What's the expected volume of Prophet 10 with the default preset?


I was told in another forum that my Prophet 10's output level is strangely low. With the default preset (Hold record, hit preset), it's around -36dB with one voice. I've tested it with 3 different sound cards, with prophet's out going straight to a line input without any changes. Here is one example:

P10 owners: What's the output level of P10 per voice on your unit?
Thank you in advance!
