nedwaves Loopt Manual

intro

Originally an interface to the Digitech JamMan (www.digitech.com) , includes features for managing a library of loops.

The app acts like a finder, but keeps track of each loop's name, tempo, etc.  It adds a harmless "md.txt" file to each directory to hold the information.

If the jamman is attached (via usb) when the app is launched, it will open to the jamman memory card.

The app assumes that consecutive loops of the exact same length go together.  They are displayed as a group, and changes to one are applied to all, unless this feature is disabled.

Basic functions

name or rename

Select a loop and press 'return' (or choose Edit/Rename from the menu).

If multiple loops are selected, provide a stem name, such as that day's date.  The loops are named sequentially.

make a catalog

Choose File/Text Catalog from the menu to create a printable text file showing the names and numbers of your loops.  File/HTML Catalog will create a double-column html version.

adjust jamman settings

Tempo and time signature are adjusted in the yellow-backed part of the window.  Tempo is usually set by clicking on the number labeled "beats", and setting the number of beats in the loop.

When open to the jamman memory card, or a directory in jamman format,  settings for "stop/finish," "loop/single," and the jamman rhythm style are at the bottom of the window.

consolidate

command-P (or Edit/Push to Top from the menu) will renumber the loops starting from 1. 

subtract loops ("detangle")

If there are multiple copies of a loop with different solos recorded over them,  "detangle" separates the solos from the backup (note: there must also be a loop of the backup alone).  Select a group and choose "Edit/Detangle" from the menu.  Originals get "_C" added to their name (for "composite"); the solo tracks have "_M" in the name (for "mono").

back up loops

With loops selected, choose "File/Backup selected" to make copies to another directory, preserving extra data like name and tempo.

import

choose "File/Import/wave" to bring a wave file in as a loop.

"File/Import/Everyday Looper" and "File/Import/EverydayLooper directory" are for importing files from the excellent iphone/ipad app "Everyday Looper" (www.mancingdolecules.com/everyday-looper/).  Importing is a two-step process:

From Everyday Looper, start the HTTP server and note its IP address.  Choose "File/Import/Everyday Looper" and provide that IP address to copy files onto the computer.

When that process is complete, choose "File/Import/EverydayLooper directory" to transfer the files into the loop directory.


extra features

mixer

If a loop is selected, Command-M (or Extra/Mixer from the menu) will open that loop's group.   The mixer lets you hear the loops together in different combinations.

looper (experimental)

The built-in looper starts recording audio when the record button is pushed.  After that, it records continuously, saving the previous segment each time the record button is pushed again. 

The adjust option allows the loop to be re-aligned to previous loops (or, for the first loop, for the recording length to be adjusted).  The double button copies the existing loops repeated, to make the recording time twice as long.

looper from group

If a loop is selected, this opens the built-in looper with that group already in it.

sequencer

With multiple loops selected, choosing Extra/Sequencer will open a window that allows a new loop to be created by stringing the existing loops together in any order.  The new audio file will show up named "sequence".

spectral

Shows a spectral view of the selected loop.

Edit Menu

Tempo Settings

Loop tempo settings are set in the yellow-backed area.  To set the tempo, click on the number marked 'beats' and choose the number. 

"Lag" allows the playback to begin elsewhere than the start of the recording.  If the recording starts and ends on beat 4, for example, the lag will rotate the beat so that playback starts at beat 1.  The audio file can be re-written to begin at beat 1 using the Edit/Unlag menu item.

Working settings

At the bottom of the application window are severa additional settings.

waves/jamman : choose whether to store backup files as a directory per loop (as the Jamman does) or as a named wave files.

writeable/locked : when locked, the loops in the current directory are read-only and their settings cannot be changed.

group : whether to change all tempo settings in a group whenever any are changed.

line: the number of measures per line in the waveform display.

stop/loop/rhythm : when the current directory is in jamman format, the jamman-specific settings for stop/finish, loop/single, and rhythm style are available.

info window: The display in the lower right shows the length of the current loop in samples and average volume in deciBels.
