I need only looper Quantization.

MirekGR10 · Nov 16th 2016

I have everything ,what I need.
Im waiting my new Profiler Remote.
One feature missing.
,, Quantization"

I made it with Arduino,but is not comfortable, like with PR.

Sorry my pure English.

I am afraid that you will miss it for a long time.
The Kemper helps you to have a great sound for live and recording - but the correct timing is up to you

Looper Quantization?

Robrecht · Nov 16th 2016

I read it as pitch quantization, i.e.: "snapping" each note to a preset key. Kind of like the harmonic pitch shifter does with the pitch shifted notes.

Edit: Since you mention the Remote, @paults is probably right!

MirekGR10 · Nov 16th 2016

Sorry
Of course ,,Looper quantization".

Sharry · Nov 17th 2016

Looper quantization would be a very senseful feature.

@paults has the feeling to read between the line

Yes, to me! +1

I am there to 100% with you, i hope now synonymous for more than a year on this function.The KPA Looper is ok (Sound & Looptime) for me, but without quantization for some applications unfortunately unusable. As I've heard it, but this has currently no priority,so i am currently looking for an alternative, but this also means more gear on the board. With my old Zoom G3 it was already better.

could you please share, what you did with arduino?

Quantisation has some uses and some drawbacks. While great in 4/4, suppose you are playing in an odd time signature: quantisation would really screw things up.

Because I'm not programmer, my arduino is very complicated, and confused
I rebuild it and now does not work

I know quantization from a boss looper pedal.
But this has drums in it.

How would quantization work, without included drums?

For example, i use a BeatBuddy-Drummer, the BB can be sync via MIDI with Tap-Tempo on the KPA-Remote. Now, of course, it would be nice if the Loop runs synchronous to the BB.

I made with Arduino, same philosophy like Boss Rc.

I set tempo 120 bmp. or 125 bmp etc 4/4 bars
Button start
Arduino send commands for record
Arduino counts 4 bars or 8 ... etc until I push STOP REC., If I push before the appointed time, Arduino counting ,waiting and after 4/4 or 8/4 etc sending commands for STOP REC .

Code

switch(auto_play)
  {
    case 1:

      break;
    case 2:  

    ts = millis();


      auto_play = 3;  // Move to the next state
      break;
    case 3:
      // If one second has passed, then move on to the next state.
      if(millis() > ts + (tempo-(ts-TimerB )))
      {
        auto_play = 4;

       midiOUT(0xB0,0x63,0x7D);
      midiOUT(0xB0,0x62,0x5a);
      midiOUT(0xB0,0x06,0x00);
      midiOUT(0xB0,0x26,0x01);

      }
      break;
    case 4:
      {

      midiOUT(0xB0,0x63,0x7D);
      midiOUT(0xB0,0x62,0x5D);
      midiOUT(0xB0,0x06,0x00);
      midiOUT(0xB0,0x26,0x00);
      delay(1);
      midiOUT(0xB0,0x63,0x7D);
      midiOUT(0xB0,0x62,0x5D);
      midiOUT(0xB0,0x06,0x00);
      midiOUT(0xB0,0x26,0x01);
      lcd.setCursor ( 0, 3 );                
      lcd.print("LOOPER :   PLAY >>> "); 
      digitalWrite (ledPin_1_2,LOW);
      digitalWrite (ledPin_1_3,HIGH);

      }
      auto_play = 1;
      break;

      default:
      auto_play = 1;
      break;

  }

Bus this would not help, if the profiler does not give you a "tick" on which count it is right now?
Or you would have to get this "tick" from external source, which makes it a non-Kemper solution.

... or do I still missunderstood something?

The Kemper can serve as a midi clock source, this could be used for a quantize function.

OTOH I'm not too sure how reliable a clock source it is. I've measured the regularity of the Kemper bpm, and it seems that there is a lot of jitter. Wouldn't want it as my main clock source.

MirekGR10 · Nov 20th 2016

Yes
We need external tick.
In Arduino you can use metronome.

My BB runs constantly with the beat from the Kemper, i can neither fluctuations hear nor see in the BB-bpm display.

I hooked up my Kemper to my floorboard (which has its own midi clock, though I prefer to use my Akai sequencer) and asked it to display the BPM. It was all over the place.

Perhaps it's user error.
