Hi folks I got the ESI Gigaport HD+ that I bought for a specific purpose and that is to route 4 digital stereo audio files from the hard drive and output them simultaneously yet independently via its 4 stereo analog outputs (or 8 mono outputs) to an analog multi-track tape machine for recording 8 separate tracks on tape.
I learned that I need to install ASIO4ALL multi track plugin but I need a software that allows me to lay down my 4 stereo files (8 tracks) and stream them to the ESI Gigaport while the deck is recording in real time. Note that I'm not looking for any DSP functionality or any kind of feedback or loop, just straight routing, 4 digital files in, 8 analog outs.

Any easy to use software out there that don't require breaking the bank?
