Thank you.
This clip is the M Britt, Marshall Silver Jubilee 1 8. I increased amp definition to 9.8. First riff is my Les Paul in the treble position, second in the middle position and last in the rhythm position.

No Post processing.

Guitar - Kemper - RME Fireface UC (spdif) - Reaper.

I've tried all the profiles that came with the Kemper, the free M Britt, TopJimi's, purchased a couple of M Britt packs. Plus Mix Berlin Marshall JCM 800.

Here's a comparison test:

Same profile with Ibanez RG652AHMFX-NGB (bridge pickup). Amp definition was 9.8
Guitar - Kemper - Scarlett 18i20 (spdif) - Reaper.

First is your clip (treble position), second is my clip and the last is both together panned to the left and right

Frequency comparison
blue = the frequency response from your clip,
white = the freq response curve from my clip

Still no success...I wish the MIDI documentation was more detailed - covering this part also.

If anyone has any knowledge of the subject, please post here. Would be nice to know if I'm just doing completely useless "coding work" here

So again, this is what I've tried to do:
(I'm using ReaScript Lua and REAPER JSFX)

• I have a Lua script for reading sysex data from kipr files (kipr file header and length bytes after F0's are ignored)
• Lua script sends the data to a JSFX array
• JSFX sends the data to KPA (One complete message per "sample block". This can be changed)

help, why my Toast Me is different from yours

That looks like an empty Ctrlr panel...try to download the Toast ME again from post #1.

I tried sending cabinet presets (kipr files):
[Blocked Image: https://stash.reaper.fm/33872/KPA%20cabinet%20data.gif]

Data structure for these presets:

• 16 cabinet tag messages
• 2 BLOB messages (only the first one changes between presets)
• 1 multi parameter change (always same)
• 1 extended parameter change (always same)

I still can't get this to work
It seems to work when I first send all the data (except header and length bytes) -> store cabinet module (by pressing the store button on KPA) -> browse back to that module, but storing the cab would be an unnecessary/pointless step because I'd like to apply cabs/amps directly from kipr files. It should be possible, but I can't figure out how to do it.

Applying presets (cabs/amps/FXs etc.) from other rigs or preset files would also be a nice feature for the Toast ME

Do I need to refresh the rig by sending a certain sysex message?

Just bought the US Duality pack, very nice demos!

"ENGL Invader 2" -pack would be great...

Quote from szykman

also is impressive that kemper has this midi chart so complete and friendly for third part developers, thank you kemper too.

Everything UI-related is very well documented, but there are a lot of stuff that isn't documented at all (e.g. "Lock module/section/parameter" is not documented):

Here's a couple of very important/mandatory "API functions" that most probably exist (because Rig manager uses MIDI for data transferring), but aren't documented:

• get current rig as sysex data (also when in preview mode)
• set rig from sysex data
• get a list (filenames) of all stored rigs in KPA
• set rig by (KPA)filename
• get amp/cab as sysex data
• set amp/cab from sysex data
• get presets/preset names as sysex data

Also, I wish there was an example for BLOB messages:
How to send BLOB parameter changes (KPA seems to ignore them)

I'm trying to store rig data directly to tracks in REAPER DAW (there's ReaScript API that makes that part possible)
Then, later when needed, I would like to send the data back to KPA...

This is what I've done so far:
(Kemper file header data and length byte(s) at the beginning of messages are removed before sending data to KPA)

Everything else seem to be working except BLOB messages... UI-related parameters are working, but the actual core of a profile (amp/cab) isn't.
Is there something I should know? Should I notify KPA that there is sysex data incoming (by sending some "enable sysex communication" -message to KPA)?

(from the KPA midi docs)
BLOB Parameter Change
A number of parameters do present binary objects (“BLOBs”). These BLOB parameters do have their
own batch of controller numbers. They exist in parallel to the numeric and string parameters.
The content of a BLOB is per definition “off hands” and should not be altered.

Quote from Smirre

Nice! Gotta try that myself too if i ever get my hands on a treble booster.

I used Kemper's treble booster. (I just lowered the Tone parameter a little bit )

This is really good, thanks!
I just replaced the pure booster with the treble booster to bring more highs in - seems to work very well

Zoom U-44 is probably the cheapest (109 euros) audio interface that has MIDI I/O and even optical/coaxial SPDIF input and output.

Thanks!
It seems I have already tested this, didn't remember :
KPA DAW SAVER > A little plugin that can save current rig with your DAW session.

Damian, do you still have the panel file for your KPA-DAW-SAVER? (there's only "dll" files in the "rar" file)

Very nice work!

There's a new feature added on the latest OS update - UI to MIDI. Adjusting knobs on Kemper sends MIDI data when it's enabled. That could be useful for reducing MIDI traffic.

Damian, you might know the answer for this:
Is it possible to get current rig (as sysex data) from Kemper? Is there a magical sysex string for that
That would be so useful when combined with REAPER's ReaScript API. It would be possible to store rigs per-track, per-item or even per-take and later recall them...

Seymour Duncan 805 Overdrive

It's supposed to be a "transparentish" OD with 3 band EQ.

This is just a test, but sending/receiving sysex data seem to work ok:

Web MIDI API (https://webaudio.github.io/web-midi-api/)

I'm getting DSP communication errors with FW 5.4.0.13150 and FW 5.3.2.13089.

Reverting back to 5.3.1.13085 fixes the problem.

It happens here too.

Thanks for the detailed info!
Do you happen to know any details about the bass - is it an amp or a KPA profile?

I just had to buy this profile pack after hearing this clip, thanks!

Hey guys, I just wanted to chime in here... sorry, a little late, was on vacation!

Finn's clip on the OP are great!

I too had the chance to test drive Tim's 6160 profiles. Great, versatile profiles! There is some very unique stuff in there. The profiles with the Celestion Blue speaker are quite interesting and different from what you would expect from this amp. I recorded a short clip (see the ballad clip posted by Tim earlier in this thread). Guitars used were a Tele with CS 51 Nocaster pickups and a LP with a Suhr DSH+ pickup in the bridge. Profiles were used as is on the recording - just rev/delay added at mixing time, no EQing nor tweaking of the profiles.

Thanks for the great work on these Tim.

Thanks for the great clip! Do you remember the exact profiles used in the clip?
That bass sounds very good - is it possibly a KPA profile?

Quote from soulrebelno1

Is this what you're after?

I've tweaked an Engl E670 SE amp profile by Tony McKenzie from the rig Exchange so there should be no problems importing it (see zip attachment).

To get the sound you're after just use any good quality high-gain amp profile and a guitar with humbuckers. Personally, I mainly use The Amp Factory and Michael Britt profiles, they're excellent, the tricky bit is setting it up correctly so it sounds okay. As for isolating the guitar part, try getting hold of the master tapes I'm joking of course, the best and the only software I've found that has that functionality is Riffstation (https://play.riffstation.com), I use the desktop version. Fender have just bought it so expect the price to go up! It's quite good but it's a bit limited in what it does, but I quite like it. It does come in handy and it has some good tools available, the tempo and pitch functions are great; I hope Fender can improve it.

I isolated the guitar part using Riffstation and then I tweaked it in Audacity, there's a short 20 second clip (1:34 to 1:54) in the zip. It's not that great in my opinion, Riffstation does its best but sometimes there's too much going on and you get phasing and artefacts, see what you think.

As for the profile, use a guitar with humbuckers and select the bridge pickup. You might have to tweak the sound to suit your guitar. I would recommend you read up on the KPA amp setting section, it can change the tone a lot without even touching the EQ. There are three distortions in the stomp section which can change the tone but you don't really need them. You also don't need a compression stomp as it will spoil the sound, distortion comes with its own natural compression. I only use compression on clean and crunch sounds; I use the one in the amp section as it makes a big difference and you get some great sounds from it, especially on clean sounds.

NOTE: Before I got Riffstation, I used AIMP (http://www.aimp.ru) for learning guitar parts. It free and the DSP manager has tempo, speed and pitch functions, but Riffstation does things a lot better.

Hope it helps.

Thanks for the detailed information!

I've been trying to EQ match guitar sounds with Izotope Ozone 7 (when profiling a rig). Sometimes it works very well.
I wish there was EQ matching feature in Kemper itself. Then it would possible to "render" the Kemper EQ's (studio EQ, metal EQ etc.) to a profile. Maybe it would work, I really don't know

Thanks! It would be nice to know what gear they are using.
Whispered is a really underrated band at the moment at least.
