    what is firewire
firewire is a serial bus interface for the transmission of digital data. introduced by apple, its standard IEEE1394 is designed for multimedia application such as camcorders or multitrack audiodevices. a transfer rate of 400 MBit/s makes it ideal for real-time applications. IEEE1394 is 'hot plug & play', meaning an instrument can be plugged in or removed from the computer while running. devices connected by firewire are automaticly activated and operating power is supplied through the single cord. the term 'firewire' is in no way related to protective measures such as 'firewall'.
        


    guitar to computer
the electric guitar holds much more potential than the standard jack is able to transmit. this is not surprising, as the jack plug is based on a telephone technology more than 70 years old. computers have meanwhile become standard appliances in offices, homes and studios. their enormous capacitites allow the full rendering of the hidden potential of the guitar. who, in the early days of the electric guitar, would have foreseen the rock revolution? i consider the firewire guitar to be the start to a similar opening: no-one can foresee to this day how far creative minds will go with it. some amazing features and promising ideas have already become reality:


main features firewire-guitar:
A/D converting 24-bit / 96khz
12-channel guitar-out
2-channel return (headphone-monitor)
midi-data remote control

Boy, I sure do wish this would hit the market in a larger way - I recall 3 or 4 years ago - seeing the board for this guitar down in Hall E at NAMM (wasn't that the same board, Elantric...you saw it that year, didn't you?  Don't I recall us talking on that?).

The problem with firewire, USB and even Roland GK type alternate connectivity is that they don't support wireless. I think most performing artists using an active stage setting would prefer wireless these days. Someone is bound to develop something that also supports wireless one of these days.

Ahhhh! Speaking of this (wireless) -- has anyone run a wireless connection to the RIP box and then to a hexaphonic interface (like the Roland)?

Precisely my point. Don't think it will work. You need the stereo signal carried over the air. Any decent stereo wireless kits for guitars?

Correct, no Hex Out via wireless.

But you can use Dark Fire with standard wireless guitar systems - but its mono only.

Looks like I need to buy a Dark Fire just to see how it works;-)

So the connection from the guitar to the RIB is a stereo cable? Is the mag output on one channel and the serialized piezo on the other?

Could you do a stereo wireless system with two mono channels, each at different frequencies?

(Inquiring minds and all that:-)

Thanks,

The Multiplexed out is on the TRS Ring

But it requires a signal distribution system with a frequency range of DC to 40khz  so that rules out a standard wireless guitar system - they are typically 40-18khz

Looks like the Dusk Tiger will have some type of Firewire connectivity -- I assume this will be out of some type of breakout box, but really haven't seen any details yet.

(And assuming it is like the other Gibson "cutting edge" guitars, I won't know until E reverse engineers the sucker;-)

Update on Rolf Spulers "Paradise" Firewire Guitars
http://www.rolfspuler.com/gb/index.php?option=com_content&task=view&id=20&Itemid=120&limit=1&limitstart=0































These are the controls - Linear slider pots



standard: two slide-potentiometers for master volume and polybass
optional analog: pickup switch
optional digital: two slide-potentiometers for continuous MIDI controls, program switch
optional guitarmidi: slide-potentiometer for synth-volume, S1/S2 program up/down switch[/i]

Connections

The standard jack output presents the entire guitar sound-mix of bridge pickup, polybass and the optional sound sources. with a stereo plug the polybass is separated. in firewire mode the ¼” jack connection turns into headphone monitioring, delivering the full sound mixed in the computer or desk. the firewire bus supplies the guitar electronics with power and shuts off the batteries
          

Firewire (optional)

Equipped with the firewire card the guitar goes digital. it can be connected directly to a computer or my spacebox.  so a new sky of sounds and musical expressions gets open: each string signal can be modulated and recorded independently. controls on the instrument trigger software parameters such as filters, volume, program changes and the like.


          

13-pin guitarmidi (optional)

A guitarmidi card expands the paradis to midi. an optimized circuitry with 13-pin connector drives systems by roland and axon to trigger synth-sounds. the controls on the instrument are assigned to midi volume and up/down program changes.
          
Battery


The noiseless studio electronics are powered by 4 AA type batteries for up to 20 hours. a led will indicate low power. the electronics automatically switch to standby after 4 minutes of inactivity: no more battery runout because of a plugged-in jack! the circuit is reactivated by the first pick of a string.

This is a reply from Rolf Spuler today:

hi there
i am surprised people here remember my firewire guitar project. so let me keep you updated:
i started the firewire guitar project in 2004, in collaboration with bridgeco. in 2005 we showed a first prototype at AES, based on bridgeco dm1000 processor. this chip allowed to transmit 12 digital audio channels and midi commands, but its limited power didn't enable pitch-midi conversion. in 2006 we formed an engineering team with terratec axon people and designed version2 guitar-interface, based on bridgeco dm1500 chip. its capability allowed the implementation of axon pitch-midi algorithms (belong all features of V1), we presented a V2-equipped guitar at NAMM2008. it run a powerbook with plogue/bidule audio host and mathons polyphonic vst plugins. cool stuff ahead of any other software, although not perfected. immediately we started V3 as a commercial version - small format that fits standard electric guitars. it was agreed its a terratec axon product, called axon diguit. we concentrated on oem and contacted most major guitar companies, such as fender, godin, line6, ibanez, yamaha, washburn, carvin... then a patent collision blocked our advance. none of the contacted guitar companies screwed up courage to enter this delicate hightech niche market with view up to patent conflicts. it is much easier to make money dealing standard strats :-)
early 2009 terratec run into serious finacial troubles and stopped the development of axon diguit and further axon projects. axon people tried hard to find a successor - neither gibson nor line6 were poised to pay a fair price for the axon legacy. also my tiny company was not able, and bridgeco sticked into problems too. in consequence axon and diguit died.
today i am able to run the V1 firewire version that fits my paradis guitar only. due to very few inquiries and the lack of development capital i decided to put this stuff in a box, waiting for better times.


for sure i keep on making guitars. creating beautiful and ingenious stuff is my
passion.
the firewire guitar project was technically successful - i'd be able to take it
out of the fridge at anytime. it's basically a question of capital. however i
suspect that firewire technology will be overtaken in a few years by a new
standard audio-over-ethernet. anyway our development was not to no purpose since
the transfer protocol is just one of dozens of components within the system.
probably the widest space for improvement is in the audio software part, where
multi-channel plugins are away from even thinking at major companies... my
friend matthias grob of mathons company programmed some hex-channel vst plugins
such as polydistortion, polypitch, polybass, polypan. for those who are keen to
take up with unperfected software, a download can be accessed by:
http://www.mathons.com/polysystem.htm

i currently work on a hex transducer system for acoustic guitars, for both
steel- and nylonstrings. a modular preamp consists of extension modules such as
13p-synth-acces

Its just amazing. Put aside the technology side, the design & craftsmanship on that guitar is absolutely astounding. The use of slider pots is so simple yet fitting...
