To : Robbie Rhodes and all MMD readers.

Thanks for your interest in the MTP-1.

As the system stands, it has been designed to use a low cost micro-
controller, which is run to its absolute capacity. There is no facility
in the current system, therefore, for further expansion, so it can't
support system exclusives at the moment. There are, however, routes
available for expansion, namely to use a processor with a higher clock
speed which has more time to process the extra information. It would
also be possible to use a processor with more memory to support 'soft'
mappings.

However, as my original article suggested, I am anticipating that this
unit would be installed in an instrument where the mapping only has to
be defined once. If for some reason, the specification of the
instrument is changed, it would be possible, at moderate cost, to
replace just the microcontroller and thus enable the use of a new
mapping. This would be cheaper than buying a complete new unit.

Since this unit is in a very early stage of its life, any suggestions
as to alternative facilities would be welcomed - it may turn out that
there is more demand for re-programmable (more expensive) units than
cheap one- time programmable ones.

As far as code release goes, I am reluctanct to make any action at this
point, as there could be software revisions made as the demand for
features becomes clear.

Regards,

John Wale.
