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.

Pedals

This controller was created as a small, light and portable solution for hands free manipulation of software. It was initially intended to control the recording and playback of sampled material but can also be used for various triggering functions. In addition to this, the controller has two 1/4" TRS jacks for external expression pedals/continuous control and LEDs to provide visual feedback of looper state (record, overdub, stopped) and bank select. Cardboard was used to create a temporary enclosure whilst building the circuit, providing a  sense of the overall size and ensuring that everything would fit inside. This will be replaced with a stronger material in the future.

Boweable Encoder Patch

This patch explores various possibilities for mapping the boweable encoder and provides values for acceleration, direction and duration of movements. In particular, the duration of movement was used to trigger events using the metro object. This was combined with the direction of movement to trigger different envelope shapes.
