General Description

Murmur allows up to 8-step sequencing of two independent, parallel multimode filters. At each sequence step, the cutoff frequency and resonance value of each filter, as well as an overall gain level, can be set. The Amp Gate and Flt Gate controls determine how long within each step the gain and filter settings will remain constant, and the Curve control determines the shape of the transition from the gate period to the next beat.

The Steps and Size controls effectively set the time signature of the cycle: Size of "4th" and Steps of 3 are 3/4 time, etc. A bank of indicator lights shows the current sequence step. The Sync control determines whether Murmur synchronizes its clock to the host or to an internal clock whose speed is set by the Tempo control.

Development Notes, Known Bugs, and Limitations

Murmur is more or less derived from the Tiny God Breather plugin, which in turn was developed from the earlier plugins Breathe Beat and Filter Swamp. Unlike those plugins, it is purely deterministic, which you fascists may enjoy.

I assume there's some undesirable phase cancellation between the wet and dry signal near the cutoff frequency when the wet/dry mix is in the middle. Some day I might fix this.

Murmur has not been tested in a wide variety of VST hosts. If it doesn't work right, please let me know so I can try to fix it.

Murmur currently doesn't appear to work in Sonar 3 PE. I'm investigating.

Murmur Revision History

v0.54 - 2004/3/27 - Initial Release.
v0.55 - 2004/3/28 - Changed wet/dry label to be less confusing. v0.66 - 2004/3/31 - Added gain controls, gates, freq/reso master adjustment knobs, internal clock, swing.
