Let's try the common way..
To record a soft synt track :
Insert - Soft Synth - VST2 - Kontack
check these
- simple instrument track
- synth track folder
- enable midi output
- synth property page
- synth rack view
default checked (that i never change)
- recall assignable controls
- ask this every time :)
.. I hope this will get you back on track. Perhaps you were adding a midi track, then manually insert a vsti in the FX ?
