That is very unlikely. The hardware might do 10 or 11 Bits, but not more. The protocol of course provides 14 Bits, but some of those bits might be dummy.

We would have hoped for 9 or 10 bits resolution -> 1/4 % or 1/10 % of the full fader path. (I once tested that the XTouch Compact in Mackie mode only provides 7 but resolution).

But even if values with higher resolution are sent, this does not verify the fader resolution. The firmware might calculate a timed ramp between the values it gets from the fader hardware. To test this, it would be necessary to try some really tiny moves of a fader (less than 1% of the full path) and see if the final values sent always differ by appropriately small amounts.

But anyway: if it indeed is more than 7 Bits the firmware of the "Compact" - which very likely uses the same hardware - is decently flawed. Does anybody konow if there is a more appropriate firmware for the Compact out right now ?


@HIO:

To see how many relevant bits are coming though we just need a screenshot (or ASCII cut and paste) of some 20 the HEX lines resulting from some tiny steps. A video is not necessary.

ASCII would be best to allow for doing calculations with the values in a spreadsheet.



Thanks, anyway,
