Rasselbock is a re-sampler with 7 built-in effects and 5 separate channel outputs. Route effect pedals through the device and trigger them in real-time by drawing blocks onto the sequencing grid. Perfect for subtle pitch changes, dramatic sound transformations, or complete track restructuring.
7 built-in effects with real-time sequencing
5 separate channel outputs
Block-based effect triggering
Reorderable processing chain
Controls
Pattern
Like drum machines and other devices with internal sequencers, Rasselbock has 4 pattern banks (A, B, C, D) with each bank containing 8 patterns and an edit range of 64 steps.
Pattern
Control
Description
Length
Pattern length in steps (1 to 64 steps). One step is always 1/64th of a semibreve long
Plus / Minus
Increases or decreases sequence length. Hold Shift to double or half steps (2→4, 16→32, etc.)
Page
Navigate through 64-step sequences using the same 16 buttons (reuses buttons for different parts)
Snapping grid
Defines block placement grid (1/16, 1/8, 1/4). Hold mouse and drag to resize blocks
Pattern / Bank
4 banks (A–D) with 8 patterns each (total of 32 presets). Pattern index (0 to 31) determines which pattern is currently selected
Clear
Deletes the currently selected pattern
On/Off
Activates or bypasses the device. When off, audio signals bypass the effects and go directly to the main output
Effects
The 7 built-in effects can be added to the sequence by drawing blocks onto the sequence grid. Effects can be dragged to new positions in the list. The highest effect is applied first, then the second effect, and so on. This creates a processing chain where effects build upon each other.
Each effect has individual parameter controls. Shuffle and Reverse have minimal parameters (Shuffle has interval index, Reverse has none)
Mute / Solo
Mute individual effects or play them alone
Channels
The 5 individual outputs are triggered only when blocks are drawn onto their channel in the grid. This lets you decide exactly when your arrangement is routed through separate outputs, which is useful for processing only parts of your track with specific effects or effect chains.
Channels
Control
Description
Sequencing grid
Draw blocks to open output channels (e.g., blocks on channels 1&2 = signal through outputs 1&2)
Level
Output volume for each channel (0 to 100%). Equivalent to a dB range of -∞ to 0 dB
Balance
Stereo panning for each channel (-100 to 100). -100 = fully left, 0 = centered, 100 = fully right
Dry/Wet
Mix between dry (original) and wet (effected) signal (0 to 100%). 0% = no effects (dry), 100% = fully effected (wet)
The 7 built-in effects can be added to the sequence by drawing blocks onto the sequence grid in the same way you trigger output channels. What’s different is that effects can be dragged to new positions in the list. The highest effect is applied first, then the second effect, and so on. All effects except Shuffle and Reverse have their own parameter controls. This makes Rasselbock extremely powerful since there are countless effect combinations possible.
Shuffle
The Shuffle effect randomizes the signal by writing incoming signals to a delay line and playing them back in segments at random positions. It’s not completely random since adding the same sized block to the same position creates the same effect. This differs from shuffle functions on drum machines. It’s specifically for signal randomization.
Shuffle
Control
Description
Interval Index
Duration of the interval used for quantization of random positions (1 to 8). Controls the timing grid for shuffle segments
Mute / Solo
Mute individual effects or play them alone
Speed
Slows down the sample and lowers pitch by changing the signal’s playback speed. The speed ratio determines how fast or slow the audio plays relative to the original.
Speed
Control
Description
Speed Ratio Index
Speed ratio as a fraction of the original speed (0 to 16). Lower values slow down the audio, higher values speed it up
Mute / Solo
Mute individual effects or play them alone
Stop
Abruptly stops the sample or instrument. Can optionally include a spinback effect that creates a pitch-down effect before stopping.
Stop
Control
Description
Duration Index
Duration of the stop effect (1 to 8). Controls how long the stop lasts
Spinback
Enables or disables spinback effect. When enabled, creates a pitch-down effect before stopping
Mute / Solo
Mute individual effects or play them alone
Gate
Turns the signal on/off rhythmically. Mimics the Gate effect pedal but is automatically synced to the rhythm of the input signal. The gate effect “gates” the audio (turns it on and off) in intervals defined by the interval duration.
Gate
Control
Description
Interval Duration
Interval duration options:
1: 1/64 bars
2: 1/32 bars
3: 1/16 bars
4: 1/8 bars
5: 1/4 bars
6: 1/2 bars
7: 1/1 bars
8: invalid
Duration Factor
The percentage within the interval during which the audio is turned on (0 to 100%)
Mute / Solo
Mute individual effects or play them alone
Stutter
Repeats a small audio segment (glitch-style). Takes whatever sound is at the start of the block and repeats it until the end of the block.
Stutter
Control
Description
Interval Duration Index
Duration of the interval during which the signal is passed through (1 to 8). Controls the timing of stutter repetitions
Duration Factor
Out of the interval duration, how long the audio is audible for every interval (0 to 100%). Controls the on/off ratio within each stutter cycle
Mute / Solo
Mute individual effects or play them alone
Scratch
Simulates DJ-style back-and-forth movement. Simulates a turntable style scratch. The length is determined by the length of the block drawn onto the sequencing grid. The effect writes the sample to a delay line and plays it back at a rate controlled by an oscillator.
Scratch
Control
Description
Rate Bar
The rate of the oscillator controlling the playback speed, and the length of the sample that's written to the delay line (1 to 8). The effect will repeat the audio after this duration has passed
Stretch
Stretch factor affecting the scratch playback (0 to 100%). Controls the time-stretching behavior
Tone
Tone adjustment for the scratch effect (0 to 100%). Affects the frequency response
Curve
Modulation curve type:
Sine: Sine wave modulation
Triangle: Triangle wave modulation
Sawtooth: Sawtooth wave modulation
Linear: Linear modulation
Mute / Solo
Mute individual effects or play them alone
Reverse
Plays the second half of the block in reverse. Only the second half of the block is reversed because the Rasselbock needs the first half to record the sound into its internal buffer before playing it back in reverse.
Reverse
Control
Description
Mute / Solo
Mute individual effects or play them alone
Example: Enhance a drum loop
Enhance a drum loop with rhythmic effects using Rasselbock’s step sequencer and built-in effects.
Load a drum loop into an Audio Track.
Add Rasselbock as an effect after the Audio Track.
Create a 16-step pattern by setting the length to 16.
Assign effects to different channels:
Channel 1: Gate effect
Channel 2: Stutter effect
Channel 3: Reverse effect
Place blocks on the sequencing grid:
Draw Gate blocks on steps 1–4
Draw Stutter blocks on steps 5–8
Draw Reverse blocks on steps 9–12
Fine-tune effects using their individual parameter controls.
Adjust Dry/Wet mix and use Mute/Solo buttons for testing different combinations.
Practical Tips
Practical Tips
Start with short patterns (e.g., 16 steps).
Use one effect per channel to stay organized.
Store variations using pattern banks.
Shuffle and Stutter are great for breaks and fills.
Combine Stop + Scratch for dramatic transitions.
In Energy mode, Dry/Wet blending keeps the overall volume steady.
