I play synths, and I'll be renting out a ModX 7, I have once used it, but I didn't have time to figure out some stuff like Yamaha's Steinberg USB Device, USB Volume, etc., so for people out there who has ModX 7's or similar, what is the latency in milliseconds (64 samples) of the ModX when connected to a computer via USB using the Yamaha Steinberg USB Control Panel?
Input Latency: 3.447 msec, Output Latency: 4.444 msec on Windows 10 using Standard Mode
Latency is going to be somewhat a function of the host PC's CPU and/or internal bus architecture and then the buffer size chosen has a big impact on latency. So YMMV vs. any individual readout of latency given by the software readout.
The comment here is that the latency has dependencies outside of MODX itself and therefore can't be answered with a single number. Folks can generally, with relatively modern host hardware, dial in a latency that's below the "magic number" where latency becomes a distraction.
