One of the most often requested features for the BopPad is the ability to send out multiple notes per quadrant. In a previous article we discussed setting this up in Ableton Live, but what if you don’t have Ableton Live? I’ve coded up a Max application (mac only for the time being) that can act as a middle man between the BopPad and music software. This app will allow you to send out multiple notes per quadrant to any DAW, synth or sampler on your Mac OS system. You can download the app and project here: https://www.keithmcmillen.com/projects/boppad-zones/
The application is not very complicated, but I thought that going over the basic operation would be helpful to get started. Upon opening the application you’ll be presented with the UI. The first thing to do is get the MIDI in and out configured properly:
You’ll want to set the MIDI input to be taken from the BopPad, and set the MIDI output to one of the virtual MIDI ports provide by the application, From BopPad_Zones or From Max, if using the Max patch, and not the standalone.
Next, you might want to select the factory ‘Sticks’ preset using the BopPad Editor, or by using the ‘Preset’ parameter (if you have the Sticks preset loaded onto your BopPad, it is factory preset 3). This is not necessary, but will save some setup time as the application comes preconfigured to work with that particular preset. Each of the four squares can be setup to take MIDI from one of the quadrants, based on the Channel parameter. Once the data is in the application, the device will look for the radius CC defined by the CC Number parameter, and then spit out notes according to the rest of the settings: Curve, Base Note, Divisions, Scale, and Root. The Curve defines how the radius is translated into zones, there are four options: Linear, Exponential, Cubic, and Sine. Experiment with the different values to find the curve that feels best for you. The Base Note is the MIDI note assigned to the inner most part of the quadrant. Divisions is how many different zones the quadrant will be divided into. And the Scale and the Root parameters can confine the MIDI notes to a particular musical scale. The Output box will show you what note the application is sending out. The device comes preconfigured to play a C Major scale starting on C1 (note number 36) from all the quadrants.
You can set this application up to do a variety of interesting things, from playing multiple drum samples from each quadrant, or play melodic percussion over multiple octaves, or setup some crazy synth with four distinct voices that are always in key with each other. We are providing a standalone application as well as the Max patch if you’d like to modify the insides. Happy Bopping!
