This is a special metronome that great German composer Karlheinz Stockhausen has waited for 50 years!!
This can play chromatic tempo scale like 63.5. You can program the tempo modulation and number of beats easily, then metronome plays the tempo as you programmed.
Ritardando and accelerando are also programable. So this metronome is very useful to learn and play his grate work.
