Erae Autoharp webapp Instructions

This Webapp processes MIDI events from an Erae 2 and uses it to simulate an autoharp using MIDI sound sources.

This is the ".erproj" Erae 2 project that goes with this webapp:
Autoharps Project:
The layouts in that project are:
  1. Autoharp 30 button layout
  2. Autoharp 21 button Oscar Schmidt layout
Or you can get the ".emk" layouts individually:
There are a number of sets of chords that correspond to each layout. The Schmidt layout has quite a few, including the Prizim layout, which requires pressing two chord buttons at a time.

MIDI output

Connect this webapp's MIDI Input device to "Embodme: Erae 2 MIDI".
This webapp sends notes to a MIDI synthesizer, do that by choosing a MIDI Output device. Make sure that the output MIDI device or virtual device is only listening to a generic port like "IAC Bus 1" and NOT to signals from the Erae 2 directly!
After setting up the devices, load the layout you want on the Erae. The large X-Y controller area works like an autoharp's strings, except it can only pick up one touch at a time, so pinching and a few other techniques don't work. Pressure translates to velocity!
This webapp has a few other parameters:
