another midi pickup question

[warwickben]

i asked not that long ago if its possible to buy on of those roland bass midi pickups and hook it up to a compture to run programs like reason.
wat i got for a response was that i need to buy some thing like axon 100sb or roland gr-20. i looke dat those and they werent wat i was really asking about.


i just want to know if there any thing i can hook the output of the midi picukup in to and it put sout normale midi so i can connect it to a usb/firewire midi interface.

It was me you asked. I gave a reply, and you didn't respond in that thread with any more questions - or even a thank you.

As I said then, to do guitar to midi conversion you need two things. Firstly, a divided pickup (or individual piezo outputs per string) . This outputs a number of parallel bass signals, one per string.

You then need a unit that converts your divided analog bass signal into digital midi information that can be used by a sound module or software program via a midi in. That's why you'd need an axon 100sb or roland gr20 or roland gi-20. Once that converts analog to midi, you can hook it up to your PC midi interface.

If there's any part of this you don't understand, ask away.

The Roland GR-20 has built in sounds. The Axon100SB has built in sounds also, there is a version without sound modules (AX100) which just does conversion. There's also the Yamaha G50, which as far as I know is a rebadged version of the Axon.
The GI-20 is about the cheapest stand alone convertor I know of, it's $350 new plus you'll have to buy a divided pickup on top of that.
I haven't used it, so I can't comment on it's qualities. Bear in mind cheap doesn't necessarily equal good with midi conversion, the Axon has the best tracking I've heard on bass.
