Nice that the tempo indicator on the player works (sort of)

(the tap indicator on the rack has been the source of many disgruntled users owing to the inconsistent flashing, but thats another thread....)

BUT...

You tap the button in time with the beat and the LED flashes at that bpm but the LED flash is inverse to how it was tapped.

I would expect that if i tap to the pulse of the music the LED flashes accoredingly. However, it appears to be off on the pulse and on inbetween

count & tap

pulse 1 & 2 & 3 & 4 &

==TAP 1 - 2 - 3 - 4

==LED - & - & - & - &

IT makes logical sense to me that the LED is illuminated ON with the pulse not OFF on the pulse.

Certainly checking your BPM with the music is made easier with a flash on the beat not an eighth note later.

slateboy, this is their official website where DR WILSON's contact information makes it easy to find him personally. Midicaptain is a very interesting product. If you are willing to spend time waiting, Dr. Wilson can provide personalized firmware services based on the specific requirements of each customer service, and it is free.

In China, we communicate through WeChat. If you have any questions, you can first contact Dr. Wilson via email and then agree on a communication method for one-on-one communication. Dr. Wilson is a person who is very willing to communicate.

Thanks for that info. Still interested to hear how your experiences, as an end user, are when coupled with your kemper player.

Hey AppleTreeChen

following your interest in the system exclusive name retrieval of the Kemper player, i took an interest in the midi captain pedal, which i had not encountered previously. Seems to be a very flexible unit so i'm interested to know how you get on with the further development and customisation for the Kemper devices. Have you any special info or a video to demonstrate some of this "custom" functionality?

Quote from Ruefus

No problem.

It’s in here....

Thanks for that, Ruefus - i do recall seeing that video.

What i was checking was does this relate to the player unit, which was the subject of the OP

Hi slateboy - I use the midi option at the moment and it’s great but my midi pedal doesn’t have any kind of ‘light’ to say it’s on or off - sometimes it just stays on because I forget lol - after some form of knowing that it’s on lol

sympathise with your situation.

The limited visual indication of which FX blocks are on and the "yet to learn" coded "bank-numbers-by-colour" on the player does make it a little harder to use than the rack or stage. Though i appreciate what Kemper have done with a compact unit is awesome.

Certainly some visual indication on your midi device could prove highly useful.

Out of interest, sfa_100 what midi device are you using and how are you using it ?

Quote from Ruefus

The 7 new effects incoming will be added to the Player. Beyond that its all speculation.

Ruefus can you elaborate on that information and tell us what you know and the source of your knowledge.

Not implying that i doubt your words, i am interested to learn what you know, please. thanks

simplest way is to use one of your FX blocks as a boost.

You could also control the output volume with an expression pedal and set the working range (ie min = rhythm volume, max = solo volume) to save consuming an FX block.

You could get an additional pedal that offers a similar function (compressor/volume/boost/etc)

going a step further, and a bit more technical, you could access the rig volume via midi control, as demonstrated here:

Player extended midi control demo and how to show slot-names

Warning, nerd alert for all midi enthusiasts and system-exclusive geeks alike...
Using an external midi controller can gain extra functionality to your Player, including a level boost without consuming an FX slot.
You can even display the names of the Kemper Player on a screen or midi controller.

PS if you want the sysex code for retrieveing rig names, i posted it here:

Post

RE: Profiler MIDI documentation - information missing on string parameter addresses

ok guys, so digging out an OLD project i started years ago and gave up on, i got as far as controlling the Kemper with midi and retrieving the preset/slot names using system-exclusive. Demo here:

the bit of code for getting the names via sysex:

(Code, 22 lines)


Sorry, i'm not offering technical support. It has been so long that i done this project i'd effectively be starting from scratch to unravel this lot.
Hope the above helps and shows you what is possible.

I already understand very well! Thank you, sir

cool- i hope it didnt come over as being patronising in any way, more of a general overview for the benefits of musicians that dont carry the burden of having to know all the tec stuff.

If you know, then you know. And you know!

Out of curisosity, AppleTreeChen are you planning to build something similar?

Quote from AppleTreeChen

Very practical

How is it possible to display rig name on the MIDI controller screen?

as briefly described in the video, using midi system exclusive, you can request the value of many parameters including the name of the rig as a string.

You obviously have to then process the midi data returned (which is another system exlusive message) and convert that data in order to output to your display device.

You could do this in a simple midi editor (something like midiOx?) but the data returned would be nothing more than a chain of numbers. The rig name is a series of ascii values (characters representd by numbers) You could of course build something using PC/Mac software but i am not educated enough to cover that.

I dont really use this pedal. It was more of a nerdy project to do a few years back. I do recall it took hours and hours.

summary-

in order to do something like this you need to understand about the following-

• midi protocol
• system exclusive (send and receive)
• ascii code
• hexadecimal numbering system
• microprocessor control and display
• some programming knowledge that can interact with midi data

if any of those mean little or nothing then i'd probanly suggest not going down this rabbit hole without doing your homework.

Been watching this issue and may have found the culprit- a badly fitting 3rd-party power-connector.

admins/tec-support:

Does the internal power-supply circuit (not the external PSU) have smoothing/filtering besides the ability to handle 9-12v?

I wonder how much or a brief power fluctuation the player can deal with?

And, what are the correct dimensions for the DC connector-terminal (internal and external)

Thanks for info dfdfan and Steve5478

This led me to do some further investigation and i discovered that you can actually access those hidden parameters via NRPN midi data,

Example of accessing the amp compressor (not available using rig manager)

Amp compressor:

NRPN 1290, range= 0-16383 (NRPN MSB:10 LSB:10)

and away you go!

Definitely one for the midi-nerds.

Now, who can provide a list of all the parameters that are hidden?

Quote from ZurabMelua

The fix was to format the device using my Kemper Power Rack by inserting the stick, pressing 'USB STICK' then pressing 'FORMAT DEVICE'.

nice tip, thanks ZurabMelua

So we know there are certain compromises and omissions from the Player, making it the (great little) compact unit that it is.

With the full-blown units (stage/rack/etc) there are parameters such as "compression" in the amp section. (others too but i dont recall from memory)

What happens to these when imported to the Player?

Are they there but inaccessible (they dont appear in rig manager) or can they be accessed via NRPN midi parameters?

Or, if they are discarded as part of the import, is their value still applied but fixed at the value it would have been saved on the rack/stage units?

Curious to know as if i want more "amp compression" could i set it on my rack then export/import the updated rig back to the player or is it bypassed or lost?

is it worth starting a thread someplace with a list of "tried and tested" USB-Midi adapters?

Could be useful to share our experiences of what works and what doesnt.

i currently have RM version 3.5.20 and player OS 10.9.3.50342 but when checking RM for software updates it says OS 10.9.2 is available.

Is this an error as it appears to be offering an older RM and older Player OS ?

.

i notice similar. a power off/on does not appear to retain the last tapped-tempo (as it does on the rack)

Side note: curiously, whilst we talking about times, i notice there must be some internal clock in the player as the back-ups have a date stamp.

Anyone know how or when the Player sets its internal clock?

Anyone else found the 9v power-supply connection temperamental or unreliable?

I notice that a light knock or nudge of the plug is enough to momentarily interrupt the supply voltage which results in the Player crashing (single flashing red LED on the bank button)

Thinking ahead, if this is to be used on stages where there is some vibrations likely i am not confident with it.

What are the specs, ie dimensions (internal and external) of the 9v socket and plug.

There is clearly some "play" in the terminal and although the supplied power-supply has a better-than-average plug it is still possible to wiggle to a point of no contact. I'd expect the internal voltage regular to have some additional smoothing to deal with light supply-voltage ripples but to what tolerance, i dont know.

Maybe there's some dirt on my terminal (i will take a look)

Curious to know how far you can jiggle your plug before you get a crash.

You could have each bank of 5 as 4 slots of user-sounds and the 5th as the "kill-sound" preset.

For the "kill all" slot, put in a volume or effects loop at the end of the chain that stops all audio.

Not tried it myself but thinking out loud of the possible options...
