Midify FAQ

No. Midify has digital outputs, meaning that they are either on or off. A MIDI-CV converter uses a varying voltage on a single output to select the note that is played by the synth, while Midify has a separate output for each note.
It is used to blink an LED indicating that you are in configuration mode, that a command has been received, etc. It can be wired directly to a GBA/DS LED or to a separate LED with a current-limiting resistor. This output is always active-low.
You can power Midify with 3.3v or 5v DC. Each output can handle 25ma, up to 200ma total for all outputs combined. You can drive a few LEDs directly if you want, but if you are planning on driving any larger loads you should use transistors.
We include a 2.5mm phone jack that can be mounted on the outside of your handheld, along with a cable that plugs into this connector and has a standard MIDI plug (5-pin DIN) on the other end.
Yes. There are 12 outputs to solder, plus power-supply and MIDI wires.
The board measures about 1.04" x .04". It's the same size as the GBAccelerator since it has been proven to fit into most Nintendo handhelds.
That's pretty much limited by your imagination and we'll never be able to compile a complete list. As-is it will work with most Nintendo portables and anything that needs a high or low signal. If you use the outputs to drive transistors it opens up more possibilities of devices you can connect Midify to, such as toys and instruments with matrix keypads.
It takes an incoming MIDI stream and turns on and off 1 of 12 different outputs, depending on what note has been played. The outputs can either be active-high or active-low. They are hi-z when they are "off".
