It might be MIDI because you can have MIDI over USB, and the HD500 appears as a MIDI device even though it doesn't expose the physical MIDI ports on the HD, so you can't use the HD500 as a MIDI interface. What is probably happening is the HD Edit interacts with the HD500 through SysEx MIDI, but Line-6 haven't published any information about how it works. It might be possible for MIDI Ox or something like it to monitor the messages on the HD500 MIDI Device, in which case you might be able to reverse engineer the interface specification, but that might be rather a long a job!

It won't. The CC messages change the state of the switch, which is the same as you physically pressing it. The lights are still connected to the first effect that is controlled by that switch. Send the CC to a switch that nothing is controlled by and nothing will happen.

I think you will find the ideas I referenced are all for at least a separate cab and mic block from the amp

Its a good idea, which is why it has been thought of several times before - Meambobbo had the two amps set the same for different cabs and mics in his high gain guide and discussions ran from there - he also had to fake the time delay problem by using a flat eq to delay one path or the other so that they stayed in phase.

You are caught by the default MIDI Patch change message - the HD500 send a Patch Change on it's default MIDI channel (1) and the H9 is also listening on it's default MIDI channel (also 1) and changing patch in response. The only "always works" option was to change the default MIDI channel on one of the units to 2, and then explicitly set a switch in the HD500 to send a Patch Change on Channel 2. However the H9 has a MIDI Program Change Receive Map (apparently, I don't own one), which means that you can define what the H9 does when it receives a PC message: [RCV.MAP] – Create a MIDI Program Change Receive Map MIDI maps are an efficient way to instantly recall any of the H9’s Presets using your favorite MIDI controller (pedal board, sequencer, etc.). Press the HOTKNOB button to select and create a MIDI Program Change Receive Map. This function sets the corresponding Preset that is recalled when a MIDI Program Change message is received. (Referred to as Prg No. from here on.) So you don't really have a problem, just need to do a bit of fiddling on the H9. It appears that devices such as the Line 6 M5 can also do the Receive Map trick as well:

Some lefties play right handed guitar upside down - Hendix could, Albert King, Otis Rush, lollipop Dale and Doyle Bramhall II And many left handers just play right handed - does seem to have caused too many problems for Duane Allman, Mark Knopfler, Danny Gatton, Billy Corgan, Michael Bloomfield, Gary Moore, Tony Iommi, Joan Jett, Steve Morse and Noel Gallagher. Don't know what you are complaining about Says a right handed player.... :ph34r: :ph34r: :ph34r:

You can do it, but you have to use the Variax Mags for the electric. Set up the patch with Variax on one Input followed by whatever effects you want, and Variax Mags on the other Input followed by effects and amp as desired. Make sure that you have no effects placed before the split - especially mono ones otherwise it won't work

I think that this is the work-around - if you have an HD 500 you could disable guitar volume and control Amp Gain and EQ settings with the JTV Volume control - it may not work for every amp (some of the high gain ones still have volume when gain is 0 and the mid treble EQ may be wrong frequency), but it will probably work quite well with some of them for no cost in FX slots

Steve Rothery of Marillion used a JC-120 on pretty much everything I have say my concern however is how much of that "shimmer" sound involved the Vibrato or especially Chorus effects. Anybody know which switches on the Dimension model might give that subtle shimmer?

It makes no sense for it to be mono.. the HD500 is a stereo unit, so must have a stereo Global EQ. It also only makes sense that it should have an on/off (bypass), as otherwise you cannot compare before and after while setting it up. As one of those who asked for it, my rational was that I am going to a PA speaker that doesn't have EQ and which is acting as backline, therefore actual sound varies depending on room and where it is placed. Global EQ is about getting that speaker, back to a flat setting so that I sound good on all patches. It is not about varying for each patch.

Get that Workbench open... you can redefine what the alternate tuning definitions are, so you can easily change your guitar to have your preferred version of the tuning. Or just do the patch specific alternative tuning using the HD500

This is fairly good summary of 4K TV: http://www.techradar.com/news/television/ultra-hd-everything-you-need-to-know-about-4k-tv-1048954 The next resolution is 8K TV, but you need a 84"+ TV to appreciate the improvement.

As I read it, it is just a dedicated remote control for a KPA unit, not an effects unit in its own right and the looper function that it adds is all of 30s. If you have bought into the KPA, then a dedicated remote is a good idea because it integrates properly, just like the one for the Axe FX http://www.fractalaudio.com/p-mfc-101-midi-foot-controller.php Both are priced for their market mainly I expect due to the low volume of sales expected meaning that each unit has to include a high level of development costs

My understanding is also that VDI includes a simulation of a cable. (and the HD500 Impedance setting is real and only on the Guitar Input) Not certain that it is connected, but you can hear the filtering when you lower the volume knob as the tone gets less bright - which is what happens with the real equivalents. If using a normal guitar and old wireless link with a short cable then the tone remains bright as the volume is lowered. Depending on how much you use your Tone knob (I know many people have never touched it!) you can program a slight reduction in the Tone setting from the HD500 against each patch and lock the Tone knob so that when connected via VDI it is always say 80% Tone. If you also tweak the Tone Resistance and Cap setting in Workbench you can probably get exactly what you want.

I know that I have said this on other threads, but a small headphone amp (1.5" square) such as Fiio E6 does this job perfectly and certainly improves the tone into my Westone IEMs (http://www.amazon.com/FiiO-E6-Portable-Headphone-Amplifier/dp/B005HJWWW8)

the HD500X can be programmed to send CC commands when FS1-4 is pressed Yes - most of the switches can be programmed to send MIDI If I assign a CC msg to FS1 and have FS1 default "on" for a given patch, does that CC command get sent when I select that patch? No - you can't have FS1 default to On, it just doesn't work that way; FS1 might be linked to an effect that is On and this is reflected in the light against the switch, but that is not the same as the switch being pressed when you change patch. There is no way to send a MIDI message as you go into a patch other than the default (and unchangeable) Patch Change However if you only have a limited number of patches, and run in ABCD mode, then you can have a single CC message sent when you press the ABCD switch to change from a patch; the MIDI definition on the HD500 will need to be on the patch you are switching from not to.

Get a little headphone pre-amp such as the FIIO E6 http://www.amazon.co.uk/FiiO-E06-Portable-Headphone-Amplifier/dp/B005HJWWW8 (if you are using 1/8 sockets), not only does it include a volume control that allow you to run the POD at full but it also can solve impedance matching issues and improve the sound in the headphones.

What are Inputs A and B set to? Default is every source on A and B set to the same. If Mic is included and the trim knob is up the Mic input can generate quite a lot of hiss, so you should remove all unused sources from the inputs list to minimise noise. Change A so that it is only guitar and B to Same or Variax (depending on the input level you want - same gives double the level)

Have you got the latest HD Firmware? - support for saving L2 modes was only added in version 2.1

The discussion is about potential latency from a longer USB cable which like all communications signals carries an analogue signal that encodes the digital signal. There is no such thing as a 1 or a 0 over a bit of wire, there are voltage thresholds over and under which the voltage being received is interpreted as being a 1 or a 0. As I said at the end, you have to go over 5000' before you get a single audio sample of delay and I'm not carrying that cable in my gig bag.

:) Sound travels 1,129 ft/s (Wikipedia) which is 13.548 inches per millisecond, roughly varying with pressure, temperature and humidity. Millisecond to nanosecond is divide by 1,000,000. 2ns/foot as pfsmith0 says is a typical speed for a electromagnetic wave down a conductor (which is between 40% and 70% of the speed of light) So my figure is only for the delay of 1ns caused by an additional 6" of cable, but I was rushing a bit. The 16' chord is 10' longer than the 6' chord so adds a 20ns delay, which is the equivalent of moving the head just 20 x 0.0000135 = 0.00027 inches further away. Yes, technically the extra cable length does increase latency, but by an amount that would only be noticeable when examining the waveforms on an oscilloscope (sound at 1K has a wavelength of over 1'). I practice we are talking digital sound, and at 96K sample rates each sample covers 0.0000104167 of a second, and 20ns is 0.000000020, so you would need over 5000' of cable to delay the signal by even 1 sample.

Tell John to move his head 0.0000135" closer to the speaker then.
