A wiimote attached to the leg of the user measures their walking speed, when this reaches a certain value (currently a MIDI CC value of 30 but this needs to be adjusted) the MIDI channel is switched from 1 to 2 to control another sampler on MIDI channel 2 (it may be better to just add 12 to the MIDI value and store the running samples in the same sampler instance in Ableton).
This is a good improvement on the previous patch although sticking a wiimote in a sock is hardly the best way to do it.
Footstep samples for specific surfaces at different walking/ running speeds now need to be found to demonstrate this properly.
Still need to find a way to adjust velocity effectively (does a hard footstep have more high or low frequency content than a soft footstep? if so adjustment of high or low pass filters relative to the velocity info from the balance board could be worth experimenting with).
PD patch (new section highlighted blue).
