As mentioned in List of plugins with tap tempo - #6 by falkTX - Plugins - MOD Audio Forum
We removed tap-tempo for plugins, being replaced by the tempo divider related options.
Only the global BPM can used as tap-tempo right now
So you set the global BPM as tap-tempo (by assigning it to the device footswitch 1 or 2) and then you can use the tempo mapping functions for addressing tempo-related plugin parameters
