I've been looking into using one of these programs as a main multi-track recorder. I have a Tascam HD-P2 that I use for bag work and will still use as a backup recorder. I downloaded the trial of Boom Recorder but I'm having some problems with a nasty crackling, robotic sound. Right now it's running into the computer through my Onyx Satellite but I have an Onyx 1220 mixer that I will be shortly getting the firewire card for to use as my main interface. Has anybody had this problem before? What's the general feeling of Boom Recorder vs. Metacorder as Boom Recorder is significantly cheaper?
