Cubasis Audio mute and solo issue

Cubasis
1

Hello to you all.ive recently started using one shot drum samples in my project instead of creating drum kits with samplers.
When creating a project, Ive noticed that Cubasis plays sound even when I mute the tracks or solo one of them.dont know how to properly explain so please watch the video for better understanding.its like audio glitches and don’t happen immediately but after some few nano seconds after taping in mute or solo.
Here is the video

Ps there are no AudioUnits involved
Just Cubasis internal effects
iPad Pro 10.5

Hi John,

Yes, it’s clear to hear in your Video and that shouldn’t be.

Please try to put out the effects on the tracks that let the signal through in mute state.

Which effects did you load?
What are your Audio + Project Settings?
iOS Version ?

Can you possibly send us your Project without Melody ?

Your audio files are extremely short.

A freeze of the tracks where the signal gets through in spite of mute could help.

thanks for the info

Hi there Hiltmann
Thanks for the reply.i can confirm that freezing the tracks to new Audio Tracks solves the issue.
I just sent you a message with the project zip with the frozen tracks and the short samples.

Hi John1289,

Thanks for the Project and I get different results with different iPADS !

I can reproduce your audio glitches to a limited extent and i tested it on:

  • iPad Pro 1 Gen 12.9 Inch, iOS 12.2 (reproducible after mute track, audio glitch audible for 1-2 beats)

  • iPad Air 2 10.5, iOS 12.2 ( One short audio glitch after mute track, scarcely audible)

  • iPad Pro 11 2cnd Gen 2018, iOS 12.2 ( One short audio glitch after mute track, scarcely audible)

  • iPad Air 1 , iOS 10.3.3 ( One short audio glitch after mute track, scarcely audible)

  • Hardware Latency = Ultra Low, Low + Medium/ 44+ 48khz

  • Large Recording Buffer ON + Off

What I do in my first testcase :

  • launch your project
  • set track 1,3,5,7,9 in solo mode
  • start the playback
    Result : no audio glitches as clearly audible in your Video

What I do in my second testcase :

  • launch your Project
  • create new audio track A and import audio file to track A
  • mute all all tracks except track A and start playback
    Result : only when muting tracks there are audio glitches for a short time. (most clearly audible with the iPad Pro 1 Gen, 12.9 Inch, iOS 12.2)
  • Run the playback 10 times in cycle with track A in solo state
    Result : no audio glitches during playback with track A in solo that contains an audio file

You still have the spin fx running in the master channel.
Check how it runs when you turn it off.
And then please turn the iPAD off and on again and start only cubasis as app.
Maybe you still had iAA or AU apps running in the background that consume CPU resource and therefore cause your glitches.
