See title. Fast pieces, 1/16 th notes, have too much latency time to sound. Can this be overcome somehow? Except for optimization of the computer itself.

You don't say anything about your computer setup, but there are some settings in GO that affect latency.

In the Midi/Audio settings reduce the samples per buffer setting to the lowest number possible without compromising the sound. Too low a setting will cause "xruns" which cause the sound to break up. You will know it when you hear it.
In the Audio Output tab, select your audio device and change the desired latency value to a lower number.

Thanks, I'll look at it.
Computer set-up: Dell Vostro 430a, internal sound card, 16 Gb RAM, 120 Gb SSD, Wuderland Midi-USB cable, Content D1400 (organ).

Thomas! Result!
I could change the sample amount per buffer change into 450, 400: break in the sound, 450: not.
Audio output: to 10 ms, = acceptable, with the first within it. I will study furthermore and see if improvements will be necessary., Very simple tools ...

Good work. The documentation provides pretty good information on the settings, but you have to tweak the settings to match your processor, RAM, etc.

jitske If you use windows with the built-in sound, then you can make some expirements with the Asio4All driver. It would allow you to reduce samples per buffer a little bit more.

In my experience, less expensive MIDI-USB adapters tend to introduce a great deal of latency. Once you've ruled out everything else, you might want to consider upgrading that.

Very good point!!

I have noticed something similar with adapters between CAT and USB in
Ham Radio gear. I once spent days trying to trouble shot, without
success. Then I took someone's advice and bought a higher quality
adapter. The bad ones had chips made by Prolific. This is well known in
the Ham Radio set.

Thanks for the suggestion to use an upgrade of USB-Midi adapter. I am not busy with it at the moment though ...
