This morning, I woke up to a post on the iPad Musician Facebook page, from Bram Bos. He was giving away some promo codes for his drum machine app, Ruismaker. As cool as that was, it was his name alone that caught my attention. I asked him if this was the same Bram Bos from the Hammerhead days, to which his reply was, “the very same”. That was exciting!

Let’s set the Wayback Machine to, say… mid 90’s. For me, this was a turning point in my musical journey. I had just left a local cover band and began to focus my energies on becoming a father for the first time. I knew my free time would be taken up with changing diapers and making sure to keep a miniature version of me from any harm. I had recently purchased my first home PC computer and the internet was still in its infancy. Soon after, I was exploring the idea of using this computer to make music. Over the course of seven years, I began teaching myself how to use the various programs that existed at that time. One day, I happened across two programs. One was Little Drummer Boy, a drum synth; and the other was Hammerhead. LDB could create pretty cool drum sounds, allowing the user to create any tone he wanted by manipulating envelopes and oscillators. Hammerhead was a fantastic sounding drum machine. Soon after, I discovered a sequencing program called Moonfish, a three track sequencer that allowed the user to create drums and simple synth sounds. Eventually, Taureg came out, a more advanced program that had all kinds of options to let the user create and effect sequences, thus turning out multi-tracked songs. I was a fan right away and purchased the pro version($20USD). Money well spent in my book. I cut my teeth on that program, learning how to use a computer to make music. As time went on, I moved on to more sophisticated programs, then ultimately, iOS devices and apps.

Up until this morning, I had not heard Bram’s name, so it was a pleasant surprise to see he started making apps. Ladies and gentlemen, I give you Ruismaker. Here is the App Store description of the app:


What the reviews say:

“All of this comes together in a vision that’s really playable […] this is another excellent choice for the iPad.” – CreateDigitalMusic

“Small, compact and easy to use, Ruismaker is both inexpensive and a perfectly credible choice if you are after solid drum synth sounds.” – MusicAppBlog

“Ruismaker also has a very intuitive and friendly interface making the job of actually creating drum patterns a pleasure.” – The SoundTestRoom

The first drum synthesizer plugin for iOS. Works conveniently inside your sequencer and Audio Unit Instrument hosts so you can focus on making electronic music without app switching and screen juggling like before.

*IMPORTANT* Audio Units are plug-ins that need a compatible host app to work. Ruismaker has been tested to work beautifully with Steinberg Cubasis, Apple Garageband, Modstep, AUM and MultitrackStudio.

– Audio Unit Instrument: making music on iOS doesn’t get more convenient
– Each sound is modeled using authentic analog and FM algorithms;
– Comes with dozens of unique customizable models, more to come
– Does not use any samples; all sounds are synthesized in realtime, on the fly
– Emulates analog components, introducing subtle, natural fluctuations in the sound
– Replicates the Ruismaker Annabella hardware drum machine
– Light on the CPU, so you can run lots of Ruismakers simultaneously
– Has an extra compact 4″ UI mode; especially for iPhone SE and iPhone 5S
– Fully automatable parameters (requires host support)
– Fully MIDI controllable using MIDI CC
– Download the advanced guide on for more details about parameter automation, available instruments and MIDI implementation

Do you have requests for new drum synth sounds that can be added to the available models? Let us know!

iOS Audio Units are supported on iPads (iPad Air, iPad Mini 2 and up) and iPhones (iPhone 5S and up) with iOS 9 and higher.

What’s New in Version 1.0.2

– Fixed jumpy knobs (smoother/finer adjustments)
– New sound models
– New Factory kits
– Improved dynamics engine
– Categorization in sound list
– Improved automation handling
– Reduced CPU usage and minor fixes

Note to iPad 4 users: due to a bug in Garageband you may be experiencing crashes (only on iPad 4). We’re working with Apple to solve the issue. In the meantime we recommend using another Audio Unit host with Ruismaker.

Given the fact that I was unable to download the app at this time(work calls), I cannot give my impressions of the app until a later time. I must say that this app has my attention, as it is an Audio Unit app, which requires a host app to work. This means you can run it in AUM or any DAW that features AU hosting. It streamlines a process for creating music. I will be curious to see how well this app plays with other apps and see if I can create a live set with it.

Until then, you can check out this app yourself by purchasing it here:
