Cosmic Drift is an experimental stereo memory processor with 30 seconds of memory and four drifting memory voices. HOLD freezes the memory state while algorithms, movement, and degradation remain fully playable and live-controllable.

Description
Cosmic Drift
Cosmic Drift is inspired by the SOMA Cosmos and the Chase Bliss Habit Delay, but it is not a copy; rather, it is an independent interpretation of these ideas. The effect is an experimental stereo memory processor with up to 30 seconds of stereo memory, in which four virtual looper/memory voices independently move through the stored audio material. The voices create continuous, organic repetitions that slowly move through time and the stereo field, creating a living, constantly evolving soundscape. Different algorithms determine how the four memory voices interact with each other and which areas of the memory they explore. This allows old sonic events to suddenly come back to the foreground while others slowly disappear or overlap with new repetitions. The various presets range from subtle, organic movement to heavily processed and complex memory structures.
The defining feature of Cosmic Drift is HOLD: A short footswitch press completely stops new input signals from being written into the memory, while the already running memory loops continue indefinitely. They do not stop, slow down, or fade out—while all three knobs remain active, allowing the held memory to continue being altered and manipulated. For HOLD to be used effectively, the 30-second memory should first be filled as completely as possible, similar to the Chase Bliss Habit. Only when enough musical material is present in the memory can HOLD capture a complex, layered moment and then allow it to be played as an instrument in its own right. This transforms a simple delay into a playable, persistent memory state that continues to evolve after being frozen, without recording any new audio material.
Knob 1 – Algorithm
Knob 1 selects the different memory algorithms, which determine the movement and interaction of the four virtual voices. The algorithms range from simple Drift to Orbit, Deep Memory, Cross, and Reverse behaviors, all the way to complex, cosmic-sounding combinations. At the fully clockwise position, a Random Cosmic Performance Mode is activated: every four bars, a new algorithm is selected, with a 50% probability that one of the memory voices will also play in reverse. The loops that are already running remain continuously active and are never restarted.
Knob 2 – Memory Movement / Time
Knob 2 determines the temporal organization of the memory voices and which areas of the 30-second memory are preferentially accessed. The 24 presets range from Short/Medium/Long Echo, Deep Memory, Spread, Drift, and Orbit to Scatter, Phase, Memory Walk, and Cosmic Time. The presets alter the temporal relationships and positions of the voices, not their normal playback speed, avoiding unwanted tape-style slowdown. At the fully counterclockwise position, the complete preset sequence from 1 to 24 automatically cycles every two bars. At the fully clockwise position, a new preset is randomly selected every two bars.
Knob 3 – Memory Character
Knob 3 changes the tonal character and aging of the memory, ranging from completely clean to extremely degraded. The 20 presets range from Pure, Warm Tape, and Worn Tape to Drift, Dropout, Dark Memory, and Aged, all the way to Corrupted Tape, Memory Melt, and Total Decay. Tape saturation, compression, filtering, wow & flutter, stereo drift, dropouts, and other degradation processes can be combined. At the fully clockwise position, the Random Auto Character Mode is activated, selecting a new sound-character preset every two bars.
Footswitch
A short press activates or deactivates HOLD. This exclusively stops new input signals from being written into the memory—the existing loops continue playing without interruption, without any change in playback speed, and without fading out. For the best results, the 30-second memory should first be filled as completely as possible before activating HOLD, so that many different temporal layers and sonic events are present simultaneously when the memory is frozen. Multiple rapid short presses activate Tap Tempo with a minimum tempo of 40 BPM, while a long press clears the entire memory. The blue LED remains continuously lit while HOLD is active, and the red LED pulses on every quarter note of the current tempo.
