Quick-Start Presets

Here's a string you can send to Signal Generator to create some general-purpose presets:

wipe;import1 m=r,f=500,p=25,b=10,h=p;n1=Laser Control;import2 m=t,f=1k,p=0,h=f;n2=Saw Left;import3 p=100;n3=Switch Saw Right;import4 m=s,f=440,s=153,a=4,h=f;n4=Music Maker;import5 m=r,f=40m,p=50,b=1,s=1m,h=f;n5=40MHz Sine Wave Baby!;import6 m=s,f=500,p=50,b=10,s=50,j=5,a=2,h=p;n6=Small Sine;import7 m=r,f=1.5k,p=50,b=10,s=50,j=10,h=p;n7=1.5kHz ~ 50% PWM Laser Control;w;import m=r,f=1k,p=25,b=6,s=100,j=10,h=f

Here's a bunch of presets to get you started controlling a laser:

wipe;import1 m=r,f=100,p=25,b=10,j=5,h=p;n1=100Hz Laser Control;import2 f=222;n2=222Hz Laser Control;import3 f=333;n3=333Hz Laser Control;import4 f=440;n4=440Hz Laser Control;import5 m=r,f=1.5k,p=50,b=10,s=50,j=10,h=p;n5=1.5kHz ~ 50% PWM Laser Control;import6 f=666;n6=666Hz Laser Control;import7 f=720;n7=720Hz Laser Control;import8 f=810;n8=810Hz Laser Control;import9 f=777;n9=Captured Laser Control;import10 f=1k;n10=1kHz Laser Control;import12 m=s,f=500,p=50,b=10,s=50,j=5,a=2,h=p;n12=Small Sine @ 25% Amplitude;w;import m=r,f=500,p=50,b=10,s=50,j=5,h=p

Here's a loop command that will gently pulse a laser / speaker / whatever with a 1kHz Square wave, for ever..

r;1k;b10;loop=p5;~100;p10;~700;p15;~140;p20;~130;p30;~120;p40;~110;p50;~100;p60;~110;p70;~120;p80;~130;p90;~140;p95;~100;p100;~650;p95;~66;p90;~200;p80;~180;p70;~170;p60;~160;p50;~150;p40;~160;p30;~180;p20;~180;p15;~150;p10;~150;p5;~150

loop

Or a nice pulse every one second, for ever..

r;1k;b10;loop=p10;~800;p15;~9;p20;~8;p30;~7;p40;~10;p50;~6;p60;~10;p70;~11;p80;~12;p90;~13;p100;~14;p95;~6;p90;~10;p80;~10;p70;~10;p60;~10;p50;~10;p40;~10;p30;~10;p20;~10;p10;~10

loop

Or load that loop into preset slot 3, for later use..

r;1k;b10;loop3=p10;~800;p15;~9;p20;~8;p30;~7;p40;~10;p50;~6;p60;~10;p70;~11;p80;~12;p90;~13;p100;~14;p95;~6;p90;~10;p80;~10;p70;~10;p60;~10;p50;~10;p40;~10;p30;~10;p20;~10;p10;~10

Run it..

My current dev module's settings, for the hell of it..

Yes, that's all one line - just throw it in - and yes, let me tell you about loop 8 and the wonderfulness of Chat GPT..

SO, I asked, "can you give me millisecond timings for a nice slow pulse?", and of course Chat GPT had no effing clue, responding with heart-rate information. OKAY. So I said, "no, I mean, if I wanted to generate a pulse, setting voltages or PWM, what timings (and also percentages of Volts) in milliseconds would I need for each step?"

It then went on to provide a huge spiel of information about frequencies and duty cycles and so on. *sigh*. I got frustrated and said, "NO. I'm looking for a list if timings that will give me a nice pulsing effect"

Chat GPT responded,

I apologize for the confusion. Here are some general timings that you could use to create a pulsing effect:

1. A pulse every 2 seconds: High state for 100ms, followed by low state for 1900ms.

2. 

Then I had that "bingo" moment when, remembering that I am dealing with a learning machine, I said, "Here's an example that gives a nice pulse once per second ('p' sets the PWM % and '~' sets the millisecond delay - I'm looking for a better set of numbers): p10;~800;p15;~9;p20;~8;p30;~7;p40;~10;p50;~6;p60;~10;p70;~11;p80;~12;p90;~13;p100;~14;p95;~6;p90;~10;p80;~10;p70;~10;p60;~10;p50;~10;p40;~10;p30;~10;p20;~10;p10;~10"

From this point, Chat GPT provided working examples which I could throw directly into Signal Generator! It's first response was this:

p10;~500;p20;~500;p30;~500;p40;~500;p50;~500;p60;~500;p70;~500;p80;~500;p90;~500;p100;~500;p90;~500;p80;~500;p70;~500;p60;~500;p50;~500;p40;~500;p30;~500;p20;~500;p10;~500;

Then I asked, "Can you give me something faster and more natural?", and got the command you see in loop8, above. Not bad.
