    I want to purchase a macbook, which has only one firewire port. I know that 5400 RPM hard drive speed is a little slow for recording, so I want the firewire port free for an external hard drive. I also want to buy a TC electronic Konnekt 8, which is a firewire device. I think it's possible to connect my bass to the konnekt 8, and then connect the konnekt 8 to the macbook's audio line in port using an audio cable. Will this yield results as good as just firewire? will there be more lag?

    It will add:

    - Noise
    - Distortion (not the good kind)
    - Conversion steps, which in addition to the noise and the distortion just mentioned, it would add even more noise and distortion.

    It will take away:

    - Headroom
    - Resolution
    - channel count (for individual control at least)

    In other words...
    Bad idea.

    Besides, the Konnekt 8 has 2 firewire ports. 1 is the output to the computer and the other will allow you to plug in your hard drive and work both devices simultaneously. The PCI/Firewire bus on the Macbook should be able to handle this with no problem.

    Cucco is there a reason why you cant use a USB external drive and connect the firewire audio interface to the firewire port?

    No reason at all. That would also work.

    I used a MOTU 828, daisy-chained to a firewire drive, for sevral years on a 1GHz Powerbook with no problems.

    Firewire 400 is fast enough, USB has to managed by your cpu, and doesn't have as high of a sustained data rate.

    You will need at least some sort of preamp for Low level signals that bass and guitars produce.
