    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. 2 Power Supply (9V DC 250 mA) 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.

    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.

Remark 2: If a device with switched trigger (S-Trig) is controlled by the R2M the inverted gate mode has to be selected and the hardware modification for switched trigger described in the attachment has to be carried out (removing a jumper inside the R2M).

    The transposition is controlled by the position sensor of the R2M. The gate length determines the relation between Midi clock resp. internal clock and the arpeggio tempo.

    In this mode the incoming Midi realtime messages start, stop, continue and clock are used to control the arpeggiator. The Midi transmitter connected to the Midi input of the R2M has to send these messages (at least start and clock). Otherwise the arpeggiator will not work.

    In any case it is the best solution is to adjust both the pitch scale of the R2M and the Midi receiver until a satisfactory cooperation between both devices is reached. As soon as the optimal setting is found it is recommended to stored the settings as a new preset (see page 20).

The voltage that appears at CV1 corresponds to the Midi note messages generated by R2M. CV1 follows the 1V/octave standard, i.e. the voltage difference is 1/12 V (0.0833V) for each semitone.
