The Yongmei YM-490F is a full-sized electronic keyboard made primarily as an inexpensive introductory keyboard. It is heavily based on the Miles MLS-4900A (Miles and YongMei are largely the same company). The keyboard itself has 49 keys and 5 extra keys to the right which are for a drum and a cymbal key (the two sharp keys are one cymbal, the three white keys are one drum). There are also 10 timbres and 10 melodies.
