I made a video of the smooth seek, so rather than playing the rendered wavs in the SavedTracks folder within the Plugin it's playing all the sections the new way directly in Reaper.
VST6-Smooth-Seek.mp4Yes, that sounds fine. I did believe you, though

Those keyboards are around $5000 compared to $569 for Biab.
I said years ago to have a hardware version of Biab with an LCD touch Screen.
Indeed. All the better arranger keyboards are that kind of price. Ketron's SD90 (module, no keyboard) is significantly less and pretty good.
I have a touch-screen on my older laptop, though it's a rather short of power for this, the screen's small and beyond the keyboard, so not really ergo-friendly. I have vArranger on it, but don't use vArranger for that reason. My large touchscreen has lost touch, so to speak, but that may be just a USB-cable problem.
