Membrane

The Membrane is a drumhead, for toms and timpani, or a snare drum with its snares on. Like every Resonator, it takes Springs, Exciters, and Mics anywhere on its surface, and its pitch follows the played note. Its contact points are placed across the round head with Contact: U and Contact: V, each running from 0 at one edge to 1 at the other, with 0.5 and 0.5 at the center.

Its Frequency, decay, Material, Tension, Mode EQ, and other shared properties are documented on the Resonator page. Tension is what gives a hard-hit drum its pitch drop.

Membrane Properties#

Strainer#

The Strainer holds snares under the Membrane, across the middle of the head, that it rattles against.

• Strainer: Snares under the Membrane that it rattles against: Stops presses fixed points against it, and Wires presses loose wires that bounce on their own. Off has no snares. The settings below appear while the Strainer is Stops or Wires.
• Snares: How far the snares press into the Membrane at rest, in strike swings; below 0 they hang that far clear of it.
• Count: How many points along the strainer touch the Membrane; fewer cost less CPU.
• Width: How much of the Membrane's diameter the strainer spans.
• Hardness: The snares' stiffness, as the frequency the Membrane rings at while pressed against them.

The following settings appear only while the Strainer is Wires:

• Snare Tone: The mass of each wire.
• Snare Tension: The stiffness of each wire's strand, as the frequency the wire rings at on it.
• Level: How loud the wires' own motion is in the Mics on the Membrane.
