I want to know the answer to the following question:
what are the Roland TR-808, TR-909, and TB 303 examples of?
All the background I'm provided with is that "Larry Heard, a.k.a. "Mr. Fingers", claims that the term "house" became popular due to many of the early DJs creating music in their own homes using synthesizers and drum machines such as the Roland TR-808, TR-909, and the TB 303.[citation needed]". Is that enough to answer the question?
Answer: yes
