I've had the FretTraX system for about a month now and it does deliver exactly how Lee the developer designed it. However it does take time to get adjusted when playing patches with quick attacks such as a percussive bass sound. You definitely need to adjust your technique and adjust the latency of the tracking depending on the patch. As for flutes, and such, it plays lovely right out of the box. Superb tracking. I was shredding in minutes doing my best Ron Burgundy impersonation lol. And shredding for me that is lol.
Remember this is a Fret sensing technology, not a pluck detection technology, so it doesn't track open strings. The notes need to be fretted in order for them to trigger. This system I believe was designed more for the soloist/tapping player in mind. With that being said I have had several conversations with Lee and provided him many suggestions and ideas for the groove oriented player, some of which came to fruition and luckily I have on my bass which he did custom for me.
I have mentioned to him that I am mainly a groove player, not a soloist and would love to see pluck detection added, which he has been working on. He also said that he has worked on some fixes for the occasional false trigger/chatter, and there are many other great things to come. The main thing that bugs me is the ability to play fast 16ths on one note. Since it doesn't do pluck detection, the only way to do this is to quickly Fret and de-Fret on the note which can be extremely difficult to do at a fast tempo.
I have gigged with the system a few times and it has performed flawlessly. I'm only using it on a few tunes throughout the night; songs I might add that I used to play synth on. I'm so glad I don't have to set up a keyboard anymore. Sweet! I am basically playing these tunes with just my left hand or for the fast stuff such as Bizarre love triangle by New Order, I've been using two hand tapping. It has worked really well.
I don't use it with my Future Impact. I am presently using it with my Alesis Nanobass and my Korg X5DR. I have tried it with the FUture Impact and it triggers fine, but most of my patches on the FI have bass blended in and need to react by how hard I pluck for the filter to open and close. I rely on the dynamics of my attack with my FI, something FretTraX presently cannot do since it is not velocity sensitive.
Even with these few hiccups, the FretTraX system is a great addition for my gig, and I'm happy I made the purchase, especially since I was able to add some custom options. Such as...
Vari channel which gives me The ability to change the midi channel of my bass... Two modes of split Fret which trigger synth above the 7th Fret and bass below and vice versa. Split channel which gives me the Ability to trigger two midi channels. One midi channel above the 12th Fret and another midi channel below the 12th Fret.
Lee Young is an amazing individual and truly listens to your ideas. It's been a pleasure working with him. Truly a gem.
I know some have asked for videos of the FretTraX system. I'm truly sorry I have not posted any. I have been swamped and just haven't had the time to record anything. I will try to do so in the near future.
