I don't have any idea of what to start with, what should I do?

For guidance with using RolloSONIC - starting from beginner and progressing much further - see the RolloSONIC Tutorials. These tutorials not only explain how to do things with RolloSONIC, - they actually show you!



I don't hear any sound, what can I do to make it function?

Try the following troubleshooting steps:

  1. Make certain that you have pressed the "Start" button.
  2. Make certain that the "Output Device" setting of at least one of the sound-creating or sound-effecting modules has been set.
  3. Make certain that the selected sound-card is the correct one, try the others if necessary. Note that selecting the "...Sound Mapper" will cause it to use the Windows default sound-adapter for that task (a separate sound adapter can be chosen for input and output).
  4. While watching the value indicated by the "Current sound latency" indicator at the lower-right of the main program window, adjust the output (lower) latency control slider (at the upper mid/right of the main window). You should see a "Current sound latency" value ranging somewhere from about 25 to 512. The number should change as you adjust the slider. If it is stuck on one number, or if it still has "---' indicated instead of a number, then something is not functioning or it is not started. Note that it is normal for a number to be stuck there when you press the "Stop" button and/or when you have no more sound devices selected for output.
  5. Make certain that you have version 1.0a2 or later; The version is viewable in the "About" of the program.
  6. Notice: The easiest way to test whether the sound is functioning is to open the program and simply create one "Oscillator module" and then press the "Start" button. This is the most basic sound-yielding configuration. To switch between output devices (sound cards) in this configuration, try changing the "Output device" drop-down at the bottom of this module. You can change this at any time, no need to stop the system first.
  7. Note that at this time (November 8th 2006), RolloSONIC only supports 96KHz sound-input/output. If, for some reason your sound card does not support this, the sound will probably not function.



The output is crackly and/or dirty sounding, how do I fix it?

This is likely due to the output-latency slider needing to be adjusted, particularly when it is set too low.

The output-latency slider is the lower-slider located at the middle-top of the program's main user-interface. To adjust this slider, create a simple configuration, such as one with just an Oscillator running at a clearly audible frequency (pitch) and then, while it's "Started" (via the Start button), listen to the tone outputted and adjust the output-latency slider. Also, while doing this, watch the current output-latency indicated at the program's lower-right. You probably want to get it to be stable at around 40ms for best performance and sound-quality.

Due to some glitchiness in the system, it may be necessary to try stopping and restarting the sound-output (via the Start and Stop button) - with the slider at different locations, each time trying to adjust it while it's going. This is sometimes necessary because sometimes it will not be controllable, or will stay at or near zero (the actual output-latency) when having been started with the slider at a given location.

Since this setting is saved when the program is exitted and restored upon program restart, it should not be necessary for you to do this every time, but note that different computers and sound-output devices (sound cards) will act differently and so it may be necessary to re-adjust if something in the system has changed.
