Pitch detection delays timers?

Games
#1

So I will have these notes spawning, and all is fine unless i hold a pitch that i sing. So if i hold the pitch, the notes literally will pause until i stop. Why is this, and how can i fix it!?

I didn’t fully understand the question, but are you on iOS? For performance reasons, audio recording shuts off audio playback. If you need simultaneous recording and playback, you need to use the (advanced) Audio Session APIs to change the mixing mode to audio.PlayAndRecordMixMode.

Thanks, but i’m not using audio playback except once, before the recording even matters. The playback and recording is working fine. The problem is that when I constantly hold down a note, the other notes stop. For example, it is as if playing the correct pitch deletes the note and stops to notes.

Does this make since? So whenever I hold down a note, as long as it is the correct (variable f) above, all of the notes appear to stop moving. [import]uid: 59735 topic_id: 20936 reply_id: 82725[/import]

Is there a logic bug? If the note doesn’t change, then you don’t get a ‘newnot’ and you never play anything. The sound you are playing will eventually come to an end (you are not looping the sample) so eventually nothing will be playing until the note changes.

Also, be careful about how you use loadSound. It was meant to be called to preload your samples (say at launch time) into memory because loading may not be instantaneous. And generally speaking, we are discouraging you from calling loadSound on the same file that is already loaded.
