Korg D1600 mkii issue!

Hey,

Hope someone can help me with this:

I use a Korg D1600 mkii to record - I mix them in a DAW but track exclusively to the Korg.

I’ve seen an issue recently whereby certain tracks will not record.

I can arm the track and hear what I’m playing - until I then press the record button and then I hear nothing.

It is intermittent and initially I had workarounds, namely duplicating the entire song and the issue would briefly disappear.

I have done a bit of testing and updated the Firmware but the issue hasn’t gone away.

Just wondering if this issue is likely to be hardware or software related and whether anyone has suggested fixes or knows anyone who could take a look?

Massively appreciate any advice on this one.

All the best

Aaron
