Analogue-sequencer

Experimental types,

Another update is in the files section.
This one adds a new user config option -
'aux edit sets on' allows you to set whether or not auxiliary steps 
are auto-activated when you adjust the knob.
It also adds support for the wide-range PXPos value to the sequencer 
engine, and to the sysex handling, but doesn't yet have the UI to 
set it.
The sysex dump remains compatible - old dumps will load in, and the 
PXPos values from them will be used. New dumps will save wide range 
values (once you can set them !)

Some of the aux events have moved around in the list - watch out for 
any you may have already assigned.
The locations of these should settle down, but they won't be certain 
until all the proposed events are added. I'm keeping them grouped by 
type.
You'll find a summary of the current events in
'aux events-30-01.pdf' under files too.

Cheers,
Colin f
