There's a lot in this thread, so apologies if I miss anything or repeat something others have said.

My assumption is that the problem comes down to these settings. In this image you've got the MIDI input and output set to the same device. This could cause a feedback loop, which could easily cause stutter (particularly if the keyboard has local control enabled, or if the MIDI is plugged into MIDI Thru instead of MIDI Out). Try disabling Local Control on the keyboard itself, or try selecting Microsoft GS Wavetable - and if that works better, select "No MIDI/sound output" then enable "Use VSTi/DXi Synth", click "VSTi/DXi Synth" and choose CoyoteWT from the list.
