The RK-110 was a small batch of DIY MIDI addon boards for the DR-110, produced end 2019. The kits are not available anymore, this page is for reference.
The RK-110 Adds Extensive MIDI control to the Boss DR-110. There have been other mods for Boss’ final analog drumcomputer but the concept of the RK-110 is quite unique and fits straight over the DR-110 PCB so you can almost install it in a handclap’s time.
– Auto MIDI Clock Slave
– GM MIDI Drum map triggers (easy adjustable)
– Auto switch to User Pattern on DR-110 startup
– Use MIDI Program Change to switch patterns)
– RK110 Preferences menu (Press STOP+SHIFT to enter)
NOTE: Although we tried to make the RK-110 as much as a drop-in addon; You need a soldering iron (and soldering experience) to install this mod. See the PDF manual for options and installation instructions or look at this video
(PS: Backorder means there’s +/- 4 working days delay in shipping)
