Now, this IS interesting.

To do this the software must

-- detect the speed of the memory card
-- restrict the maximum stretch/shift ranges
    depending on how much memory == audio == loops == tracks
    the card can deliver at once.


example:

   Suppose some memory card can deliver the equivalent of 6 channels 
of audio at once.

   Then you could have four loops at normal speed (memory delivers 4 
channels)
   but not four loops at double speed (memory delivers 8 channels).


Does this make sense?


Of course, these ultra-low speed loops we are talking about before will use
up almost no memory bandwidth.


     This unit appears to have all sorts of charms.


MUSING:  Moore's law has memory getting 10 times larger every 5 years.

Full audio is 10 MB a minute.

Now: about $10 a minute for compact flash and $0.10 a minute for CD-R/W;

10 years pass:  about ~$0.10/min for memory, ~$0.001/min for disk
or ~$6/hr for memory and ~$0.06/hr for disk

RESULT:  If you had 100 CDs that were one hour long and you wanted
to bring them all in full form, you'd bring one six dollar disk, the end.

and that six bucks in memory will give you an hour of loops!


Imagine what a Repeater 5 might be like!
