| - | ======Hihat Openness Control Feature - Design Document====== | ||
| - | //This document does not describe a feature in DrumGizmo, but is rather a collection of ideas for how a future feature could be implemented.// | ||
| - | =====Concept===== | ||
| - | Midi drumkits can sometimes send midi events when the hihat pedal position changes. | ||
| - | |||
| - | No standard way exists for how this is done, but two major ways have been observed: | ||
| - | - When the hihat is hit, different note-on events are sent depending on openness, and a specific note for when the hihat is completely closed. | ||
| - | - When the hihat is hit, the same note-on event is sent, but when the openness changes a midi CC event is sent with the openness parameter. | ||
| - | |||
| - | Somehow map these events to control DrumGizmo sample engine in the most natural way possible. | ||
| - | |||
| - | =====Requirements===== | ||
| - | Since no one way exists, the feature should be configurable by the users to make it work with whatever kit they have available. | ||
| - | |||
| - | It should be possible to also use this feature with a DAW, without a drumkit, using " | ||
| - | |||
| - | =====Idea 1: Sample Control===== | ||
| - | Extend the features of the sample generation to include openness parameter, similar to the position parameter of the snaredrum. | ||
| - | When a hihat note is played, select the appropriate one from the set. | ||
| - | |||
| - | The openness must be mappable though the midimap file, which needs extending with a new syntax for mapping either notes to " | ||
| - | |||
| - | If a hihat note is being played and the openness changes the following should happen: | ||
| - | - The percentage of the current play position is calculated (eg. 40% in) | ||
| - | - A new sample is selected from the new " | ||
| - | - A fade-out is activated in the current sample. | ||
| - | - The new sample starts playing also 40% into its duration, with a similar fade-in resulting in a cross-fade between the two. | ||
