The most common mistake is not connecting the audio outputs to a quality sound system.
Don’t laugh, statistics prove this... use standard 1/4” TS (Tip-Sleeve) signal cables connected to the Main L/R Outputs on the back panel. Please walk around the back physically check this connection or plug a pair of quality headphones into the Phones jack. Visually verify these jacks directly — many make assumptions about where the Main L/R Outputs are located and wind up connecting to the AD INPUTS.

Let us know.

I would recommend monitoring the output using headphones plugged into the correct port using the correct TRS ("stereo" ) connector instead of your studio monitors/amplifier/etc.

1) Press [CATEGORY SEARCH] button
2) Place master volume to 1/2 way mark
3) Choose "Init" category and select "Init Normal (AWM2) " Performance
4a) Looking at the home screen (with one Part) press piano keys and look for the level bar to rise and fall. If you see none of this:
4b) Check [UTILITY] "Settings" -> "MIDI I/O" menu and check if "Local Control" is turned on. If was off, repeat step 4a. (You mentioned already checking this)

Most of the above steps are to gather if you see the level bars "dancing around" as you press keys. This is to ensure the keys are triggering the tone generator or not.

Thankyou Jason and Bad Mister bit solution rechecked both solutions and it worked. Really Happy MODX owner now. 😀

Actually the init normal awm2 piano sound is excellent!! Many thanks
