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
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.
can be used for
- mixer, for listening to existing loops
- built-in looper, for adding
tracks through the computer
- sequencer, for creating a new loop by
stringing together existing loops
- spectral view
name or rename
Select a loop and press 'return'
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.
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
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.
choose "File/Import/wave" to
bring a wave file in as a loop.
for importing files from the excellent iphone/ipad app "Everyday Looper"
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
When that process is complete, choose "File/Import/EverydayLooper
directory" to transfer the files into the loop directory.
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.
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
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.
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
Shows a spectral view of the selected loop.
- Edit/Push to Top : renumber loops in order from 1.
- Edit/Add Blank Track : add a silent trak whose length and tempo
can be chosen, to record into.
- Edit/Unlag : re-write the audio file to change the starting
point. Lag is set in 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.
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.
