Why is the sound getting disrupted on button press?
« on: November 07, 2011, 07:09:22 pm »
can somebody explain me why the sound gets distorted?
Here's the code:

Could you post the source and executable files so we can try it out for ourselves?  What kind of distortion are you talking about?

source is already posted :P
Executable file:

EDIT: the notes sounds weird whenever I press the buttons.

Yes but it would be a real pain to type that in if we wanted to make changes while we tested x.x

I don't have a link access with me right now so I'll post the on-calc source later (around 8:30)
but you can try the executable. :D

Yeah I can see what you mean, it sounds like the entire program slows down when you press keys.  I am completely unsure of what might be causing this, it sounds really strange o.O We might need some help from Runer or Quigibo since they have a better understanding of how the sound routines work.

Putting FnOff at first solved it XD
Thanks for ppl who were in IRC XD

What does FnOff do btw? Did it just remove the busy indicator? Because I remember in TI-BASIC, when pressing keys it slowed things down by about 1% and I saw it happen in some ASM games too (especially in MirageOS games that didn't disable MirageOS interrupts)

Apparently, FnOff turns off the interrupt mode :D
so it turns off MirageOS's silly interrupt, making sound output better.

Ah that explains it then. Don,t use L2, though, because it messes Mirage OS up IIRC. Those interrupts areNt really useful unless you want to slow the game down or quit in the middle of it (I think ON+MODE or something, but it was not always stable)

It doesn't work in every game but it did in some, like Galaxian: You need to hold down ON then press the F keys (IIRC, F1 is the slowest and F5 the fastest), but sometimes I think the opposite effect occured or every key gave the same slow down

ON+Y= for the slowest, ON+Graph for the fastest, ON+Zoom for normal speed. These settings seem to be somewhat broken on the TI-84+(SE) calcs, tho.

EDIT: Ninja'd. Oh, well. As DJ said, sometimes these things don't work at all. That usually happens when the game decides to turn interrupts off or they set up their own interrupts.
