The Drop

The Drop is an analog modeled resonant filter plug-in based on classic analog synth filters, as well as completely new designs. It uses the same high quality algorithms used in circuit simulators, but optimised to run fast, and features a gorgeous fully scalable user interface. There is a huge level of detail in the models, which gives them amazing drive and tone. The original structure of the circuits is preserved in the model, as is the location and shape of all major non-linearities.


    • Pump - Audio Rate LFO

      This song uses The Drop for tremelo and panning as well as filter sweeps. The sidechain-like pumping of the synth is actually done using an LFO that can reach audio rate for dramatic buildups and breakdowns. Two copies of The Drop are used on the track, one on the synth and one on the drums.

      0:00 - Panning and filter sweeps. The LFO is used as a panning effect by using the phase offset control.

      0:30 - Pumping in time with song. The pumping here is done with a rising sawtooth LFO, no sidechain compression is used.

      0:46 - Audio rate LFO. The rate of the LFO is increased to create a ring modulation at audio rate before being swept down again for the drop.

      0:60 - LFO automatic re-sync. The LFO automatically re-syncs to the nearest bar so that it's back in time with the song.

    • One Sided Tranny - MS1 filter

      An example of using The Drop on a synth bassline and a drum beat using the MS1 circuit modelled low pass and high pass filters.

      0:00 - Dry bassline for a short time, then the low pass filter is swept into action and away again, then the highpass filter is swept into action and away again.

      0:22 - A bandpass filter is made on the bassline using both the high pass and low pass filters together.

      0:44 - The high pass is pushed into self oscillation to create interesting tones with the synth bass sound.

      1:50 - An envelope follower is used to modulate the cutoff and create an wah-wah type sound on the mix, the strong drum sounds give the filter lots of movement.

Cytomic was founded by Andrew and Emma Simper in 2007. We've been making boutique audio plugins ever since. Our software can create, change and enhance audio to help you write your best music. We model classic analog processing circuits, bringing their exact sounds to the digital world. Instead of carrying large, heavy, fragile, expensive pieces of gear around, you can have all their gorgeous sounds right there, in your computer. We use the same high quality algorithms used in circuit simulators, optimised to run fast, in real time.

All Cytomic plugins feature gorgeous, fully scalable interfaces. Having a fantastic GUI, awesome sounds and the best number crunching in the business helps, but a plugin has to be fun to use and keep you in the creative flow. Cytomic takes great care to deliver meticulously crafted plugins that are intuitive to use. Our products stand the test of time and become essential tools, used by the world's top musicians, but priced to allow everyone to create with them.

    Do you offer discounts?

    We realise very few people make much money in the music industry so we keep our price point as low as possible all the time. If you want to buy a single product and you're a student, a teacher, in a band, or work in a studio we have you covered already with our permanently low price point.

    If you have already purchased a plugin we offer a discount deal: if you spend $99 at the Cytomic store without discounts (and still own the software) you get a 30% off discount voucher to use on future purchases. For example if you buy The Glue for $99 you get a discount voucher you can to buy The Drop for $69 (or vice versa).

    Also if you purchase two or more plugins at once we offer a 15% discount off the order total.


    Which type of copy protection is used?

    Cytomic plugins use an authorisation file based copy protection system. For computers connected to the internet you can authorise directly from within the plugin. For other computers you can download an authorisation file from your Cytomic account, once you have entered a machine id.

    Each license automatically gets three authorisations per year, but it is easy to request a extra one if you need more, just let support know the circumstances and we'll help out. Once a machine is authorised there is no way to un-authorise it securely, which is why three authorisations are provided per year per license.


    Will Cytomic plugins run for me?

    Cytomic plugins support the latest versions of the Windows (Win) and Macintosh (Mac) operating systems, you just need to have an SSE2 enabled processor. Please give the trial version a go to double check everything is to your liking. The trial download is the same as the full one, and it's obligation-free.


    Can I try before I buy?

    Yes, you most certainly can!

    The trial download is the same as the full one, so give it a go since you need this to unlock the full version.


    What are the trial limits?

    The trial has full audio quality but does have a few limits, the most important two are:

    1. Automation is not supported in trial mode
    2. Settings save in your song but will not recall while in trial mode

    Because saved settings won't load with the trial it is important to authorise it BEFORE loading your saved project! To do this add a copy of the plugin to a blank project, then authorise it.


    Can I sell my license?

    Yes you can.

    For the original full price paying customer there is no charge, otherwise a 30% of the current price fee is charged. Since the original customer gets a 30% discount off their next purchase, the license transfer fee covers both this, and also the increased support load of a new customer's questions and resolution of any issues.


    Isn't analog modelling complete BS?

    The term “analog modelling” is pretty broad, anything can be termed a model of something no matter how bad the model is. A straight line can be said to model a circle under certain conditions, but when what you actually wanted was a circle and were given a straight line you wouldn't be happy! So we don't blame you if you think analog modelling plugins are a load of BS, since some of the stuff you've tried probably was.

    Cytomic models circuits by preserving the location and connection of all the critical components in it. We use the same methods used in circuit simulators, but optimised to run fast. The continuous circuit equations are discretised using MNA (Modified Nodal Analysis) and then solved for using quasi Newton-Raphson iterations to converge on a solution. Equivalent circuits of groups of linear components are pre-computed to save CPU, along with a bunch of other optimisations so that the model can run hundreds of thousands of times per second. A normal circuit simulator can take 5 minutes or more to process one second of audio, our plugins do it in a fraction of a second otherwise your CPU would be maxed out!

The Glue is a world-class plug-in

“Both the Mix and Range controls add a host of options for dialling in the compression flavour, and in practice we found this made The Glue an incredibly flexible compressor suitable not just for use on the master bus, but for individual instruments too. The Glue is a world-class plug-in and we reckon it offers amazing value.”

Computer Music December 2009

The Drop is pure magic, get it now

“The Drop is a success on so many levels, it’s a little mind-boggling that it’s priced under $100. As an emulation of analog filters The Drop is a stunning achievement. The Drop is pure magic and I’ll be using it daily for the foreseeable future. Get it now.”

Keyboard Magazine August 2013

A ‘more of everything’ compressor

“The Glue is based on the legendary SSL bus compressor and makes a mighty fine job of performing transparent bus compression. Compared to similar plug‑ins, it's more transparent but without sounding flat or boring. It's kind of a 'more of everything' compressor, and at a great price too!”

Sound on Sound November 2010

The Drop is arguably the finest filter plugin ever made

“The Drop is packed with powerful, fun and genuinely useful features, making it a fantastic plugin for anyone who uses filters creatively. Crucially, no matter how deep you choose to go with it, it always sounds absolutely superb.”
