no, i need a description for the “control surface”  (http://www.ucapps.de/midibox_sid_cs.html)? What are the things a need for?

Just follow the link DRÄPPEL alredy gave you.

And you willfind this (Step A IS the CS!!!):

Control Unit (Step A)

Additional parts and modules:

a 2x20 LCD (or larger)

a MBHP_DINX1 module - premade PCBs are not available for this small circuit, so you have to build it on a vectorboard. Alternatively you could use a DINX4 module.

a rotary encoder (datawheel, endless pot)

A detented encoder is recommented for precise data entry

an improved PSU (ca. 500 mA)

6 buttons (or more if larger LCD is used)

Costs: ca. 20-25 EUR for a backlit 2x20 LCD, 1..2 EUR for the rotary encoder, 1..6 EUR for all buttons (depends on the quality)
