Can you use it for playing saved loop layers without it starting with a count in?

not without a switcher pedal. there are great videos on this unit on you tube. it does so much more than they say, but to change ANYTHING on the fly ya GOT to have that pedal, which they should include. i just use it for practice as every single loop on there has a crash cymbal. sounds great but...there are no straight rhythms like country or blues without fills. i thought i could down load more rhythms from the flamma site but they don't support Linux for download "it's not popular" ... so there ya's are. i have several flamma pedals I like alot, but more thought,imo, could have been put into this. good luck. God bless.

Does it operate with batteries or power supply?

Power Supply and it needs to be 9V 300mA.

Can you edit the drum beats or have more options to download from an external source?

As far as I know, you can not edit or add drum beats with this pedal. I have never used it in conjunction with a computer or other external source. There are other pedals that have that capability, but not in this price range.

Can preset slots be different lengths of time ?

Yes. Each memory can be up to 4 mins long. They can each have different length up to 4 mins.
