The RN-9090 is a hardware sequencer developed with the Arduino prototyping platform. It is a 192 button 12×16 button grid with 11 assignable rows with 16 steps each. The RN-9090 was created to supplement the TR-9090 clone of the Roland 909 Drum Synthesizer. However, it can also interface with virtual studio softwares like Ableton and any hardware device that accepts MIDI Note instructions.
The RN-9090 features a pages feature with two unique pages. Each page can be independent or the pages can be linked together for a 32 step sequence. Independent pages can be “swapped” at the press of the button. Swapping pages will make the alternate page the active page for playing music, leaving the other page free to manipulate without the pressure of correctly laying out a pattern without interrupting the sequencer steps.
There are many adjustable settings within the RN-9090. The tempo, primary velocity, and accent velocities can be adjusted by dedicated potentiometers. Within the MIDI menu of the RN-9090, each MIDI Note assignment for the primary and accent rows can be adjusted for a total of 22 unique MIDI note assignments. The MIDI channel can also be changed via on the board menus as well. Up to 11 different MIDI settings can be stored and recalled through the integrated storage on the RN-9090.
