| Summary | 0007866: Crash and/or timing-offset when editing regions during playback | ||||
| Description | Editing a region during live playback can result in a failed buffer-refill. | ||||
| Steps To Reproduce | Given 2 tracks, Generate a region of "noise" (pink or white, whatever) on one track. Copy the region (in lock-drag) down to the second track, and invert polarity so the noise is silenced during playback. During playback, select a region and adjust the region's "gain" setting (*) repeatedly. Changing the gain should make the noise audible. Returning it to unity should silence the noise again. Occasionally, one of two things occurs: * crash (see below) * timing offset: noise plays full-volume because timing is offset (this can be verified by listening to music or click instead of noise). After a few seconds, the problem will fix itself (buffer refill?) (*) other operations, like trimming the region start, can also trigger the behavior and crash. But I find this is easiest. | ||||
