Quantized Looper?

  • The Profiler Model referred to in this thread is ...
    ☑️ Profiler Player

    I have used the looper on my stage extensively live, using logic to send the “super-midi” N _ _ _ messages (sorry cannot remember the acronym!!)

    Good, but not matter how accurately I position the record and playback triggers I was aware that it seemed to a bit hit or miss as to how well it locked in with a backing track (being played from the same DAW).

    I have now been able to get my player to sync perfectly with the DAW (logic) for the purpose of tempo delays and gated tremolo effects, does anyone know, is it possible to get the looper to quantize the record and playback triggers if the player is receiving midi tap tempo information (or midi clock or something)?

  • Well, yes, I assumed that :). But what is the midi he's referring to that relates to loop quantization?

    Some advanced loopers use midi clock and a stretching algorithm to always start on the down beat and loop correctly. RC505 is one example.

  • I don't see why it shouldn't be midi clock? To my knowledge midi clock includes a master pulse that would allow the looper to align with the closest down beat. Right?

    Generally, no. MTC is usually required for that. Midi clock is usually just used to share the tempo.

    Regardless, I'm just curious what this other midi message is.

  • That was answered a few messages above I think. And yes it's not currently using midi clock to sync the looper. Which is why OP started the thread in the first place.

  • I'm just saying AFAIK, Kemper only uses midi clock for tempo, not quantization.

    My question is: what is this super midi he's referring to? I'm curious what that is.

    I don't think the midi messages were super messages. English is my 2nd so excuse me while I try to explain what I mean lol, but...

    "using logic to send the “super-midi” N _ _ _ messages"

    You can read this as "he sent MIDI-messages that were super" hinting at some secret and magical MIDI message. Or "he sent super-MIDI messages", as in, "he sent regular messages using the super-MIDI protocol". And I think OP meant what he said in the latter way :P

  • Sorry for my absence - yes my “Super Midi” was absolutely referring to NPRN that allows detailed control of some looper functions (beyond start / stop that are available via regular midi (I think #80 / #81).

    As far as an essay… we’ll see.


    No I’m running into serious challenges getting the Kemper (Player or stage mk1) to sync in a way that reliably gets the downbeat to sync.


    For example, midi clock pretty perfectly syncs it up so that delays are perfectly timed etc - no worries there at all


    BUT, when using something like the pulse slicer, the tempo of the pulses is modified correctly by midi clock tempo information but no matter what I try (transmitting additional TAP messages (#30) I cannot get the downbeat of the pulse to line up with the downbeat of the music.


    The closest I’ve gotten is to not use midi clock at all but transmit a TAP pulse (#30) on every beat. At this point the downbeat of the pulse slicer does now always start at the same place, unfortunately it’s about half a beat off from the downbeat of the music - and I’ve tried all kinds of “delay midi signal by “x” ms from the DAW - nothing seems to work.


    On the looper, it sounds like there is just no quantizing available so c’est La vie - triggering via midi is pretty good - I’m just looking for “completely locked in”.


    To have all the tools on board but to (at the moment) be unable to implement their use in a way that really locks in with a backing track is pretty frustrating, but hopefully we can get close!!!

  • As I mentioned, AFAIK, Kemper only uses midi clock for syncing tempo. Syncing tempo is all you need to get delays to sound right, so that's why those sync properly. Tapping only sets the tempo and has nothing to do with beat sync. Basically, AFAIK, there is no concept of beat in the Kemper. That means there is no quantization.

    The closest you can get would be to mimic quantization by using your DAW to start and stop the looper on the beat.

    Selected a post as the best answer.
  • OK, I have posted about this before, and I keep thinking I’ve found a way but it turns out to not be reliable.


    I sync my Kemper player (or my Kemper stage) via midi clock from my DAW. Done, delays in time, perfect.


    My pulse slicer changes time to match whatever tempo is coming in from the clock, great BUT…


    I cannot get the pattern to sit “on the beat” so that the start of the note sits with the drums etc on a backing track.


    I have tried tapping the tap tempo button once at the start of a bar which apparently will cause the pattern to line up… it just doesn’t. I have sent taps via midi perfectly on beat 1… it doesn’t work


    I have turned off midi clock and sent taps via midi on every beat and this is the only non-random thing - it does not cause the pattern to be on the beat but it does cause it to be about half a beat off, but there no way of “moving the pattern”.


    I have even tried midi programming the volume pedal (CC#7) to have a volume square wave but unless the pulses are very slow it doesn’t respond properly to this information.

    Nothing works reliably.


    Has anybody done this - I want to get a chopped gated effect like for example the guitar on boulevard of broken dreams by Green Day. Currently I achieve this by using a Drawmer DS201 with an analog signal from the DAW as a side chain trigger (the old fashioned way). It works, and on my Kemper Stage I can run the Drawmer in an effects loop and that works quite well, but on the player there is no loop so it would have to be going through the Drawmer 100% of the time. Which seems daft, given that we have this exact effect in the Kemper now and have done for a couple of years, but it’s not useable in a live context because it can’t be reliably lined up to a beat.


    If anyone has a solution that would be awesome BUT, please feel free to comment with “have you tried… x”, but I’d much prefer to see a video of this actually working rather than thoughts about what people think might or should work.
