SKU: MM-PER4-01 Categories: , Tags: ,


Per4mer is a 14hp eurorack formatted quad performance effects unit. Inspired by time-honored DJ effects processing boxes, Per4mer allows for a hands-on and CV / Gate controlled eurorack effects performance interaction.  Whether momentarily engaging or latching FX, Per4mer offers an unrivaled and fun experience.

The basic principle of Per4mer is to feed in an audio input and to trigger on-the-fly effects, bringing DJ style live improvisation to a modular environment. Effects can be triggered simultaneously or individually where an inspiring effect palette combines to generate unique creative beats and melodies.

Per4mer includes 4 performance effects (Delay, Reverb, Glitch, Tape Stop) and 2 processing effects (Color processor & Compressor). Each of the 4 performance effects has its own set of 4 parameters controlled by the 4 knobs or CV inputs. Effects can be used simultaneously or individually allowing for a vast variety of creative effects combinations.

The Color processor allows for engaging any of the 4 coloration presets – Classic (12bit), LoFi (8 Bit), Saturation, and Wax. Combine any one of these color presets with the onboard Compressor and Side-Chain input to instantly transform any audio signal’s mood and vibe.

Engaging the Reverb along with the “12-bit classic” color option gives an incredibly lush lo-fi reverb sound while disengaging the color option allows the reverb to remain just as beautifully lush and hi-fi. The potential is nearly limitless.

Per4mer’s ‘Glitch’ effect is inspired by classic beat repeat and looper effects offering 4 controls – Wet/Dry (sound on sound), Loop size, Pitch, and reverse. Conversely, the Tape Stop effect allows for the perfect punctuation of any audio signal.

  1. YNOT

    Per4mer has become a staple in my set-up!! The ModBap sound is being crafted by its own hardware now!! Blast off!!!

  2. Synthesaurio

    This is an awesome performance module, the big arcade buttons are an excellent way to interact with a modular system. I use it for ambient and house and works great for both!

    Watched the Divkid review of this module before it’s release and could not wait to get it. It has been months since it arrived in the mail and it has been a part of every patch since! Put some clocked LFOs in the Knob CV inputs and mess with the buttons and you’ll see why it’s a permanent fixture in so many artists setups. Can’t wait to see what’s next from ModBap Modular!

    I received my unit in the mail today and after a slight learning curve on the set-up i’ve successfully installed my Per4mer and it does not disappoint! I will literally NEVER get bored of this fx board or module. the sounds you can get out of it is exactly why I wanted it! its punchy and gritty but refined. Its a PERFECT edition and pairs well with just about anything i’ve thrown at it! . This is something I will NEVER sell and is a welcomed piece of gear to my studio and cant wait for all the days and hours that will be spent with this. Modbap is welcomed with open arms to the hiphop community and rightiful so. This piece is gonna be sought after like vintage gear to many of producers and the ones who sleep on it, will regret. Yes, I struggled with the price at first, ain’t gonna front, but after having it in hand, you see where that dough goes, its a solid built unit. i’d throw the $400 at em again w/o even thinking twice. Thats my 2 cents about it. Hope it helps some of you on the fence about it.

    The per4mer is now a fix part of my master chain and I think it wont’ ever leave my live case! Especially now, that it saves the last state, and with dry/wet on the colors! Firmware 1.1 took it to even another level! Now I can tweak and dial in the sidechain compression in my studio and recall it on stage exactly the way it should sound. Glitch and Tapestop are so good for little fills every now and then, and it livens up any live performance by a lot!
