Comments to certain host programs:

Fruity Loops Studio 4 and 5:
Not working:
FL Studio has its own method of assigning MIDI Controllers to parameters so you can't use ECS (External Controller Setup).
Generally MIDI-CCs are a bit complicated to route to VST.

Attention points / Tips:
Also the Pitch Bend range in the Channel Settings of Fruity must be 12 to not reduce the Pitch-Bend range settings of our instruments.
To save all settings of our instruments the wrapper must be configured to Allow program editing.

Sonar 3.x and 4.x:
Attention points / Tips:
If any problem should occur we recommend that you rescan using the VST wrapper, then select the reset all option before scanning as there can be several occassions that confuse the wrapper.
