A musical instrument stand with a self-locking neck lock assembly for a guitar-shaped musical instrument has a post, multiple legs and a self-locking neck lock assembly. Consequently, the trap modules can be made in large production quantities at minimal cost. The drive member includes first and second segments wherein the first segment has a profile sufficiently low such that, when the first segment cycles through the upper cycle portion, it does not extend above a plane defined by the tops of the first and second rollers. As a result, an optimal set of suggestions and recommendations can be provided for a given engineering or business issue or problem. The reception and processing of the P-BCH may be initiated immediately after receiving the handover command or after sending the handover complete message.
