As suggested by @davide I used one of those new riffs made by guitarists for guitarists with my loyal Strum GS-2
Here is the Scaler xml Riffas.xml (9.6 KB)
I then dragged & dropped the series of chords in Ezkeys as explained here, alternative work-flow, bottom of the page
Broomstick Bass followed the guitar without even asking for a beer
And the drummer was thrifty as well
here is the result a wonderful funky vibe!
If only Scaler developers were able to make one zillion of those riffs, or to let us able to modify/create riffs…
