What is the OctoSynth you may ask? The octosynth is a polyphonic synthesizer that is able to produce eight Pulse Width Modulated tones that form together a musical scale. In English terms, it is a 8 key electronic organ that can play more than one tone at once but only one scale.
Special thanks to Joe Marshall who wrote the very useful code.
As suggested in the title, it runs on Arduino.
So before we get started, let's see what is sounds like. Shall, we?
And and explanation would be nice.

You will need:
An Arduino
12 Male headers (2 together and another six together. Also, another 4 together(Optional))
8 Unifomly LONG Wires ( By long I don't mean 3 meters but it means a decent 10 inches or maybe, 20 crentimeters.)
A Certain Amount of Copper Tape (Get a roll to be safe)
Enclosure (I used styrofoam as a base but if you want an enclosure, which is totally fine, you can use one. The length will depend on the wideness of you choose.)
Power Jack and Battery

Yeah, I know it isn't capacitive proximity sensing but it is a capacitive touch pad.
i am running into a problem though...i built mine and it only plays the first 3 keys, the remaining keys will play just fine if i touch the 9v battery...any thoughts?
If that checks out, look and see if you have proper connections.
I am using 1.2cm copper tape and they are 1cm apart from each other, I wonder if i am having some sort of capacitance issues. I will record a quick video and post it tomorrow morning
thanks for the instructable.
I do have one question. Is it possible to wire this to a shiftbrite LED and have it play both colors and sound? I looked at the code but my novice level is a major handicap. how do you suggest this can be implemented?
Not really. I have wanted to learn how MIDI works for a long time and what the uses could be...
If someone could write a good article (simpler than Wikipedia and other websites) I would probable try and add MIDI. I still have no idea about its application.
i just sing up on the Instructables site and i mess with the comments ☺

thanks...
Now you just need How-Tos.
(I really like the FA one but I only examined a few. Any suggestions on which ones I should watch?)
To convert it to proper capacitive sensing, put a thin sheet of non-conductive film over the row of keys. You may need to enter a calibration value into the code to set the switching threshold.
One other thing - You say below that you did not write this code. I know the author's name is at the top of it, but you should really give him credit in the Instructable It's very bad form not to do so.
Yep, that's great. I'm more a Picaxe kind of guy, but looking at the Arduino code it appears capable of a lot more. Do you have any plans to extend its capabilities?
I'm currently designing a sort of Stylophone on Steroids with the Picaxe. Hope to be putting together an Instructable in the not too distant future.)
I'm still a learning programmer. I need some time to actually learn how to program. I can edit, but I can't really write.
Between school, homework and tests it is hard to actually get time to devote myself to learning how to program.
I am really willing to see the Stylophone on steroids. I really enjoy your projects especially the tic-tac tunes.
Do you think you could add a button to your tic tac tunes beat box that allows you to add more drum sounds to loop? It would have to sort of be like a Luna Mod except with drum loops and beatboxing being looped. I sadly can only really write simple codes with Picaxe but a lot of code with Parallax Basic Stamp...
