tiny cherries, edible, processing?

so I thought I had an edible cherry tree

but its covered with tiny cherries about half the diameter of the cherries I am used to buying from roadside stands, the ripe ones are realy dark red I tried one and it was delicious flavor was close to the sweet blacks that are so common but intense.

1) any reason that I should suspect them to be not food ( i ate a handfull and feel fine 3 hour later)
2) any tips on pitting little tiny cherries if they are good?

As I understand it, the only cherries that aren't edible are bitter cherries, which taste nasty anyway and apparently are more of a west coast shrub than an actual tree.
You could look for a pitter of the sort they use on sour/tart cherries. I would think they are about the same size.

<laugh> I'm tempted to ask you to send me some of the pits to start my own tree with. (Just tempted, mind.)

We have a cherry tree that has fruited for the first time this year, with tiny cherries. We think it's what the locals call a ginjeira - they add them and sugar to the local firewater to make ginja, a type of cherry brandy.
