I'll add my vote to that! However, if a separate branch is thought necessary
for good reason, all well and good - but at the very least it must be named
something other than 'BlackBox'. Just calling it v2.0 is less than
satisfactory and highly confusing.

OuS have demonstrated they are willing to accept good solutions to problems.
e.g. see Alexander Iljin's blog:

What sort of data transfer rates are you trying to achieve? I'm no expert in
all aspects of this type of programming but I have had plenty of experience
of the challenges of recording audio on Windows at ~170Kb per second without
interruption for up to three hours continuously (I'm using Delphi rather
than Component Pascal for that particular task). This sort of data transfer
is usually done by device drivers communicating with Windows at the hardware
level and the Windows message loop being used by the application to transfer
the data from the device driver to itself. Is that the approach that you are
using or are you trying to control all of this at the BlackBox / application
level?

Agreed - *any* activity and efforts intended for the advancement of BlackBox
and Component Pascal are welcomed!
