Morphilter is a stereo multi-mode filter with LFO-driven crossfading. Morphilter produces lowpass, notch, highpass and bandpass filter responses.

It allows a continuous crossfade from one response to the next. This crossfade may be automated by an LFO. In addition, the cutoff frequencies of the left and right filters may be independently modulated by two further LFOs. All three LFOs may independently be locked to tempo or free-running.

New in v1.2

• GUI knobs default to linear operation.
• Improved sound quality.
• Boosted output level.
• Smoothed modulation.
• Revamped presets.
• Many internal improvements.
• Now uses username/authorisation code system.

New in v1.1

• A bug in the 1/f LFO waveform (wave 32, bank 2) which could cause it to drift out of range after a (very) long period of operation has been fixed.
• The 1/f LFO waveform is initialized to a random value rather than zero.
• The morph rate knob is set to minimum when the morph LFO is turned off by the RND (randomize) feature.
• The coding for the Morphilter has been rearranged and tightened to reduce the already low CPU load and memory bandwidth even further.
