    I really hope we don't get a touch screen. A touch screen belongs in my hands because every touch screen I've tried that isn't on my phone feels clunky and horrible. I must be in the minority who actually thinks that the Kemper UI is well thought out and very good. And as a UX designer, perhaps I should be worried!

    Yes. In cycle computers for example, the top models from Garmin etc have touch screens and resemble smart phones but are nothing like as snappy in response. New customers are often a little surprised that they can't navigate so quickly on one because it is slow to catch up. If you are going that way, you have a more fragile device with a clumsier user interface than the rotary encoders which are fast and precise. What isn't fast is stepping through 18 pages in the output section on the toaster. The editor fixes that. Generalising editing functions to more mobile devices than the iPad might be a good workaround. Support for iPhone and Android phone would make touchscreen based adjustments accessible to a huge chunk of their customer base.

    Maybe you have tried already but it is worth checking alternative connections. Sometimes a device will not work or be recognised when plugged into in a particular port or a particular cable starts acting up. It is worth trying other ports and cables.

    If you look at your hardware in device manager you can usually see that there are multiple USB hubs on a PC system. You might get some information about what is going on with the USB port you are using there. The other thing is that you can remove or disable a hub in device manager and then Windows will find it again after a reboot and functionality which has gone AWOL temporarily will return. I have followed directions of this kind from online windows problem solving sites (possibly Microsoft) to get a thumb drive going again but not the KPA.


    You have to have Kemper Kone mode enabled in the output section and connect your cab to the monitor out. If you are wiring 2 Kones for mono in a 2x12 you have to have them wired in series (4 Ohms+4Ohms = 8 Ohms) not parallel which would give you 2 Ohms - which is too low for most power amps and the KPA powerhead.

    If you are driving the Kones with a stereo power amp you can have two inputs on the cab with one Kone wired to each and that will give you 2 separate 4 Ohm loads which will be fine for most solid state and tube power amps. The older Kemper formats (Toaster/Rack) support stereo outputs for the Kones but you need to use the direct output for the second channel and you can't run a stereo FX loop if you do so. The Stage supports stereo Monitor out without losing any FX loop options.

    Best is to use a PC or Mac attached by USB to host the full version of Rig Manager that is hosted on the Kemper site. You can store all your rigs and audition them and edit them from Rig Manager.

    There is a recently released editor for the currently loaded patch that works with iPad via wifi for the Stage only. Some users are developing workarounds for the older (Toaster/Rack) versions of the KPA but these are not directly supported by Kemper at this stage AFAIK.

    I guess most of us have had occasion to spend time navigating through lists/folders of profiles in Rig Manager. Doing this means tapping the keyboard or using the mouse to step up and down a list of profiles or performances in Rig Manager.

    What if we had the option to use the foot buttons on the Remote/Stage to step up and down the list in Rig Manager or from folder to folder in the list? You could work your way through a set of profiles you are working with without even taking your hands off the guitar.

    This could just be an optional mode which would allow you to navigate RM in the same way you can navigate onboard profiles/performances . Activate it with a combination of switches and this mode would only operate when Rig Manager was connected.

    Excited for the ADA MP-1 pack. Which speaker/mics are in it and what power amp? Mine has been at a tech guys shop for a couple of months and I really miss it sometimes...

    Bert doesn't mention the power amp as far as I can see - Cabs/drivers include a Marshall 1960 quadbox with 4x12 Greenbacks, another (Mars) 4x12 with Blackbacks, a 1x12 with a Creamback H (Bert's cab), a Jackson Newcastle 30 cab and a Bogner 2x12 with V30s. So most of these will be familiar from previous profiling extravaganzas - IOW the usual suspects from Bert's earlier packs.

    The result of any Eq circuitry or DSP can be measured and recreated by convolution and deconvolution techniques. Think of cabinet IRs. All they do is enable us to recreate the complex frequency response of a guitar speaker.

    The static convolution method is unable to capture non-linear aspects of the response but it is debatable how critical those aspects are. Dynamic convolution techniques could capture other aspects of a cabinet response (or of the Imprints if they have non-linear aspects). There is some debate as to whether the results of dynamic convotion techniques are in practice any better than the usual IRs.

    I don't think any other company would be likely to take advantage of the above and piggyback on kemper's technology. They may be liable legally if they did and in any case they would be publicising a competitors work. So I guess the manufacturers will all develop their own incompatible brand of special sauce and hope that you buy into their product system.

    Standards allow interoperability and patentable tech can allow revenue sharing between the various creators. Quite possibly, there is nothing patentable in speaker response IRs or DSP code so unless it was directly copied rather than captured no infringement would be possible.

    Sounds like a locking issue to me. Is it possible to create a lock on effect in performance mode by double clicking as you did? I seem to recall that locking in browse mode and performance mode are separate things.

    I always hold down the lock button and see what is illuminated. I would try clicking the delay button (Y or Z say) while the lock button is down and then clicking it again to turn if off again. In other words try to deliberately lock then unlock it again to see if you can clear the lock.

    @ Halipino

    The whole performance is amazing. There are some good analyses of the performance on Youtube. They point to structured nature of the solo - a series of questions and answers and then out - and the way interest is sustained throughout.

    Are you saying Santana moved to a Kemper with these tones or he is actually playing that particular "real" amp?

    The real amps. Santana played Mesa Boogie from the early days of the hot-rodded Fender Princetons back in the mid 70s. He seems to have diversified a little in more recent times.

    Funny thing: In the most well known film of him playing live - Soul Sacrifice at Woodstock, he is actually playing this 500 watt Kustom solid state beast. He chose it just for the volume he thought he would need for the live outdoor gig with the huge audience.

    Having backups available probably saves quite a bit of grief for users and Kemper Support as the option to wipe the profiler completely and start with fresh OS and a recent backup of all content is there at hand for anyone who uses a computer with the profiler.
