iJammer - Jammer-Style CoreMIDI Control Surface

By Michael Eskin

Open iTunes to buy and download apps.

Description

iJammer is a "Jammer-style" CoreMIDI control surface for the iPad

iJammer doesn't produce any sound on it own, it is designed for playing hardware and software VST-style MIDI synthesizers via a CoreMIDI compatible interface connected to the dock connector or virtual MIDI instruments like IK Multimedia SampleTank® for iOS running on your iPad.

Please visit the app support website to see some amazing live demo videos and for the settings you will need to enable in the synth app you are using to have it work with the control surface.

Reviewer "M80 M80" in France, please check the app's website FAQ for a fix to your "stuck at the help screen" issue. It's an issue Apple created unfortunately with the 6.0.1 update, not a bug with the app, and is very easily fixed.

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 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.

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.

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

Q: I just updated my iPad to iOS 6.0.1 and I'm stuck at the help screen!

A: Apple messed up the restoration of the Mute/Orientation switch state after the update. Please visit http://www.tradlessons.com/ios601mutefix.html or the app's website for a simple fix.

Here's the settings changes required for two popular synth apps:

IK Multimedia SampleTank:

- In Settings (touch the gear icon), enable "Background Audio"

Sonosaurus ThumbJam:

- In "Prefs", under "MIDI Control", in "MIDI General Options" enable "Use CoreMIDI" and "Active in Background"

Other CoreMIDI compatible synth apps will have similar settings.


What's New in Version 2.0

iJammer now only supports CoreMIDI-compatible interfaces or virtual MIDI instruments like IK Multimedia SampleTank® for iOS running on your iPad.

Note: This version no longer supports the pre-CoreMIDI DSMIDI-WiFi server based wireless MIDI any more. If you're want to keep using DSMIDI-WiFi, please don't update to this new version. (But you really should, the CoreMIDI version is so much more useful in so many ways and works with so many more devices and software synths for iOS...)

This version also fixes a major touch position bug on Retina display equipped iPads.
