de la mancha says that unstable likes to mess around with your audio pitch, with 3 subtle pitch modulation modes to simulate the unpredictable but lovable pitch instability of an old tape machine or an analogue synth - it doesn't only do subtle though, you can also put it in 'insane' mode if you'd rather just FSU...
Pricing and Availability:
unstable used to be a payware plug-in, but is now free to download. However, if you like and use any de la mancha plugins, please consider donating to Cancer Research UK in order to help care for and find a cure for cancer sufferers.
