This large, flat drum machine was designed to fit atop an organ. This black tolex version was designed to go on the road. It has a handle on the left side and feet on the right side and bottom. So, it can be used flat or sideways. It has 32 patterns and lots of adjustables like separate volumes for bass drum, snare, guiro and maracas-cymbal-highhat and fade out. If the tempo isn't fast enough, there an \"up tempo\" switch to double it. You can press several buttons at once to get strange patterns. Another unique feature is the metal touch plate for start and stop. This drum machine has better bass drum than the CR-78. Has 13 sounds (bass drum, low conga, low bongo, high bongo, snare drum, rim shot, clave, cowbell, maracas, hi-hat, tambourine, cymbal, guiro). Grossly undervalued.
