Introduction
R2M is a so-called ribbon controller that generates control signals by moving the
finger on the ribbon manual. The output signals are generated as Midi and CV/Gate
control voltages simultaneously. Consequently R2M allows to control both Midi and
CV/Gate based equipment (e.g. analog synthesizers or analog modular systems).
R2M is the abbreviation of Ribbon to Midi.
R2M is made of two parts: the manual and the control box.
The manual is made of a 50 cm long linear position sensor and a pressure
sensor that is located below the position sensor. Touching the sensor with the finger
generates a voltage that is proportional to the position of the finger. In principle the
position sensor works like a 50 cm long fader (i.e. slide potentiometer). The slider is
represented by the finger. As soon as the finger touches the position sensor the
slider contact is closed and the finger position represents the slider position. If the
finger is removed the slider is removed too (i.e. the slider contact open).
Additionally a pressure voltage is generated that increases with the pressure applied
to the position sensor. Both voltages are fed to the R2M control box via a four-pin
cable (same as USB but does not transmit USB data). For the manual the same type
as the for the modular version A-198 is used.
Fig. 1
The control box contains two analog-to-digital converters and a microcontroller. It
converts the data coming from the manual (finger position and pressure) into the
corresponding Midi data resp. CV/Gate voltages. The Midi input is used to transpose
the notes generated by the R2M or to control the R2M arpeggiator functions. The
programming of the device is carried out with a LC display, 10 buttons and 6 LEDs.
The control box is available even without manual to make use of an already existing
A-198 manual and take advantage of the additional features of the R2M control unit
compared to the comparatively simple A-198.
Remark: To detect if the finger touches the position sensor the slider contact is pulled
high if the finger is removed. This corresponds to the rightmost point of the position
sensor. This has no influence on to the general operation of R2M but the last few
millimeters at the right rim of the manual cannot be used – i.e. moving the finger
within a few millimeters in the rightmost position has no effect.

Power Supply (9V DC 250 mA)
n
R2M does not have a built-in power supply. Instead it uses a plug-in type external
power supply (AC adapter). One reason for this feature is electrical safety. Keeping
danger voltages (mains) out of the R2M increases the electrical safety. Another
reason for the external power supply is the fact that line voltages and plug types vary
considerably from country to country. Using a plug-in external supply the R2M can be
used anywhere with a locally purchased power supply, thus keeping the retail price
down.

n
In Germany a VDE approved power supply is included with the R2M. In other
countries a power supply with suitable mains voltage and mains connector has to be
purchased separately by the user provided that the dealer resp. representative does
not enclose the power suppy. The power supply must be able to deliver 7-12 VDC
unstabilized voltage, as well as a minimum current of 250mA. The correct polarity of
the DC voltage connector is: outside ring = GND, inside lead = +7...12V. An external
power supply of high quality and safety should be used.
The R2M is switched ON by plugging the AC adapter into a wall outlet and
connecting it to the appropriate jack of the R2M. There is no separate ON/OFF
switch. If the polarity of the power supply is incorrect, the R2M will not function.
However, there is no danger of damage to the circuitry since it is protected by a
diode.
Manual connector (Ribbon Contr.)
o
The manual is connected to the control box with the 4-pin cable that is included.
Even though the same type of connector as for USB is used it is not
allowed to connect the control box or the manual to any USB device!
1
Both the USB device and the controller or manual will be damaged !
In this case the warranty will be void ! We will not compensate any
damage caused by ignoring this direction for use.

CV1 Out
r
This socket outputs an analog control voltage in the range 0...+5V that depends on
the position of the finger. It is normally used to control the pitch of analog equipment
(e.g. pitch on an analog synthesizer or VCO). The CV1 output follows the 1V/octave
standard (relevant only in the quantized modes).
CV2 Out
q
This socket outputs an analog control voltage in the range 0...+5V that depends on
the pressure applied to the manual. It can be used to control any other voltage
controlled parameter of an analog synthesizer (e.g. loudness, filter frequency,
modulation depth, LFO frequency, panning).
GATE OUT
p
This socket outputs a gate signal with +5V level. Normally the gate output is 0V in the
state and +5V in the on state. The gate is determined by the finger touch. As soon
off
as the finger touches the position sensor the gate turns on. If the finger is removed
the gate output turns
output turns to +5V or 0V if the finger touches the position sensor. Normally the gate
output is used to trigger the envelope generator (ADSR) of the analog synthesizer
controlled by the R2M.
. Positive or negative polarity can be chosen, i.e. if the gate
off
Even switched trigger or "S-trig" based equipment can be controlled (e.g. most of the
Moog and Arp devices) by removing a jumper inside the R2M control box. The pin
header for the jumper is labelled JP3 and is located just behind the gate socket. Keep
the jumper to be able to undo the S-trig modification.
Pay attention if you open and close the R2M case. Use a suitable screw driver only
and open/close the case very carefully. We cannot take back units with damaged
cases (e.g. scratches caused by the screw driver). Even the warranty will be lost if
any modification except the removal or installation of the jumper is carried out. If you
are not sure whether you are able to carry out the jumper removal/installation please
send the unit to your local dealer/representative.
MIDI Out
s
Connect the Midi Out socket of R2M with the Midi In socket of the device to be
controlled by the R2M (e.g. computer with Midi, Synthesizer, Expander, Sequencer)
via a suitable MIDI-cable. If only analog equipment is controlled via CV/gate the Midi
output is left unconnected.
MIDI IN
t
If you want to transpose the note messages generated by the R2M or make use of
the R2M arpeggiator functions the Midi In socket of the R2M is connected to the Midi
Out socket of the Midi device that generates the note on/off and clock messages
required for these features (see below).
If the arpeggiator of the R2M is
as the R2M are merged to the data generated by the R2M (so-called channel voice
messages, e.g. note on/off, control change, pitch bend, program change). Refer to
chapter 3-1 concerning the currently selected R2M Midi channel.
Page 6 R2M User's Guide V1.11
the incoming Midi data with the same Midi channel
off
This function can be used to modify Midi data with the R2M (e.g. adding pitch bend to
note messages on the same Midi channel).
If the arpeggiator is on the Midi merging function is not working. Incoming data on
other Midi channels than the currently selected R2M Midi channel are not merged !
The Midi input of R2M is not suitable for large amounts of Midi data (e.g. SysEx
strings or Midi messages coming from an computer sequencer) but only for small
data rates, e.g. the note on/off messages of a controlling keyboard. In case of large
amounts of incoming Midi messages data loss or delay may occur. Same applies for
Midi messages that do not match the R2M Midi channel.
If the transpose function, the arpeggiator or the merging of R2M Midi data to
incoming channel voice messages is not used the Midi Input of the R2M is left open.
Operation
R2M is switched on by plugging the AC adapter into a wall outlet and connecting it to
the appropriate power supply socket n. There is no separate ON/OFF switch.

Fundamental operation notes
R2M contains a lot of parameters that can be adjusted by the user and stored in
•
16 presets. Similar parameters are collected in the same menu.
A menu is activated by pressing the corresponding menu button. The active menu
•
is indicated by an illuminated LED.
Repeated pressing of the same menu button leads to the next parameter that can
•
be displayed and adjusted in this menu. The process is circular, i.e. after the last
parameter the first parameter of this menu appears again.
To exit a menu another menu button has to be pressed.
