Hi Paul and all,
a quick question regarding ardour's xml: after creating a new track,
inserting a LADSPA plugin, and saving, the .ardour file have an
AutomationList element like this:
<AutomationList id="5224" default="180" min_yval="1.17549435082e-38"
max_yval="3.40282346639e+38" max_xval="0" state="Play" style="Absolute">
Why these min_yval and max_yval? This LADSPA port is bounded by -180,
180. In case it is expected behaviour, what do they mean?
More misteriously, after some automations operations the min_yval
becomes 1 and max_yval becomes 3 (for all the LADSPA ports of this
plugin). However we have not found a deterministic way to reproduce this
I'm using the HEAD version of 2.0 branch
