== Creating an Audio Freezer from Scratch ==

The goal here is to use the Sample Record (Looper) as a "poor man's  Audio Freezer" and demonstrate how a traditional audio effect can be used to manipulate CV signal.

== Building an FM Synth ==

The goal here is to build a basic FM voice (1 modulator/1 Carrier) with external 1/v octave tracking using available units.

{{note|A phone call came in and cutoff the last bit of the vid..    the only thing i was going to add is you could go to the modulator sin osc. and modulate that with ANOTHER sin osc.. and on and on it goes down the rabbit hole! :)}}
* Using Mixer Channel unit
* Using the Sine unit
* Using the VCA unit
* Using the ADSR unit
* Using the Offset unit
* Using the Ladder Filter and Clocked Delay for effect
* Running OS v0.1.5p22)

== Parallel Audio Processing Hints ==

The goal here is to use multiple blocks to process signals in Parallel.
Running OS v0.1.5p23)
{{note|As of OS v0.1.6prepatch11 you can now choose the audio output from the source menu instead of physically patching an output to an input.  Nice!!}}

== Custom Units Overview ==

A glimpse of some updates:
* Bypass
* Category Filter

<youtube>https://youtu.be/b4Noh61GKr8</youtube>

== The Poor Man's Vocoder ==
* Running OS v0.1.6pre11)
* Can a Vocoder be built out of units even if we don't have bandpass filters? (barely but it sounds interesting)
* Modules used:  Mixer Channels,  Sine Osc, Envelope Follower,  EQ,  Ladder Filter,  Quantizer,  Custom Unit,  Sample Looper

<youtube>https://youtu.be/o_9mBsExbB4</youtube>

== Creating Long Envelopes ==
* Running OS v0.1.6pre11
* How to cheat and make Envelopes longer than the current 1 second limit
{{note|As of maybe an hour after I made this video,  Brian  has released a patch upping the timings to 10 seconds for attack, decay and release.!!! :D  So this vid is irrelevant for increasing ADSR envelope timing.  However,  keep in mind you can have some more interesting CV shapes and wiggles recorded... and adjusting the player speed will affect the rate of this CV data!}}
