Abstract
The invention relates to an arrangement, with which pressure point characteristics can be simulated, such that a key stroke typical of a cembalo, as well as the key characteristics of an organ can be as near as possible approached and permits the replication of a dynamic key stroke, as well as multiple pressure points during a single key operation. At least one sensor (3) is rigidly arranged for each key (1), from which positional data, about the key, is sent to an analog signal preparation unit and a programmable analytical unit (6), which generates data for an externally connected digital signal processor (7). Each key is coupled to an electromagnet (2), which is controlled by the analytical unit, depending upon the positional data and a current program. The arrangement for the creation of pressure points in keyboards is suitable for piano-like electronic keyboard instruments, electronic cembalos and electronic organs.
