Hello everyone, I'm starting now and have a Teensy ++ 2.0. The idea is to create a pedal midi controller. I will use with an ipad with a powered hub and two interfaces (midi and audio).
In Windows 7 already installed Arduino 1.06, Teensyduino 1.21, Teensy.
Now I need to know what to buy. Initially will be 25 push buttons without locks, only to turn on and off the midi commands "control change" in two apps on iOS.
Obs .: I know nothing about capacitors or resistors, so would like help from your friends. :)
thank you
 
The easiest way to interface with the iPad and not having to deal with MFI by Apple is using BLE (Bluetooth Low Energy) or will you interface your pedal from the midi device? What messages does it need to send? I have done work on MIDI back in 1999 / 2000 so know at least partially how it works.

Hi jakorten,
I want to replace a pedal Behringer FCB1010 that is connected via USB hub in a lightning adapter. it sends CC # command (control change) to perform actions in the application. I saw several articles and videos that this is possible, but each project has its own peculiarities. my initial questions are very basic, as the issue of connection of wires and transistors or capacitors to be used.

Ah I see, here is a good tutorial that you probably already found: https://www.pjrc.com/teensy/td_midi.html

Don't worry about transistors and capacitors, I think you will only need knobs and resistors, and a few 74HC4051 chips maybe? (or some other expander chip).

Yes, the codes are the fun part of the story. am collecting multiple samples to study. for hardware, I guess to start, only a small box with several push buttons, and access to mini usb teensy. nothing more than that.
