The Turing Machine V1. Works with V2.0C
TURING1.MAP (Size: 1,47 KB / Downloads: 83)
This V1 got only the left shift option. Sounds best with any global scale enabled.
It uses the CV Input as 'switches' where 0 Volt means switch OFF another value means switch ON.
CV Input 1 : Set bit 0
CV Input 2 : Reset bit 0
CV Input 3 : Invert bit 0
CV Input 4 : Random bit 0
Of course you can replace the CV inputs with any other source easily.
If you got a trigger expander then you can see the turing parts nicely on Triggers 1-12.
You can use variables C, G and H to change some turing settings (see variables below)
The turing machine is connected to the sequencer and starts if the sequencer is started.
Var A: Switch/CV Input threshold (Initialized)
Var B: Type of trigger (Initialized w Trigger E1)
Var C: Amount of used turing bits
Var D: Helper variable for calculation (Initialized)
Var E: Used for program flow
Var F: Variable to hold the turing bits
Var G: Multiplicator for turing output (if less bits are used to get the full range anyways)
Var H: Pitch Offset
So how does it work. In general it is a turing machine which uses the 4 CV inputs. If Input 1 is on (high) then turing bits (on the LSB) are set.
If Input 2 is on (high) then turing bits on the LSB are reset. If Input 3 is on (high) then the LSB of the turing value is being inverted. If Input 4 is on (high) then the LSB of the turing value with randomly be set or reset.
Rows 00 to 0A will use the Clock output and on a raising edge (and running sequencer) then the turing value will be shifted. Var E will be set then as well (if sequencer is running AND a raising edge) which is being used in later checks then (like if Var E is set then other commands following can be executed).
Row 0C to 0E do the check for the first input and will set the turing LSB if the input was high.
Row 10 to 12 do the check for the second input and will reset the turing LSB if the input was high.
Row 14 to 17 do the check for the third input and will invert the LSB if the input was high. Checking Var E is taking care that the LSB is not inverting all the time but only once on each raising edge of the clock.
Row 19 to 1D will check if Var E is set and then it will output the current turing value to output CV1 and generates a trigger. The value is optimized via multiplication and an offset so it is audibly more interresting.
Row 1F to 25 will check Input 4 and will randomly set or reset the LSB of the turing value if the input was high.
Note: the block row19-1D and row 1F-25 could/should be swapped for the better readability but it doesn't really matter for the result as always Variable F is being used for the output.
Row does reset Variable E again which takes care that all the important stuff up there is always only being executed once when the raising clock with a started sequencer happened.
Row 29-36 does generally a bitwise check of all the turing bits and outputs the bit states on the Trigger 16 Expander (NSA1) outputs 1-12. This gives a nice visual feedback of the turing value.
