I'd suggest a DAW (digital audio workstation). However, you'll have to make sure your computer is up to specs to handle these programs. You'll also need a MIDI/audio interface with DAW's.

Sonar, Logic, Pro Tools, Cubase, Digital Performer. etc... all do the same thing well. I use Logic Pro and love it. You'll need a Mac to run it. The others will work on any PC as long as they're up to specs.

You can Google DAW's to get the details and spec requirements on each.

Maybe a stand-alone digital recorder will suffice???

I'm sure you'll get more recommendations here.

Good luck, John smile
