  • *I'm sorry the function of editing Automation is very primitive so far. I hope I can improve it in future releases.

4-1 Automation Edit Screen

On Automation Edit Screen you can edit the Automation data.
Automation is written in plain text format.
The operation to write text on the editor is the same as iPhone/iPod Touch's standard operation.

  • *Automation Edit Screen appears in Portrait direction because the list of data tends to extend vertically.

4-2 Automation Description Format

The format of Automation is like following:

time, key, scale time, key, scale
time, key, scale
time, key, scale


The time to change key/scale. The unit is [second], decimals are accepted. You can write the decimals as precise as you can, but consider that the time resolution of Automation is about 0.1 sec.


Write with the combination of one capital letter and “#”, like “C#”.
Flat mark cannot be accepted. Please write as “D#” if you want to assign E-flat key.


Write in Roman characters. See “4-3 Available scale” for the detail.
Note that wrong spelling will be ignored. Also note that it's case sensitive.

  • *Data must be placed according to time sequence. Earlier time upward.
  • *Separate columns by comma. Do not insert spaces before/after commas.
  • *You can omit the scale assignment if you only want to change the key. But you cannot omit the comma. ex) 1.23,C#,
  • *You can omit the key assignment in the same way. ex) 4-56,,Diatonic

4-3 Available scale

The scales you can assign in your Automation is following:

: minor pentatonic with blue notes
: diatonic
: diatonic for IM7 context
: diatonic for IIM7 context
: diatonic for V7 context
: altered scale
: altered scale transposed for VI7 context
Harmonic Minor
: harmonic minor
: spanish scale
: arabic scale
: pure pentatonic
: okinawan scale

Most of the scales are the same with the scales available on Drawer, but Diatonic and Altered have the variations that have slightly different function. The variations can be used only in Automation.

  • Diatonic
    Diatonic has 4 variations. All of them has the same scale notes but they have different Stable Notes (*see below).
    : All the scale notes are stable.
    : II, III, V, majVII are stable so that match IM7 context
    : I, II, IV, VI are stable so that match IIm7 context
    : II, IV, V, najVII are stable so that match V7 context
  • Altered
    Altered has 2 variations. Altered6 is introduced so that you can save the time when VI7 appears often, like in Cyclic Chords etc.
    : So-called altered scale, matches V7 context.
    : Transposed 1 note up from Altered, so that match VI7 context.
  • * Stable Position and Passing Position Each scale has Stable Position and Passing Position.
    Stable Position is the notes that are important in decide the scale's tonality, Passing Position, in other hand, is the notes that can be passed temporally but may spoil the tonality when played in longer duration.

4-4 Caution and Tips about Automation

The place Automation data is savedThe Automation data is stored in YMCK Player's application data, apart from your iPod Library's music data. Therefore, once you uninstall YMCK Player all the Automation data will be removed along with the application itself. Be sure to make backups often, especially when you're making a big amount of data. You can make backups by copying the text on the Automation Edit Screen and send it by email etc.

Tips 1To make complex automation data, it's better to edit the text on your PC with certain kind of spread sheet application first, then transfer it via email or your personal server. It is also a good way to make backups.

Tips 2When opening Automation Edit Screen for the song with no automation data yet, YMCK Player automatically insert current key and scale as the first data. If the song requires only one key/scale, and had already found it on the main screen, just open Automation Edit Screen, press [Done] and you can finish setting Automation.
