MST VC Low Pass Filter 1v/o Tuning Instructions
Things you will need:
- 1v/o cv source (midi-cv with a keyboard, oscillator with a Hz readout)
- The MST VC Low Pass Filter
- Patch cables
- Chromatic tuner (we use Pitchlab Pro, its free for Android and IOS)
- Small flathead screwdriver
Patch Setup:
- Plug your 1v/o source into the 1v/o jack in the MST VC Low Pass Filter
- Plug the -24db output of the filter to an amp or speakers, something where you can hear it.
- Turn All Knobs to the Full CCW position.
Tuning Instructions:
- Set your 1v/o source to 0v, which we will call C1.
- Turn the Resonance knob all the way CW.
- Slowly turn the Cutoff knob CW until you can hear the Filter self oscillating, and keep turning until the pitch reads ~32.7 Hz, C1.
- Set your 1v/o source to 1v, which will be C2.
- Flip the Filter over and adjust the trim pot until the pitch is ~65.4 Hz, C2.
- Set your 1v/o source to 2v, and check that the filter is now at C3, 130.8Hz.
