Roland CR-78 | Vintage Synth Explorer
The CR-78 is a really great little box from Roland. It's a classic analog Rhythm Machine, not a drum machine, and was the first to use a microprocessor. It has 34 built in preset rhythm patterns which can be varied at the push of a button. These patterns include Rock, Disco, Waltz, Shuffle, Slow Rock, Swing, Fox Trot, Tango, etc... Some are cool, but the ability to vary them gives you some creative control.
Oberheim OB-1 | Vintage Synth Explorer
The OB-1 is a simple and great monophonic synth from Oberheim based on the same synth architecture as the SEM. Released in 1978, it was the first truly programmable analog synth of it's time with 8 program memories.
