Clarification: 1] Segfault: The segfault is only triggered when changing the number of disk streams during runtime *and* when an instrument/channel is currently loaded 2] Error: The error only happens if GetChannelInfo is called before EngineChannelBase finishes caching the samples. For example, if the cache is not finalized you see something like the following. (Notice "INSTRUMENT_STATUS: -4", this is the error QSampler displays). EngineChannelBase: progress 36EngineChannelBase: progress 36 RenderAudio(Samples=1024) Condition::WaitIf: bCondition=0 TimeoutSeconds=0 TimeoutNanoSeconds=0 Condition::Waitif() -> LOCK() Condition::Waitif() -> LOCK() passed Condition::Set() -> LOCK() Condition::Set() -> LOCK() passed Condition::Set() -> broadcasting 'false' condition Condition::WaitIf: bCondition=0 TimeoutSeconds=0 TimeoutNanoSeconds=0 Condition::Waitif() -> LOCK() Condition::Waitif() -> LOCK() passed Condition::Waitif() -> waiting for 'true' condition RenderAudio(Samples=1024) RenderAudio(Samples=1024) RenderAudio(Samples=1024) RenderAudio(Samples=1024) RenderAudio(Samples=1024) LSCPServer: Got command on socket -1, calling parser.

For some strange reason, it seems the greater the number of disk streams, either the longer it takes for the sample cache to be generated, or the sooner GetChannelInfo is called. The error basically prevents LinuxSampler from working: any subsequent operations, such as Quiting or Removing-the-Channel, all throw the same Error:-4. ------------------------------------------------------------------------------ The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.
