Use your fingers to finger-paint notes on a grid. There are three types of grid: percussion, multi (MIDI instruments), and sampler. On the percussion grid each hrorizontal row represents a percussion sound. The vertical columns represent beats. The entire thing is referred to as a chunk, which is important because you can keep adding chunks.
When you choose the Multi tab from the tab bar at the bottom, you get another grid, for normal instruments, that behaves differently than the percussion grid. These instruments need pitch values for each note, so each horizontal row represents a pitch. The columns are the same as for percussion; they represent rhythmic beats.
A third grid type is found on the Sampler tab. Here you have the ability to record audio clips using the microphone, than assign them notes, including pitch shifts which are represented again by the horizontal rows. Most vocal sounds will make you laugh. They sound like The Chipmunks, or like Darth Vader.
Other recorded sounds could be more serious. Like the sound of a glass clinking, or the pop of a champagne cork. The Sampler is pretty experimental.
You may notice that there are three play buttons (each with a corresponding "paws" button). The one near the top of the screen is for playing the current chunk. It will loop until the "paws" button is hit, allowing you to add (or erase) notes while it is playing. I will explain the other two when I explain tracks, and arrangements.
Working with Tracks
The horizontal area just below the grid is for creating and editing tracks. There are eight very small buttons on the left, followed by an area to the right of that where chunks are sequenced into a track. The small buttons left to right are: Play, and below that Paws, New Chunk (+) and below that Delete Chunk (x), Begin repeat, and below that End Repeat, Increase Repeat Counter (up arrow) and below that Decrease Repeat Counter (down arrow).
Working with Arrangements
The row of controls right above the bottom tab bar is used for controlling playback of arrangements. Arrangements include percussion, instruments, and samples.
Saving and Sharing Jams
The Share tab allows you to save and load locally to and from your device, add friends and send them a jam (which they can edit and send back), and also to publish jams for all users to see, and maybe add to and republish under a new name (yours stays uneditied).
Jamulator: Design and Coding
Each of the three grid views, Drums, Multi, and Sampler, has a common architecture. The segue from the root view (tab bar) controller presents an instance of PlaybackViewController, which houses the tool bar for playback controls and such. Each PlaybackViewController also has two container views: one for a note editing grid, along with it's corresponding controls, and one for track editing and control.
The track editing and control view (aka the loop thumbnail manager) has buttons on the left, and a container view on the right which contains a collection view of thumbnails for each of the clips (chunks) in a track.

- What is it?: A Jazz oriented iPad instrument
- Client: Roy Pertchik
- Tools: Swift 3.2, Xcode 9 beta, iOS 11
- Status: in the iOS App Store
Argyle Keyboard, named for it's hexagonal pattern reminiscent of argyle socks, provides a unique and dynamic musical instrument experience. It is especially suited to jazz in several ways. Based on chord theory popularized by Barry Harris, the keyboard is designed for pivoting around diminished chord and scales. Without going into too much detail, diminished chords are commonly substituted for dominant 7th chords, and are especially suited to moving between these dominants because they are the same harmonic distance from related dominants.
Argyle Keyboard is designed with a wealth of controls that change the notes available for playing while masking out notes that are undesirable.
As a song moves through a chord progression you use these controls to change the available notes on the keyboard. It's as if an autoharp and a pedal steel guitar had a child who was really into jazz ;)

Git commands
Create a remote repo from a local repo
First create it on github with no readme, then
git remote add origin https://github.com/brazford/crazytalk.git
Clone a repo from github, then view all branches, then create a local branch tracking a remote one (a different branch from the one you cloned which is usually master)
git clone git@github.com:OWNER/repo-mame
git branch -a
git checkout branch-name
Throw away uncomitted changes:
git reset --hard HEAD
Delete local and remote branch git push --delete
git branch -d
Using Google AdMob to put a Banner Ad in an iOS App: 2018
Create or log into a Google account
Sign up for AdMob at https://admob.google.com/home/
Ad an App (you need this to be already registered in iTunes Connect to be sure the name is actually available)
Add an Ad Unit
Note the AppID and the AdUnitID for use in your app's code
Create iOS app in XCode
Make sure Cocoapods in installed
Create a Podfile
target 'appname' do
pod 'Google-Mobile-Ads-SDK'
end
on the command line, cd to project, pod install
put import GoogleMobileAds in AppDelegate
in didFinishLaunching, GADMobileAds.configure(withApplicationID: "YOUR_ADMOB_APP_ID")
Develop using Google's test ad ID: ca-app-pub-3940256099942544/2934735716
Set up payment info. Note that Safari didn't work for me, but Chrome did.
Note: I encoutered a bug where Ads displayed in views controlled by a UITabBarController failed to hide if I set a starting index (other than the default of zero) in viewDidLoad(). Very puzzling! I moved that line to viewDidAppear() and the problem went away.

- What is it?: A microcontroller driven battery charger for prolonging battery life

RealTouch: 2005 - 2007
- What is it?: Haptic hardware synchronized with streaming video
- Client: AEBN
- Tools: C#, Microsoft Video Tools, Flash Streaming Server, C++, Director/Lingo, Flash/Actionscript
I needed to be able to send and receive commands from a HID/USB device and transmit them over a data channel that was synchronized with streaming video.
In order to write extensive code for a command scripting language in C#, I wrote some glue in C++ to create a Macromedia Director/Lingo plugin that would
fire up the .NET runtime and execute C# code. The director app(s) had to be embedded in Flash and accessed via Actionscript. Once the proof of concept
was sold to AEBN, I re-implemented all of this using Microsoft streaming technology.

Bio
Born and raised in Silicon Valley, son of an inventor and an English professor, I’ve run Eric Ford Consulting since leaving Apple in 1996. I worked at Apple for ten years,
exactly when John Scully was CEO. So I missed out on Steve Jobs on both ends.
I am a life-long musician, but I've never wanted to make that my career. I own a wide variety of musical instruments which I play with a wide variety of skill levels.
And still I would like more. Learning how to play bagpipes and sitar are both on my bucket list.
I am a student of chess history, and I also enjoy games derived from chess (known as chess variants).
I've taken on a multi-year project of playing through all of the games of all of the world chess champions.
I live in Petaluma California with Louise, my girlfriend of many years, and her 17 year old son Chris, who is also a multi-instrumentalist. He's one of my best friends.
I grew up in Palo Alto, and I still have many friends in the area. I went to an alternative high school, and I have very little college education, prefering to learn
things on my own.
I read fiction quite a bit.
I have dabbled in spirituality. My orientation could be loosely described as a synthesis of sufism and buddhism.
