Fix some problems from the plugin tester: zero sample rate with fixed sample type outputs; mismatching parameter id ("spectralshape" in Chordino, "s" in NNLSBase -- changing this in Chordino won't break anything as it would never have worked under that name anyway); some NaN values

NNLS Chroma 0.2 -- Release Notes

General Description:

A Vamp plugin library for harmony and chord extraction with some features aimed at amateur musicians, and some at music information retrieval researchers.
It contains the Chordino, NNLS Chroma and Tuning plugins.
For more information see README or http://isophonics.net/nnls-chroma

New features: 

Chordino:
* The new MIDI note output of the estimated chords allows, for example, instant playback of chord notes in Sonic Visualiser.
* new parameter "boost N": allows better recognition of the "no chord" label N (default setting is 0.1, previous Chordino version had no boost, i.e. 0.0).

NNLS Chroma:
* new output "Consonance Estimate". Experimental attempt to capture the tonal consonance in at a given time. Based on the convolution of a simple consonance profile with the semitone spectrum.

Bug fixes:

* Default chord dictionary loads when no chord.dict file found in Vamp path.
* Corrected parameter range for spectral rollon parameter (Chordino).
* Semitone Spectrum has values at zero energy frames (NNLS Chroma).
* Crash with non-standard input resolved (now amplitude-limited).
* minor internal fixes.
