Can you imagine how fascinating it would be to make music with everyday objects? With the BMV56T123, a versatile touch MIDI controller, that imagination becomes a reality.
The product includes 16 touch interfaces, allowing users to connect any conductive object, such as fruits, plants, spoons, and more, turning anything into a musical instrument via MIDI.
Operating current: 76mA @all LEDs light up, playing a 1kHz sound at volume level 6.
Operation mode: stand-alone, networking
Includes 16 touch interfaces
Audio sources - Integrates 13 MIDI groups
⬥ Grand Piano, Rhodes Piano, Music Box, Tubular Bells, Hammond Organ, Percussive Organ
Clean Electric Guitar, Synth Bass1, Pizzicato Strings, Timpani, Woodblock, Gunshot, Percussion
- Audio sources can be added via the on-board USB interface
⬥ Supports mono .wav files
Flash memory: 128Mbit
Speaker: 8Ω/2W
Interface: UART (baud rate: 115200bps)
DESCRIPTION
The product integrates 13 MIDI groups and allows you to add your own audio sources via the USB interface. It's easy to use, simply select a MIDI, connect the 16 touch interfaces to objects using crocodile clips, and you can start creating music.
Except for the 13th MIDI (Percussion), the 16 touch interfaces correspond to different pitches. When a touch is detected, the corresponding LED lights up. Additionally, the product includes buttons for adjusting volume (level 0 to level 15), audio sources, and MIDI groups, making operation easier.
HARDWARE OVERVIEW
When using the product with the BMduino UNO BM53A367A, you only need to power the BM53A367A.
For stand-alone mode, it is recommended to provide 5V power through USB.
