[sdiy] Random Voltage Generation

[Curtin, Steven D (Steven)]

Matti,

Your point is a good one.  As Dana Massie (who worked as one of the main DSP
people at E-Mu for a long time) said once "you can't model a train wreck".
This is one of the reasons people like samplers, is that you get all that
complexity.  It's much more difficult to change it into something else
unless you have the model of it available, with all of the "handles" to that
sound.   This model will of necessity be "lossy" in nature.
