end

---------------------------------------------------------------

the only difference is in the declarences of inputs and outputs

before i hadd added the declarations of in2 and out2 to the "code" dection i didnt get any errors but after a series of trials to update i got this in the output window.

what am i doing wrong?

macs t1, dc, in, in2, 0x7fffffff;

You have 5 parameters in this instruction when there should only be 4.

Aside from the above, EFX Tubedrive is a .dll plugin, so be aware that some things cannot be done to it without recompiling the plugin (C++ source code).

[color=gray] btw, where is TigerM? i haven't seen him for a long time... i start to miss... [/color]

laserbeak

that the type of instruction it is that it only allows 4 parameters?

so what do i do with my extra input? oh wait then i will have to look at the c++ source. i wonder, is it available?

laserbeak

cool thanks guys.

Russ

All Dane instructions take that basic form.

i.e.
opcode result, a, x, y;

To use an extra input, you would use a seperate instruction to work with that input, etc.

laserbeak

hehe just read that thanks but it still wont really do anything will it? besides maybe let audio pass?
macs t1, dc, in, 0x7fffffff; ------> if i used this
macs t1, dc, in2, 0x7fffffff; ------> would this be legal? what do the hex numbers represent? not that far in the tutorial yet

Tiger M

I miss you too, Max

Russ

It is kind of hard to explain as it depends on what you are trying to do. You should really read the guide. The hex numbers are just numbers represented in hex, nothing more, except that it is in 2's compliment form (search the internet). 0x7FFFFFFF in this case is bascially equivalent to 1, so the above instruction works like this:
t1 = dc + in * 1 (t1 = dc + in)
t1 = dc + in2 * 1 (t1 = dc + in2)

You can do that if you want, but you are not going to get the result you are expecting. 't1' is just going to end up being the value of the second instruction, so the first instruction basically will not do anything. You would want to either devide both inputs in half and then add them together (in which case using a monomix plugin would be an easier solution), or you would need to basically do the same thing to the second input that you do to the first input (throught the whole plugin code), and then store the results in a seperate register.
i.e.
macs t1_left, dc, in_left, 1
macs t1_right, dc, in_right, 1

Again, you best bet would be to read through the guide so you have a better understanding of how it works.

laserbeak

thanks alot i have been reading about this in the guide you're comments are very reassuring.
a snippet from the guide shws this
control In1 Level=0x0, In2 Level=0x0;
does that say that there are 2 sereo sliders initialized to 0?

Russ

Yes.

<edit>
BTW: Not stereo sliders. Just 2 sliders.

laserbeak

ok thanks.
this looks interesting.
