Quote from: shawnb on September 03, 2012, 10:34:23 PMI have confirmed that the CC67 'soft pedal' controllers reflect the GR-55's Nuance settings on the MIDI bus. The GR-55's 'Nuance' setting reflects soft playing style, e.g., finger picking vs. using a pick. Higher values reflect 'nuanced' (slow) attack and lower values reflect a picked (fast) attack. In the MIDI spec for the soft pedal controller, 0-63 is off & 64-127 is on. I.e., the higher values should reflect a softer tone, just as 'higher' nuance values reflect a softer playing style. So the CC67s actually make sense as they operate. Note that these are on the MIDI bus whether or not the Nuance setting is on for your PCM tone (again, PCM settings don't have a bearing on what is on the MIDI bus - you could have one off & one on, what would it do?).

Quote..not the best combination for good results out of a GR-55.
Quote from: gumbo on July 06, 2018, 05:32:28 AMHmm......not the best combination for good results out of a GR-55.If you know anyone who has a guitar with a GK3 in it and can try it with your GR-55, have a go and see the difference.
Quote from: Chris71 on July 06, 2018, 01:01:55 PMHi Peter,Find the Ghost system an enigma. Sometimes I'm almost happy with it, sometimes want to introduce it to a ball hammer. Went with the setup with the stereo 1/4" output jack, so could still use the guitar normally in mono, or split it piezo-acoustic/electric. But recently getting this intermittent "swooshing sound" like a scratchy pot (or an actual Ghost ). It can go for an hour with doing it. Yes, checked the pots, the switches, the Molex connectors etc. but the guitar being a scratch-plate style makes it a biatch to fault find. It I run it 13-pin into the GR55, and at the same time whether or not I output the mag/acoustic signal from the back of the GR or use a 1/4" cable from the guitar, the "swooshing" thing doesn't happen.GK3 came with the '55, but never tried it as 1) didn't think it would fit in the gap on my RG's between back pup's and trem's, and 2) the scratch-plate RG I use with the GR55 was converted with the Ghost setup when initially had a $50 GR50. It had a GK2 that didn't think would fit either, so wasn't attempted.Obviously didn't do my research, but back in 2012 exchange rates were good so grabbed the Ghost setup cheap including the full GT Floyd saddles, I slotted the base plate on the IBZ Edge and it has been that way since. I've put all of the work into that guitar, so if the filter gets it done well enough, and considering my sporadic usage of the GR, I'll stick with it. A driver is a parts-guitar build I'm doing, with another full Ghost system ready to go into that - if I can't get the Graphtech deal working to my satisfaction in this setup, I won't bother using it in the parts-guitar build. Until coming here, didn't realise could install an internal GK3 setup. Does it still do the acoustic thing, or do I need a LRB, GT etc piezo system to do that additionally?Cheers mate.Chris.
Quote from: mmmmgtr on July 06, 2018, 01:18:25 PMI think the "acoustic thing" question was a bit unclear. Just to clarify....Please correct me if I'm wrong, but the GK3 internal nor the GK3 external do the "acoustic thing" natively. The GraphTech system, by nature of being a piezo system, can output an acoustic sound regardless of whether using a Roland GR55 system or not. To get an acoustic sound using a GK pick up you will need to use an acoustic model from the sounds internal to the GR55.

Quote from: admin on July 06, 2018, 01:06:18 PMInternal GK allows for Palm muting playing technique, and "does the acoustic thing" too - just need to to set the "GK TYPE" on the GK Processor ( VG-99, GR-55, GP-10) to "GK-3" the Ghost is notorious for being lots of hiss, noise, and poorest tracking hex PU.Internal GK-KIT-GT-3 are lowest cost herehttps://www.andertons.co.uk/roland-gk3-internal-pickup-kitand installation instructions are herehttps://www.vguitarforums.com/smf/index.php?topic=133.0
Quote from: Chris71 on July 11, 2018, 02:15:59 AMOT, what constitutes the ground signal for the mag pickups. Is there shield on the 13-pin cable/jack arrangement? There has to be a ground reference in there somewhere.Chris.
