How do you create your Basslines sounds perfect?

like it sounds perfectly fit with your chords or melodies, I'm always going with the root note lower an octave with my bass synth but it sounds so dull, only doing that makes me and the listener easily get bore. please give me some links or videos that might be helpful for me (y)

You don't mention the style of music you're interested in, and that will of course make a big difference to your question.

In general, it sounds like you're asking for some basic knowledge of Harmony and Voice Leading (also called Part Writing).

It is never a good idea to rely solely on the Internet as your primary means of acquiring wisdom. Experience and practice are normally better, coupled with reputable books and ideally a teacher.

If you do a simple search, you will find a wealth of material available on the above topics. However, creating a "perfect" bass (or anything else for that matter), is going to take a lot of work - you're not going to get there simply by watching a few online videos. Professional musicians spend years mastering this stuff.

Start with a sine wave and pitch it down. Starting playing with FX and your sampler options, and read up on how to use these to your advantage

Much of it relies in the sound design, and the atmosphere/genre of the song you're trying to use it in. Sometimes simpler bass lines are better.
