Yamaha PSR-350

I also included extracts of all 100 songs for your sequencing delight. With slight modifications to instrument mappings (or not) these
can be nicely used to test drive all kinds of GM-ish midi synth modules (especially waveblaster-type boards and other odd things).
For some reason I personally do realy enjoy running "wrong" demos on all the "wrong" synths that normally should have never
happened - like Roland XP-10 demos on PSR-230 and such.

SWX00B wave formats.
Some waves seem to have been intentionally lowpassed and made worse (all electric guitar samples, for example),
which is a typical market-differentiation practice by yamaha for various PSR-range synths.


Endinanness in your programming tools may be reversed.
To ensure that what you burn matches the necessary endianness, you'll have to dump
the old rom from your device through your tools and compare byte sequence with this one.
Swap bytes if necessary, and then burn that data.
