Alter is an effects processor for eurorack format. There are two versions which are visually identical except the name "Alter 1" and "Alter 2". This is Alter 1. Internally each has an entirely different set of effects from the other. Each features 7 different DSP effects meticulously designed over the course of a year.




- controls for mix, X, Y and filter as well as clock.

- all effects have a variation of a filter which may change effect to effect.

- X and Y control various rates, feedback and time over the different effects (note that some of the images shows a prototype whcih says "rate" under two of the pots. The faceplate has been changed to X and Y).

- clock control adjusts the rate which controls the DSP which can drastically change the effect. In doing so it does slightly lower the quality of the output signal but the results are fantastic. This clock is not for synchronization.

- mix, X, Y and filter all have CV control inputs.

- Each control level or cv input is visualized on the control panel.

- stereo inputs with separate level/gain control for right and left channels

These levels can also act as mute as it can take the signal to 0. They can also add gain to a quiet signal.

- peak level indicator for clipping levels at the input

- mono input is made stereo within dsp and outputs to both left and right channels

- stereo outputs for right and left channels



The effect is selected by the hexagonal touch pad.

The effects for Alter 1 are as follows:

1; long delay

2; tight, notated granular delay

3; huge plate reverb

4; shimmering reverb

5; distortion and multi-filter

6; pitch delay

7; stutter glitch
