Your Roland microcube AC is waste up

I believe that tempo would be the same as the metronome

Your best bet would be to contact Roland Support. The link is-

The P90 uses a rubber membrane switch to turn the metronome on/off it maybe that this has failed. Inside the rubber is a carbon contact that bridges over the PCB. If this gets dusty or worn out then it will not operate. This could be the cause, dismantle and clean and try again.

If not then it is with the electrical circuitry which would be harder to diagnose.

Hi, after doing a bit of googling it occurs to me that the internal speaker is ONLY for the metronome / click & not for the drum sounds themselves. You will need headphones or some external audio gear like your hi-fi system or oth r amp & speaker. I found this "The pad has 54 sounds in it (covering all parts of the drum kit but mostly snares), which are triggered when you hit the mesh head, but these can only be heard over headphones. The built in speaker is only used by the metronome sound (when there are no headphones attached) and then it only has a beep sound attached to it. However, plug in headphones and you get a variety of available click sounds including a proper ticking clockwork metronome." Hope that helps a little? Good Luck :-)

Most of the problems with these type units are due to dead batteries or incorrect power adapters and broken power jacks, Check for those things use ONLY the original type power adapter.

The metronome speed is controlled by the Tempo setting. The metronome controls only adjust the volume of the metronome and if the metronome is heard on the input or output recording. The R24 manual is available here: http://www.zoom.co.jp/downloads/r24/manual/ . See page 20 for setting the Tempo. The Tempo button is below the Tempo label to the left of the LCD display on the right side of the Zoom R24.

I hope this helps.

If you have the beat generated, and merely want to save it, press Write Button once. Use the tempo up and down arrows to select the memory location and press the Write button again. it should store it.

If you are just looking for a different random shuffle, the metronome is hard coded and limited to what you can change on it.

If you did not get the owners manual, it is here:

Take it to a place that repairs clocks. They should be able to help you.

Turn on metronome. Make sure that metronome is not operating. If it is operating then press metronome switch to stop it. Now press up (^) or down switch. This will change the time signature. When u get appropriate time signature, press Metronome switch once. It will start operating with selected time signature...
