Positive Grid, maker of mobile guitar apps BIAS and JamUp, today announced the release of the BT-2 and BT-4, two fully-programmable Bluetooth MIDI foot controllers. These two-button and four-button controllers boast I/O features for iPhone, iPad and Mac, allowing hands-free control over iOS and Mac apps.
Users of MIDI-supported apps will be able to switch any parameter without connecting cables — change stomp box effects in real time, raise and lower volume, turn sheet music on a screen.
How it works
Positive Grid’s BT-2 and BT-4 foot controllers are MIDI foot controllers based on Bluetooth 4.0 technology. Users can assign MIDI messages to the controllers by using an iOS app that edits the assignments. Each MIDI-compatible iOS app supports a standard communication protocol that enables them to be controlled wirelessly. Both BT pedals can be expanded by adding an expression pedal or footswitch using a 1/4-inch phone-type jack, allowing musicians to control rotary functions like whammy and wah effects, keyboard sustain, amp gain and volume, EQ and more.

Like ik’s Bluetooth pedal, but better.
About positive grid’s bt-4 bluetooth midi controller , really wanted to get hold of this product but it seems like it’s taking them too long to have it released on the market , really frustrating . I believe this product is better than that of ik multimedia’s irig blueboard , with the metal chassis construction and line out , really way better i should say .
I feel your pain! I emailed them about the board myself over a year ago. Tired of waiting! The board needs a expression pedal to really sell at this point the board looks dated and it’s not even out yet…
