Jordan Suckley made nice tutorial.

Thanks but I don't think this is it mate. I tried this method already with the 1 bar midi and changing up the 2nd or last bar it's just not right.

It's either changing the 16th note midi order or it's gotta be the arp where the individual notes are shifted up or down a few similar to acids but I don't even know where to begin with trying to get the pattern.

Can someone please help me out...

I didn't mean it like that mate.

In fact I greatly appreciate all the quick responses.

I know how to make the 16th notes rolling trance bass line. I am trying to get a similar "roll" to Atkinson's.

Which notes would I be moving up or down? I know the typical patterns like

K C1C2C1 K C2C1C2 K C1C2C1 K C2C1C2

K C1C1C1 K C1C1C1 K C1C1C1 K C1C1C1

K C1C2C2 K C1C2C2 K C1C2C2 K C1C2C2

But I don't know how to make it roll or go up/down like the Atkinson one.

I'm so frustrated right now I have been trying to figure for months.

Looking to make more than just a generic rolling trance bass line and I was wondering how the bass lines in these tracks are made

As you can hear it's more than just a basic rolling 16 note trance bass. The notes in the first one make it seem like its rising or going down all the way until the end of each bar, and the second track's bassline sounds like it's going up and down near the end of each bar. I hope I am explaining that right.

It could be as simple as just moving a few 16th notes up and down, or using an arppegiator, but I am not entirely sure.

I don't how to get the arppegiator pattern to groove like that.

Can someone please help I have been trying to make similar type of bassline for a while now. I want to make something different than just a generic uplifting trance rolling bassline.

I do not have Omnisphere, nor am I familiar with Massive. I am looking to make this in Sylenth/Spire/Serum... I am trying to get it as close as possible or at least sound decent. I have Cthulu and can use it for the arp but I have NO idea how to program it like the track in my post.

Any tips to point me in the right direction is much appreciated.
