BFM or Big F*ing Meters is a macOS, Windows, and soon to be iOS compatible Metering plug-in designed exactly how the name sounds... really f*ing big. With the main goal of readability we wanted to bring a meter that you can see from across the studio and keep your records clip-free. BFM currently offers 6 Modes with RMS, LUFs, Peak, and Peak Hold values, to give you a variety of views to keep your signal under control. The Text, Bars, Waves, VU Meters, Spectrum, & Time let you decide how you want to keep track of your signal with multiple fonts/formats to view them in. Text gives you a quick look at just the values easy to see from across the room. This view offers the most values with RMS, Peak, Peak Hold, and LUFs (Short Term & Momentary with Maximum values and LUFS range) values available. Controllable sensitivity & peak hold time for all pages. Reset Peak Hold with a click off the value. Bar offers a more traditional meter for seeing the range of values showing RMS, Peak, Peak Hold, and LUFS. Correlation & Balance meters included to set your stereo image and phase response. Peak Hold resets on value click. Sensitivity changes on bar click. LUFS readings select on click. Included reference points for -24 (EBU), -16 (Apple Music), & -7 as a suggested maximum for most genres. Wave view gives you a look at your waveform after your channel effects with the ability to quickly mark in dB where you want to see your signals peak. To freeze click the waveform. To reset Peak Hold click the value. VU Meter Designed for a quick look at your overall levels. Featuring controllable Attack, Release, Minimum, and Maximum value control. Left/Right, Mid/Side, PPM, and LUFS options available. Click VU to enter dark mode. Spectrum is a simplified frequency spectrum view with 3 quality modes. Great for getting an overall look at where your frequencies are when mixing or editing. Tap to freeze and inspect. There is also the PEAK value displayed on this page. To reset Peak Hold click the value.

The MF-102S Ring Modulator is a re-invention of Moog Music’s classic Moogerfooger MF-102 analog effects pedal. The MF-102 Ring Modulator, introduced in 1998, contained three complete modular functions: a Ring Modulator, a voltage-controlled Carrier Oscillator, and a voltage-controlled dual-waveform Low Frequency Oscillator (LFO). Designed by Bob Moog and his engineering team, the MF-102 was a direct descendant of the original Moog modular synthesizers, adapted to process, modulate, and play with inputs ranging from guitar, voice, and synthesizer to any imaginable audio source. The MF-102 Ring Modulator has been meticulously recreated as the MF-102S, capturing not only the spaced-out, retro-futuristic sound of the original, but also the organic way in which the parameters interact to create a musical playing experience. The MF-102S is an AUv3 effects plug-in that requires a compatible host or DAW to function.
