In the note modeclosing of a contact generates the corresponding MIDI noteon message, opening generates note off - both withoutvelocity (velocity is fixed to 100). In the program changemode closing of a contact leads to the corresponding MIDIprogram change message.The (i.e. the MIDI note number assigned to thefirst contact) can be set to 0 or 36 with the second jumper.With two more jumpers one can transpose up/down oneoctave, i.e. +12/-12 semitones. Instead of these jumpers a3-position switch (1-0-1) working as an canbe soldered to the corresponding pins of the jumper pinheader. In this way the note offsets 0, 12, 24, 36 and 48 areavailable. If another note offset (e.g. 41) is required thecontacts are displaced correspondingly and the unusedcontact terminals are left free.In the program change mode the offset can be set to 1 or64, i.e. setting the program number range to 1-64 or 65-128(0-63 or 64-127 in MIDI code). With two daisy-chainedCTM64 the whole range 1...128 is covered.The plugs are used to connect up to 4potentiometers (e.g. rotary, slider, wheels) generating theMIDI messages

The 1/4“ jack socket can be used to insert a sustain pedal(contact type ”closed at rest” is required) generating theMIDI message (controller #64).The for all messages transmitted by theCTM64 is set with the last 4 jumpers.The 64 contacts are connected to four double row pinheaders with 16 pins each. 16 pin socket-connectors withflat cable can be connected to these pin headers (not

CTM RELAY BOARD

The is an expansion board for theuniversal . Thereason for this this additional board is the limited cablelength between CTM64 main board and the contacts(max. about 50 cm / 2 ft). By means of the relay boardthe cable length can be extended to 100 m (~ 300 ft) andeven more. The working principle is very simple: Therelay board is equipped with 16 reed relays that can beswitched via very long cables. The relay board is placednear the CTM64 main board and the contacts inside therelays are the new contacts for the CTM64 main board.Thus the cable length between the contacts and theCTM64 main board is less than 50cm but the cablesused to switch the relay can be very much longer. Foreach relay a screw terminal is available to connect asimple 2 pin cable with the controlling contact on theother side (e.g. a momentary or toggle switch). The relayboard is operated with a separate power supply to obtaina complete galvanic separation between the relays andthe CTM64 main board.These are the most important features:

An external power supply with 7-12V DCoutput is required. The required current depends uponthe number of relays that have to be switched actually.Each relay consumes about 10mA. The full installation(i.e. 4 relay boards, all relays in operation) requires apower supply with about 640 mAadditional screw terminal to operate several relayboards with one power supply onlyconnection between each CTM relay board and theCTM64 main board via 16 pin ribbon cable, and onesingle cable (common line) that leads from the CTM64main board to all relay boardsthe 16 pin ribbon cable is included with the relayboardthe power supply has to be ordered in addition (onlyone required, even if more than one relay board isused), see accessories and price list

A note on message will setthe corresponding TTL output to a high level (+5V),the note off message will reset the output to a lowlevel (0V). With an additional jumper this bevaviourcan be set to the other way round (note on = low, noteoff = high) if reversed outputs are required.In the program change only one of the 64 outputs isactivated. The number of the activated output isidentical to the program change number received atthe MIDI input.The (i.e. the MIDI note number assignedto the first output) can be set to 0 or 36 with anotherjumper. With two more jumpers one can transposeup/down one octave, i.e. +12/-12 semitones. Thus thenote offsets 0, 12, 24, 36 and 48 are obtainable. Ifanother note offset is required the unused outputsremain unconnected.In the mode the can be set to1 or 64, i.e. setting the program number range to 1-64or 65-128 (0-63 or 64-127 in MIDI code).

Pocket Electronics (abbreviation:"PE" in the following) is an universalelectronics DIY kit to built your ownMIDI control box. Up to 16 controllingelements can be connected to PEtransmitting 16 different MIDI messages ondifferent (or even the same) MIDI channels.Essentially it contains the electronics core ofPocket Control but without the 16 controls (i.e.without potentiometers). Instead of this PE is usedto connect up to 16 controlling elements (e.g.rotary potentiometers, fader/slider potentiometer,touch switches, toggle switches, foot switches,foot controllers). The controlling elements are notincluded but have to be added by the customer.Even voltages sources can be used instead of thecontrolling elements provided that the voltagesapplied are strictly within the range 0...+5V(referenced to PE GND)! Voltages beyond thisrange will destroy the electronics !The 16 controlling elements resp. control voltagesare connected to two double row pinheaders (10pins each). To these headers two 10 pin ribboncables are connected. The controlling elementsare connected to the free ends of the ribboncables. In this way the controlling elements can bepulled off from the electronics very easily.Additionally a 4 pin connector is available toconnect a button and LED (snapshot function ofPocket Control).Functionally PE is identical to Pocket Control, i.e.the most common Midi messages can begenerated (any controller, after touch, pitch bend,common RPN resp. NRPN controller, but noSysEx messages). PE has 128 presets availablefor the assignement of MIDI events to the 16controlling elements. The editor program (PCversion) can be downloaded for free from our website www.doepfer.de and enables the user toprogram his own 128 presets. The presets areselected with DIP switch or incoming MIDIprogram change messages. For more detailsplease refer to the Pocket Control information ).

PE is equipped with MIDI In and MIDI Out. Theincoming MIDI messages are merged to the datagenerated by PE. In this way several PE can belinked together to obtain larger controller arrayswith more than 16 elements.Even the combination of PE and CTM64 ispossible to add controller events to the note orprogram change events generated by CTM64.PE is available only as an assembled and testedpc board. The pc board measures are about 80mm (length) x 56 mm (width) x 25 mm (height).Five mounting holes with 3 mm diameter areavailable for mounting the pc board to a suitablebase e.g. with distance sleeves or spacers andscrews. PE includes two 10 pin ribbon cables(about 30 cm each), button and LED (snapshotfunction) and the power supply.ÊWe do not offer a suitable housing as this wouldhave to be completely different for variouscombinations of controlling elements.An external power supply (7-12VDC@min.100mA) is required for the PE. It is included withthe PE (230V version with European mains plug).Electronic basic knowledge is required to installthe PE electronics and to connect the controllingelements resp. control voltages. If you are notsure if your knowledge is sufficient please consultan expert. We cannot take back modules thatbecame defective because of wrong installationor wrong connection of the controlling elements orvoltages. We also cannot take back modules orcables which have been soldered by the user.

Dial Electronic (abbreviation: "DE" in the following) is anuniversal electronics DIY kit to built your own MIDIcontrol box with 16 rotary encoders (even called alphadials, endless potentiometers or similar). DE generates16 different MIDI messages on different (or even thesame) MIDI channels. DE can be combined with theuniversal keyboard electronics MKE, Pocket Electronic,CTM64 or MTC64 to obtain a unique controller that fitsexactly to the user's requirements.Essentially it contains the electronics core of Pocket Dialbut without the 16 controls (i.e. without rotary encoders).Concerning the MIDI functions DE is identical to PocketDial. Please refer to the Pocket Dial information fordetails.Up to 16 rotary encoders can be connected to DE andarranged in any positions of the case resp. front panelthat has to be built by the customer himself.

The controls are not included but have to be added bythe customer himself. A suitable control set is available.The additional controls of Pocket Dial (6 buttons and 4LEDs) can be connected via pin headers to DE. Buttonsand LEDs are not included with DE. Please look at theadditional available control set below.

DE is available only as an assembled and tested pcboard. The pc board measures are about 125 mm(length) x 70 mm (width) x 25 mm (height). Six mountingholes with 3 mm diameter are available for mounting thepc board to a suitable base e.g. with distance sleeves orspacers and screws.We do not offer a suitable housing as this would have tobe completely different for various combinations ofcontrolling elements. If you look for a ready built unitplease look at Pocket Dial.An external power supply (7-12VDC@min. 100mA) isrequired for the PE. It is included with the PE (230Vversion with European mains plug).

Previous Notice

available about early summer 2007

Wheel Electronic (abbreviation: "WE" in the following) is auniversal electronics DIY Midi kit designed to connectmodulation or pitch wheels. But it can be used also for joysticks, single or multiple foot controllers (analog or on/off),breath controllers or even normal potentiometers. In additiona connector for a sustain foot switch is available. Up to 4continuously variable "analog" elements and a "digital"switching element (e.g. a sustain foot switch) can beconnected.Application examples:

wheelspitch benderjoy sticksbreath controllersfoot controllers (continuos)foot switches (on/off), momentary or togglerotary potentiometersslider/fader potentiometers

Different elements can be combined simultaneously. Hereare some examples:

pitch bender, modulation wheel, volume control (rotary orslider potentiometer), breath controller and sustain footswitchpitch bender, three modulation wheels (e.g. modulation,volume, after touch) and sustain foot switchpitch bender, two modulation wheels (e.g. modulationand after touch), one rotary or slider potentiometer(volume) and sustain foot switchpitch bender, modulation wheel and joy sticktwo joy sticksfour foot controllers for volume control of four Midichannelsdual or tripe foot controller (on/off or analog) and rotary orslider potentiometertwo modulation wheels or switches to control the rotaryspeakers of the organ software B4 (von NativeInstruments), two rotary or slider potentiometers forvolume and expression

The four "analog" elements are connected to pinheaderswith 3 pins. For the "digital" switching element a pinheaderwith 2 pins is available. Four 3-pin cable sets and one 2-pincable set about 30cm each with suitable female connectorsare included.WE has some special features:The upper voltage that is assigned to the Midi data value127 can be adjusted exactly with a multi-gang trimmingpotentiometer in the range +3...+5V. This measure isnecessary e.g. for modulation or pitch wheels, footcontrollers or joy sticks that do not cover the complete angle

of rotation. Even breath controllers (e.g. Yamaha BC-1/2/3)output only about +3.5V maximal control voltage.For each of the four elements a jumper is used to select ifthe full voltage range (0...+5V) or the adjustable voltagerange is used for measurement. This is necessary ifdifferent elements are used simultaneously (e.g. modulationwheel and slider potentiometers).If an element is assigned to Midi pitch bend a "plateau" isused in the middle of the voltage/data range (data value64). This feature is meaningful in combination with spring-loaded wheels or joy sticks as due to mechanical tolerancesthe exact center position is not always reached.Four jumpers are used to select the Midi channel.Further four jumpers are used to select up to 16 differentcombinations of Midi control change numbers, pitch bend orafter touch - the so-called presets. A detailed list of allavailable combinations can be found in the user's manualThe elements connected to WE (e.g. wheels, joy sticks, footcontrollers, normal potentiometers, foot switch) are notincluded but have to be added or purchased in addition bythe customer. The Midi data range is 0...127 with 7 bitresolution.The sampling rate is about 50 samples/second.WE is equipped with MIDI In and MIDI Out. The incomingMIDI messages are merged to the data generated by WE-provided that the incoming Midi data range is not too big. Inthis way several WE can be linked together or combinedwith other electronics like CTM64, MKE, Pocket Electronicor Dial Electronic).An LED is used to indicate the Midi activity.WE is available only as an assembled and tested pc board.The pc board measures are about 60 mm (length) x 55 mm(width) x 25 mm (height). Several mounting holes with 3mm diameter are available for mounting the pc board to asuitable base e.g. with distance sleeves or spacers andscrews.We do not offer a suitable housing as this would have to becompletely different for various combinations of controllingelements.An external power supply (7-12VDC@min. 100mA) is used.Within Europe the wall outlet power supply adapter for 230Vmains voltage and European type mains plug is includedwith the WE. In other countries the power supply has to bepurchased by the user in his country. If there is a Doepferrepresentative in your country please ask the representativeif the power supply is included in your country.

MKE

external power supply

is an Universal Midi Keyboard Electronics to builtcustom-made Midi controllers that include a keyboard.Combining the MKE with our controller electronics PocketElectronic, Dial Electronic, Wheel Electronic, CTM64 orMTC64 allows the construction of an unique Midi controllerthat exactly meets the requirements of the user. Theseunits can be connected to MKE:

Any keyboard manufactured by FATAR/Italy with 2, 3, 4or 5 octaves (with velocity)By means of a special adapter board even the dynamicbasspedals PD/2A manufactured by FATAR/Italy can beconnected (avialable with 13, 17 or 20 keys)Pitch bend wheel (special spring-loaded rotarypotentiometer)Modulation wheel (special rotary potentiometer)Rotary or fader potentiometer for loudness/volumecontrol (Midi CC#7)After touch sensor or socket for sustain switch oranother potentiometer for any Midi controller

The MKE pc board has these controls available:6 rectangle momentary buttons with integrated LEDs3-digit LED display

The 6 buttons are used to control these parameters:Midi channel 1...16Transpose (lowest note = 0,12,24,36,48,60)Program change 0...127Controller number 0...127 resp. After touchUp/down (increment/decrement of the current value)

MKE is equipped with Midi In and Midi Out. The dataappearing at the Midi in are merged to the data generatedby the MKE. Several MKE can be daisy-chained orcombined with other OEM controllers (e.g. PocketElectronic, Dial Electronic, Wheel Electronic, CTM64) tobuilt a custom-made Midi controller.

MKE is available as an assembled and tested pc board.The pc board measures are about 68 mm (length) x 85(width) x 35 mm (height).Please specify in your order the type of keyboard (2/3 or4/5 octaves). This is necessary as the keyboards with 2and 3 octaves have different connectors compared to the 4and 5 octaves versions. Suitable cables to connect MKEand the keyboard are required. If you have no keyboardavailable we recommend to order the keyboard togetherwith the MKE as in this case the components are alreadyconnected and tested together. The MKE is available as apackage together with different types of keyboards (e.g.with the organ waterfall keyboard TP/8O).We do not offer a suitable housing as this would have to becompletely different for various combinations of keyboardsand controlling elements.An (7-12VDC@min. 250mA) isrequired for the PE. In Europe it is included with the MKE(230V version with European mains plug). For othercountries please contact the representative in your country.We have several accessories available: suitable keyboards(2, 3, 4 or 5 octaves), cables for the connection betweenMKE and the keyboards, wheels, cable sets for the wheelsand the volume potentiometer, wheels and sustain socket.For details please take a look at our price list (spare partssection) or ask our sales office (sales@doepfer.de).If you order the MKE without keyboard please specify thekeyboard that will be used (2, 3, 4 or 5 octaves). Theconnectors are different for the keyboards and theelectronics has to be equipped with the suitableconnectors. The cables leading to the keyboards are notincluded and have to be ordered in addition.

MBP25 is an electronics that was developed toconnect the non-dynamic basspedals PD/3manufactured by Fatar/Italy (for the dynamic basspedals PD/2A the MKE electronics can be used incombination with a suitable adapter board).Unfortunately Fatar does not offer bass pedals with 25or more keys but only versions with 13, 17 or 20 keys.As many customers have been asking for a basspedalwith 25 keys we decided to develop the MBP25 thatcan be used to connect one, two or three basspedalswith 13 keys each (Fatar PD/3) to obtain a 13, 25 or 37key basspedal. The above picture shows onepossibility how two PD/3 pedals can be combined toobtain a 25 key pedal with case.We offer a DIY/OEM package for a 25 key basspedal.It is made of two 13 keys pedals PD/3 and the MBP25electronics. One of the two pedals has to beshortended by one key as one of the "C" keys isredundant. Fortunately the PD/3 pedals use a plasticframe and can be shortened with passable effort. Bothpedals have to be mounted on a common base plateand a suitable case (e.g. made of varnished wood - asshown above) can be added. The base plate and thecase are and have to be added by thecustomer.

These are the most important features of the MBP25electronic kit:

6 black rectangle momentary buttons (about 12 x 22mm) with integrated LEDs (same as used into adjust these parameters

measures of the complete button area about 76 x22 mm3-digit LED display (about 19 x 38 mm) forparameter displaytwo connectors for basspedals (compatible to FatarPD/3)Midi In, Midi Out (connected via 30 cm long cablesto enable the mounting of the sockets at thedesired position)The data appearing at the Midi in are merged to thedata generated by the MBP25. Consequently theMBP25 can be connected to a Midi keyboard toadd the basspedal data to the keyboard data.power supply socket on board, in addition a 2-pinconnector is available to connect another powersupply socket near the Midi sockets (2-pin cable 30cm with suitable female connector is included)a 3-pin connector is available to connect a rotary orfader potentiometer that transmits Midi volume,even a foot controller (e.g. FP5) can be connected.the (fixed) velocity value can be set to any valuebetween 1 and 127.

not included

Remark: All basspedals manufactured by Fatar thatinclude velocity (PD/2A) are equipped with solid steelframes and cannot be shortened in such an easy wayand cannot be connected to MBP25.
