Synthrotek has introduced the MST Eurorack Voltage Controlled Low Pass Filter – a collaboration with synth pioneer George Mattson.
The MST Low Pass Filter is a precision analog dual-slope output 2 & 4 pole filter. It offers simultaneous -12 DB and -24 DB outputs, with CV control over all parameters. It can also be used as a 1V/O sine wave oscillator.
Features:
- Manual control of cutoff frequency
- Manual Control of Resonance (Q)
- 1V/O input for clean sine wave output
- CV Frequency input w/ attenuator
- Resonance CV input w/ attenuator
- Audio input
- Simultaneous -12 db and -24 db/octave outputs
Here’s the official video intro:
Specifications:
- Current draw: V+ max 23.5mA, V- max 15.5mA
- Width: 6HP Depth: 3.5cm (1.75 in)
The MST Eurorack Voltage Controlled Low Pass Filter is available as a DIY kit for US $99.99 and assembled for US $164.99.
Nice sounding filter.
The LFO kit is cool. Always need more LFOs.
I am no stranger to making kits, but $100 is steep. Also the instructions are incorrect they don’t answer emails and so I took my unusable piece of metal, desoldered all the parts and used it on my Erica synths kit which is an 84 HP bundle for under $200 and has a MIDI-CV, TWO VCOs, TWO EGs, one VCF, one LFO, one VCA, and one Output.
I did successfully build the MST Unity Gain Mixer by SynthRotek so I’m not completely writing off the company. I personally will never buy their kits again though.
Here is the video I made of the Unity Gain Mixer build if you’re interested in what exactly comes with the kit and the procedure to build it as well as the quality (FYI: the manual said it’s used to mix triggers and CV, not Audio signals. At the end of the video you can see me mixing 9 different audio signals just fine):
