Subject: [korgpolyex] EX800 scrambled patches
Hi everybody,
My EX800 has been experiencing problems. Basically, from when I bought mine, it used to lose its patches occasionally: all patches would change into this nonsensical white-noise-with-square-wave-and-lfo jumble. Also, the midi channel was set to a nonsensical channel (f.i. H87). I managed by sending a sysex patch, which always fixed it. Now it seems to be getting worse: everytime I turn the EX800 off, it loses its patches.
Anyone had this or a similar experience?
Best regards and thanks for your input here!
Pieter
