    the author (and some others) didn't get that the kpa is sold as a "profiler". the kpa's duty is to profile a guitar-amp-cabinet-mic-room-signal chain and to recreate that exact sound. it has some more options like adding effects and changing that sound in particular ways. and kemper is so kind to give away profiles for free to begin with. if you don't like them, make your own.

    the author compares the kpa to a modeler which can be judged by the accuray of it's sound replication of known amps.

    the kpa shows the world how difficult it is to create a good sounding guitar in a recording mix. it shows that the magic of a good recorded guitar tone is a result of a recoring engineers competence and isn't a matter of a 1-minute-setup. so thanks to all the great sound engineers that made, make and will make good guitar tone! :)

    I might actually contact him and talk to him about the conclusions he drew from his own user errors.

    everyone is entitled to their opinion, but publishing false info as facts (high latency) is not o.k., I think.

    hi don, how much is the kpa's latency actually and officially?

    latency between guitar strumming and hearing the sound through the speaker (sitting directly in front of them). Of course you have to add 0,3ms each m of distance between ear and speaker.

    ?? i use the switch 1 jack on the kpa's back with a volume pedal to control the kpa-wha... so you should be able to run 4 expressions at a time (2 fcb, 2 external connected to the switch jacks)

    Love this for another idea: i'd like to use my g-system in the kpa's stereo loop. to save some ad/da-latencies it would be great to use at least the spdif-in as a digital, stereo kpa-return (while still using the analog send of the kpa because the g-system only has an spdif output)

    oh cool. i, too, thought that different pus have a different impact on the profiling result, since they - beside their different eqs and dynamics - map different string/wave harmonies relative to their position on the guitar, which would be the input for the refining process.

    but ck knows that stuff better.

    i got a tc electronic g-system with a spdif-output only (no input).

    is it possible to put the g-system into a stereo-loop (mono send, stereo return) in the kpa's x-slot using the analog send and the digital spdif as stereo return?
    this way i could avoid da/ad-conversions with its' latencies.

    doing it all analog would use the following conversions:

    ad: kpa-in
    da: kpa-x-send
    ad: g-sytem-in
    (da: g-system-out)
    (ad: kpa-x-return)
    da: kp-out

    if all conversion stages were similar in latency (1,6ms), it would sum up to 9,6ms of overall latency. :S

    The volume pedal can serve as a booster since day one. It does not take a slot.
    When the RANGE is set positive, it boosts from the actual state, rather than attenuating.

    thank you for taking the time to respond and discuss.

    there are many possibilities to realize a boost function in the rig. but they all are based on sacrificing another important function.

    if we used the volume pedal for boosting (heel: normal volume, toe: boost volume), we'd loose the volume-swell-option. if we tried to use all functions of the volume pedal (heel: no volume, something in the middle: normal volume, toe: boost volume) there'd be a problem finding the right "normal volume", since a foot-based pedal does not give tactile feedback about the actual position (in contrast to visual feedback on keyboards' volume pots).

    a simple boost option (0-10db) with cc-switching in the amp/eq section would be a big benefit for live performances. :thumbsup:
    an additional boost-eq would be the icing on the cake for some.

    one part of it could be the lowering of the latency when using the detune or pitch shifter effects. i often use a detune (from pitch shifter) as a substitution for the chorus. but raising the detune results in an increased latency meaning unwanted (slap back style) delay.

    i made the following observation:
    if you profile a distorted sound and then roll back the gain to clean while playing the profiled rig, the dynamics in playing are too big causing the sound to be very loud and causing the output to digitally overdrive.

    i can easily imagine:
    if you put a distortion stomp in front of this arrangement the sound will be far too loud, since the stomp drives the loud clean and unsaturated sound into distortion.

    haven't tried yet:
    if adjusting clean/distortion sense has a big impact to this behaviour since i use clean profiles for clean sounds and distorted profiles for distorted sounds.

    my setup (for example) is: 5 basic patches that cover most stuff... one bank, instant access. if i want to solo, i just hit the boost (on my old g-system). if i made a second rig for every boost-situation, these 5 basic sounds (+boosts) would take 2 banks... ergo tap-dancing the banks when switching between those patches... and you would double quantity of rigs.

    love that idea.

    a switchable boost is a common things for guitar players... i think one of the most common things when playing live. some use it pre-amp to have more gain, some post-amp to just "be louder" while soloing. i'm the second one. some even like to boost all frequencies and additionally boost the mids a little more. a midi (cc) (foot)switchable boost, incorporated as an eq, could solve this without having to sacrifice one of the two precious stereo-slots (x and mod). but for me a boost (0-10db adjustable and footswitchable per cc) would suffice

    i know that you can create another rig for boosting... but a boost-switch would make things easier and cause less tapdancing

    I'd like to use an expression pedal and a double switch (additionally to the fcb uno), so far so good. (the fcb just does wah and volume and can't cover all slots/functions)

    - I'd like to assign the "x" slot (filled with a clean boost for solos) and the "tap" to the double switch. this combination is not available. a free assignment of these slots to either switch (1a, 1b, 2a, 2b) would be great and highly flexible.
    - I'd like to assign a free slot parameter (e.g. delay mix or feedback oder vibrato speed) per patch/rig to the expression pedal.
