I was wondering if there's a possibility that a variant of the RCD firmware/hex is floating around that might do even longer divisions.

Now I have an RCD and an SCM, I'd really like a super RCD that I could use for triggering x1, x4, x8, x12, x16, x20, x24, x28, x32 etc for triggering bar length progressions.

I do understand I could just clock the x4 out of my rcd into another rcd, but figured I'd ask if a specific version might exist.

isn't this what the RCD breakout panel is for? goes down to x64 if i remember correctly. it's very cheap, you can even buy a kit (i haven't built mine yet...)

If you have the avrisp then grab code from the 4ms site here.

Quote:

if (switchread==0) {
t=7;
d=adc>>5;} //LL: d=0..7, masked by t=0b00000111 gives on jack 1 DIV 1-8
else if (switchread==(1<<ROTATE_JUMPER2)) {
t=15;
d=(adc>>4)+8;} //LH: d=8..23, masked by t=0b00001111 gives: DIV 9-16|1-8
else if (switchread==(1<<ROTATE_JUMPER1)) {
t=31;
d=(adc>>3)+16;} //HL: d=16..47, masked by t=0b00011111 gives: DIV 17-32|1-16
else {
t=63;
d=(adc>>3)+32;} //HH: d=31..95, masked by t=0b00111111 gives: DIV 32-64|1-31

Those are the jumper settings - so the t= in the various ones is the top division for that jumper setting ( minus 1 - in the code generally look at the outs and divisions starting at '0'). You'll want to up that t= value to the top division you're wanting for whichever switch setting.


The various gate and jumper sections have parts that look like:
Quote:
if (GATEMODE_JUMPER){
if (o0==((((0+d)&t)/2)+1)){OFF(OUT_PORT1,0);}
if (o1==((((1+d)&t)/2)+1)){OFF(OUT_PORT1,1);}
if (o2==((((2+d)&t)/2)+1)){OFF(OUT_PORT1,2);}
if (o3==((((3+d)&t)/2)+1)){OFF(OUT_PORT1,3);}
if (o4==((((4+d)&t)/2)+1)){OFF(OUT_PORT1,4);}
if (o5==((((5+d)&t)/2)+1)){OFF(OUT_PORT1,5);}
if (o6==((((6+d)&t)/2)+1)){OFF(OUT_PORT2,7);}
if (o7==((((7+d)&t)/2)+1)){OFF(OUT_PORT2,6);}
} else {
if (++o0>((0+d)&t)){ o0=0;}
if (++o1>((1+d)&t)){ o1=0;}
if (++o2>((2+d)&t)){ o2=0;}
if (++o3>((3+d)&t)){ o3=0;}
if (++o4>((4+d)&t)){ o4=0;}
if (++o5>((5+d)&t)){ o5=0;}
if (++o6>((6+d)&t)){ o6=0;}
if (++o7>((7+d)&t)){ o7=0;}

So could maybe change the upbeat one to:
if (++o0>((0+d)&t)){ o0=0;}
if (++o1>((3+d)&t)){ o1=0;}
if (++o2>((7+d)&t)){ o2=0;}
if (++o3>((11+d)&t)){ o3=0;}
if (++o4>((15+d)&t)){ o4=0;}
if (++o5>((19+d)&t)){ o5=0;}
if (++o6>((23+d)&t)){ o6=0;}
if (++o7>((27+d)&t)){ o7=0;}



or something like that - poke with it.

I need to buy a burner and look into this some more.

Although my worry is I'll get carried away and before I know it I'll have 12u full of RCD's all going crazy.

Kind of thinking about a second rcd myself.

Wow, I'm very interested in this. I've often thought it would be cool to have the RCD rotating non-sequential divisions.

bmsith - have you actually had this working with your code tweak? Has anyone?

Yeah, I've changed what the jack divisions put out, as well as some other things like changing some jacks to rotate in increments of 2 while others do 1 as shipped...
there may or may not be some much cooler stuff on the rcd being worked on by bigger brains than myself we can all look forward to.
