Positive Grid Intros Bluetooth MIDI Foot Controllers w iOS Features

Positive_Grid_BT-41Positive 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_BT-4_anglePositive 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.

  1. 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 .

  2. 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…
