Keystep Pro+RPB50

This bundle combines the KeyStep Pro 37-key controller with the RPB50 portable Bluetooth speaker, so you can sequence and hear your work without a full monitoring setup. The KeyStep Pro delivers four sequencer tracks at up to 64 steps each, a seven-mode arpeggiator, chord mode, and an integrated metronome. Its 37 slim keys are velocity and aftertouch sensitive, and a crisp OLED display tracks your progress across sequences and patterns.

Connectivity spans four CV/Gate/Mod outputs, eight drum gate outputs, MIDI in, two MIDI outs, USB, and clock sync for tying together analog synths, modular rigs, and DAW sessions. The RPB50 speaker pushes 20W x 2 RMS through dual 3" full-range drivers and two passive bass radiators, delivering balanced sound with noticeable low-end presence. Bluetooth 5.1 connects wirelessly with a 33-foot range, and the 7.4V/4,000mAh battery lasts up to 16 hours at low volume. Dual LED rings cycle through eight lighting modes, and the TWS function pairs two speakers for true wireless stereo. USB Type-C charging, a 3.5mm aux input, and TF card playback round out the inputs. It is a practical way to monitor your sequences in a bedroom studio or carry sound to a jam session.
