Lmms works wonderful.
DON'T UPGRADE TO 0.4.15! DOWNLOAD LMMS 0.4.13 INSTEAD!!!!! Serious bugs exist with the new system, such as, playing MIDI through ZYNSUBFX and VSTge.(Midi record function totally not functional) No longer supports independent VST preset saving(Freezing upon loading the presets). Problems with previously supported VST's not functioning(Freezing/Non-Responsive/FX unresponsive). Mod Wheel and assignable MIDI controllers non-functioning(Includes the all mighty "Low Pass Cutoff", freezes when external controllers are assigned). LMMS freezing problems while loading VST's. New version crashes Windows 7 when running multiple MIDI keyboards and controllers. Also keeps resetting all of my VST controls (NubiLE, Ichiro Toda Synth, Agressor Synth, etc.) every time I re-open a project. Sustain Pedal no longer working with ZYNSUBFX or VSTge. Indicator lights not functioning. I've installed both 32 and 64 versions of LMMS but neither work. I actually did a factory setting restore to my computer because I thought the problem was on my end. Not true. Don't waste your time. Download LMMS 0.4.13 instead. Much better functionality and is much friendlier to the more massive VST's. SERIOUS LETDOWN!
Reviewing 1.0.0: After several experiments I found ways to circumvent too much noise in a side chained signal. But I will investigate with Audacity & Co a bit more intensive to find a reason for the existence of that crackling. For the rest... well, mostly at least it seem to work smoothly and reliable. But there is still a huge deficit - worse luck. That is too less possibilities for routing signals from track to tack (for example to create busses or 'folders'
