Filters is dead

My filter module appears dead suddenly. There’s a very faint signal going through but that’s it. Can it be fixed?

Does it have any obvious damage that could be the cause? I flattened a micro-sequencer and it stopped working - but you could see the broken wires. A bit of solder and superglue fixed it right up.

If it just stopped working due to an electrical issue, send an email to support (at) They will take care of you.

Are you powering your filters with a battery or a USB cable?
Did you check if it works with a small circuit?

A few months ago I had a situation where my filters worked fine when connected to USB power, but when using batteries the signal would be very faint - presumably from being almost depleted.

It happens powering from battery and from an ac/dc adapter with whatever circuit, long or short.
