Turn one held chord into a moving pattern.
You play a single chord and let it ring. The BM-15M turns it into a rhythm: 8 resonant filters pulse in a pattern you choose. Use it on guitar, bass, vocals or synth pads.
Draw the curve with your fingers
Each filter has its own slider, from zero gain at the bottom to maximum gain at the top. Push some fully up and pull others down, and listen for the sweet spots of your sound. The FREQ switch focuses them on BASS, to help keep low end. MIDS suits guitars, vocals and pads.
Patterns that move at your speed
The PATTERN switch selects 12 sequence patterns, in 2 banks reached through BASS and MIDS. RATE sets the speed of the pattern and the envelope. ENVELOPE morphs the attack and decay, from abrupt to smooth. Switch on the LFO and the filter frequencies shift up and down as a group. MIX sets the balance of direct and effected signal.
Control it without stopping to play
Expression pedals or other voltage-based controllers plug into the RATE, MIX, ENVELOPE, LFO SWEEP and TAP STEP jacks. MIDI IN takes external MIDI controllers on a 5-pin DIN connector. Over USB C, the Guitar Tribe application controls parameters and firmware updates. Send the output in mono or stereo. The power supply is not included.
