Hello, I have been fooling around with ls this weekend. I rechecked out ls and rebuild it on Friday (not sure if there was any change in cvs or not). I have found it to perform pretty well over the weekend. I setup an alsaseq filter to set all noteoff events to have a velocity of 1 and was able to play one of my patches without any issue! I did not reset the sampler or the channel for two days and was able to periodically sit down and jam. I did not notice any voice dropping or errors. Very nice! (this was with asm optimizations) However, none of the other patches I tried performed quite this well. On all of the other patches I try I eventually (after a minute or so) see: No unused stream found (OrderID:32) - report if this happens, this is a bug! No unused stream found (OrderID:33) - report if this happens, this is a bug! No unused stream found (OrderID:34) - report if this happens, this is a bug! No unused stream found (OrderID:35) - report if this happens, this is a bug! No unused stream found (OrderID:38) - report if this happens, this is a bug! No unused stream found (OrderID:39) - report if this happens, this is a bug! No unused stream found (OrderID:46) - report if this happens, this is a bug! ... No unused stream found (OrderID:66) - report if this happens, this is a bug! No unused stream found (OrderID:67) - report if this happens, this is a bug! No unused stream found (OrderID:68) - report if this happens, this is a bug! 0x4046d1e0Disk stream not available in time! 0x4046d1e0Disk stream not available in time! No unused stream found (OrderID:69) - report if this happens, this is a bug! ... No unused stream found (OrderID:90) - report if this happens, this is a bug! 0x4046d1e0Disk stream not available in time! No unused stream found (OrderID:91) - report if this happens, this is a bug! 0x4046d1e0Disk stream not available in time! 0x4046d1e0Disk stream not available in time! No unused stream found (OrderID:98) - report if this happens, this is a bug! 0x4046d1e0Disk stream not available in time! After this starts happening the voices drop at the same time as the Disk stream not available in time errors. Also, if I remove the channel after this happens and add a channel with the patch the works well I see this behavior. I can then kill ls, restart ls and add a channel with the patch that works well and it behaves properly. I'm not sure what the difference between that patches that I am using is that would allow one of them to work and not the others. They are all large (.9 - 1.8 GB) piano patches. I may ask Josh how gig support in libinstpatch is comming to see if it might be possible to use that to zero in on the differences that are causing these errors. I tried to find a demo patch that might illustrate the noteoff velocity issue I am encountering, but can only seem to find demo recordings of patches. I'm pretty sure that if I could create a one note patch that had the same sample (maybe just a sine wave) for noteon and noteoff I could recreate the problem. Maybe if libinstpatch gig support is mature enough I can use that to create such a patch. Let me know if there is any more information I can provide to assist. -Garett Vladimir Senkov wrote: >Garett, > >I'm glad it built.
