Single Manual Continuo Keyboard

1M Continuo Keyboard

1M Continuo Keyboard

We have just complete a single manual keyboard for a customer who wanted a portable Hauptwerk-ready keyboard that can be used whilst seated or standing up.  A neat music desk has been designed that can be set at 3 angles and folds flat for ease of transportation.


A Fatar TP/60LF keyboard and 11 thumb pistons were specified. Our velocity sensitive USB bus-powerd MIDI encoder was fitted which supports MIDI in and out (with merge) and the connection of up to 2 expression pedals.

Other keyboards could be specified such as Fatar TP64/LF with wood cores, Ebony naturals and Cherry sharps or keyboards from UHT for those who want the ultimate feel or maybe a shorter compass.

We are also planning to build mobile console to enclose a computer and 2 x 8″ studio monitors. Watch this space!

So if you conduct a choir, this could be a very useful continuo organ solution when used with a sample set such as the Prib Chamber Organ from Sonus Paradisi.

4 Manual Clayesmore Console

Our orders seem to be split about 50 / 50 between the minimalist Charterhouse and the more traditional Clayesmore consoles.

Below is a rather nice 4 manual Clayesmore Console that we have just installed. Of note is the adjustable music desk, the customer wanted the ability to adjust the desk fore and aft and up and down. 61 engraved thumb pistons, 20 Taylor brass toe pistons and 3 expressions were also specified.

A secondhand 2009 Mac Pro with 32Gb of RAM was used with an Echo Audiofire 12 and 2 Iiyama 2253MTS touchscreens and Touch Base drivers.

Salisbury Cathedral Replica

4M Modular

4M Modular

Our latest installation is a 4 manual modular console – now known as “The Charterhouse”. The customer, a former employee of Salisbury Cathedral, wanted a replica console to use with the Milan Salisbury sample set. We retained an existing Osmond 30 note pedalboard and bench. 2 x 22″ Iiyama touchscreen monitors were used to accurately replicate the organs stop jambs. A Mac Mini was internally mounted reducing the external wiring to just a power and firewire cable. The audio interface is an Echo Audiofire 12 which is connected to 6 x Mackie HR824 powered studio monitors and a KRK sub.

There were some teething troubles with the Mac (2Ghz quad core i7 Mac Mini Server with Intel HD3000 graphics not supporting 2 rotated monitors). After replacing the Mac with a later 2.6Ghz machine with HD4000 graphics, all is well. Again we used Touch-Base drivers for the touchscreens.

This minimalist console looks fantastic in the newly decorated music room. A very satisfactory installation.

2 Manual Key Stack


We have just delivered a 2 manual key stack that has turned out particularly nicely. Specification below. The customer already had a MIDI pedal board, expression pedal and Viscount and Content expanders, sadly no Hauptwerk (yet). Total ex works cost was approx. £1880 + VAT.

      • 2 Fatar TP/60 keyboards
      • 6 divisional pistons per manual
      • 10 generals
      • 3 reversibles and combination setter and general cancel
      • Removable oak music desk
      • MIDI in and out supporting MIDI merge
      • 2 continuous controllers for expression pedals
      • USB (can be bus powered if required)
      • Toe piston connectors (up to 28)
      • Renatus serial pedalboard connector



Piston Layout


When designing an organ, one of the variables needing consideration is piston layout. Annoyingly, there is no definitive specification.

Clive Sidney has come to the rescue by providing a suggested British piston layout . Click on the link below.


Bear in mind that  we use a piston spacing of 28.5mm instead of the suggested 32mm which yields a greater piston density, particularly useful when using touchscreens. This gives 29 piston positions across the keyslip, combination setter at position 0, the first divisional at position 12 and general cancel at 29.

Romsey OrganWorks can create any piston layout including user defined nomenclature.

Touchscreens on a Mac


Without question, a Mac is the superior choice when it comes to a computing platform on which to base a Hauptwerk organ. However unlike Windows 7 and 8, OS X has no touchscreen support, a Steve Jobs legacy, iOS devices have touchscreens, OS X devices don’t.

When 2 touchscreens are connected to a Mac, it “sees” 2 displays and 2 USB HID controllers it has no idea that these 4 devices are actually 2 physical touchscreens.

A custom driver is required to map the USB HID controllers to display areas and calibrate the touch coordinates with monitor.

Touch-Base are market leaders in this area. Their drivers are commercial, but the expense is well worth it.

The first thing to do is to work out what USB HID controllers are installed in your touch monitors. To do this, connect the touchscreen USB connections to your Mac. Then click on the Apple logo in the top left of the screen and select About This Mac, More Info…, System Report… Then click on USB in the Hardware section. Navigate the USB tree until you find the HID controller(s). Make a note of the Manufacturer and product ID (PID). usb-config

Then go to the Touch-base download page. Add your contact information and find the controller. You may find that there are multiple drivers for a given manufacturer. In that case, select one and you’ll see the PID for the selected driver. Compare it to the PID in the system report. Below is the driver that matches the system report above, 3023.touch-base

Then click Request Download. You’ll be emailed a link to the driver.

If you have difficulty locating your driver, Touch-Base will help identify the touch screen if you email the USB vendor and product id.

Please note, that the driver from the download site is a trial driver with functional restrictions (100 touches) and supplied to test out the hardware.

Install the driver. Then run UPDD Console.

The primary job of UPDD Console is to associate the HID controllers with their respective displays. The mapping between display and HID controller is static. See the Driver/Device settings – the UPDD Console in Note, changing configuration requires a re-boot.

To complicate matters, display configuration is dynamic, OS X will automatically configure the displays. This default configuration can be changed in System Preferences, Displays.


Whenever monitor configuration is changed, the mapping must be reestablished with associated HID controllers. So once a working configuration has been achieved, monitor and USB configuration should not be be changed.

Once configuration is complete and the Mac has been re-booted, run UPDD-Calibration. This is a simple affair,  just follow the on-screen instructions.

Below is suggested installation sequence.

  1. Check USB Configuration in USB tree (Manufacturer and PID)
  2. Download driver and install
  3. Configure Monitors in System Preferences, Displays
  4. Run UPDD Console and associate each HID controller with each display
  5. Re-boot
  6. Run UPDD Calibration
  7. If all functions as expected, purchase the driver
  8. Play!

December 2013

December was a busy month for Romsey OrganWorks with 4 organ rentals.

Royal Holloway College

Royal Holloway College

The first was at Royal Holloway College. We supplied an orgue de chœur to compliment the Harrison & Harrison in the chapel for the Vidor double organ mass. We used the excellent St. Eucaire de Metz Cavaillé-Coll sample set. It only has 22 stops, but really packs a punch.

Next was Newent Choral Society. They were doing a Britten-fest including Rejoice in the Lamb and the Jubilate. The Hereford Cathedral sample set was pressed into service. This was the first outing for our new subwoofer – a QSC KSub. It is very powerful!.

Then came the WI Carol Concert at Cheltenham Town Hall. The fabulous Rushworth and Dreaper organ is unplayable and will be removed to make room for new dressing rooms. Again Hereford was used with over 3KW of audio. It was an incredible experience. 2 sell-out concerts with over 900 in attendance at each.

Below is a short clip of the National Anthem. It’s poor quality as it was taken with an iPhone from the rear balcony, but the organ can be heard.

Finally came Tewkesbury Abbey. Another double organ French mass, this time the Vierne Messe Solennelle. Again the St. Eucaire de Metz sample set was used to accompany the mighty Milton Organ. The acoustics were so good in the Abbey that we configured the samples fully-dry. The result was fantastic!

4 Manual Hauptwerk Conversion

The organ below was originally built by Wyvern with Bradford internals. We were approached by the owner to make it Hauptwerk compatible. We investigated retro fitting MIDI to the existing electronics. However this strategy was rejected due to the limitations of the Bradford hardware.  The instrument was completely stripped down and rebuilt at the Renatus factory. The only components retained were, the casework, pedalboard, expression pedals, drawstops and their associated power supplies and pistons. 4 Fatar TP/60s were installed with new key slips, key blocks and Renatus MIDI encoders that also control the stops, expressions, pedalboard and LCD display. The instrument was completely

As the instrument was to be used with the Hereford Cathedral sample set from Lavender Audio, some of the stop heads needed to be re-engraved and the piston layout was also altered.

The console also drives 4 real ranks of pipes. The owner wanted these ranks to supplement the digital Hereford ranks rather than replace them. This required a custom organ definition that included the new stops so their state could be maintained by the Hauptwerk combination action, and MIDI output to be directed to decoders controlling the pallet solenoids.

Hauptwerk and the Hereford sample set was loaded onto an Apple Mac Mini with a quad core i7 processor, 256Gb SSD and 16Gb ram. An Echo Audiofire 12 drove 4 Behringer amps which in turn powered 2 pairs of Def Tech tower speakers and sub and 2 pairs of Jamo speakers.

The organ will be inaugurated at a concert on Saturday 7th September 2013. Details below
