Chord Stacking

  • New & Improved Chord Stacking Logic
    • xoxox ... automatic Capitalization of 1st letter, when not set
    • xooXox ... capital letter defines pattern offset (=index)
    • xooOox ... index can also be non-active (=silent index, capital letter "O")
    • xoo(x)ox ... silent index can be also set by parentheses
    • xoo60ox ... rootDIGIT defines the exact static MIDI#number target
    • xooF#ox ... rootCHAR represents the target tonic, 'floating' across all +/- octaves
    • [xoo60ox] ... square brackets make the enclosed pattern static/locked in place
    • Xoxox xoO ... multiple pattern strings can be used
    • {Xoxox, xoO} ... alternatively several other glyphs can be used for clarity
    • F ... rootCHAR standalone or with trailing "/" and scaleModifier string results in global tonic switching
    • /xoxoxxoxoxox ... scaleModifier strings with a leading "/" result in global scale switching. these strings must match the 12-glyph x/o-Modifier Syntax and can be also copied by clicking on the ScaleModifier label
    • G#/xoxoxxoxoxox ... tonic and scale switching can be also combined and already copied like that by ALT+Click on the scaleModifier label
    • Various other usage examples:
      • xoxox
      • xooCox
      • [xoo60ox]
      • xoF#ox
      • xoxoo(O)oooox

      • xoo[60]ox
      • xoo[xo60ox]
      • F#/xoxooxoxooxo xoo[xo60ox]-1 xoooooO
      • Automated Header Switching Arrangements:
        • Header#54: [56] C#/xoxoxxoxoxox xoCox-2
        • Header#56: [58] C#/xoxoxxoxoxox xoCox
        • Header#58: [54] C#/xoxoxxoxoxox xoCox-1

      • etc,

Dynamic Help Mode

  • toggling the HelpButton ON enables dynamic help cards when hovering particular key elements
  • HelpCards will stay open as long as hovered and may have images and/or interactive elements embedded
  • these HelpCards are sourced from AutoTonic's API and therefore subject to change (new entries will appear with time and effort)
  • Because the new Help Mode includes a framework for embedding web content, the application size has increased by about 15 MB. While this is a slight drawback, it doesn’t affect the application’s speed since the extra resources are only used when Help Mode is active (the size doesn't cause any difficulties in running). Having an up-to-date, interactive in-app help guide makes this small space increase worthwhile. If you prefer a smaller version, I’m considering creating a lightweight alternative. Please email me if you’re interested, so I can gauge demand.

Custom Colors

  • AutoTonic's UI Appearance can now be modified by tweaking certain color parameters inside a reference .txt file called AutoTonicSkin.txt
  • if it doesn't exist a new .txt file with default parameters is created on launch, in AutoTonic's default user folder, here ...
    • Mac: /Users/YourName/Library/Application Support/AutoTonic/AutoTonicSkin.txt
    • Win: C:\Users\YourName\AppData\Local\AutoTonic\AutoTonic\AutoTonicSkin.txt
  • the default's .txt file's first block represents the currently active UI color scheme
  • other default example color scheme's can be found later in the document (eg, for copy & paste) or saved and edited manually there
  • in AutoTonic ALT+Click on the RESTART label opens the .txt document with the system's default text editor (it's advised to preview color modifications immediately by simply clicking the `RESTART' button to apply the changes and relaich zhe application automatically)
  • changes are permanently stored and recalled/remembered on application launch
  • to reset any changes the .txt file can be simply deleted (eg, by moving it to the trash), a new file with the default parameters will be created on application launch

2023-03-16 / v1.13 (Beta Version Release)

Nuke Mode

Introducing NUKE Mode, a new feature that unlocks a whole new way to play music with AutoTonic. With an all-white keys input keyboard layout and an innovative alternate keyboard concept, NUKE Mode allows you to play even on black keys. Simply toggle it on by clicking on the lower right screw or by using the shortcut "N".
NUKE Mode also enables you to feed existing pieces of music through AutoTonic and reharmonize them in real-time. I've had a blast experimenting with various titles, from Nothing Else Matters to Beethoven's Mondscheinsonate Nr. 14 or Smells Like Teen Spirit by Nirvana. NUKE Mode even temporarily handles pitch offsets when the source material has momentary ascending or descending runs.
With NUKE Mode, anyone can hit any major, minor, fourth, or other chords they may already be familiar with without losing the context of the initial finger pattern-ratio in perspective to the resulting transpositions. Although I don't have much documentation on it yet, once you switch it on, it converts all black keys into playing keys as well.
However, there are some known bugs with NUKE Mode. It still doesn't work with PIVOT key switchings and/or x/o-patterns, and there are several improvements that could be made in how it chooses where the target note of any incoming black key lands. These issues are case-specific and will require some more time to resolve.

Scale- & TonicModifier Widget

These two new modifier widgets now displays the current settings below the modifier panel and allows you to copy them by clicking on them. In addition, you can now drag and drop SongMarkers to create MIDI files on the fly, which is useful for recalling from DAW. This feature requires AutoTonic to be routed to receive signals from the port that the DAW's channel is sending to.

Tonic/Scale Learn

AutoTonic now also supports getting recalled/programmed from external sources. MIDI notes 0-11 (C-2 to B-2) trigger the tonic change, while MIDI notes 109-119 (C#7 to B7) trigger the scale modifier change. This enables real-time reverse learning of any tonic/scale scenario, which can be recorded directly into a DAW and recalled from there.

CenterScreen Indicator

The CenterScreen now displays the current Scale-/Tonic-Settings when in CleanMode (which can be toggled to be shown). This is particularly useful for users who found the headers too small before.

Pin-On-Top

Also, there is now a new button that allows the application window to stay on top of all other windows. Simply click on the new PIN needle on the top left to activate it.

Restore the global window's position on close/open (finally!)

This feature will restore the position of the application window to its previous location when the program is closed and reopened.

Resize UI (Experimental)

This experimental feature adds new buttons to resize the entire application window, addressing a common request from users who wanted to see the Headers/UI larger and higher rendered. However, some features, such as MIDI IN/OUT scroll wheels and pin-on-top, are currently disabled. Note that resizing the window multiple times in a row may cause some wobbling and bugs.

Window Tiling

This feature allows users to fold and expand the three main sections of AutoTonic: InputKeyboard, CenterScreen, and OutputKeyboard. With the arrow buttons on the left, users can toggle the corresponding panel to shrink or expand the application window, giving them the option to focus on a specific section while working on other tasks.

Cheesegrinder Mode (Experimental)

This mode cuts off notes immediately after any note ON signal. It can be enabled by clicking on the lower left bolt in the center screen. It's a fun and inspirational feature to use!

New Shortcuts

  • "N" toggles the NUKE Mode
  • CMD/CTRL + "+" (Plus) or "-" (Minus) toggles the Resize UI. CMD/CTRL + Return resets it.
  • Clicking on Scale- and/or TonicModifier copies their data.
  • Holding down ALT while clicking on the Scale- & TonicModifier Widget copies data in another format.
  • Dragging from the Scale- & TonicModifier Widget creates a MIDI file on the fly (as mentioned above).
  • Holding ALT while dragging from the Scale- & TonicModifier Widgets exports alternate MIDI file(s).

And More

  • This Release was not signed, so you'll have to allow it grant access through the system preferences Security & Privacy > General > Allow App/ Open Anyway (…)
  • Bug fixes, minor improvements, and more.


2020-11-19 / v1.12.3, silent update (mainly bugfixes)

  • build fixes
  • fix credits screen bug
  • (v3)

2020-10-22 / v1.12 #MIRROR

Turn the World Upside Down

This update will introduce a new MirrorKeys feature that allows to completely flip the playing upside down (so high notes to the left and vice versa with the low ones) \u2026 this feels incredible inspiring to use and I am really thrilled to share this with all of you finally. You can think of it in terms of a lefthand-keyboard, which can be assigned to AutoTonic's true 'modal' mapping.

Enhanced Signal Path

I am working on the code now all by myself finally and things just take sometimes longer than expected, as everything also got even more complex with every new change. But I've changed the main logic for the signal routing and now you will only see the according channel#1-16 signals when the ScrollWheels are set equally. This not only avoids any potential note hanging with interferring MIDI channels, but also brings wonderful new techniques to life.

AutoTonic v1.12 – NEW #ЯЯOЯIM Keys
Watch the introduction on YouTube:
AutoTonic v1.12 – NEW #ЯЯOЯIM Keys

  • MULTI mode for Headers --> when "MULTI" is ON then Headers will listen to all #1-16 midi channels, like no matter what channel currently is selected at the input scrollwheel
  • OMNI/FILTER/THRU Signal Path improvements --> will route signals more accurate now, bugfixes
  • MONOPHONIC/POLYPHONIC input mode, can be especially useful when used in combination with x/o-Stackings
  • DELAY feature for offseting incoming note signals by milliseconds, which is especially useful when using 'control instances' for automatic chord triggerings --> so Header switchings can be triggered before the actual incoming note press
    • DELAY can be set from 0-999 ms
    • ALT+click on DELAY will reset to "0"
    • use clickdrag or double-click for numerical entry
    • when POWER=Off both, black and white keys are delayed
  • New output routing methods: "CH.#" (current selected output channel) or "ALL" (Sends to Ch.#1-16 simulatenously)
  • PANIC feature (can be send to "CH.#" or "ALL"), ALT+click on PANIC sends Note Off signals to all #1-16 midi channels
  • ALT+click on Scrollwheel = reset to channel i/o-settings to "1-OMNI"/"AUTO-1"
  • Performance improvements, Bugfixes and again UI changes. Once again, the sidepanel and many technical features under the hood have been overdone/improved, adding new useful features, a much clearer appearance and countless new possibilities …
  • New Shortcuts:
    • ALT+Return = Reset Database - ALT+Backspace = Reset Setup - Key C = Send out PANIC - PANIC is now improved, by sending all appropriate 'All Notes Off', 'All Sound Off' and 'Reset All Controllers' commands, by default on Channel#1-16. And if PANIC is clicked with ALT pressed it will only send out to the current Output-Channel (=Output Scrollwheel)


2020-06-23 / v1.11 #PivotKeySwitching

AutoTonic v1.11 Pivot Key Switching

Pivot Key Switching

AutoTonic Update v1.11 introduces a new "Pivot Modulation" feature, which allows now to assign "PivotSets" (Hey, think of them as "hot keys") for instant modulation during your input playing -- you can now create harmonic changings of the most complex nature without the need of any additional gestures.

AutoTonic v1.11

Another first: TRUE PIVOT MODULATION

Sounds complex? It really isn't, simply hold down the ALT key to enter "PivotLearn" mode and while keep pressing you can now select by mouse (or midi input) any custom white key or combination of white keys that should become the newly assigned toggle switches for your current selected Header. A red overlay will indicate the assignments. Once you exit this learn mode AutoTonic will automatically trigger that exact black key's Header always when you come across these learned white keys.

BEST UPDATE since its launch

You can assign for every existing Header any combination of white keys to set up your custom tonal modulations and additionally it is also highly suggested to make use of the previously added "Delay" feature to compensate for any computing latency upfront to the actual key switching and therefore enable instant chord modulations ... so newly played chords can already appear transposed, instantly on first triggering (very creative to use!).

  • a decision is made: I'll develop this!
  • coding start (back then by hiring freelancers through "UpWork")
  • start patent filing

~ 2011-2012 / Initial Idea


As a result of trying to learn jazzy piano chords and various scales (in the high-times of an EDM era lol,) I ask myself, why the Piano has to look as it is today and start challenging myself if there wouldn't be other design approaches feasible as well … after discussing it with friends over and over again I develop a custom prototype by script-like approaches and using Logic Pro's "Environment" (version 9 back then? which I still use btw.) … throughout looking into the topic of mapping scales linearly out onto the white keys over and over again, I finally discover the idea of using the remaining (left-over) black keys as function toggles/key switches.
