Hey,
I have a split GK3,
but it requires batteries.
Can I stream 6 streams of audio into my DAW with it?
I am screwing around with passive pickup and
home-brew audio-MIDI software,
and like the look of the thing.
If I can have 6 streams over USB, I am sold-
so, is this possible?
Cheers-have a ball w/- teh sounds

I recall admiralquality explaining how you would go about this Nick mate in a recent thread where someone was asking if it was possible to/or if there was a Roland VG/COSM plug-in equivalent available. So if you search then it should come up or you could ask the admiral dude.

Hope you are well and things are good, All the best your way as always Smile

Edit: Here you go, Hope i am understanding what you are asking man:

Thanks Dean,
My first post was bad at describing what I want to know.
Cheers again.
What I need to know is if the GR-55 acts as a soundcard and gives me the 6 audio streams from the GK-3 as audio--like the sound of the pickup--before any synth translation is done.
So I would have 6 audio channels show in my DAW over USB, that would contain the audio for each string.
Then I can do my own audio to MIDI conversion on them.
hmm, I'm getting one tomorrow, with 10 days to test it.
Hope u r lovin' the waves mate

Yes i am always loving the waves and distorting them. I have tried the GR-55 but that was not for long in my local which does not have a computer/recording department so i simply played it with a GK-3 equipped electric into a a regular amp/cab setup. I did not look into it any further but was quite impressed with it even though i am not a big synth sort of guy, It was alot of fun and Roland definately tightened things up IMO with the GR-55 and I am sure if memory serves we had a brief chat about it awhile ago in the 'your next guitar' thread IIRC with some videos of it in action posted, They did not contain more than a two part product demo though not anything in the way of technical detail again. I can not say anymore than that as i do not know. I hope someone comes along and answers/helps you out with the question. Enjoy the box when it comes as i sure did and as said it was maybe 40 minutes at best but good fun, So 10 days should be many hours of fun. Hope it operates/splits the way you want it to do. UncleE/Eric is always a good reliable source of solid information with the tech side of things as i am sure you know already. So perhaps he will know/worth sending a PM

Peace man and have fun either way, Catch up again soon bro

No, it doesn't do 6 separate streams, just stereo in/out. In fact the audio driver is pretty crappy, there's very little control at all.

Gibson was doing something like that for awhile too. I forget their take on it.

In order to stream it to your computer with 6 separate channels you'll prolly need a separate firewrie mixer not a usb mixer

Ta a bundle folks,
KVR never seems to fail when I have audio questions.
Polaris, thank you, I cancelled my trial, coz without this feature it is less fun 4 me, and doesn't aid my product development.
Tapper, keep an eye out 4 my conversion package, I will put video and audio demos up within the year. I am just now going to enqire about the price for a Fanout Box. Should be better not worrying about batteries running out, and I have my eye on a Godin Freeway SA to plug into it(already have the GK3). My breakout box is a little agricultural ATM.
Alternately, hopefully my Ubertar pickup bleeds little enough after I get some littler magnets for it.
My software seems to be doing what it should.
I need to set up an envelope follower to give velocity, and raid BertAnt's schemtics to try and implement pitch bend, but basically it seems OK. Latency is average around 1500 samples at 44100hz, which is perceptibly quite snappy.
Less for highE & more for low, it is diallable, any less and it starts to become innaccurate, but user will be able to dice as low as they like. All pitch detection is samplerate. Usine triggers the MIDI at around 7500 hz I think.
Sorry for waffling on so much, but i really like messing with this now 8D

tapper mike - Sat Feb 04, 2012 12:05 pm

I've got a freeway. It doesn't run on gk's it runs on ghost riders.
Ghost riders are like rmc's the are piezo. As a result you don't get oddball ghost notes and wierd volume /velocity shifts but what you do get is note cut off.

Muzik 4 Machines - Sat Feb 04, 2012 1:24 pm

one of my friend did separate the 6 streams frm the 13 pin cable, in 6 inputs of hus soundcard and made a reaktor/max ensemble to track the pitch/fx each strings separately

tapper mike - Sat Feb 04, 2012 1:45 pm

Honestly it's all past tense since I've gotten my ztar.

nix808 - Sat Feb 04, 2012 6:40 pm

I'll think about ponying up for the Godin, but I need to sort out the power supply-or is the Ghost passive?
I actually have one of those KMI StringPort units, not realizing b4 I bought it that it is Mac OSX only, thanks.
Mike, I hope you have satisifaction in ur Ztar, my software will be demoed in DIY before too long, if u r curious to pop in and check it anyway.
Cheers 8D
M4M, my software is built in SynthMaker and Usine. I have 2 hexaphonic setups atm, GK3 and Ubertar. I have MAX/msp, but can't really see that it would have any advantages over what I am doing currently.

tapper mike - Sat Feb 04, 2012 7:37 pm

The power is drawn from the box it is sent to Just like a GK A fanout box sends current to the 13 pin connector. Which is why a freeway SA does not have piezo audio out. Other Godin's use internal battery supplies such as the The Multiac Grand Concert (RMC) which I also own and The The LGX-SA which I thought about purchasing a long time back but didn't.

As far as Godin's go I always preferred fishmans for piezo.

Honestly I don't think you'll be getting any more out of it then you currently already do. KMI StringPort is really just a fanout box with power supply preamp and some other niceties like compression. I doubt if you will get both isolation and voltage/sustain.

Like I said previously where as gk's primarily get the signal from the string itself ghost riders and rmc's get more sound from the soundboard or top of the guitar. It means less ghost notes but it also means lowered output. It also means notes as you move up the neck have a tendency to cut off a bit more.

You get a ton of ghost notes with the GR-55. The Ghost system is terrible, compared to RMC and Roland's own stuff in terms of noise and glitching.

nix808 - Thu Feb 09, 2012 1:19 am

Thanks for the heads up Polaris,
I'll possibly try the Freeway SA,
but not for now.
The RMC Fanout is powered over 13 pin by whatever
box it is plugged into I think.
Yeah, sustain is a problem with these systems,
as Mike has pointed out.
You either have decent sustain,
or the strings don't retrigger when playing
successive notes.
My little magnets for Ubertar hex should be
here within a week.
Cheers 8D

Hi,

The RMC Fanout Box is no longer available.

I have a few designs that will record and play separate strings. (shameless plug).

Thanks bill,
Looks very cool.
If I end up trying the Godin, I may very well get in touch.
My littler magnets are on there. Yep-cut the bleed to a more manageable level.
I also got an Echo Layla for lower latency. Now can run on 256 samples, which is very nice. There is still the time to wait for the percussive pluck to settle down of course. Any suggestions for which soundcard would be even faster?
Now it's trying to get it to track perfect still-many small adjustments on band-pass and biquad filters.

billbax - Mon Feb 27, 2012 6:36 pm

Hi nix808,

Thanks for the lighting quick response.

I'm using a Roland VS-1880 for recording and playing separate strings, and occasionally use my M-Audio 1010LT PCI soundcard. There is no latency on the Roland VS ofcourse, although the latency on the 1010LT is quite good at 128 samples.

Most of my breakout box customers are using firewire interfaces, and getting very low latency figures. Saying that, I am quite happy with 128 samples on the 1010LT.

Big thanks to Meffy for putting the website links up! I didn't mean to spam the forum with a blatant plug, I just came across the Fanout Box topic on a google search, and so had to respond.

Regards,

Bill

Meffy - Mon Feb 27, 2012 9:58 pm

A single, completely on-topic plug isn't spam. *thumbs up*

nix808 - Tue Feb 28, 2012 7:42 pm

Yeah, no worries, ty
you have the solution to the query.
I will get one if I become dissatisfied with my 7-pin setup.
I have 2 firewire cards-
but 1024 is the best I can get on my Presonus FireStudio Project-
firewire mixer is on mixer duties.
Thanks for the heads up on M-Audio-- Will go have a look.
It's not a CPU issue.
My CPU is at about 8%--but still glitchy audio
to run clean:
1024 on Presonus(this use more CPU)
256 on Echo

I can make my programs run faster,
a little,
but it's not a CPU thing hmm

nix808 - Fri Mar 02, 2012 2:58 pm

boo-yah!
64 samples
I just had to turn off everything I'm not using-- in the mixer.
I'm a duffer!

Thank you SoundPalace
now 15% cpu

Hi Everyone,

I have bit of an update on the Fanout Box/Breakout Box and separate strings etc.

Just finished a demo on Youtube with separate strings in binaural 3D. I think it's well worth a view for someone who is considering a breakout box.

3D BINAURAL GUITARS WITH SEPARATE STRINGS

http://www.youtube.com/watch?v=N_vVU43Kz_w

The big question is, does it sound like 'real-life' 3D? In short, the answer is yes and no. You certainly have a sense of width, depth, and with a 'moving' automated sound, there's definitely a perception of 3D.

SEPARATE GUITAR STRINGS - ELEVEN IN TOTAL

* Extreme re-amping, re-guitar, effects, and individual string software editing.

* Guitar notes and chords are perfectly in key. Individual note quantizing is precise and velocities are optimised. Overall the all important performance 'feel' is kept in tact and greatly enhanced.

* 3D software plugin. With a binaural sound stage you have width, depth and height, so mixes sound more immersive than just simple Left - Right panning.

I hope you have enjoyed listening to this example of binaural recording with separate guitar strings...ahhh, the joy of hex!
