I recently bought a non working Poly 800 MK1. The previous owner said it made strange noises. I thought I could load the factory patches (like I have before) and bring it back to life. No joy. I tried that several times to no avail.
So far I have replaced the batteries and loaded the factory (WAV) patches and it still does the following:
Some patches make a low volume sound/noise - others do not. The filter and other parameters available on the grid seem to affect a change in the sound but it is hard to say if they are working correctly.
Any ideas?
Thank You
