Laundry Soup is a trigger sequencer that takes text as input. If you connect a clock signal to the "clk" input, and type 1 in the top text box, the top "out" output will send a trigger each clock. 2 sends a trigger every 2 clock signals. 31 sends a trigger on the 1st and 4th clock signals, and then repeats this pattern forever or until reset.
Lets represent a clock signal like this:
xxxxxxxx
If the value
2
is input into a text field, the output signal will be:
x-x-x-x-
You can see this illustrated on the scope in the screenshot above.
The input and output of the 2nd row is:
31 ---> x--x (repeating after 4 beats)
In The 3rd row:2131@8, the @8 means: repeat the pattern every 8 clock signals. In this case the original pattern has length 7 (2 + 1 + 3 + 1 = 7), so normally it would repeat every 7 clock signals.
2131 ---> x-xx--x (repeating after 7 beats)
2131@8 ---> x-xx--xx (repeating after 8 beats)
A rest can be programmed by using the number "0". If Laundry Soup is triggered by 16th notes, the pattern 00004 (or equivalently 0@4,4) can be used to trigger a snare drum sound on the backbeat.
8 ---> x-------
07 ---> -x------
00004 ---> ----x---
Another way to generate the backbeat pattern using the @ symbol:
0@4,4 ---> ----x---
The 5th row shows how multiple patterns can be combined. 311@16,2@16 means: 311 for 16 beats, and then 2 for 16 beats.
311@16 ---> x--xxx--xxx--xxx
2@16 ---> x-x-x-x-x-x-x-x-
311@16,2@16 ---> x--xxx--xxx--xxxx-x-x-x-x-x-x-x-
The bottom pattern could also be written like this, using square brackets:
[311,2]@16 ---> x--xxx--xxx--xxxx-x-x-x-x-x-x-x-
Comma-separated patterns inside square brackets, and followed by an @ will sequentially output each pattern for the specified number of beats. For the pattern above, it will output: 311 for 16 beats, and then 2 for 16 beats.
To program a rhythm that divides the incoming clock by 16, the proper input is NOT 16. Values greater than 9 steps must be enclosed in angle brackets <16>
16 ---> xx----- (Laundry Soup interprets this as a 1 and then a 6. This pattern repeats every 7 beats)
<16> ---> x--------------- (repeats every 16 beats)
Global Clock (clk): Increases each row's absoluteStep by 1.
Global Reset (rst): Resets each row's absoluteStep to 0.
Individual Clock (clk): Increases the row's absoluteStep by 1. If a cable is plugged in, the row ignores the Global Clock.
Individual Reset (rst): Resets the row's absoluteStep to 0. If a cable is plugged in, the row ignores the Global Reset.
Individual Row Output (out): The output of the row's pattern. Outputs 10 volts if:
A) The clock signal is sent to the Global Clock or Individual Clock input jack
AND
B) The pattern ought to trigger on this absoluteStep
Individual Row EOC Output (eoc): Sends a trigger on the 1st step of the row's pattern.
The display shows a few things:
- Top row: Which step number the sequence is currently on, starting with 1
- Bottom row: The total length of the pattern
- If the display is red, that means the pattern has a pending change and will switch to the newly typed pattern when it reaches step 1. ie: changing the pattern is sync'd to the old pattern length. Click the display to force the pattern to reset on the next clock.
