Brilliant idea!!
I'm always jamming and noodling but always forget to hit record and when I do I often seem to lose the flow* so this just for me
Will be getting my 10 Aussie dollars when I get home (not sure what that is in pounds)
*I think the reason is I need my unconscious mind in gear to connect to my creative energies but when I have to remember to turn on record it engages my conscious mind and blocks my flow process - pita
