I'll admit, I love the variety, sample quality and sound editing capabilities of SampleTank instruments. However. I have all but stopped using ST in favor of other sampling platforms [mod redacted] due to what I will label SampleTank's "reliability", or lack therein.
You see, I use virtual instruments exclusively within a live performance VST host setting where there is no room for error or uncertainty. ST4 was one of my first sampling engines, and I used it extensively, initially within Gig Performer, then within Cantabile as the VST host application. With both products, I experienced the same reliability issue. After multiple iterations of saving songs and setlists in Gig Performer and Cantabile, the SampleTank instruments would sometimes lose or alter their sound spontaneously and without me making any changes to the SampleTank patches. Either the instrument would not produce sound at all (even though ST still showed the instrument as loaded in a slot), or the sound would be so low as barely audible (as evidenced by the ST level meter), or the instrument would be a quarter-tone or more flat. In every instance, merely selecting and reloading the same instrument patch would fix the problem. But imagine the horror of pressing a key in live performance only to hear nothing at all, or worse yet, hearing something badly out of tune...
Since this same phenomenon has occurred in two completely different VST host environments, and since I have only experienced this loss of sound/pitch issue with SampleTank (among 50 or so other VST instruments I own), the evidence points to an issue within SampleTank. I have seen others post of similar issues when using ST within a DAW, so I know that I am not the only one that has experienced this.
So my question for the SampleTank community is this: has anyone else experienced reliability issues with saved ST instrument patches within a DAW or VST host, and if so, were you able to "fix" it or does the issue persist (albeit intermittently)? I sought out IKM's assistance, but the issue is hard to reproduce on-demand, so instead I have sadly moved away from using SampleTank for anything I deem critical for live performance. I remain eternally optimistic that someday one of the bright IKM engineers will identify the flaw and fix it in some future release. Until then, I remain in exile.
