Letting people create their own algs for the H9 is a tough one. Obviously we'd like to do it, but the restrictions necessary to fit complex algs into a fixed stomp box format means that it is considerably more difficult than programming our rack boxes. And, many of our users find those too difficult.
Beyond this, many algs need a UI written for the various iOS apps. Not a simple thing either. There are reasons why these algs cost $20 rather than $2. Did I mention they also have to sound good ?
So, something we'd like to do, but may take a while.
