    Hi, guys. Did a search, found nothing on the issue I'm having...

    I have button 0 as a dedicated tap tempo on my AA12, and have the delay in a particular patch set to dotted 8ths, and the delay time roughly to the tempo that we play it live. The thinking was, "Get it close, and make up any tempo discrepancies with the tap tempo button." -- good in theory, but I can't get it to work properly. As soon as I try the "tap" button, it goes haywire and I can't even get it close to what it needs to do, almost like it removes the dotted 8ths setting from the equation. Any idea what the problem could be?

    By the way, the song in question is Bowie's "Let's Dance", so I need to get those rhythm guitar echoes synced!

    On the GLOBAL page of the editor make sure Tap Tempo is set to PRESET.

    Also, shouldn't the tap button LED match the current delay tempo?

    I recall theres a setting in the delay block (per preset, not global) where you can recall a preset with the delay at a fixed tempo that “overrides” the “global” tap-tempo. Other presets will continue to adhere to the “tapped” tempo which may be at a different bpm.
    I use it myself in a couple of songs when i want the exact tempo bpm for delay as i dont have opportunity to “tap” it in.
    Other thing to check is that you havent got one of the other repeats at an unusual fraction, ie the main delay may be quarter-notes but another “voice” may be echoing in dotted-8ths or something peculiar

    I am running a mono signal at the moment. The delay is set to parallel, with only tempo 1 having a value (dotted 8th's), the other 3 are set to off.

    Can you share a screen shot of your delay block? (May have to do it in two steps as it takes a scroll down to capture everything, as you know)

    I have an expression pedal set to control delay volume for this patch, FYI. Don't know if that matters or not.

    Interesting. I suspect we're missing something simple....

    Rather than assume what might be obvious, have you tried “quarter” for the delay interval, which would give quaver intervals to your bpm?
    “lets dance” by bowie? (Thats a song where i too use a “preset tempo”, coincidentally!)

    Also, have you a midi device that might be sending midi-clock or tempo data to your AA?

    Yep, Bowie indeed. I have my android tablet sending midi program change data only, so when I change to a song's sheet music, it'll change patches on the AA12.

    Incidentally, on my amp pedalboard setup, I have a Boss delay with a tap tempo on it -- set to dotted 8ths -- so that you can merely tap in time with the band and get the right delay interval. That's my goal here. Setting to a quarter was just not the right delay setting at all. I can't seem to get remotely close to what I'm trying to achieve. Futzing with the BPM parameter helped, but got destroyed as soon as I hit the tap button, and was only fixed when I changed patches and came back. It renders the tap button useless.

    Thinking about it, i seem to recall relying on the “time” value for my bpm (worked out with a bit of maths) rather than the bpm parameter in the delay block. Try working out the value and setting it otherwise to see if this offers a solution.

    The formula for mS can be obtained here
    https://tuneform.com/tools/time-tempo-bpm-to-milliseconds-ms
    Quavers @ 114bpm = 526mS, as seen in my “fixed” setting, above
    Obviously, yours will be different.

    But shouldn't the tap function override any BPM settings in the patch? That's the whole point of having it.

    A preset with a "fixed" tempo will be that until you start tapping to override that value. Ignore the led flashing.
    One anomaly that can be deceptive is that the "global" tempo (that last tapped in) is shown by the flashing led of the same BPM.
    Selecting a (new) preset with the different/fixed tempo, the led still flashes at the global rate NOT the preset's fixed tempo.

    If you create a new preset which is purely tapped (no preset BPM) and set it to your dotted-eights does it sound correct?

    And, rather than assume or imply you haven't thought of it, how are you tapping- are you tapping in quarters/crotchets or something else (maybe tapping in at the rate you wish the delay repeats to appear as?

    Tap tempo goes wrong in every preset that I've tried it in despite the respective patch settings. In this instance, however, I'm tapping quarter notes. It's never been a critical issue until now, as I wasn't using it for any tempo-based-delay songs. I need to figure this out, though, since I have more of the same type in the near future.

    I can't thank you enough for doing a deep dive into it with me!

    Sorry i couldnt help you further.
    Perhaps a video demo of the issue would be a useful guide for the rest of us to understand the quirk?
    Might be a fault that is unique to you or maybe common to the OS in which case it would be handy for all users to know of it in order to avoid the issue. I appreciate its a bit of time and effort to video the problem so whatever you decide is cool but guess it would also guide the support engineers in the right direction.

    I replied to your support ticket.
    I'm waiting on you to reply so we can arrange a phone conversation.
    If you're using Mac OS Big Sur, it could be a symptom of issues our editor is having with that OS.
    We are working on a fix for that.
    If not, you might try just updating the firmware. This will just reload your current firmware.
    Sometimes strange things like this go away after an update.
    DO NOT try to update if you ARE using Mac OS Big Sur!!
    If it's still an issue, make a backup file of all your settings, then
    download the SYSTEM RESORE file from the website:
    https://atomicamps.com/atomic-amps-support/
    Restore you unit with that file and then restore again with your personal backup.
    This too can sometimes clear up issues like this.
    I look forward to talking with you.
    Jace
