Jambé 2 Beta Upgrade Guide

About Jambé 2

From the begining, we conceived Jambé as a new type of performance instrument. Version 2 of the Jambé app takes that to the next level with support for multiple Jambés, MIDI – including MPE, and much more.

Before you upgrade

If you're a Jambé 1.0 user, be sure to backup your 1.0 kits, especially any you've created or modified.


We've made changes to the kit file format in Jambé 2. When an older kit is opened, it's automatically updated to the newer format. In most cases, this is what you want. Your older kit simply works in the newer software. However, the updated kit won't work with Jambé 1.0 software. Making a backup of anything you care about is a good idea.

You can find updated versions of our existing kits as well as kits that use the new Jambé 2 features - here We'll add new kits as they become available.


if you haven't modified an older kit, you're better of downloading the updated copy from the new site.


We use Apple's Testflight application to distribute the beta releases of Jambé 2. You can learn more here: TestFlight

New Features

More Pads and Triggering Options

Support for 30 Pads

In Jambé, much of the app is constructed around the idea of a pad and what happens when the pressure on that pad changes. The Jambé 1.0 app supporrted 10 pads with a one to one mapping between those pads and a connected Jambé device. The Jambé 2 app increases the number of supported pads to 30. The 30 pads are represented in the app as three virtual Jambés. Jambé devices connected to the app are mapped to the virtual Jambés.

Up to 3 phystical Jambés on one iPad

Up to 3 Jambé devices can be connected to the Jambé 2 app on a single iPad. To take advantage of this, you'll need to use a powered USB hub. Connect the hub to the your iPad using an appropriate adapter. This is typically the adapter you use to connect your Jambé to the iPad. Then plug the Jambé devices directly into the hub. We've also tested connecting a USB audio/MIDI interface into the hub as well. If you don't have 3 physical Jambés, don't worry. You can control how your Jambé is mapped to the virtual pads. We're also always happy to sell you another Jambé!

MIDI and MPE Input

In addition to multiple Jambés, you can use MIDI devices to trigger the virtual pads. Note that we rquire at least one Jambé device to be connected to the app for MIDI input to be enabled. THe Jambé 2 app is also compatible with MPE (MIDI Polyphonic Expression) as well as standard MIDI. When using MPE, the Z-axis maps maps to pressure on a Jambé pad. The X-axis and Y-axis can be used as modulation sources.


In the Jambé 1.0 app, the only thing that could haappen when a pad was struck was triggering one of Jambé's internal instruments. In Jambé 2, we introduce the idea of actions. In addition to "Sampler Instrument Actions", we add "Delay Actions," and "MIDI Actions."

To support this, you'll notice through out the Jambé app, Actions replaces the Instruments in the top selector and the Library views.

Multiple Actions per Pad

In Jambé 2, multiple actions an be attached to each pad. The actions are triggered in the order they appear in the Kit's "Pad Info" view.

Sampler Instrument Actions

The "Sampler Instruments" section contains what were previously called "Instruments" in Jambé 1.0.


Each of the Sampler Instruments on a Pad consume a voice when triggered. The more Sampler Instruments you add to a pad, the more voices are used when that pad is struck. On slower iPads, this can lead you to quickly run out of voices.

Delay Actions

Delay actions allow you to insert a delay between two other actions on a pad.

MIDI Actions

MIDI Actions allow you to send MIDI commands to connected devices. MIDI Actions are compreised of on or more MIDI commands. This allows you to send complex sets of MIDI commands when a pad is triggered. Support for MPE, MIDI Show Control, and modulation from Jambé sources are supported. We believe we have that Jambé 2 provices the most extensive MIDI inplementation of any performance instrument.

Play View Improvements.

Jambé 2 ads several improvements that make it easier to manage kits.


Tags allow you to easily add information about a kit that makes it easy to filter and sort the Play view. Tags are stored in the Jambé 2 kit file, so they travel with the kit.

Tag Expressions

Tag expressions allow you to filter the Play view, showing only kits that have particular tags. Or don't have particular tags. Tag Expressions provide a way to group kits together into Banks.

Kit Sorting

While Tag Expressions allow you to choose what kits get displayed, there are new sorting functions that allow you to choose which order the kits are displayed in.

MIDI Bank Select

Jambé 2 supports MIDI Bank Select messages to move between the banks defined by Tag Expressions.

MIDI Program Change

Jambé 2 supports MIDI Program Change messages to move between kits in the current bank or Tag Expression.

Intverval or Relative Mode

Interval Mode is a new way of using Jambé. We're still exploring and refining it, but it offers some very interesting performance possibilities.

Sampler Instruments now have a scale parameter. You can choose from a number of built-in scales. In the Kit editor, you can specify the scale degree for that pad when it triggers the Sampler Instrument action. Place the same Sampler Instrument on multiple pads and it's easy to have one pad play the first note in the scale, another play the second, and yet another play the fifth. Change the Sampler Instrument's scale and pitches triggered by the pads change.

There's more. In the Kit Editor, you can specify that the pad's interval gets added to the last interval played. For example, setting the pad's interval to "1 semitone" and clicking "Add to Last" will cause the Sampler Instrument to increase one step through the scale on each hit. Set the pad's interval to "-1 semitone" and hits will step down through the scale.


There are no limits on the pitch shifting up or down. It's easy to quickly get into the inaudible range. When designing a kit using interval mode, it's a good idea to have at least one pad with an interval of "0 semitones" and "Add to last" unchecked. You can use this pad as a reset.
