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.\u003c\/p\u003e\n\u003cp\u003eUseful 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.\u003c\/p\u003e\n\u003cp\u003eThere 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.\u003c\/p\u003e\n\u003cp\u003eA big improvement from the previous 220-series is the inclusion of a basic MIDI IN port, which allows the unit to be synchronized to a sequencer, or another drum machine. There's no MIDI OUT though, so in order to save your created patterns, you have to resort to the old-fashioned way of storing to cassette tape, using the tape interface.\u003c\/p\u003e","brand":"Boss","offers":[{"title":"Default Title","offer_id":52026577289501,"sku":"U285047","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0266\/7708\/4238\/files\/U285047-3.jpg?v=1784065721","url":"https:\/\/www.pixelproaudio.com\/products\/boss-dr-rhythm-dr-550-mkii-drum-machine","provider":"Pixel Pro Audio","version":"1.0","type":"link"}
