  The concept of a hybrid readout of a time projection chamber is presented. It
combines a GEM-based amplification and a pad-based anode plane with a pixel
chip as readout electronics. This way, a high granularity enabling to identify
electron clusters from the primary ionisation is achieved as well as
flexibility and large anode coverage. The benefits of this high granularity, in
particular for dE/dx measurements, are outlined and the current software and
hardware development status towards a proof-of-principle is given.
