Alisa VCF | Tre Modular

Tre Modular – Alisa VCF is a transistor ladder filter based on the filter section of the Alisa 1387 and Alisa 1377. Alisa VCF can produce a distinctive, gritty sound and is excellent for adding that nastiness to your patch.

This filter is mostly based on Alisa 1387 but we have added some parts from 1377. Most notably distortion stage from the Alisa 1377 filter. You can choose to route the output and/or resonance through this distortion stage with the press of DIST and RES buttons. This works in all combinations, giving you four unique-sounding filter modes.

Here is a jam showing off this module.

Distortion:

Here you can see how the output of the filter looks when it is not routed trough distortion stage.

Here you can see how the same signal looks when it is routed trough distortion stage.

Resonance:

Here you can see how the resonance looks when it is not routed trough distortion stage.

Here you can see how the resonance looks when it is routed trough distortion stage.

Here is a lengthy video with filter sweeps with every waveform found on Alisa VCO.
