I use to like hardware synths until I got this apollo 2. I use to think they were very responsive, easy to listen to and handy for setting up machines with strange sound cards. This apollo is a pain in the face. The volume dial has been dodgy since I got it, If the computer is under any kind of preasure it sounds choppy and in Windows its a desaster. I'd gladly fork out the money if I could find a decent hardware synth which was easy to listen to: was powered by USB, was very responsive and had an external volume control. If any one knows of such a beast please let me know. Darragh
