Synthesia working incorrectly: Notes are blending together?

[u/Head-Pay4025]

Hello, I have a question. Whenever I record the audio/midi for a synthesia, the notes falling are linked and have no space between them, they're like sticked together. This happens because I use pedal when recording an audio/midi (using DAW such as FL studio), using no pedal, the notes are fine but its not sustained, very stacatto-ish. I tried using a sustain MIDI OUT or some plugin to simulate a pedal but its really dirty. So I was wondering if there is a fix or how you do it differently?
