New updates seem good to go so far just one minor thing I noticed.
Volcano still shows the ff prefix in Logic 10.3.2, El Cap for the mono version only.
volcano v2.31 (stereo)
ff volcano v2.31 (mono)
Thank for reporting this. Unfortunately, it seems that this one slipped trough with our latest update. It seems to concern only the mono version of Volcano 2. We'll fix this bug with a future update, its an easy fix. Sorry for the inconvenience!
Good to hear Maarten! Thanks for letting me know.
