I am well aware that ffp files can be managed like any other file. They can also be emailed as a MIME attachment or copied to a file-sharing site or an ftp server.
What you can't do is post the data on a forum or paste it into the body of a plain-text email.
A ValhallaRoom preset, by comparison, can be copied and pasted. Here's a VRoom preset:
<?xml version="1.0" encoding="UTF-8"?>
<ValhallaRoom pluginVersion="1.1.0" presetName="Big Perc" mix="0.497999996"
predelay="0.0890000015" decay="0.0551551543" HighCut="0.502013445"
earlyLateMix="0.802999973" lateSize="1" lateCross="0.200000003"
lateModRate="0.262626261" lateModDepth="0.270000011" RTBassMultiply="0.693333328"
RTXover="0.225252524" RTHighMultiply="0.533333361" RTHighXover="0.477852345"
earlySize="0.287087083" earlyCross="0" earlyModRate="0" earlyModDepth="0"
earlySend="0.5" diffusion="0.800000012" type="0.333333343"/>
Highlight the preceding XML text and press CTL-C. Open VRoom and select "Paste from clipboard" from the Presets dialog. Just like that, you can get a preset from another VRoom user.
