Member Data Documentation

m_clip

AutomationClip* lmms::AutomationNode::m_clip

private

Clip that this node belongs to.

m_inTangent

float lmms::AutomationNode::m_inTangent

private

Slope at each point for calculating spline.

We might have discrete jumps between curves, so we possibly have two different tangents for each side of the curve. If m_inValue and m_outValue are equal, m_inTangent and m_outTangent are equal too.

m_inValue

float lmms::AutomationNode::m_inValue

private

m_lockedTangents

bool lmms::AutomationNode::m_lockedTangents

private

If the tangents were edited manually, this will be true. That way the tangents from this node will not be recalculated. It's set back to false if the tangents are reset.

m_outTangent

float lmms::AutomationNode::m_outTangent

private

Slope at each point for calculating spline.

We might have discrete jumps between curves, so we possibly have two different tangents for each side of the curve. If m_inValue and m_outValue are equal, m_inTangent and m_outTangent are equal too.

m_outValue

float lmms::AutomationNode::m_outValue

private

m_pos

int lmms::AutomationNode::m_pos

private

Time position of this node (matches the timeMap key).
