Nice.

I wonder what this M10 tssop14 thing is?

Overall the thing looks pretty tough: bunch of ota stages controlled by lfo via current mirrors, some hex inverters and other stuff, including interlayer transitions probably hidden by smt and other components...

I saw that and just went okay, this is either a dsp, micro controller? or some kind of analog freq translator chip?

But I haven't googled anything yet.

Guy told me that it's probably another buffer array or hex inverter or even a timer, but unbranded, cheap chineese one.

But i still think that this (along with M7 chip on the other side of theboard) may be some sort of custom/proprietary logic.
