 Scale and half-tone transposition can be combined. First the scale is changed, then the semitone.
 These combinations open up many creative possibilities!
 
+
+==== Measure Modifications: Transposition and Rhythm
+
+The following functions can be looked up in the Edit menu at any time, but cannot be invoked
+directly from there, but require the use of keyboard and mouse at the same time. Use the keys while
+hovering the mouse pointer over a measure in the track editor (upper half of the screen).
+
+For each of the following four possibilities there is a separate key to increase a value (e.g.
+semitones) or, together with the shift key, to decrease the value.
+
+In the measures themselves, there is a small lettering that shows the current values. There is
+graphically only space for 3 of 4 modifications, but this is not a limitation in practice.
+
+The modifications always apply to an individual bar and are not visible in the pattern (lower part
+of the screen). If the bar is switched off (and on again), the modification is deleted.
+
+
+
+===== Halftone transposition
+
+Halftone transposition (H / Shift+H) changes all notes in this individual bar by e.g. +5h, that is
+five semitones upwards: C becomes F, MIDI note 60 becomes 65. -7h is a fifth downwards.
+
+The scale transposition is calculated first and then the semitone transposition.
+
+
+===== Scale transposition
+
+Scale transposition (S / Shift+S) raises, or lowers, everything to the notes that follow next in
+the respective scale.
+
+One can imagine that the steps in the pattern are shifted up or down in the rows behind the scenes.
+Whatever tone is set in this row gets played. With a normal scale, this is musically easy to
+understand: The tones are moved up or down in the scale.
+
+However, if the scale is chosen freely, there are non-intuitive outcomes; "up and down" with
+respect to pitches may lose their meaning. It is possible to use two interleaved scales in the
+pattern and to switch between them by scale transposition +1. Or even uses completely different
+tones, so that only the rhythm remains the same.
+
+The scale transposition is calculated first and then the semitone transposition.
+
+
+===== Step delay
+
+Step delay (D / Shift+D) makes all notes of the bar sound earlier or later than they are created in
+the pattern itself. The rhythmic consequence is determined by the time signature and subgrouping of
+the track. Example: If the step delay is set to "2", a tone in column 3 will not sound until column
+5. Negative values move them earlier accordingly.
+
+Tones that would sound earlier than 0 or would be shifted behind the end of the bar are ignored at
+first. But if you activate "Step delay wrap-around" in the context menu (right click) of the track,
+these tones are moved to the beginning or end of the bar, like on a cylinder, whose end is followed
+by the beginning again.
+
+The step delay is calculated first and then the augmentation factor.
+
+
+===== Augmentation factor
+
+The augmentation factor (A / Shift+A) doubles (x2, x4, x8, x16 ...) or halves (quarters, eighths
+...) all note lengths of the bar. Subsequent notes are played earlier or later as a result.
+Augmentation means lengthening and diminution means shortening all note values by a factor.
+
+Tones that would sound earlier than 0 or would be shifted to the end of the bar are ignored at
+first. But if you switch on "Repeat diminuated patterns in itself" in the context menu (right
+click) of the track, a halved bar is played twice in quick succession, a quartered bar four times
+in quick succession and so on. This setting has no effect on augmented bars.
+
+The step delay is calculated first and then the augmentation factor.
+
+
+==== Track Groups
+
+Tracks can be grouped together. This is not to be confused with the rhythm groups of patters.
+
+Groups have two properties: they improve the clarity of layout and group JACK midiports together.
+(All tracks in a group send via the same port).
+
+Typically, groups are used to combine individual tracks into "logical instruments". It is highly
+recommended to use groups,  that's why the empty Patroneo project is already set up that way.
+
+Double-clicking on the name of the group "opens" and "closes" it, which has no effect on the music,
+but is purely visual.
+
+Groups can be moved by using their arrow symbol located on the far left (hold down the left mouse
+button and drag up or down), just like the individual tracks. The order of tracks within the group
+is also arbitrary.
+
+Groups and individual tracks can be mixed in any order.
+
+All options and functions for track groups can be accesesd via the context menu of a track (right
+mouse click):
+
+* Tracks can be added to, moved to or removed from existing groups at any time.
+* A track can be moved into a newly created group, which can be given a name immediately.
+* If a track is removed from a group, it becomes a standalone one again.
+* If a track is cloned, it is in the same group as the original.
+* New, empty tracks (those with random numbers as names) are initially not assigned to a group.

+=== Miscellaneous
+
+==== Global rhythm offset
+
+In the Edit menu you will find the Global Rhythm Offset. In modular music production with several
+programs, synchronised by JACK transport, Patroneo can be shifted entirely backwards (or even
+forwards) on the timeline.
+
+For example, a performance is conceivable and the Patroneo song should only start at 52:00. Or you
+want to make a bar- and rhythmless intro in another program, which lasts exactly XY miditicks.
+
+This command is explicitly aimed at advanced users and is documented in detail in the application
+itself when you use the menu command.
+
+==== Hardware: AKAI APCmini
+
+The AKAI APCmini can be used as an input device.  Patroneo has a JACK-Midi input and output port for this purpose: once for the actual input and then back to the unit to control its LEDs.
+
+A video says more than a thousand words:
+
+#TODO Video!
+
+It may seem strange that this is only offered for one specific device. You may even wonder if you
+should buy this device yourself now?
+
+No, don't buy it. Working on the computer itself is faster and more convenient.
+
+The author tried it out as an experiment. The APCmini was the cheapest device of this kind (69€ as
+of 2021) with at least 8 by 8 buttons (standard layout of the Patroneo pattern). There are no plans
+to buy more devices of this kind, so there will be no software support.
+
+In Patroneo, you can only do pattern input with the APCmini. Everything that has to do with tracks,
+as well as measure modifications (transposition etc.), the selection of the scale, time signature
+and grouping etc. must still be done on the computer. And even then, the handling of
+volume/velocity is inconvenient and tone lengths cannot be adjusted as finely.
+
+Once the programming was done, however, it was not worth leaving the functionality out of the
+program. After all, it is Patroneo's only remote control from the outside, which can perhaps be
+"abused" for other creative purposes at some point.

+Es mag ihnen vielleicht seltsam vorkommen, dass das nur für ein spezifisches Gerät angeboten wird.
+Vielleicht fragen Sie sich sogar, ob sie dieses Gerät jetzt selbst kaufen sollten?
+
+Nein, kaufen Sie es nicht. Die Arbeit am Computer selbst ist schneller und bequemer.
+
+Der Autor hat es als Experiment ausprobiert. Das APCmini war dabei das günstigste Gerät (69€. Stand
+2021) dieser Art mit mindestens 8 mal 8 Knöpfen (Standardlayout des Patroneo-Musters). Es ist nicht
+geplant weitere Geräte dieser Art zu kaufen, von daher wird es auch keinen Softwaresupport geben.
+
+In Patroneo kann man mit dem APCmini nur die Mustereingabe durchführen. Alles was mit Spuren zu tun
+hat, sowie Taktmodifikation (Transposition etc.), der Auswahl der Skala, Taktart und Gruppierung
+etc. muss weiterhin am Computer gemacht werden. Und selbst dann ist die Handhabung von
+Lautstärke/Velocity umständlicher und Tonlängen können nicht so fein einjustiert werden.
+
+Einmal fertig programmiert war es dann aber auch zu schade die Funktionalität außen vor zu lassen. Es
+ist immerhin die einzige Fernsteuerung Patroneos von außen, die vielleicht irgendwann für andere
