Guitar (hex) pickup into Max

Guitar (hex) pickup into Max

Hello,

I have a couple of questions for the guitar synth users:

Firstly, from what I’ve read a hex pickup such as the Roland GK-3 outputs 6 signals (one for each guitar string) through a 13-pin connector. Are these audio signals? According to various web sites they are, but I sent Roland UK an email to verify this and they said that it only sends MIDI data, which would mean there is an audio-to-midi converter built directly into the pickup.

Secondly, if they are audio signals, what is the best way to get them into a Max? I haven’t been able to find a 13-pin to USB converter type thingy. I know there are devices such as the Roland GI20 which will convert the hex pickup signal to MIDI then send it to the computer, but I’d like to get the raw audio feeds in if possible.

Thanks,

John

somewhere on the web there is schematics explaining which pin i swhich string

i have seen this page (many times) when searching things like
“guitar synth” etc – should be easy to find (with google)

ok, now i realise how incomplete my answer was

so

1/ the GK-3 sends audio plus some midi, from the switches

but it sends the 6 strings audio on 6 channels (6 wires)

2/ to get those in max i would use a 6 in audio intreface (with 6
preamps and/or 6 DI boxes) – some soldreing to get the 13 pins into 6
jacks……… (schematics on the web)

Roland UK is wrong. There is no MIDI send down the 13 pin, only power, six audio channels, and the knob & switch info.

Here’s one (of many) references to the pinout:

Thanks for the help guys, I’ll keep reading.

Chris, I didn’t even think to check unfretted.com, silly seeing as I plan on hooking up a GK-3 to my fretless :)

Call for Participation!
Registration is open to participate to our next workshop in Brussels,
11-14 October:

Laptop Music workshop:
Simple Genetic Algorithm for Music by Kim Cascone
The purpose of this workshop is to stimulate new ways of working
collaboratively and in performance with open source materials. Kim
Cascone’s approach is based on a simple genetic algorithmic which is
‘executed’ by the participants.
The concept for this workshop was inspired by John Maeda’s “Human
Powered Computer Experiment”. In this experiment Maeda recreated the
internal operations of a simple computer using people to physically
transport handwritten instructions and data to and from the CPU, RAM,
FPU, etc.
Participating in this type of experiment enables one to transfer
abstract concepts from their body to their brain. In a similar
spirit, this workshop develops a group workflow using the model of a
Simple Genetic Algorithm (SGA) with the result being an emergent work
of music/sound art.
The SGA workflow for the participants group is constructed as an
iterative process performed by the participants and working on a
shared pool of open source sound files (the gene pool) to which
fitness, matting and mutation operations are iteratively applied
until a collaborative work starts to converge.

About Kim Cascone
Kim Cascone has a long history involving electronic music: he
received his formal training in electronic music at the Berklee
College of Music in the early 1970′s, and in 1976 continued his
studies with Dana McCurdy at the New School in New York City.
In the 1980′s, Cascone worked with David Lynch as Assistant Music
Editor on both Twin Peaks and Wild at Heart.
In 1991, Cascone concentrated on Silent Records, a label that he
founded in 1986, transforming it into the US’s premier electronic
music label. At the height of Silent’s success in early 1996, he sold
the company to pursue a career as a sound designer and went to work
for Thomas Dolby’s company Headspace. After two-years at Headspace he
worked for Staccato Systems as the Director of Content where he
oversaw sound design using algorithmic synthesis for video games.
Since 1984, Kim has released more than 30 albums of electronic music
and has recorded/performed with artists such as Merzbow, Keith Rowe,
Tony Conrad, Scanner, Ikue Mori, and Pauline Oliveros among others.
Cascone was one of the co-founders of the microsound list,
http://www.microsound.org, which focuses on issues concerning digital
music and laptop performance. He has also published work for Computer
Music Journal (MIT Press), Artbyte Magazine, Contemporary Music
Review, and Parachute Journal.

I built a cable that splits the 6 audio lines from the 13-pin DIN plug
out to 6 1/4″ TS plugs, plugged them directly into a MOTU Traveler and
it works fine.
