Overview
What is MFX SustainFix?
MFX SustainFix - Hold pedal polarity, continuous value thinning
In depth
A closer look at MFX SustainFix
Some keyboards send out an "All Notes Off" CC message when you lift your hands off the keyboard. Some software synths take this message as a command to turn all sound off, even if you're holding down the sustain pedal! Also, some keyboards send out CC values for the Hold Pedal other than 0 (off) and 127 (on). Now, that's allowed as part of the MIDI spec, but some lazy soft synths think otherwise and might cause your notes to hang forever, or simply ignore your pedal altogether. The MFX SustainFix VST plugin was developed to fix these problems and many more (e.g. hold pedal polarity, continuous value thinning) in SONAR or other MFX capable hosts.
