TB DualVCF Battery Drain? (While all other TB seem very power efficient)

Firstly I’m a huge TB fan and use their apps in everything, because of the great sound, CPU efficiency and stability, so I was quite surprised to find that DualVCF seems to be such a significant battery drain.

In about 20 mins of an AUM set with just one synth, DualVCF and TB Reverb, battery had dropped about 20%, which is highly unusual for me, and after removing DualVCF, battery drain returned to its more usual slow rate. I noticed it last night, with same setup, when after 40 mins of use from a full charge, battery dropped to just over 50%.

I’m on an iPad Pro 2017 on 13.6.1 ...

Has anyone else noticed this?

  • In AUM:
    DualVCF goes up to around 60% dsp on my iPhone6S.

    It’s the heaviest filter, but also the most analog sounding, because it has the least digital aliasing when overdriven.

  • Dev helpfully responded that recent changes by Apple to Big Sur and iOS have forced complete screen redraws (rather than screen regions) which explains the sudden increase in battery drain.

  • We'll push out an update soon with a significant reduction in CPU load and a workaround for changes (bugs?) in iOS that are quite unfortunate. We'll also improve the UI responsiveness for small form-factor devices (phones) by increasing UI elements by 200%. Stay tuned :-)

    Yay, hope the 200% for phone apps is across the board?
    And if possible allow option to use the 200% assets on iPad as well.
    (With a degrading eye sight bigger is better and more usable)

    One easy tip here is to use 'value boxes' that can be swiped up/down instead of knobs and sliders.
    Sure not as 'fancy looking' but in practical usage it's exactly the same, swipe to change a value.

    Looking forward to the update(s)

    Cheers!

    Thanks again for all your efforts!

  • Update is out. The UI improvements are fantastic as well, @djb. Much more usability now

  • Looks good on phone now split across 2 screens. 👍🏻
