Works great with my midi controlled synths. I find it much more convenient as a bass player to be able to run my 12 step through a hardware synth. Currently use a bass station or an old FM Korg module for my extra bass tones. The soft synths are a great option but for now I'm using my modules.

Musical Background:

Playing for over 35 years on keys. Bass for over 20.

Musical Style:

Oldies, Rock, Pop
