Here is how to start with Make Noise, Intellijel, Doepfer, TipTop Audio and other current modular makers. - Author: unknowndivide staff - Tags: Gear, Music *Unknowndivide may earn a commission from purchases made through links in this post.* A modular synthesizer is a music instrument you assemble from separate modules, then wire together with patch cables. The dominant format today is Eurorack, a standard for panel height and power that most new makers build to. This guide covers what a first kit actually needs, how to start without guessing, and which current makers to know. If you are still deciding whether modular is the right next step, our guide to the [best synthesizers for beginners](https://www.unknowndivide.com/best-synthesizers-for-beginners/) covers complete keyboards and desktop instruments first. ## What Eurorack means Eurorack modules share a 3U panel height and a power bus that typically supplies plus and minus 12 volts, with many cases also offering 5 volts. Width is measured in horizontal pitch, or HP. A small starter case is often around 84 to 104 HP. Depth varies by case, so shallow skiffs and deeper performance cases suit different modules. Patch cables carry audio and control voltage, or CV, between modules. Musical Instrument Digital Interface, or MIDI, and Universal Serial Bus, or USB, appear on many modern cases and semi-modular instruments so a keyboard or computer can talk to the system. ## What a first kit needs There is no single correct shopping list, but a playable starter voice usually includes these parts. **Case and power.** Buy a case with a built-in power supply and bus boards. Empty rails without power are not a kit. TipTop Audio's [Happy Ending Kit](https://tiptopaudio.com/happyendingkit/?ref=unknowndivide.com) bundles Z-Rails, Z-Ears for tabletop or rack mounting, a 4 HP microZEUS power supply with two flying bus boards, and a universal adapter. Make Noise's [2 Zone Skiff](https://www.makenoisemusic.com/cases/2-zone-skiff/?ref=unknowndivide.com) is a 3U, 104 HP aluminum skiff with a two-zone bus board and rated power on the plus 12, minus 12 and plus 5 volt rails. Intellijel builds 4U Palette cases in 62 HP and 104 HP sizes with integrated power and utilities such as buffered multiples and MIDI jacks, plus deeper 7U performance cases. **Sound source.** A voltage-controlled oscillator, or VCO, makes the raw tone. Some modules combine several oscillators or add wavetables. Semi-modular desktops such as Make Noise's 0-COAST put a triangle-core analog VCO and related circuits in one box so you can play before you fill a case. **Filter and dynamics.** A voltage-controlled filter, or VCF, shapes harmonics. A voltage-controlled amplifier, or VCA, and related low-pass gate circuits control loudness. Envelopes create attack, decay, sustain and release shapes that open the filter or VCA when you play a note. A low-frequency oscillator, or LFO, adds slower motion for vibrato, filter sweeps and rhythmic modulation. **Mixing, utilities and effects.** A small mixer combines voices or submixes. Utilities such as attenuators, multiples, slew and sample-and-hold keep patches tidy. Effects modules add delay, reverb or other processing when you are ready. Clock and modulation hubs keep a growing system in time. **Cables.** Starter systems often ship with a short pack of 3.5 millimeter patch cables. You will want more lengths soon. Keep a mix of short cables for neighbors and longer ones for cross-case patches. ## Semi-modular on-ramps If a blank case feels intimidating, start with a complete voice that already speaks Eurorack levels, then add modules later. Make Noise's [0-COAST](https://www.makenoisemusic.com/synthesizers/0-coast/?ref=unknowndivide.com) is a single-voice patchable synthesizer in a small steel enclosure. The company describes it as "no coast synthesis," borrowing ideas from both East Coast and West Coast traditions without belonging to either. It runs with or without patch cables, includes MIDI to CV and gate, a MIDI arpeggiator, an overtone and multiply timbral section, a transistor-based low-pass gate, an external audio input, and headphone and line outputs. It ships with power, MIDI and patch adapters, and speaks Eurorack signal levels. Intellijel's [Cascadia](https://intellijel.com/shop/voice/cascadia/?ref=unknowndivide.com) is a larger semi-modular playground in a laptop-sized footprint. It packs dual precision analog VCOs, a multimode filter, wavefolder, dual envelopes, VCA paths, utilities, MIDI over DIN and USB, balanced quarter-inch audio and a pedal loop. Cascadia ships with patch cables, a USB cable and a power supply, and uses Eurorack-compatible signal levels. ## Makers to know right now [**Make Noise**](https://www.makenoisemusic.com/?ref=unknowndivide.com) (Asheville, North Carolina) builds systems, controllers, modules and cases. Beyond the 0-COAST and 2 Zone Skiff, Make Noise sells complete systems such as the New Universal Skiff System in a 104 HP skiff with USB-C MIDI support. MATHS remains a widely used analog function generator for envelopes, LFOs, slew and voltage mixing in 20 HP. [**Doepfer**](https://www.doepfer.de/a100%5Fe.htm?ref=unknowndivide.com) defined the A-100 Eurorack format many other makers follow. The company still publishes Basic System packages for beginners, mounted in powered frames such as the A-100G6 or A-100P6, with patch cables included. Those systems mix classic building blocks: VCOs, ADSR envelope generators, LFOs and related modules, so you can learn patching on a coherent set of panels. [**TipTop Audio**](https://tiptopaudio.com/?ref=unknowndivide.com) focuses on power, rails and practical starter hardware. The Happy Ending Kit is the company's documented way to stand up a small powered Eurorack frame before you choose voices. TipTop also makes module lines and Buchla format products for builders who expand later. [**Intellijel**](https://intellijel.com/?ref=unknowndivide.com) (Canada) covers desktop instruments, Eurorack modules and cases. Palette cases put power and studio I/O in a shallow 4U format; Gen-2 7U performance cases add deeper module clearance, MIDI and multiple quarter-inch jacks. Cascadia is the flagship semi-modular entry point. [**ALM Busy Circuits**](https://busycircuits.com/?ref=unknowndivide.com) designs compact Eurorack modules and cases. Pamela's PRO Workout is an 8-output clocked modulation source synced to a BPM-based master clock, with editable waveforms, rhythmic and melodic patterns, CV control and optional expanders for MIDI and DIN sync. It replaces earlier Pamela's Workout generations while keeping a small form factor. [**Noise Engineering**](https://noiseengineering.us/?ref=unknowndivide.com) builds digital and analog Eurorack modules for voice, rhythm and sequencing, including the Legio line with swappable firmwares. [**4ms Company**](https://4mscompany.com/?ref=unknowndivide.com) makes Eurorack modules, power solutions, faceplates, Pods and kits. Pods are small powered enclosures for carrying a few modules outside a full case, which suits pedals-style setups and travel. [**Verbos Electronics**](https://www.verboselectronics.com/?ref=unknowndivide.com) designs analog Eurorack modules and larger pre-planned configurations for builders who want a coherent voice stack. [**Expert Sleepers**](https://www.expert-sleepers.co.uk/?ref=unknowndivide.com) specializes in Eurorack modules that bridge computers and hardware, including the Disting mk4 and Disting NT multi-function modules, Forever audio freeze voices, FH-2 MIDI and CV tools, and USB and ADAT audio interfaces such as the ES-8, ES-9 and ES-10\. If your studio centers on a digital audio workstation, these modules are often the glue. [**Endorphin.es**](https://www.endorphin.es/?ref=unknowndivide.com) offers Eurorack modules, pedals, desktop instruments and compact powered cases aimed at performance racks. ## How to build without painting yourself into a corner **Start powered, then add voice.** Get rails and a supply first, or buy a semi-modular that already makes sound. Empty decorative cases waste money and stall learning. **Watch power and depth.** Add up module current draw against the case ratings on the plus 12, minus 12 and plus 5 volt rails. Check maximum module depth against the skiff or performance case you chose. Make Noise publishes separate depth figures over the bus board for the 2 Zone Skiff; Intellijel publishes Palette and 7U depths on each case page. **Leave HP free.** Fill maybe two thirds of a first case. Blank panels keep airflow and leave room for the module you discover you actually need after a month of patching. **Learn one voice thoroughly.** A VCO into a filter into a VCA, opened by an envelope and stirred by an LFO, teaches more than a case stuffed with unconnected specialty modules. MATHS, Pamela's PRO Workout or a Disting can wait until the basic voice feels musical. **Plan studio I/O early.** Balanced outputs, headphone amps and MIDI on the case or semi-modular save adapters later.

For gift and accessory ideas around that wider setup, see [best gifts for producers and synth heads](https://www.unknowndivide.com/best-gifts-for-producers-synth-heads-2026/). For a self-contained hybrid that many producers use before they open a case, the [Arturia MicroFreak](https://www.unknowndivide.com/arturia-microfreak-hybrid-synthesizer/) remains a strong desktop reference point. Build slowly, patch daily, and let the modules you reach for most often decide the next purchase. That is how a kit becomes an instrument. **Shop modular starter gear** [Make Noise 0-COAST](https://www.amazon.com/dp/B01I03GXAO?tag=unknowndivi02-20&ref=unknowndivide.com) [TipTop Audio Happy Ending Kit (Black)](https://www.amazon.com/dp/B07PGBYYLN?tag=unknowndivi02-20&ref=unknowndivide.com) [TipTop Audio Happy Ending Kit (Silver)](https://www.amazon.com/dp/B07PLLNQSX?tag=unknowndivi02-20&ref=unknowndivide.com) [Synthrotek Eurorack patch cables, 6-pack](https://www.amazon.com/dp/B09YYZC8VR?tag=unknowndivi02-20&ref=unknowndivide.com) [Make Noise 2 Zone Skiff (maker)](https://www.makenoisemusic.com/cases/2-zone-skiff/?ref=unknowndivide.com) [TipTop Happy Ending Kit (maker)](https://tiptopaudio.com/happyendingkit/?ref=unknowndivide.com) [Intellijel Cascadia (maker)](https://intellijel.com/shop/voice/cascadia/?ref=unknowndivide.com)
