I've always had trouble with a custom tap tempo button not being very responsive.
Eg, I have FX4 set to "Rhythm Delay".
I add a custom button, touch mode = "Single-press", Action = Effect->Rhythm Delay->Time
The button displays OK, and flashes in sync with the delay time. However, using to tap in a delay is extremely unreliable.
However, using the tap buttons in the "Mutegroups / FX" dialog is extremely responsive.
It would be great if whatever was stopping the custom buttons from functioning well for tap tempo was fixed. Alternatively if you introduced a new button class of, say, "FX Tap", with a simple parameter of 1-4, that would work.
I have the same problem across all 3 Android devices I'm using:
Kindle Fire 10
Nexus 7 2013 running Lineagemod 14.1
Additionally, I note that the FX tap buttons aren't available below the Mutegroups in the Mutegroups dialog on Mixing Station XR, as they are on Mixing Station XM32 - it would be great if they could appear in the XR version too.
Mixer Model: X32 / XR18
