Roland TR-707

The TR-707 is a great source for cheap 909 samples. It has some other cool features too such as its Matrix display which clearly maps out your pattern for you in an easy to read display panel. It also features both MIDI in/out and DIN sync control - the best of both worlds. Why this unit even has individual outputs for each of its drum tones! For programming, it features a shuffle and flam effect and its programming abilities are very impressive. But it does have its limitations, the only adjustment you can make to each drum tone is volume.
