Description
ChordCalculus is a tool for players of fretted instruments. ChordCalculus will allow the user to choose from a large number of pre-defined fretted instruments in a variety of tunings. Additionally, the user can define new instruments and/or tunings. Single or multiple capos can be added. The user then picks from one of four operating modes using the segmented selectors at the center top of the display:
* (C)hord Calculator:
Show all fingerings for chords for a given instrument/tuning, filters, capos, and fret span.
* Chord (I)dentifer:
For a given instrument/tuning and fingering, display all possible names for a chord
* (S)cale Display:
For an instrument/tuning, key and scale type, display the scale, and play a two-octave scale
* (P)rogression Player:
Derived from chord mode, display fingerings for a chord progression. Also plays chords in sequence.
In all cases, the chords can be played as a chord or arpeggio and the scale played back.
As of version 2.0, an instrument tuner is accessed by long touching the tuning button.

Fixes:
Hopefully catching bad configuration file crashes that are occurring for some users. The app now catches these and resets to factory settings. Please let the developer know if this occurs more than once via the web site.
Enhancements:
Note indicator's red is now "milder". Let the developer know if you prefer this or the "stop light" red version
Now the Tone Locator Filter and the Quick Chord/Root selectors coexist peacefully on the iPhone.

Enhancements:
In Identify Mode, a long touch on the Found Chord Table, will shift you to Chord Mode, with the closest possible chord displayed. The appropriate Tone Filter will be set, based on the selected chord. This is handy for finding other voicings of this identified chord. Going back to Identify Mode will display the notes that where selected. Shifting back to Chord Mode using the main selector clears out the remembered notes.
Fixes:
Partial Capos were allowing some fingerings behind the capo that were not playable.
Chord Identifying was not properly finding some 6th chords.
If the Found Chords list is too long for the screen, an indicator shows more chords below.
Some minor UI tweaks.

Fixes:
Some users on multiple platforms are seeing crashes that are fixed by a reinstall. I have put error reports on all file and iCloud related crashes. Please note the error type and e-mail me via the web site. I will track it down as soon as I have more data. If you want direct feedback, include an email address. I suspect disabling iCloud syncing will also fix it.
Enhancements:
The UI will now more appropriately use the full screen for all iOS platforms (the iPhone 5s is a stretch), thanks to Cartography, a useful framework for constraints. .
Th UI also now includes haptic feedback for various interactions with screen and its elements.
In Chord Mode, long touching the Chord name in the center panel below the play buttons will display all other names for the currently displayed chord (similar to identify mode). Tapping the list (or any other action that changes the fretboard) will remove the list. This was a user request. Other suggestions for enhancements are welcome.
The Instrument quick index is now full names of the sections.

New:
-Progression Mode will now automatically drop the root chord tone in chords where the instrument has insufficient strings
to finger each chord tone.
-The progression display indicates which chords in the progression have dropped the root.
This can be overridden in the filter section (No Auto -35)
- Whenever a chord tone is omitted, either with the chord tone filters or as above, the display of the omitted note is grayed.
- In the Settings panel, there is a button to enable/disable touchVisualization.
When enabled, there is a blue dot that indicates where the screen was touched.
Useful for demos and teaching.
- Now doing a 3-finger tap on the fretboard while in Chord Mode and displaying the chord tone scale will hide/unhide
the accents on the current chord tones. Good for teaching and creating chord position charts.
Fixes:
- Remembering the last configuration is fixed. Got clobbered in 1.44.
- The "Instrument index" is now the same on the iPhone and iPad.
- Various in-app help content has been updated

Fix:
iPhone 6 series incorrectly render the root selector text (too large). Seems to be a bug in the SDK emulator, which renders correctly. Should be fixed. Please e-mail at the developer website if its still wrong.

New:
Now harmonized scales in progressions. These will be added to the"default" configuration only.
These include major, the natural, melodic and harmonic minors, with or without 7ths.
Majors also include an "folk" turnaround (substituting the V7 for the VIIm7b5).
For the major harmonized scales, you also select the "mode" and the progression will start on the proper chord.
For example the Dorian mode of A major starts and returns to Bm
Fixes:
Now the application properly remembers your last configuration and restarts from there.
Some minor cleanups of list formats.
The URL for customer support is more obvious.
A small "jump" in the displays for the XR has been fixed

Configurations that were saved before "courses" were introduced will crash the app when loaded. Now fixed. However, user-created instruments from that configuration will have courses set to off.
Adjusted arrangement of various "setttings" windows for X family iPhones.

Sorry for all the recent updates and glitches in the iPad environment, but was making major improvements to Identify Mode. Now chord section labels are correct and color tones (9th, 11th and 13ths) display on the fretboard (rather than 2nd, 4th and 6ths).
Suggestions to layout and features can be sent from the Developer website.

dAvetioga,
STILL NO CONTACT!!!
Has been a decent app until latest update - now it fails to launch! There is no contact info in the developers page to report this or find a solution!
*UPDATE* Quick turnaround on bug fix! I enjoy the app and the interface is fairly intuitive. I have multiple chord apps and I find this one to be my go to for chording. Keep up the good work!

Dave, very much, FCD,
Crashing
Upgraded rating. Thanks to the developer for his quick response. The app runs fine now. Three stars because the user interface is a bit opaque.
[Original review: Bought this yesterday (7/3/19) and installed it on my phone (iPhone XS Max, iOS 12.3.1). It ran fine then, but subsequent attempts to run the app on the following day failed, with the app crashing after displaying the splash screen. Hard iPhone reset failed to resolve the issue.]

BrianB09,
Help!
UPDATE: Looks like my issue was user error. Cool app, especially for free!
This is a really useful app, and I use it all the time. However, the latest update appears to be non-functional on my iPhone 8+. Specifically, the “Type” menu on the left-most screen has disappeared. This app really is cool, so I hope a fix will be forthcoming. When it works, it’s five stars!
