At our live gigs we always record 18 inputs to the sdcard.
During our live show I want to make some adjustments e.g. of the monitor levels at the M20d operator touch panel (not the ipad)
Here I notice a slow performance. That means the touch panel of the M20d reacts very slowly and also the vu-meters are not in time and are stuttering.
For comparison I took the ipad. There is no performance problem at all.
I reflashed the 1.2 firmware. The same result !!!
I made also tests at home with a virtual soundcheck (sd card). the same.
I tried to reduce fx. the same.
the sd card recording or playback is the reason for this problem.
But why does the ipad app does not have this problem ?
I noticed only one difference between M20d and the ipad. The M20d makes FTA in the EQ section.
This is not done by the ipad app. Could this be the reason for the performance problem ?
I'm very stressed about the problem, because in a live situation the sound system must work without a problem.
For me it is a "NO GO"
If I can get no solution for this problem, I tend to switch to another mixer.
Mybe some of the admins can deal with problem and can confirm it.
