Can someone explain what the phase locking is and why it's a problem in actual practical use (ie. in a patch that isn't just raw oscs on an oscilloscope)?

Basically, your description is telling me that this thing has a high no= ise floor, and the various distortion/gain stages conspire to make that wor= se. Apparently, nothing can be done about this ever-present noise, even wit= h the gain settings toned down. > > > > Sounds like a description of a vintage synth - especially one with chor= us (although this one doesn=E2=80=99t). > > > > Brian > > > > > >> On Oct 14, 2018, at 8:44 AM, Scott Fox <xxxxxxxxx@xxxxl.com> wrote: > >> =E2=80=A2The architecture and number of gain stages and distortions gi= ve the machine a fairly high signal to noise ratio. Even with all filters c= losed, oscillator levels at 0, filter outputs down and so on, my machine gi= ves off a wee bit of noise. Depending on what you're doing, this can get pr= etty noticable in the synth. I've experience this across multiple units and= what I wrote on this point was pretty much Arturia's summation of its nois= e in my messages with them. Basically, it's a part of the machine. Take it = how you will. It hasn't been much of a problem for me but it does but some = people whom favor a pristine sound. > > >
