(Addresses #1421) **Behaviour description:** * Toggle step-recording mode using the dedicated icon. * This mode is mutually exclusive with other recoding modes (record/record accompany). * Step-Recording while song is playing is allowed (and fun! :) ). * When start recording, the start recording-position will be set where the timeline curser points (quantized backwards using PianoRoll's current quantization). If step-recording is started while the pattern is playing the start recording-position is set to the beginning of the pattern. * Step length is determined by the Piano Roll's current note-length (can be changed dynamically during step-recording). * The record-position can be moved forward/backward using the right/left keys. * When notes are pressed on keyboard/midi-device, they will be added temporarily ("recorded") with a length of a step. while still pressed, user can adjust the length by steps resolution using the arrow keys (e.g. moving right once will make the note's length 2-steps, another right press will make the length 3-steps etc.). * When all pressed-keys are released, the actual recording happen and the notes are added. * If the user press multiple notes, and release some of them for some time which indicates it is intentional i.e. he didn't want to do a full release to record the step but rather just change what will be recorded (I set the "intentional release threshold" to 70 milliseconds) - these note will be removed from current step-recording. e.g. * Added notes are not quantized, making the addition simpler and WYSIWYG * Similiarly to adding notes using mouse clicks, an undo-checkpoint is added per added step and not for the whole recording as in other record modes.
