Hi Carl: Kernel is 2.4.26, Planet CCRMA, low-latency. GCC is 3.2.2, Wine version is 20031118. VSTserver and vsti are the latest versions from Kjetil's site (0.3.1 and 0.0.3). Libfst is 1.5, jack_fst is 1.2. I had a most interesting time last night playing around with various VSTi plugins. Probably the weirdest thing I did was to run a couple of plugins (Oberon and PM4) via jack_fst (separate instances) then drive them with a MIDI sequencer (Sequencer Plus Gold) running under DOSemu. Very strange to see an MS-DOS MIDI application driving two VSTi plugins while in Linux. ALSA + JACK + Linux rocks *hard* ! Response from the plugins was fine, with no latency issues. One thing I noticed: after some time the plugins stopped responding to attempts to move sliders and knobs. At that point the plugins had efectively crashed, even though the sequencer could still drive them (I just couldn't make any changes to the plugin's settings). This is apparently a known issue. The only problem I had with stuck notes was when I removed a connection from the MIDI patch bay while the synth was still sounding. I simply reconnected the sequencer and the synth, hit the key on my CZ101, and the stuck note was gone. I had no trouble with stuck notes while playing the plugins via the sequencer or my Casio keyboard. Screen redraws are slow on my system (800 MHz Duron), but I suspect that's due to the low-powered CPU. My video system is running an nVidia GForce2 with the nVidia driver. I'll revise the Linux VST/VSTi tutorial this weekend. I'm impressed by the performance of both fst and vsti, and it's time to update that tutorial. Serious congratulations to Kjetil, Paul, and Torben !
