Hi there,
Got my hands on Drezno but as far as I can tell I'm either missing something or it's defective. I've fed several different Eurorack level signals to the ADC input (Plaits, Sample Drum, Subharmonicon), and the bit LEDs and the faders will all light up when adjusted. I believe that means they should be loud enough to clip. I've turned the link On, turned up the gain and offset of the DAC in several configurations, but the DAC output will only give me a very quiet version of the input signal at best, giving only noise if I turn the gain up enough past a point.
By default with nothing else patched but the audio in and out, I believe it should just do 8-bit resampling, creating a subtle audio effect as stated in the manual. I don't expect it to attenuate the input by a ton. Any ideas?
