Hi, in principle LinuxSampler VSTi already works quite nicely (Andreas and me are testing it under various sequencers, I'm using reaper),
what currently still needs to be fixed is the ability to use FX sends in LinuxSampler VST since it will allow to provide midi controllable FXes
for GIG samples using the sequencer's FXes. (eg reverb,chorus etc).
As cuse said not sure if we can release it till the end of the year but the finish line is in sight
I hope that VST users will find LS VST useful as it provides perfect integration with familiar sequencer environments while retaining all
chracteristics, functionalities and performance of LS. LS VST has even the advantage that by opening multiple instances you can take advantage
of multicore CPUs and achieve a polyphony of several hundreds of voices (the bottleneck is usually the disk).
As for 64bit support, an unofficial mingw version (gcc for windows) already seems to support generating 64bit binaries on WIN64http://sourceforge.net/projects/mingw-w64/
so we could try to compile LS VST in 64bit mode and see if it works.
BTW does reaper now support 64bit VSTis on WIN64 ? (probably no LS developer currently has a commercial 64bit capable (cubase,sonar) VST sequencer to test.
keeping you posted about the progress
