I will try to put something up but have never done any demo. Don't want to repeat what annoys me in other demos and would like to make it clean and the way I like i.e. loop the groove and tinker with settings, record clean line and not through friggin phone mic etc
This is why I got to wait for the opportunity (next visit in friend's studio)
A C Maj scale and some knob twisting will be more than enough for me
