3.1.4. Refused and warned connections

A cable carries a signal between compatible sockets. Check the signal kind, unit and range before choosing its destination.

3.1.4.1. Refused connections

A refused drag cannot create a cable to the target socket. Dragging an LFO control signal onto Filter Audio In gives Incompatible socket feedback: the destination needs audio, while the source produces a control signal.

An LFO Cannot Feed An Audio Input.

1. Hold the drag over the target socket and read the feedback.
2. Compare the source and target signal kinds in Help.
3. Follow the matching case below before trying the cable again.

Result: the cause of the refusal or warning is visible before you change the routing.

Throughline gives a reason when it refuses a drag. Common reasons:

• Incompatible socket: the two kinds cannot connect, for example an audio output into a MIDI input.
• Choose an input socket as the target: both ends are outputs. Drag from an output to an input.
• Both sockets belong to the same node.
• Map Range is locked to …, but this target expects …: a Map Range that already drives one kind of target cannot drive a different one.
• Polyphony Zones don't take audio input: a Zone accepts notes, not audio. See Polyphony.
• … is controlled by a Macro: remove the Macro binding first.

3.1.4.2. Warned connections

A drag that is allowed can still show a warning. It means the source can reach the destination, but you need to check its numerical range. A bipolar LFO sent directly to Oscillator Pitch keeps its raw values instead of becoming a musical pitch sweep.

A Warned Raw Pitch Drag.

Compare the source range with the destination’s unit in Help before accepting the drag. For a deliberate frequency sweep, use Map Range to choose the destination range explicitly. See Control signals and logic.
