Hello osculator-wiimote users,
I've been working on a wiimote musical composition, making use of 3 general wiimote gestures:
1) Striking - like striking a drum - accomplished using the osculator "MIDI Note" feature, attached to the accel param.
2) Swinging - like waving a wand - accomplished using the osculator "MIDI Note w/ Params", triggered by a button, and using "Note Params" to set musical-pitch and velocity based on wiimote-pitch and roll. Note: this is enhanced by enabling in osculator Parameters/IO/MIDI Notes w Params settings/CHECK ON Emulate Pitch Bend Wheel.
3) Discrete Positions [the focus of this post] - like placing the wiimote in a specific spacial area (such as into different mailbox cubbies) to trigger different pitches - I accomplished this by combining osculator and midipipe. Osculator sends out MIDI CC (controller) signals associated with a parameter such as wiimote-pitch, and a trigger event using MIDI Note. Osculater sends these MIDI signals to a shared MIDI bus, such as IAC Bus 1. Midipipe then takes input from that MIDI bus, and applies an applescript trigger shown below, and then sends the new output do a different MIDI buss (ex: IAC Bus 2). This script is effectively similar to the osculator MIDI Note w/ Params, except that I am able to control which specific notes are returned -- in my current case, I'm using the wiimote-pitch parameter, to define areas of an arc that correspond with notes from a pentatonic minor scale [Cm: C, Eb, F, G, Bb, C] (vs. returning several chromatic notes [C, Db, D, Eb, E, F]).
Hopefully someone may find this useful.
best,
