Minim general question

I'd like to use Minim to let users produce 5 different signals (pink and white noise, saw, sine and pulse waves) by providing input. It's the first time I'm programming sound, and even though it kind of works now, I was wondering:

1. should I have one lineOut per signal?

2. if I should have one lineout per signal, how can I do it? (i've tried using the setOutputMixer() function, but it returns an error (the function does not exist).

I'm using Minim 2.0.2 on OS X 10.6.

Thanks!

Object-oriented timer

Newbie here. I've been struggling with making timers. This is what I need:
- I have an object with a boolean available.

- If another object gets close to it,

   available = false

   start a 5 second timer

   perform an action while that timer works

- when the 5 second timer is done,

   start a 10 second timer

- when the 10 second timer is done,

   available = true

My problem is how to make one timer switch on and off the other one, more than one time.

This is my Timer class:
2. /* Very basic timer class
3. takes one parameter, max. time in sec.
4. remember to make it run on main loop!
5. */
7. class Timer
8. {
9. int time, startTime, currentTime, maxTime;
11. Boolean running;
13. Timer(int _maxTime)
14. {
15. maxTime = _maxTime;
16. stop();
17. }
19. void reset()
20. {
21. currentTime = startTime = millis()/1000;
22. time = currentTime - startTime;
23. }
25. void start()
26. {
27. running = true;
28. }
30. void stop()
31. {
32. running = false;
33. }
35. void work()
36. {
37. if(running)
38. {
39. currentTime = millis()/1000;
40. time = currentTime - startTime;
41. }
42. }
44. Boolean isDone()
45. {
46. if(time >= maxTime)
47. {
48. return true;
49. }
50. else
51. {
52. return false;
53. }
54. }
I guess there is a logic flaw somewhere, but I just cannot see it. Any help will be greatly appreciated!

Timing problems

Hi there, newbie speaking.
I'm writing a program with two timers that should work together: when one ends, the other one starts, and some booleans are changed. Now, all works well with timer1, but timer2 fails miserably. When it's done, it's supposed to change a bool from false to true, but it just doesn't. And I am not sure what I am doing wrong!

Here's the code, any help will be much appreciated!
2. //testing Timer class
4. Timer scoreTimer;
5. Timer cooldownTimer;
6. PFont font;
7. Boolean available;
8. int score = 0;
10. void setup()
11. {
12. size (400, 400);
13. scoreTimer = new Timer(5);
14. cooldownTimer = new Timer(3);
15. font = createFont("Helvetica", 22);
16. textFont(font);
17. available = true;
18. }
20. void draw()
21. {
22. background(0);
23. stroke(255);
24. line(200, 0, 200, 400);
25. fill(255, 0, 0);
26. text((scoreTimer.time), 100, 100);
27. fill(0, 255, 0);
28. text(cooldownTimer.time, 300, 100);
29. checkTimers();
31. if(mouseX > 200 && available == false)
32. {
33. score();
34. }
36. if(scoreTimer.isDone)
37. {
38. cooldown();
39. }
