The valid prices can be found in the price list in the accessories section.

Other types of keyboards, keyboards with monophonic after touch or weighted keys are available only as special orders. Please look at the manufacturers website www.fatar.com which keyboards are available. The prices of the currently available keyboards are available here: Prices_Keybeds.pdf. We ask for your understanding that we are not able to offer consultation and service for keyboards we do not use in our products (e.g. feeling, measures, weight, schematics) as we only know the specifications that are available at the manufacturers website www.fatar.com. Unfortunately not all types of keyboards shown on their website are always available but only if they are currently in production or in stock. The minimum delivery time is about 8-12 weeks as we normally add these special orders to regular keyboard consignments to keep the additional shipment charges as low as possible. Please contact our sales office for details (sales@doepfer.de). We also expect a down payment of at least 50%. Pay attention that it is not possible to return specially ordered keyboards and that there will be no service from us in the future for these keyboards (e.g. no spare parts like keys, springs, contacts, weights) as we do not have these keyboards as regular products available ! We only offer to order the keyboards for you as Fatar does not sell to end users. The left picture shows a combination of three church organ keybeds TP/60 with 61 keys each, mounted together with suitable accessories (so-called "chassy"). Each keybed can be equipped with the MKE electronics to obtain a multi-manual church organ Midi keyboard. The chassy shown in the picture is suitable only for the classical TP/60 organ keybed series (TP/60L, TP/60LF, TP/60LW, TP/62LW, TP/63LW, TP/64LW and TP/60LWR). For all other versions of keybeds (e.g. TP/6, TP/7, TP/8, TP/9 or TP10) the chassy cannot be used. Two types of chassy are available: the lower chassy for all lower keybeds and the upper chassy for the uppermost keybed. For the assembly shown in the picture altogether four lower chassy and two upper chassy are necessary.

dimensions:
overall: ~ 67 x 33 x 63 mm (mounting angle, wheel and potentiometer)
only the mounting angle: ~ 53 x 20 x 40 mm (without wheel and potentiometer)
diameter of the wheel: ~ 67 mm
width of the wheel: ~ 10 mm
distance of the mounting holes of the mounting angle: ~ 32 mm

Technical remarks: Pay attention that not the full rotating angle of the potentiometer is covered but only about 40%. If the end terminals of the potentiometer are e.g. connected to GND and +5V only a voltange range 0...+1.6V is covered !  Especially for DIY/OEM applications one has to pay attention to the limited rotating angle. The electronics of our keyboards (LMK2+, LMK4+) and the DIY/OEM electronics MKE and Wheel Electronic take into consideration this special quality.

The modulation wheel can be combined with these electronics: Wheel Electronic, LMK2+, LMK4+, MKE

The valid price can be found in the price list in the accessories section.

dimensions:
overall: ~ 89 x 76 x 64 mm (including wheels)
only the black box: ~  89 x 76 x 45 mm (without wheels)
diameter of the wheels: ~ 67 mm
width of the wheel: ~ 15 mm
grid of the mounting holes:  ~  72 x 61 mm

Technical remarks: Pay attention that not the full rotating angle of the potentiometer is covered but only about 40%. If the end terminals of the potentiometer are e.g. connected to GND and +5V only a voltange range 0...+1.6V is covered ! In addition the two potentiometers work in the opposite direction as one is mounted from the left and the other from right side to the wheel ! Especially for DIY/OEM applications one has to pay attention to these special features. So far the modulation wheel set is not used in any of our products. In particular it cannot be used in combination with the electronics of LMK2+, LMK4+ and the DIY/OEM electronics MKE. But the modulation wheel set can be combined with Wheel Electronic.

The valid price can be found in the price list in the accessories section.

dimensions:
overall: ~ 41 x 41 x 36 mm (including lever and potentiometers)
only the black box: ~ 30 x 30 x 25 mm (without lever and potentiometers)
grid of the mounting holes:  ~  24 x 24 mm

manufacturer: ALPS

The joy stick potentiometers cover the complete rotation angle. If the end terminals of the potentiometers are e.g. connected to GND and +5V the full voltange range 0...+5V is covered !

The joy stick is spring-loaded, i.e. the lever returns back to the neutral position as soon as it is released. If the spring is removed for one or both directions (e.g. by means of a side cutter) the joy stick is no longer spring-loaded for this direction(s). But as the spring has to be destroyed during the removal this cannot be re-established !

The valid price can be found in the price list in the accessories section.

Joy stick I can be combined e.g. with Wheel Electronic or Pocket Electronic.

The picture shows the joy stick with the additionally available aluminium lever. The aluminium lever is not included but has to be ordered separately (additional price).

dimensions:
overall: ~ 72 x 60 x 66 mm (including lever and potentiometers)
diameter of the inner ball: ~ 50 mm
length of the lever (measured from the ball surface):  ~ 17 mm
cross section of the lever:  ~ 6 x 6 mm
grid of the mounting holes:  ~  42 x 48 mm

manufacturer: Fatar

Technical remarks: Pay attention that not the full rotating angle of the potentiometers is covered but only about 40%. If the end terminals of the potentiometer are e.g. connected to GND and +5V only a voltange range of about +1.5 ... 3.5 V is covered (a bit different for different specimens) ! So far we have no Midi electronics available that can be used in combination with joy stick II. The joy stick is spring-loaded, i.e. the lever returns back to the neutral position as soon as it is released. One of the spring can be removed very easily by nipping the spring with a side cutting pliers. The second spring is hidden inside the joy stick.

special fader potentiometer as used in d3c, especially for organ applications, resistance: 47kOhm linear, 16 grids (17 positions), black lever, labelled "1" ... "8" in white color, dimensions: about 146 mm (lenght) x 12.5 mm (width) x 10 mm (height without solder pins) / 18 mm (height incl. solder pins).
no longer available

We offer suitable knobs too. They are available only as a complete set with 20 knobs (same as the historical model):

Single drawbar knobs are not available but only as the knob set specified above. The knob set is available only in this combination of knobs !

The valid prices can be found in the price list in the accessories section.

Discontinued ! Sale while stock lasts !

Position Sensor: Same as used in R2M resp. A-198. A linear position sensor from the industrial sector. Measures: about 575 x 22 x 0.5 mm. Usable length about 50 cm. Works like a normal fader potentiometer but the wiper is lifted off as long as the sensor is not touched. As soon as the sensor is touched the wiper is connected to the resistance track and can now be treated like a normal linear potentiometer. The sensor has a self-adhesive base and a 3 pin connector (same functions as a potentiometer). The resistance of the sensor is about 12,5 kOhm (+/- 20%). The position sensor cannot be shortened and is available only in this length. Changing the production for another length would cause high costs as new tools would be necessary. For measures beyond 50 cm even new machines would we required that are able to process larger workpieces.

The valid price can be found in the price list in the accessories section.

Pressure Sensor (new version): Same as used in the new versions of R2M resp. A-198. A pressure position sensor from the industrial sector. Measures: about 610 x 15 x 0,35 mm. Usable length about 60 cm.  It has a self-adhesive base and a 2 pin connector. The sensor reduces it's resistance while the pressure increases: from more than 1MOhm without pressure to about 1-2 kOhm at moderate pressure and down to a few hundret Ohm at high pressure, but the high pressure range is not meaningful for musical applications. The pressure sensor can be cutted off to any length.

The valid price can be found in the price list in the accessories section.

Pressure Sensor (old version): Same as used in the old versions of R2M resp. A-198. A conductive rubber (about 245 x 13 x 1 mm) that reduces it's resistance while the pressure increases. The rubber can be assembled between two conducting surfaces (e.g. pc boards) to measure the variable resistance. For the complete length of the R2M resp. A-198 manual 2-3 of these sensors are required.

The valid price can be found in the price list in the accessories section.
