PA1 Dynamic Plate Reverb is an FX plug-in that uses a pure numerical model of a plate, with no impulse responses or delay networks. The dynamic control of physical parameters gives unique and creative reverberation.

Adjustable plate

Vary the plate dimensions up to 3m x 2m, adjust the tension, and choose from 6 different materials such as Gold and Titanium.

Frequency-dependent decay

Frequency-dependent T60 decay times over 8 octave bands, from 0.3 to 10 seconds.

Variable pickups

Change the left and right channel pickup positions across the plate.

Pure Numerical Modelling

We start from a mathematical description, the Kirchhoff plate equation, that gives the displacement in terms of size, thickness, and tension, as well as the properties of the chosen material (Young's modulus, density, and Poisson's ratio). Using this description we calculate 6,000 modes of vibration for the system to give a dense and rich reverberant quality. From there we perform a real-time integration to compute the displacement of the plate, with the decay times across the 8 octave bands of the modes.

PA1 Dynamic Plate Reverb will be released 30th March
