Hi,

So I have a guitar with a Gk-2A pickup installed and I would like to buy a Roland GI-20 to trigger sounds of EWQL. Has anybody used this unit? If so how is the latency and will this unit run under XP 64?

I haven't used a guitar midi controller, but am considering buying one in the next year. I think you should also check out the Axon products (http://www.axon-technologies.net/) as they appear to have about the fastest response times, and are used by a number of professional players. The Burr Johnson videos (http://www.axon-technologies.net/modules.php?op=modload&name=Sections&file=index&req=viewarticle&artid=69&menu=10102) are worth watching and the claimed "early transient recognition" of 13 mS means that the latency should be about as low as is possible with a guitar midi controller. The Axon should work fine with the GK-2A.

I am pretty sure it does work OK under XP64, and Terratec staff were even asking which Op System users had here (http://www.axon-technologies.net/forum/viewtopic.php?t=1669&highlight=vista) on their forum. Perhaps you can ask a question there if you need a definite answer.

That unit looks so badass... only thing i wonder, does it have touch sensitivity?

Not sure what you mean here Javee ... aftertouch? Aftertouch can be assigned to the expression pedal so you control it through the pedal - I can't imagine how it could be easily implemented by playing the strings of a midi guitar. As for being touch sensitive, well you can bend notes and use dynamics in much the same way as you can on a normal midi keyboard. I think the best thing to get an idea of the level of control is to watch the videos of players using the Axon, but I was first impressed when I saw Burr Johnson demonstrating live at a music exhibition in London about 3 years ago.

As my main instrument is the guitar I have never been that enthusiastic at playing anything on a keyboard, and I would like to be able to play some of the EastWest instruments on a guitar - I think that would be really cool.

What i mean by touch sensitive, is that it senses your dynamics a.k.a. touch response. Electronic keyboards did not always have touch sensitivity or aftertouch. Seeing as the guitar as a MIDI instrument is still in early stage of development, I was just curious if it produced dynamics. When watching the videos i did not recognize any dynamics... the drums sounded pretty static.. he is no amature either.

As far as I can see the Axon does exactly what you are asking. I have watched all the videos (http://www.myspace.com/axontechnologies) I could find and they sound touch sensitive to me (there are a couple more on the MySpace site). I was looking for a midi guitar controller that would allow me to play instruments with the same sensitivity as when I play the guitar, and I believe the Axon does that. I was going to buy a midi guitar and an Axon last year, but instead spent the money on East-West products, but as soon as I can afford it I will be getting an Axon

Yeah i will be purchasing an axon system with midi pickup for sure. I could just imagine the ease.... I am not a bad piano player but the guitar is my true domain. I am very excited to pick one up. :)
