House

A house is a pattern used for habitation by people that generally has walls and a roof to shelter its enclosed space from precipitation, wind, heat, cold, and other elements. Animals including both domestic pets and unwanted animals often live in houses. The word house may also refer to a construction that shelters animals, especially within a zoo. The social unit that dwells in a house is known as a household. Most commonly, a household is a family unit of some kind, though households can be other social groups, such as single persons, or groups of unconnected individuals. Settled agrarian and industrial societies are composed of household units living permanently in housing of various types, according to a selection of forms of Land tenure. English-speaking people generally call any building they routinely occupy home. Many people leave their house during the day for work and activity but typically return to it to sleep or for other activities.

SYNC

The SYNC standard, repeatedly called DIN sync, defines an interface for electronic music instrument. It was introduced in the 1980s by Roland firm for synchronization of music sequencers, drum machines, arpeggiators and similar devices. The SYNC standard uses the signal device and start/stop. This means the low position is 0 V, the high position is about +5 V. The clock signal defines the speed of the progression or drum pattern.

The start/stop signal defines if the sequence is successively ie;start/stop = 0 V -> stop, start/stop = +5 V -> running.The SYNC standard uses 5 pin DIN connectors, the same as used for MIDI, but uses a special pin-out. The term DIN sync does not mean that it is a DIN normal, only that it uses DIN connectors. In some applications the outstanding pins (4 and 5) are even used as tap, fill in or reset and start. But this differs from machine to device.To connect two SYNC devices a cable with a 3 or 5 pin plug up on each side has to be used. A standard MIDI cable is not fitting as here the pins 1 and 3 may be unconnected.
