Studio Recording Microphones

The Slate Digital Virtual Microphone System (VMS) combines two exceptional studio microphones—the ML-1 & ML-2—with a state-of-the-art digital processing suite that recreates the tone of classic mics and preamps. Collapsing the wall standing between audio engineers and expensive world-class recording tools, the Virtual Microphone System gives all artists access to the microphone locker of their dreams.


Meet the ML-1 Microphone

The ML-1 microphone is the centerpiece of the Virtual Microphone System. This large diaphragm mic has a shock-mounted, gold-sputtered, 6-micron capsule and a state-of-the-art FET circuit path that ensures the most linear, flat, and clean ‘blank canvas’ response.

Combined with the Virtual Microphone System, the ML-1 is capable of replicating the sound the tone of nearly two dozen iconic mics that have helped shape the sound of audio over time


Meet the ML-2 Microphone

The ML-2 microphone is a small diaphragm studio microphone that can also recreate the tone of an entire mic locker of instrument mics.

From famous dynamic mics to cardioid models of classic ribbons and even other large- and small-diaphragm favorites, the ML-2 is an incredibly versatile tool that makes recording and post-processing a breeze.




This famous German FET microphone model is known for round highs, fat mids, and huge low end. It’s a standard on kick drum and bass cab, but also sounds great on toms.


This is actually a model of a large diaphragm tube mic! It has smooth and slightly dark highs, thick mids, and big lows. Great on room mics, overheads, toms, snare, guitars, basses, and everything else!


This is a dynamic mic that became famous as a broadcasting microphone, but its present mids make it ideal for all sorts of instruments such as kick, toms, snare, guitars, bass, and more.


This is a model of a dynamic microphone that became popular in the seventies. It has a very even frequency response while remaining fat-sounding, so it can be useful on all sort of different sources – from vocals and electric guitar to kick drum.

S-57 Vintage

This model is a recreation of an early 80’s dynamic 57, perhaps one of the most famous dynamic microphones in audio history. It’s known for its punchy midrange and smooth top end, which is why it is a top choice on guitar and snare drum.

S-Custom Snare

This is a modified version of the S-57, with added curves from famous EQ’s to enhance the sound, producing the ultimate polished snare sound.

S-57 Modern

A brand new dynamic 57, this mic sounds very similar to the vintage model but with slightly smoother mids and more sizzly highs.


This is a model of a famous modern kick drum microphone. It has a classic “bouncy” midrange and fat low end.


This is the same emulated mic as the S-112 captured from inside the kick drum itself.


Another classic dynamic mic, this model is perfect on toms, kick, guitar cab, bass cab, and horns. It has thick low mids and punchy lows.

S-Custom Tom

This is a modified version of the S-421 that adds more highs and lows, and has less low mid, creating the ultimate tom sound for both rack and floor.

S-414 Normal

This is a model of one of the most famous FET large diaphragm mics. It has clear punchy mids, slightly extended highs, and a very fat low end. It’s perfect on overheads, guitar cabs, bass cabs, toms, and horns.

S-414 Dynamic

This emulation is the same as the S-414 Normal, only it has been optimized for use with the ML-2 when it’s in Dynamic mode. Use this model and the ML-2’s Dynamic mode when micing very loud sources.


This is a model of a vintage kick drum microphone. It has a crisp top, fat low mid, and warm bottom end.

S-Custom Kick

This is a modified version of the S-12 that adds more attack and punch, with less low mids and more defined lows.

S-121 Normal

This is a cardioid model of the classic ribbon mic, and like the real thing, it has fat lows and slightly dark highs, making it perfect on horns, strings, room mics, guitar cabs, and overheads.

S-121 Dynamic

This emulation is the same source microphone as the S-121 Normal, only it has been optimized for use with the ML-2 when it’s in Dynamic mode. Use this model and the ML-2’s Dynamic mode when micing very loud sources.


This is a model of a famous small diaphragm tube mic. It’s bright but not harsh, with a smooth midrange and flat low end. It’s ideal for drum overheads, acoustic guitars, and string instruments.


This is a model of a famous small diaphragm condenser that is smooth and clear, with a beautiful high end. It’s great on snare, overheads, hi hat, toms, and guitar cabs if paired with one of the dynamic models.

Latency Free Processing

The Virtual Microphone System software consists of the Classic Tubes microphone module, which contains eight classic tube microphone models, the FG-73 British discrete preamp module, and the FG-76 German tube preamp module. None of these processing blocks add any latency to the audio signal, so if you use a low latency interface with VMS you can track through the VMS software without any audible monitoring delay.

To accomplish this, we recommend a Thunderbolt or fast USB interface, recording at 96khz with the lowest buffer size possible. The combination of the 96khz sampling rate and low buffer size ensures the lowest possible latency.
