#182 Copy and export Time Instant layer as midi

[Samuel Miller]

Please consider adding an onset detection to midi vamp plugin. Currently, the available Vamp onset detection plugins output their results as time instant layers. Onset detection gives more accurate results for percussion hits than the available note transcription plugins. Following Melodyne as an example, it outputs its percussion detection algorithm as one pitch, 440hz, which in midi is 69. There could be two options for midi output: hits (attack points) and sustained, where the duration of each note is extended to the next hit. In addition, it would be a handy feature to be able to copy and export time instant layers as midi annotation. Currently, I manually edit time instant svl in a text editor, such as Atom, to convert it to a midi svl to import it as a midi annotation layer. I then may export the same midi layer as midi for Musescore for notation. Thanks again, Sam

The hit or sustained output of converting time instants to midi layer could be based upon what plot type is selected on the time instant layer: instants or segmentation. This would automate the output option process and avoid having to add or modify a dialogue box. Also, to be consisent, the same feature could be added to midi layers, allowing them to be "converted" into time instants, either by copying or exporting.
