Here’s a test composition using another patch I created for Curve titled Auto Octave Filter Sweep by AudioCookbook. On this patch I used two of the LFOs. The first one I setup to alternate between the octaves with a square wave, and the second I used with a sign wave to modulate the cutoff frequency on the filter configured with a 24dB low pass filter. On the second LFO I used the fixed rate that ranges from 0.020 hertz all the way up to 5.24 kilohertz. I mapped a MIDI controller to the LFO speed and adjusted it over the full range during the sequence. I also made adjustment to the cutoff frequency, resonance, and envelopes during the 5:20 minute recording.
