Dear Modulator,
I could understand your criticism if the project was marked finished. However as Sauren clearly indicates it's not. At the moment it's just a show case.
As for me it's not clear what your angle is. But if you want to try and make a Midibox project based on Sauren code, then i think there are more constructive ways to go about criticizing the developer. If you want a ready made project without any need to put any effort in, please wait until this project is done.
