Very fine idea. This would require to have the same clock, but 
independant address counters. This leads again to a even more modulized 
version: separate modules for
- highspeed VCO module,
- VC addresscounter module,
- A/D-RAM-D/A module

Definitely true
