Controls & navigation

Control-pad, touch, and hardware-keyboard behavior for tracker and native screens.

Main control pad

The pad stays visible across tracker and native iOS screens. The small A, S, and D marks are reminders of the matching hardware-keyboard shortcuts.

The lettered mini navigation map in the pad's open area is also interactive. Swipe it up, down, left, or right to perform the matching NAV+arrow shortcut.

On iPhone, tap NAV four times quickly to open the key-layout menu. Choose Remap, drag keys among the eleven available grid positions, then tap Done in the mini-map cell. Dropping on another key exchanges their positions; dropping in either blank position moves the key there. Choose Default from the four-tap menu to restore the original layout. A custom layout is device-local and remains active after relaunch.

The pad uses the active tracker theme. Button fills, borders, and symbols adjust to the theme colors so the controls remain readable with light and dark themes.

Basic control combinations

GestureMeaning
ARROWSMove the cursor or focus. On native pages, up/down moves rows and left/right moves among controls in a row.
ENTERInsert, activate, open, choose, or confirm the focused item.
ENTER + ARROWEdit a value. Left/right is fine; up/down is coarse.
EDIT + LEFT/RIGHTStep through an alternate or list value, such as an instrument type, mode, preset, or delay division.
NAV + ARROWMove among screens. Left is universal back; right opens more detail.
PLAYStart/stop transport, or audition on sample-oriented screens.
Hold ALTOpen a quick list of the Audio Units loaded in the current project.
Using modifiers

Touch supports button chords. Hold ENTER, EDIT, ALT, or NAV with one finger, tap the second key, then release.

Screen navigation

The tracker’s screens form a map. More detailed musical data is generally to the right. A target must exist before you can open it: a Song cell must contain a chain, and a Chain row must contain a phrase.

CombinationAction
NAV + LEFTBack one screen; close a native page or inline picker.
NAV + RIGHTDrill into detail: Song → Chain → Phrase; Mixer → focused Channel/Master Strip.
NAV + UPFollow the screen map upward, commonly Song → Project.
NAV + DOWNFollow the screen map downward, commonly Song → Mixer.
Tap NAVBack shortcut on GlassTracker-native pages. It remains a no-op on stock tracker screens.

Editing tracker grids

Insert, change, and clear

  • On an empty cell, tap ENTER to insert the last-used value or a new zero value.
  • Hold ENTER and tap left/right to change the value by a small amount. On a four-digit FX value this selects a digit instead — see below.
  • Hold ENTER and tap up/down to change it by a larger amount.
  • Hold EDIT and tap ENTER to clear the current item.

Four-digit FX parameters

A Phrase or Table FX value such as 0000 is one cell, not four. Plain left/right therefore moves between columns: from a Phrase note column, five presses reach the FX2 value.

  • Hold ENTER and tap left/right to select one of the four digits inside the value.
  • Hold ENTER and tap up/down to change the selected digit.
  • The selected digit position is remembered, so it stays where you left it on every other four-digit value.
  • A row with no command still edits its value, which is how you enter a number before choosing the command.

Phrase and Table behave identically here. Build 13 walks digits with plain left/right instead; build 14 restores the behavior described above.

Copy, cut, paste, and clone

CombinationAction
ALT + EDITStart a selection. Use arrows to resize it.
ALT + EDIT twiceExpand selection to the row.
ALT + EDIT three timesExpand selection to the screen.
EDITCopy the active selection.
ALT + ENTERCut a selection; without a selection, cut/paste the current cell.
NAV + ENTERPaste the clipboard at the cursor.
ALT + (EDIT, then ENTER)Clone the selected chain, phrase, table, or instrument to the next unused slot. With ALT+EDIT still held, a second ENTER clones again.

Transport, solo, and mute

CombinationAction
PLAYStart or stop playback. The exact scope depends on Song/Live mode and current screen; on native pages that are not part of the tracker screen map it is always the song transport.
Hold PLAY for 2 secondsEmergency stop: stop transport, clear queued MIDI, send All Sound Off / Reset Controllers to external and hosted destinations, and silence the AU graph.
ALT + PLAYQueue or audition the current row, depending on screen.
EDIT + PLAYOpen Record from its supported source screens; pressing the same chord on Record returns to the screen that opened it.
NAV + ENTERSolo the focused channel.
NAV + EDITMute the focused channel.
ALT + NAVClear all solo and mute states.
ALT + LEFT/RIGHTNudge song tempo down/up from the Song screen.

Solo/mute release order matters on tracker grids: releasing NAV first latches the state; releasing the action first makes it momentary.

Native pages and lists

AU Rack, Add AU, Sample Pool, Instrument Pool, Channel/Master strips, parameter editors, and CC maps replace only the display area. The control pad stays visible.

  • Use up/down to move through a list and ENTER to choose.
  • In a row with several controls side by side, use left/right to move between them. Left/right stays inside the row: it stops at the row’s first and last control rather than spilling into the row above or below.
  • PLAY starts and stops the song from these pages and from their pickers, so you can audition the arrangement while working in the AU Rack, the Sample and Instrument Pools, or a channel strip.
  • Use ENTER+arrows to adjust sliders and numeric controls.
  • In AU Rack, a slot's CH button opens both LISTENS ON and DELIVERS AS. The page-level Advanced Options switch reveals MIDI Nudge and MIDI Clock without changing their saved values.
  • Device pages, including MIDI Ports and MIDI Input, retain the bottom navigation and control pad while their settings are open.
  • Touch sliders respond to horizontal drags while vertical drags keep scrolling. Instrument volume, pan, and detune settle slightly at their neutral mark and provide one haptic when the center detent is reached.
  • Press down while a search field is focused to dismiss the keyboard and return to the currently highlighted list row.
  • Tapping outside a search field dismisses the system keyboard.
  • Use NAV+left to close the topmost page. A bare NAV tap and NAV+up/down/right are inert on these disconnected pages.

Sample editor and slices

CombinationAction
ENTER + LEFT/RIGHTMove Start/End or a selected slice by one frame; hold to accelerate.
ENTER + UP/DOWNMove by 1/64 of the file.
EDIT + UP/DOWNZoom the waveform around the selected marker.
LEFT/RIGHTWalk slice markers and the parked playhead.
PLAYAudition from the selected marker or playhead. Holding can audition until release.
ENTERDrop the parked playhead as a slice marker.
EDIT + ENTERDelete the selected non-zero marker.
