We, from Terra Eletrônica, have developed and implemented a WIRELESS MIDI network, with MULTI-TRANSMITTERS (TX), coupled to some MIDI instruments specially developed and dedicated to users with disabilities, connected in a network to a wireless USB HUB (RX) forming a network affordable multi-instrument system that runs on DAWS and commercial APPS, both on computers and mobile phones.
The “NET-MIDI-TA” system was designed to be a wireless communication platform between musical instruments specially designed to be accessible by people with disabilities. This HDW platform, with wireless communication, allows instruments of the most diverse types to be developed and adapted to meet the diverse deficiencies of this target audience. The hardware elements that make up the network are: A Wireless MIDI receiver HUB for USB and OTG, being able to simultaneously receive and manage up to 05 wireless transmitters included in 05 different HDW instruments. Some musical instruments (HDW) with different shapes, sizes and functions for each specific use. All these instruments can generate and send any MIDI note, on any one of the 16 MIDI channels, and can then be used simultaneously by multi-users, with patching of different instruments, thus being able to have a “band of disabled musicians” inside a workroom and recovery, on a stage, etc. This results in an excellent level of socialization among the group, and this social interaction can be useful and beneficial for users with disabilities. Among some features and functions, these instruments have individual control and choice of volume, tuning, modulation (with gyroscope, or joystick), octave shift, chords, drum solo, multi or single channel, patch set, distance (in Musical -Beam) etc. We currently have 04 models of instruments in production and commercialization, and we intend to expand these instruments in the network, because the needs are diverse due to the very nature of the diversity of users. - BIG_KBD_25 (Large musical keyboard with 25 large, sensitive and robust keys, with various effects and controls via MIDI commands) - BOARD_SOUND_12 (rectangular music board with 12 colored touch regions + effects + gyroscope) - GIRO_SOUND_09 (round musical board with 09 colored touch regions + effects + gyroscope) - MUSICAL_BEAM_05 – Wireless instrument with 05 laser distance sensors, providing an interaction without physical touch of the person, that is, without a key or physical trigger, extremely useful for people with reduced motor capacity, strength and/or mechanical pointing. Allows playing instruments and performances with simple body movements, for example: wheelchair movement, legs, arms, head, hands, feet, fingers, etc. and without peripherals attached to the human body, such as wristbands, shirts with sensors, etc … , which sometimes bother and are not accepted by users with disabilities. This is a non-invasive process to the user's body. Music generated literally in the air, away from sensors. The 05 distance sensors can be detachable and use "clips" that can be attached to rods, pedestals, supports, table tops, wheelchairs, etc... providing enormous positional versatility to the instrument in relation to the user. The actuation distance of the sensors can be adjusted electronically.
