Brief: to develop a working prototype MIDI instrument that controls computer music software. The device will use a microcontroller and will consist of a printed circuit board. The prototype will involve developing the hardware and the software. Using off the shelf components and existing open source code. Requirements: ● Preferably works with an iOS device to operate GarageBand’s virtual instruments ● Velocity sensitive buttons ● A matrix of 28 buttons, which are velocity sensitive and trigger MIDI notes. ● LEDs will light up when buttons are pressed ● The LEDs which light up the buttons need to be multicolor LEDs that light up according to the note. ● Powered by 240V mains You will need to design a working prototype. The final prototype will use an existing microcontroller (Arduino or rasberry Pi) and/or a full printed circuit board. Excellent english skills are a must.

Hi Sir, I am very expert in MIDI processing of music instruments on arduino and raspberry pi. I have developed system for my clients where i have developed MIDI processors on arduino to process MIDI notes and mapped them with applications as outputs. I am very expert in it and i am offering you my services at very low rates. I have designed projects where I have connected arduino and mcu to MIDI connectors or to computers. Please discuss with me so we talk further on it. This bid include circuit design and source code. If you need prototype you have to pay some additional charges. Very much looking forward to hear from you Have A good day! Cheers ! Ahmed

Hello, have a great day. We will ship you fully working hardware with proper enclosure. in first prototype we will use Arduino later on we will remove arduino board and use single AVR chip to reduce the PCB size and fabrication cost. Final deliverable will be compact board equipped with AVR controller perfoming the midi control functions. Please feel free to contact us. Best Regards, Shahbaz.

Hello, I'am research & development engineer in apparel company. I did several arduino projects in the our automation projects. Some are RF trans-receiving projects. Some are SIM900 GSM projects.I have some VB.net applications develop by my self for the Arduino programming without any programming knowledge. Also i have worked with X bee RF module too. I have did some projects by using the USB host shield. I can controll the keyboard,mouse,webcam etc by the usb host shield. I can do the raspberry pi B+ projects. I have one & i can do lot. Kindly give this project for me i'll do my very best for you. Thanks, Renuka
