[Jsynthlib-devel] Method to pack/unpack 7-bit bytes to/from 8-bit bytes?

[Joe E. <jo...@em...>]

I'm reading the sysex spec on the Alesis SR-16 drum machine.

Since it uses full 8-bit values in for some settings, it turns each set 
of 7 8-bit bytes into 8 7-bit bytes.

Seems like it would be something that happens in other synths. Is there 
already a function in JSL that does this so that I don't have to write 
it again?

The Alesis DM Pro driver uses the same method, as does the QS(?). It's not 
shared though, perhaps it should be?

The org.jsynthlib.plugins.Decoder class is designed for sharing this
type of functionality.  However, it would probably be difficult to use
outside of an XML driver and XML drivers aren't very useful until the
XML Editor support is finished.
