+- All effect parameters can be controlled via the GUI, or by Sysex messages (f.ex. turn effect on/off, modify effect parameters) +- Complete synth state (fx-parameters, samples etc) is saved together with MusE project, and restored later when loaded +- Samples automatically resampled when loaded (if needed) + +That's all folks! + +------------- +Known issues: +------------- +- Not the prettiest gui in the world +- All samples are read directly into memory (no caching) +- Some obscure LADSPA-effects make SimpleSynth segfault +- More... + +------------- +Future plans: +------------- +- Fix all
