Hi all,

I'd like to share some experience on using the GP-10 and kindly ask your ideas on it.
I downloaded some patches from Ainsoph, which are great. Preparing for the rehearsal I tweaked the e-piano patch.
-To mask the latency I mixed in the real guitar sound in order the get a direct attack followed by the e-piano. The pedal I used to control the mix. But the sounds of the synth and the guitar don't really mix, that is tones (higher harmonics) are a little off between the two.
- I tend to dampen a lot with my fretting left hand. Playing the guitar it isn't noticable but the synth detects a new, lower note. It cannot be get rid of much of that artifact by setting the velocity. I'm considering of (re-)learning to dampen with my right hand more.

I'd gladly here your ideas. Maybe from users of other synths?

I don't have much of that issue, maybe from playing a lot of midi guitar in 80-90s, but low velocity cut and some of the amp and filter velocity sense settings can help some.

Hi Brak(E)man,

Thanks, I'll give it a try. Maybe I should learn to accept the latency. Admin also suggested in another reply to roll down the highs on the real guitar.

There's also lots of patches that's based on wave synth and gr300 synths.
They don't have those issues.
I suggest checking them out.

Yes, that's an option. Now the OSC has more option to change the sound and I'm trying to come close to Michael Brecker's EWI solo on In a Sentimental Mood  :)
Or am I missing something?

There's more possibilities sonically with the OSC synth but the wave synth is zero latency and there's lots of sonic potential.
Here's a couple of mine but there's loads of patches to explore.

Check https://www.vguitarforums.com/smf/index.php?topic=26618.0 for a solo sound

For pad based on GR300 also zero latency

Hey Brak(E)man,

These are wonderfull sounds! Thanks for sharing.

So progressing on my quest for more control over the OSC synth, especially on Ainsophs e-piano patch, I found a discussion in the SY-1000 section (don't know how to link them here) that adressess this topic also: unwanted and off sounding notes.

I connected the GP-10 with Ableton and made a recording in which each string is recorded seperately playing jazzy chords. What I found was that
- the hex pu- elements pick up from adjacent strings (cross talk). So same frequency on adjacent elements.
- strings sometimes resonate with adjacent strings. (Resonance). Sometimes the same frequency, often one octave below or a harmonic,especially when the lower strings are involved.

All these off-notes trigger the OSC with these lesser result. They also trigger the jamorigin midi vst in Ableton so it is a generic audio to midi topic, not gp-10 specific.

I thought off what can be done:
- playing style:
not playing to loud,
dampen strings that should not ring, especially when releasing a chord.
But than there still is the transient. So also not fretting nor hitting strings that should not ring. Basically plucking. Which for me is unlearning jazz and funky comping.
- put a damper near the headstock end of the strings.
- a noise gate before the OSC preferably for every strong seperate.
- adjust midi velocity

I'd appreciate insights from others on this.

Low velocity cut as said
Also lowering GK sensitivity settings.
Right and left hand damping of strings are a huge part.
Depending on what hexpu you have, the crosstalk varies a lot.
In general piezo is worse than a magnetic GK.
The OSC synth in SY-1000 is much better in most of these areas though.
You can listen to this example.

The gtm settings are a story on its own but shares some/most of the OSC issues.

Thanks Brak(E)man,

I use a GK-3. Lost all the detailled settings of the hexPU by thoughtlessly resetting the gp-10🙃.

#10
Reduce adjacent string crosstalk with GK-3

Verify the physical placement of GK Pickup is correct.
Refer to official documentation here
https://www.roland.com/V-Guitar/about.html
https://www.roland.com/V-Guitar/gk3-requirements.html



GK PU MOUNTING LOCATION
Verify there is roughly  20mm distance from GK PU to bridge. GK PU mounted Closer to bridge reduces the string output and not recommended. GK PU mounted further than 20mm increases susceptibility to adjacent string crosstalk - owing to wider excursions of each vibrating string further away from the bridge, which  may invade the adjacent middle four  A D G B string GK Pickup flux field regions- particularly when string bending blues styles.

GK PU HEIGHT : a general rule of thumb, use the included spacer to adjust the GK pickup height so that you have a space of about 1.0 mm between the top of GK pickup and the bottom of 1st and 6th strings when these strings are held down at the highest fret.


Lower the GK String Sensitivity

The default GK String sensitivity at 65 may be prone to crosstalk on some guitars

I always start by lowering this to the 25 to 35 range-for a balanced output across all strings.


There are no rules - get creative

On some situations with GK-3 pickup -try setting GK Type to one of the Piezo types - each type has a unique EQ curve and provides user Adjustable Bass and Treble controls


Don't forget to read the Setup docs for other GK Processors(VG-99 & GR-55)
- as the lower cost GP-10 lacks specific knowledge base reference documentation  that would cover same ground deep dive documentation provided for VG-99 & GR-55
