[PD] midi button logic problem

[PT147 at mdx.ac.uk]

Hi Anton,

You could use a 'select 127' object routed to a toggle.  Unfortunately,
you then have the problem that the duplicated messages would instantly
turn the toggle on then off.  I've included an abstraction with a
workaround, anyway.

Cheers,

Peter
