This comment applies particularly to acoustic-only instruments. The player has to be their own judge of whether they got it right. The notes just keep coming, which is actually what...

It would be important to make this feature optional, because looking ahead (instead of back at what you already played) is one of the things being learned.

> well it is no different to looking at a sheet of music Absolutely, and that's of course the "real life" situation. Having the notes disappear is a training situation,...

Greater range would be useful to me, also. Violin music is written on treble clef. Its lowest note is G4, which is just outside the range made available. And of...

If we implement deletes via API, we could add a dry-run parameter to the request. Also, the response (dry-run and for-real) could provide statistics on what it would/did touch. Does...

Given the following data, what is eligible for deletion, and what is the cascade behavior? ``` 127.0.0.1:6379[5]> zrangebylex cassabon_dev - + 1) "0001:foo:false" 2) "0002:foo.bar:false" 3) "0003:foo.bar.baz:false" 4) "0004:foo.bar.baz.average:true" 5)...

Do we need wildcards at all? For example, given the earlier example paths, is there (or should there be) any difference between the following? ``` DELETE foo.bar.baz.* DELETE foo.bar.baz ```...

Cassandra is lame, there are no range deletes. Suggestion: do a query, and then delete every row returned. Not gonna happen. This means that we offer deleting EVERY ROW for...

Metrics deletion is mostly in place, pending Cassandra ability to delete by range. For Index deletions: Enumerate all paths that match the wildcard. For each path: - delete all metrics...

That's a valid point. A command-line argument to control what it does, and all other functionality is bypassed. Might also be an idea for the new bootstrap functionality.
