 ====== Making a vocoder in ams ======
 ===== Introduction =====
-The entire process of setting up things in linux is more than often a hard one. Newbies have to deal with command lines and learning curves which range from steep roads to climbing mountaintops. Small goals like these in this tutorial can help people get confident in using linux.

Small goals like those presented in this tutorial can help people get confident in using linux as their DAW.

 Its goal is to emulate an analogue synth, so learning about one will also help you know the other. Voltage and resistance are replaced by floating point variables, but the emulation is quite accurate, actually.

-This stands for Midi Controlled Voltage. This is where the signals from vkeybd go to and can be sent to other modules.

 This one mixes two inputs and turns it into 1 signal. Useful for turning stereo into mono.

+=== VCO ===
+The Voltage Controlled Oscillator is the most important module when it comes to what your voice is going to sound like through the vocoder. The triangle or saw waves are a good place to start. The Frequency input will be linked to the frequency of the MCV, which results in the wave being the same pitch as what you play in vkeybd.
+=== Linear VCA ===
+The Lin. VCA module may not be what you expect of a Voltage Controlled Amplifier if you see the usage in this context. We'll use it to stop signals going through when there is no key pressed in vkeybd.
+=== Vocoder ===
+The cherry on top of the cake. This filters the "sound" of your voice and only the "information" part of your voice remains. The information in your voice gets mixed with the sound of the carrier. [[http://www.sirlab.de/linux/descr_vocoder.html|Settel can explain this much better than I can.]]

+Here's how you should connect everything in ams:

+It should be pretty straightforward. If you rightclick any module another window opens so you can change some options. Good luck with finding out everything. The vocoder should be set to having 16 bands and you should set all bands to 1. As soon as I find out what every band does I'll put it here. If you do, don't hesitate to put it here.
+There you are. You just saved 300 bucks, if not more. Ready for live or studio usage. Have fun!
+===== Dirty bypass for more "formant" signal =====
+You might be disappointed to how clearly you can hear a sentence. In my surroundings people were disappointed on that matter. I solved it doing this:

+Just make sure you mix the bypass accordingly so you don't hear too much of your own, unvocoded, voice. Unless you want that, of course.
