Sample Manipulation

This interface was created in preparation for an upcoming performance using the previously built mixer panel to manipulating sampled material. This also provided the opportunity to build and test the revised layout for the mixer channels. 

Due to time constraints, large holes were created to allow access to the buttons. This will be improved in later developments and provides the opportunity to experiment with different materials and techniques to achieve a suitable tactile response.

In particular, the small sliders used for the new mixer channels allows for fast and easily accessible control over send levels and filter parameters. This most effective when the rows of three sliders are mapped to LPF cutoff, HPF cutoff and resonance respectively, allowing bandpass and other variations to be achieved using quick and small gestures.
However, the small size of the sliders also decreases the resolution which may be desirable for controlling filter cutoff.

In addition to this, a max patch was created in order to explore various manipulations of sample playback using the 2d.wave object. The 'rows' parameter allows for basic timestretching, providing independent control of pitch and speed. However, the lack of windowing generates clicks and other artifacts.

 In particular, the use of feedback and interrelated modulation inputs were used. This also allows the analysis and audio signals from the cello to be used within this patch.
