Instant Play 2500 Instruction Manual

Instant Play 2500 is a browser-based instant replay sound player with 50 banks of 50 sound slots (2,500 sounds). Trigger clips, crossfade between them, loop them, trim them, and save your layouts as sessions.

1. Quick Start

  1. Click UPLOAD SOUND (inside the black and green display).
  2. Choose a Bank and Slot, type a Sound Name, pick an audio file, then click SAVE SOUND.
  3. Click the numbered button for that slot. Your sound plays.
  4. Click STOP to stop the last sound, or STOP ALL to stop everything.

2. Free vs. Premium

Free

Premium (log in, then click UPGRADE)

3. The Display

The green display shows:

Use the fullscreen button in the bottom-right corner to enter or leave fullscreen mode. Leaving fullscreen does not stop playback.

4. Playing Sounds

Sound buttons

Each of the 50 buttons is one slot in the current bank. A button shows its slot number, the sound name (or EMPTY), and its state. The small letter beneath each button is its keyboard shortcut. Long sound names scroll within the button, while the sound state stays fixed at the bottom.

Left-click and right-click actions

Use the LEFT-CLICK and RIGHT-CLICK drop-downs to choose what each mouse button does:

Defaults: left-click = PLAY, right-click = CROSSFADE. Your choice is remembered.

Master volume

The MASTER fader controls overall output level.

STOP / STOP ALL

STOP stops the most recently started sound. STOP ALL stops everything.

5. Keyboard Shortcuts

The 50 slots map to the keyboard, 10 per row:

SlotsKeys

11-20Q W E R T Y U I O P
21-30A S D F G H J K L ;

41-50Shift + 1 to 0 (! @ # $ % ^ & * ( ))
KeyAction
SpaceStop the last sound
EscStop all sounds (outside fullscreen)
Shift + SpaceStop all sounds (while fullscreen)

While fullscreen is active, plain Esc exits fullscreen and does not stop sounds. Use Shift + Space or the on-screen STOP ALL button to stop all sounds without leaving fullscreen.

Shortcuts use your Left-Click action and follow whichever mode is active (Bank Select, Edit, Arrange, etc.). They are ignored while you are typing in a text box or drop-down. Holding a key will not retrigger a sound.

6. Transport Controls (Premium)

Transport controls act on the most recently played clip (the display shows "TARGET: LAST").

Target Select

Click TARGET SELECT, then click slot buttons to mark them as targets (they get a gold border). Click TARGET SELECT again to exit and clear the selection.

7. Uploading Sounds

Click the UPLOAD SOUND tab:

  1. Choose a Bank and a Slot.
  2. Type a Sound Name.
  3. Choose an audio file (MP3, WAV, OGG, and other formats your browser supports).
  4. Click SAVE SOUND.

Uploading to a slot that already has a sound replaces that assignment. Free accounts can only choose Bank 01, slots 01-10.

Important: Sounds are stored in your own browser (IndexedDB), not on a server. Sounds you upload while logged out last only until you refresh or close the page. Log in to keep your library and sessions between visits. They stay on the device and browser where you saved them.

8. Sound Editor (Premium)

Trim a clip and set its loop boundaries. To open it:

  1. Click EDIT CLIP. The button reads EDIT ON.
  2. Click the sound button you want to edit. (No audio plays while Edit is on.)
  3. Or click the SOUND EDITOR tab to reopen your last edited sound.

In the editor:

Click EDIT ON again to leave Edit Mode.

9. Sound Library (Premium)

The library holds all your sounds, independent of any bank or slot. Slots simply point at library sounds, so the same sound can appear in several banks.

Adding sounds

Open the SOUND LIBRARY tab, choose one or more audio files, and click ADD TO LIBRARY.

Using library sounds

Click a sound in the list to open its menu:

You can also drag a sound from the list and drop it onto a slot button. Assigning to an occupied slot is refused ("SLOT OCCUPIED"). Moving a sound onto an occupied slot swaps the two.

10. Banks and Arranging Slots

Bank Select

Click BANK SELECT, then click a slot button 01-50 to jump to that bank. The bank number appears at the top left of the display. The app remembers your last bank.

Arrange Slots

Click ARRANGE SLOTS, then click a filled slot:

Click EXIT ARRANGE when finished. Bank Select, Arrange Slots, and Target Select are mutually exclusive: turning one on turns the others off.

11. Sessions (Login Required)

A session is a saved snapshot of which sound sits in which slot of every bank. Session controls remain visible at the bottom of the page and are disabled until you log in:

The last session you saved or loaded is reloaded automatically when you log in.
