Manufacturer's description

This book is a clear, structured introduction to modular synthesis (synthesis in the modular environment), focused on helping you understand what’s actually happening. Whether you are brand new to modular or looking to solidify your fundamentals, this handbook builds a strong conceptual foundation you can rely on in any system.

What You’ll Learn

Core Building Blocks of Modular

Step by step, the book covers the essential concepts behind synthesis, including:

  • Control Voltage (CV)
  • Oscillators and LFOs/Modulation
  • Envelopes, VCAs, and filters
  • Pitch, 1V/Oct, and frequency
  • Clocks, sequencers, logic, and randomness
  • Mixing, attenuation, offsets, and signal flow

Each topic is explained clearly, visually, and in plain language.

While this is a fundamentals book, it’s firmly rooted in real-world patching.

Toward the later chapters, you’ll find practical patch examples that bring the concepts together, including:

  • Basic voices and subtractive synthesis
  • FM, AM, and oscillator sync
  • Drum sounds
  • Generative techniques

These patches aren’t meant to be recipes to memorize, they’re demonstrations of how the fundamentals interact.

Why This Book Helps You

  • Build a solid foundation — understand synthesis and modular from the ground up
  • Patch with intention — know why something works, not just that it works
  • Transfer knowledge anywhere — the concepts apply to Eurorack, software modular, and even non-modular synths

Who It’s For

  • Musicians who want to understand synthesis from the ground up
  • Beginners exploring modular synthesis
  • Modular users who want a stronger grasp of the fundamentals
  • Producers and sound designers curious about synthesis and modular
  • Educators and students learning synthesis conceptually
  • Anyone who prefers clear explanations over guesswork

How much is my shipping?

Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK, 'next working day' shipping is free if the order value is over £150, and £5 otherwise. We can also ship on a 'next working day before 12pm' service, which costs £6 for orders over £150 and £7.50 for orders under £150.

Shipping to mainland EU typically costs between £7 and £20, depending on the shipping method and the size and weight of the order.

Do you ship to my country?

Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.

Shipping methods

We use a combination of DPD, Royal Mail and Parcelforce for the UK, and for international orders it's either DHL, FedEx, UPS, Royal Mail or Parcelforce depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.

Dispatch times

For UK orders, we aim to dispatch the same working day if we get the order before 16:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.

For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes the couriers may come to collect a little earlier than scheduled which would also push an order into the next day.

Saturday/Sunday shipping

If you're in the UK and you order before 16:00 on a Friday then we can send something for a Saturday or Sunday delivery with DPD. This is FREE for order values over £350, £5 for order values between £75 and £250, and £7 for order values under £75. (NB: this applies to UK mainland addresses only). Please note that any orders placed after 16:00 on a Friday will ship on the Monday.

International shipping times

Since April 2020, the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer. There is absolutely nothing we can do about this, unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.

Pre-orders

If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.

If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
