Vintage BOSS DR-550 MKII Dr. Rhythm MK2 Drum Rhythm Machine Music This item is pre-owned. Please note there are signs of wear due to the age but this device still works. Output jack can be slightly scratchy though. AC adapter NOT included, but accept a BOSS standard 9V negative-tip PSU or 6 AA batteries. The DR-550 MkII is the upgraded version of the venerable, original DR-550. A big difference from the original model is the fact that the base ROM has been almost doubled and now features 91 drum sounds. The machine works at 16-bit and is fairly clean and punchy. Many of its sounds remind of its bigger sister, the Roland R-8. Useful features include "tone color", that allows you to modify the basic filter frequencies of each sample, and "decay", that obviously lengthens or shortens the sample. There are 64 preset patterns on board, and 64 more slots for your own creations. Also, as in other drum machines in the DR-series, you can chain patterns to forms songs - In the DR-550 MkII, up to 8 songs consisting of up to 160 measures each. This is a digital 16 bit drum machine that has 4 different drum kits, 91 drum sounds, and is MIDI compatible. Dimensions are approximately: 7.5” wide x 6” tall x 1” thick.
