I recently picked up a M-Audio Mobile USB Pre device from a local individual. It came with a driver disk but I had to download the latest drive from their website to work with Windows 7. Now my question is, what software (free preferably) can I use to play my guitar and record? I would like to have access to different effects and I hear Pro Tools is a good one but can't get access to it as it's not free or not available to download as a trial. Any recommendation on how to get the most out of this device? Thanks.
