Modbap Modular’s Quad Performance Effects Eurorack Module
2025
Per4mer a quad performance effects unit
Per4mer is a quad performance FX module consisting of a delay, reverb, glitch, and tape stop effects triggered by the four dedicated arcade buttons which can be manually operated or triggered from external gate inputs. Each effect has a set of FX parameters that can be controlled using the four rotary knobs or by the CV inputs. Compression and color processing effects are featured along with sidechain and tap tempo options. The external sidechain and clock can be connected to interface with other gear. Per4mer packs a punch in a 14HP stereo FX eurorack module form and is inspired by beatmaker/DJ performance styles. Per4mer makes quick, fun, and easy work of engaging and performing with smooth no click action arcade buttons.

Modbap Modular enters the Eurorack market with powerful Per4mer quad performance effects. The basic principle behind Per4mer is immediately apparent in its easy-to-follow front panel, packing a creative knockout punch in a compact (14HP) stereo effects-enabling Eurorack module form factor — feed in an audio input to then 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 uniquely unconventional beats and melodies.
Per4mer Features
- 4 no-click 24mm mini arcade buttons (life cycle rated at 10 million button presses)
- 4 knobs to control 4 parameters per effect
- 4 performance effects (Delay, Reverb, Glitch & Tape Stop)
- 2 processing effects (Color and Compressor)
- 4 fixed color presets (Classic (12bit), LoFi (8 Bit), Saturation, and Wax)
- Sidechain input
- Side-chain detection– (activate side-chaining via side-chain input, clock input, or tap tempo)
- Clock input
- Tap tempo
- CV control over knobs
- Gate inputs to trigger the arcade buttons
- Stereo input and output
Per4mer puts a Doppler-style DELAY, lush REVERB, GLITCH (beat repeat), and TAPE STOP effects easily at anyone’s fingertips for triggering via four dedicated translucent mini-arcade buttons — buttons that can be manually operated or triggered from the four external gate inputs.
Each effect has a set of four effects parameters that can be controlled using the four (FX 1, FX 2, FX 3, and FX 4) rotary knobs or by the four CV (control voltage) inputs. COMP (compression) with SIDE CHAIN input and COLOR processing effects are also available, along with CLOCK input and TAP tempo options. Obviously, the external side chain and clock can be connected to interface with other modular and electronic music gear.
“Per4mer acts like a bridge between hip-hop and Eurorack.” So says Modbap Modular Designer and Founder Corry Banks. As a writer, emcee, producer, hip-hop artist (Phashara), and IT pro, he should surely know! “It packs in concepts familiar to lo-fi and beat-making circles, but it brings something fresh to Eurorack,” continues Corry Banks, before adding: “I think Per4mer will be a great entry point to modular synthesis for the modular-curious beat-maker — throw it into a small pod and use it like a standalone performance effects unit or rack it up with other modules to liven things up a bit.”
But best of all, Per4mer’s four performance effects — influencing its notable nomenclature, clearly — can be momentarily engaged or latched individually or simultaneously. Each effect has four tweak-able parameters associated with the four rotary knobs, duly designed for facilitating live improvisation with endless one-off, on-the-fly sounds and rhythmic dynamics.
All audio inputs (INPUT L and INPUT R) are provided as mono connections, paired for stereo. Subsequently, Per4mer not only delivers a series of excellent effects and sound design possibilities, but it also allows the creative, classic, tried-and-tested techniques used by beat-makers and DJs to be applied to the wonderful world of Eurorack modular, especially enhanced by manual performance.
Digging deeper, the compressor allows for control over four compression (Threshold, Ratio, Attack, and Release) parameters via the four rotary knobs. Catering perfectly to those users craving the classic ducking sound of side chaining, the compressor also features selectable side chain detection that allows side chain activation via ‘sidechain input’, ‘audio input’, ‘clock input’, or ‘tap tempo’.
The COLOR processor features four color presets bringing texture and character to the signal path, pre effects — namely, Classic (12-bit), LoFi (8-bit), Saturation, and Wax (vinyl simulation). Such presets can be used in combination with the performance effects and compressor for a more characterful result. Reasons Corry Banks, eventually ending on a high note: “The COLOR processor is the special sauce built into Per4mer. It adds so much mojo and attitude. I lose time just enjoying processing audio through it and creating soundscapes to sample. Per4mer is a dope sound design tool as much as it is a dope performance effects module!”
About Modbap Modular
Modbap Modular is a line of eurorack modular synthesizers and electronic music instruments by Beatppl. Founded by Corry Banks (Bboytech), Modbap Modular was born from the Modbap Movement with a simple mission to dev tools for beat-driven hip-hop leaning modular artists. It is our goal to develop eurorack modules from the beatmaker’s perspective while adding value for music makers of all genres. MODBAP is the fusion of modular synthesis and boom-bap (or any form of hip-hop) music production. The term was created by Banks as a denotation of his experiments with modular synthesis and boom-bap music production. From that point forward, a movement was born where like-minded creatives built a community around the idea of Modbap. Modbap Modular is the result of that movement in synthesizer design space where we’d previously not existed.
Corry Banks coined the term “Modbap”. As the founder of both BBoyTechReport and Beatppl, Banks focuses on assuring the voice of hip-hop is present in music technology. Banks’ passion is to bridge the gap between hip-hop and modular synthesis

Hello everyone. We’ve been on a Budhist retreat in a cave on the dark side of the Moon for the last two years and literally just returned to Earth today. Did we miss anything whilst we were gone? Anything exciting happen?
Signal Sounds Roundup May 2022
Now that we’re back, fully enlightened and settled in again we’ll endevour to make these mails more regular, keeping it short and sweet and hopefully giving you the best new synths and modules and a few interesting titbits we’ve seen on our travels over the internetz.
Superbooth
Superbooth is the primary source of excitement in the modular and synth world at the moment, taking place in Berlin on Thursday 12th May through to Saturday. Both myself and Aleks will be bothering every one of the 100+ companies exhibiting there to get the lowdown on what new delights they have for us. We’ll do a round up afterwards but the best place to see regular updates would be on our Instagram page.
Ben DivKid continued his mission to bring interesting and affordable modules to the world, His last was with Stead State Fate (the wildly successful RNDStep) and this time around he returns to his first partners, Befacco, to bring us the Stereo Strip.
It’s outrageously good value given that some companies charge more than £200 just for an Audio In and Out module – this one offers that feature (Eurorack or standard Line level, separately selectable for both in and out) PLUS a very high quality Stereo panner and EQ circuit. It’s very funky and not very chunky given that it’s only 6hp. The usual high quality video from Ben (above) is here if you need more convincing.
Look Mum No Computer has been a big figure on YouTube for a long time now and has a repuation for unusual large format 5U modular synths but has now taken those designs and succesfully transplanted them into Eurorack format. The first (of many) module is an all analogue Oscialltor with built in visual Tuner (something rarely seen and since the demise of TipTop’s Z3000…almost impossible to find) and other performance oriented features like Octave Switches. Almost sold out already, move quick if you need to get one.
Non Eurorack Stuff – still lots of interesting stuff happening outside of your rack, look out for some really, really good stuff from Polyend, Moog and Korg in particular and of course the new Dave Smith/Oberheim release, the OB-B8 which we’ll be elbowing people out of the way to get a shot of at the show.
Signal Sounds Shop – if you’ve communicated with us over email in the last year you’ll have heard us moan about how long it’s taken to get the new place fully up and running after out move, however…..we have some final touches being applied to the showroom next week and after that we’ll be in a much better place to make a really inviting and comfortable place to enjoy synths and geek out in. There’s all the Eurorack you can eat plus a cross section of vintage synths, drum machines, mixers and effects to mess with. And a Beer Fridge.
Just a few bits that are in stock now that are worth mentioning
This little lot have show up over the last week or two:

Transit Eurorack Mixing – The All-Analog Stereo Signal Processor with Dual Mono Channel Lanes and Ducking Input
2025
Looking for an all-analog stereo signal processor with dual mono channel lanes? Look no further than Transit Eurorack Mixing! This amazing eurorack module has two channels of audio with its own input gain control, mute button, and ducking input.
The Ducking input on each channel operates like traditional side-chaining on a compressor, allowing you to modulate the gain reduction of the audio with an external signal. Whether you’re looking to add some depth to your sound or create interesting effects, Transit is sure to be a valuable addition to your eurorack case!
Transit Eurorack Mixing
The Transit is a 6HP mixer with two stereo channels that is designed for use in Eurorack systems. It features a variety of mixing and performance-oriented functions, such as gain staging, ducking, and mutes.
The Transit is compact and easy to use, making it a great choice for small Eurorack systems. However, it is also capable of being used in larger systems, thanks to its robust construction and versatile feature set.
Mixer and More with A Small Footprint
All in all, Transit is a rather full features compact 6hp dual stereo channel lane eurorack formatted mixer that offers easy signal mixing, gain staging, ducking, and performance-oriented mutes.
Transit is just as at home in a small eurorack system as one Transit or several would be in a larger system. The build quality is excellent with a sturdy aluminum chassis and clear LED indicators. The audio quality is very good with low noise and distortion. The controls are well laid out and easy to use.
Eurorack Module Transit
The Eurorack module Transit is a versatile tool for processing audio signals. It features two audio stereo (dual mono) channel lanes with an all-analog signal path. Each stereo channel lane has its own input gain control, mute button, and ducking input.
Ducking Input
The Ducking input on each channel operates like traditional side-chaining on a compressor where an input signal, CV, or Trigger input (i.e. LFO, Clock, Gate) modulates the gain reduction of the audio. This allows the Transit to be used for a wide range of applications, from simple level attenuation to complex audio processing.
Dedicated Output Section
In addition, the Transit includes a dedicated output section with level controls and an output mixer. This gives the user complete control over the processed signal, making the Transit an ideal solution for anyone looking for a high-quality audio processing tool.
Transit offers two different audio output options, each controlled by its own volume knob. The main stereo output is perfect for speakers or other external sound systems, while the 3.5mm headphone output is ideal for personal listening.
The headphone output is located on the front of the Transit for easy access, and the level control knob allows you to adjust the volume to your preferences.
Connect to the World and Eurorack Case
The Transit comes equipped with everything you need to get started making great-sounding music right away. Its all-analog signal path starts with a 3.5mm headphone jack, which has its own independent volume control knob.
From there, the signal travels to left and right stereo output, where it is controlled by a MASTER volume knob.
The Transit also features a built-in metronome, which is perfect for helping you keep time while you practice or play.
Controlled LEDs
The level of each stereo channel is indicated by LEDs that can be controlled digitally. The LEDs will illuminate in white, blue, or pink to show the level. When the mute is engaged, the LEDs will turn red.
There are also LEDs for the master and headphone levels that use the same color scheme. This allows for easy level indication without having to look at the actual levels. The colors make it easy to see at a glance which channels are muted or at what level they are set.
As anyone who’s ever dealt with a finicky sound system knows, level indicators are essential for getting the perfect sound. That’s why the Transit is equipped with digitally-controlled LEDs (Light-Emitting Diodes) for each stereo channel lane. The LEDs use a white, blue, and pink color scheme to indicate level, making it easy to get the perfect sound.
And if you need to mute the sound completely, the Transit has you covered there too. The CH1 MUTE and/or CH2 MUTE buttons illuminate in red, so you can be sure that the sound is completely off. Meanwhile, MASTER and PHONES levels also have their own LEDs for level indication.
