About Us

We are manufacturer of interfaces supporting MIDI protocol, allowing you to control practically anything. We can supply all electronic interfaces you may need to automate your organ, accordion etc., or build your own concept musical instrument. Since we are mainly concentrated on organs, let's see few possible ways to use MIDI technology in organs.

Existing electric/relay control system of a pipe organ built 20 or more years ago, now obsolete, can be replaced with MIDI control system. After that the pipe organ will remain same pipe organ, but the electrical installation will become times simpler and reliable. It will become MIDI-controlled pipe organ. You won’t need anymore bunch of electrical cables running between organ console and pipe chamber. Only thin MIDI or data cable will be sufficient for this communication. The huge preset electro-mechanical system consisting of thousands of relays and switches can be now replaced with digital memory system, as small as cigarette box, but capable to memorize and recall thousands of stop presets.

The MIDI technology will not only simplify the organ installation, but will make the organ MIDI compatible, so that it can work separately or together with other MIDI devices or computer software when/if this becomes necessary. Organ pipes can now be played by external MIDI keyboard. From the other side, the organ console can now play sounds on MIDI expanders, virtual pipe organs etc. Finally, organist performance on an MIDI-controlled organ can be recorded on MIDI recorder (a.k.a. MIDI-filer), then played back on the real organ pipes without player sitting on the bench! This is not audio recording, this is real action recording. While playing back, the sound will come from pipes. Once the organ has been turned into MIDI controlled organ, it can be easily expanded with hundreds of electronic sampled expanders and/or virtual pipe organ stops by adding computer running Virtual Pipe Organ software and good acoustic system. Having been expanded this way, the organ becomes hybrid (a.k.a. mixed) organ. The most popular Virtual Pipe Organs suitable for setting up an mixed organ are Hauptwerk, jOrgan, GrandOrgue, MidiTzer.

In many cases customers have organ consoles salved from old church organs and need to convert them to MIDI consoles in order to use them home. Most of people cannot afford building real pipe organ home, but definitely can afford MIDI conversion of an existing old organ console or console built by themselves, to be used to control virtual pipe organ software. For such conversion they need MIDI interface boards and optional key contact systems, organ parameter displays etc. We can supply all these products at one stop.

Sometimes customers try to set up their organ console from scratch step-by-step, taking keyboards from old non-functional synthesizers, pedal boards from organs and building their own stop jambs. We are happy to help with advices and suggestions in such projects.

Most of our interfaces are plug-and-play or require simple configuration steps. They can be also factory configured for you so that you only install and power them up. We provide full online assistance during the process of setup.

To the special attention of both professionals and amateur organ builders: we offer bundled products, ready configured per your requirements, suitable for fast MIDI conversion of organs. Full installation and configuration information for our products is available online. Our products are covered by online technical support and 1 year warranty.

No matter whether you need MIDI-interface able to scan 2 keyboards of 5octaves and a 32 notes pedal board, or you are looking for a full 128 note MIDI decoder for pipes, or LCD modules for displaying Hauptwerk parameters and messages, on our web page you will find all MIDI components needed by an organ builder.

Finally, here comes the cherry on the cake for MIDI organ builders: one of our recent products we are proud of is eStop - intelligent stop controller which uses an e-ink panel to allow dynamically displaying stop names per loaded VPO/sampleset.

But our products are not dedicated only to organ as much as MIDI standard is not dedicated to organs only. Both they are dedicated to the MUSIC. Many customers use them to convert to MIDI piano keyboards (with velocity), separate detachable pedalboards, accordions,concertinas, bandoneons and other bellow-operated instruments, exotic one-of-a-kind instruments, stage control systems for sound, light, etc.

Over the years we have proven that we are one if the best in providing custom MIDI design solutions! Our happy clients from all around the World can confirm that.
