iJammer - Wireless MIDI Jammer-Style Control Surface

iOS iPad

iJammer is a WiFi-based wireless MIDI "Jammer-style" control surface for the iPad

The scale patterns are very intuitive, and the built-in note guide makes it easy to learn to play!

The layout has independent mirror-image keyboards for the left and right hands.

Wikipedia has a great article about this style keyboard, just search for "Jammer Keyboard".

iJammer supports two independent wireless MIDI channels and has a 9-octave range.

To play, simply touch the buttons. Buttons light up when playing

Multiple buttons may be touched at the same time to play chords.

You can slide between the buttons.

Touch the '?' icon to show the note names for each button.

Touch the MIDI connector icon to show the MIDI parameter controls.

iJammer doesn't produce any sound on it own, it is designed for controlling hardware or software VST-style MIDI synthesizers via a WiFi connection to a Windows or Mac OS X based computer.

Multiple iPads can run iJammer on the same wireless network, each sending messages on its own set of MIDI channels to the hardware or software synthesizer.

To play, just touch the buttons. Multiple buttons may be touched at the same time to create chords.

The two sides are mirror images of each other.

Both sides may be transposed independently.

Touch the red or blue bars at the bottom of either side to transpose down or up one octave for that side.

The display above the bars shows the current octave for each side.

Touch the "?" icon at the lower right to display the note names.

Touch the MIDI connector icon at the upper left to display the MIDI controls.

You may select the and volume, MIDI channel, attack velocity, and semitone transposition (0-11) for the two sides independently.

All MIDI settings are saved when iJammer quits and restored the next time it is run.

Touch the '!' icon at the lower left to quiet any "stuck" notes if they occur.

Rotate the iPad to portrait orientation to display the help screen.

Touch any of the green highlighted links on the help page to go directly to webpages with additional information about iJammer and Jammer-style controllers.

iJammer requires two pieces of software to do its job. The first is the iJammer app itself, running on your iPad.

The other is a small free open-source DSWiFiMIDI server application that you run on your PC or Mac before launching iJammer.

The server application receives the MIDI messages from iJammer via WiFi, and sends them along to either an external MIDI interface or a loopback MIDI driver to talk to software synthesizers running on the same computer.

Please visit the app website for information on downloading and installing the open-source DSMIDIWiFi server application for your system.

For the most reliable performance with the lowest possible latency, I highly recommend that you connect the PC or Mac to the wireless access point that will be used by the iPad via a wired ethernet cable rather than use wireless for both the computer and the iPad. The computer and wireless gateway that the iPad is connected to must be on the same network.

To get the full benefit of using iJammer, you should be familiar with the use of MIDI control surfaces, hardware and/or software VST synthesizers.

If you have any concern about the compatibility of iJammer with your own MIDI setup, I recommend first testing with one the other free DSMIDIWiFi-based apps available on the iTunes App Store before purchasing iJammer.

You may play along with tunes in your iPad's music library by starting a track using the iPad iTunes app, then launching iJammer.

Please visit the iJammmer app website for a live demonstration video.
