Thank you Bad Mister. I asked this because I experienced delay while playing with a piano smple in sforzando(it plays sfz files) and it's a cool software which helps me to learn more about sound synthesis concepts 😀 Somewhere I read that it can be because of the sound interface driver. I don't think my laptop has a slow cpu or not enough ram (8GB should be adequate?) also I never had any issues with my keyboard in othe software.
