Hi,

I was looking at Noise Engineering - Variatic Eruption manual and it gave me some ideas of things i wanted to try with my teletype. But although i understand the basis of teletype language i am far from being a math guy…

So here are the things i want to do :

1 - Convert decimal numbers to binary
2 - Create a pattern ( of 1 and 0 … ) from a binary number in the tracker

So is there any way to achieve this ??? :kissing:

can you be more specific on what you want to achieve ? i’m curious…

@martinmestres that’s a really cool idea. You could effectively make each pattern step an entire pattern of gates. Might need some additional string or array features in the language though.

#4

I don’t know exactly yet, but it could open up things like stocking decimals numbers in P.0 reading one of them to set P.1 sequence of pulses:

Ex: reading 1320 in P.0 could give that sequence in P.1:

0
0
0
0
0
1
0
1
0
0
1
0
1
0
0
0

So you could have 64 sequences stocked in P.0, and that would be a good start for a lot of deep scenes. :heart_eyes:

I hope you are wrong :cold_sweat:

#6

so let’s say X holds your value, then you could do something like this (i don’t have access to tt right now so this might need some tweaking):

P.PUSH MOD X 2
X DIV X 2

this will need to be executed N times where N is the number of steps, so you could either do it in M script or put it in a trigger script and loop that. the limitation is 15 bits though, since numbers are treated as signed int, so the max value is 32767 which gives you 15 bits.

#7

slightly off topic, but:

given number X translate to triggers 1-4 in binary

TR 1 NZ AND X 1
TR 2 NZ AND X 2
TR 3 NZ AND X 4
TR 4 NZ AND X 8

basically does a bitwise AND with the binary position (power of 2) and checks if this is zero or not

on topic:

for number X, looking at step Y (16 bit)

TR 1 NZ AND X LSH 1 Y

that’ll do it. just increase Y for the step position, X is the “sequence” of 16 bits.

so yes, TT can do all this-- with one line. math is cool yeah?

Thank, it may take a while for my brain to process this :pensive:

So if i understand well:

means " if trigger 1 is not equal to 0"

I don’t get it…

With X = 1320 and Y position in pattern

1320 LSH 1 0 = 0
1320 LSH 1 1 = 0
1320 LSH 1 2 = 0
1320 LSH 1 3 = 0
1320 LSH 1 4 = 0
1320 LSH 1 5 = 1
1320 LSH 1 6 = 0
1320 LSH 1 6 = 1

etc…

So i’m not sure about how to write the entire “BINARY PATTERN” ( in P.N 1 ) from my decimal ( in P.N 0 ) in One TRIG. I’m thinking about something like that:

[quote]P.N 0
X P.HERE
P.N 1
P.I 0
L 0 63 : P.PUSH X LSH 1 I [/quote]

???

Why the need of a number to convert it to a sequence of 0 and 1s ? Why not simply generate the sequence with TOSS ?
L 0 63 : P.PUSH TOSS

#10

Ha i see ! Save a lot of space that’s the point.

#11

AND is bitwise Operation.
Any bits A and B only translate to 1 if both are 1.
You have your X in bit representation and a bitmask of 1 (0000000000000001) which you shift towards the left and therefore always gives you the next position in the bit representation of X.

Quite cool isn’t it :smile:

This thread is so promising !!!
Let’s get crazy…how to do this in base 4, so you generate patterns of 0/1/2/3, allowing you to trigger the 4 trig outputs ? imagine the rhythm sequences…

#13

I still don’t get why i need to put ab AND here…

@tehn

Ok think i misunderstood that thing.

I can’t make it work, i tried different adaptations and i can’t reach what i was thinking about:

• Stock decimals in P.N 0
• Convert the Decimal to Binary number
• Transform the Binary number in a pattern of 0 and 1 and set it in P.N 1

#14

It’s a low level “trick” if you will. Getting just the bit(s) you want, in very short code.

#15

Ok i managed to do what i wanted. I will make some modifications and post the stuff here when it’s done.

#16

Ok this is the basis of the Scene that could open on a lot of stuff:

So put a regular clock in INPUT 2 turn PARAM knob to set a value to extract pattern from and TRIG INPUT 1 .

This is the basis, i will think about something more advance now, like chaining 2 or 4 sequences to get 32 or 64 steps patterns.
