This 3-chip EPROM set loads your Alesis HR-16 or HR-16B with classic sounds from three legendary early-80s drum machines:
- Boss DR-55 — One of the first compact programmable drum machines (1980), with a distinctly mechanical, punchy sound
- Roland CR-78 — The world's first microprocessor-controlled rhythm machine
- E-mu Drumulator — One of the earliest affordable digital drum machines (1982), used by Depeche Mode, New Order, and countless new wave artists
What's Included:
- 3x custom-programmed EPROM chips (drop-in replacement for stock HR-16 / HR-16B sound ROMs)
- Sounds from Boss DR-55 + Roland CR-78 + E-mu Drumulator
- Bonus: upgrades your HR-16 OS to v2.0
- No soldering required — chip swap only
Compatible with: Alesis HR-16 and HR-16B
Note: For HR-16B, chip orientation is reversed — EPROM 16 installs into socket U15. Browse my other listings for more HR-16 EPROM sound sets and Alesis parts, or DM me for anything you don't see listed.
