Important Notes
Power Unit
MAUSI has no integrated power supply. Therefore, you need an external power unit (not included). You may use Doepfer PS1
power unit or any other that meets the requirements listed below:
Voltage output: 7...12 V DC > 500 mA
Outer sleeve of the low-voltage plug = ground
Inner sleeve = +7...+12 V
MAUSI will not operate at wrong polarity. However, this will not damage the device, since a protection diode is incorporated.
A
Use the Doepfer PS1 power unit if you want to avoid any risk.
Cleaning and Servicing
There are no user-serviceable parts inside the device. Open the device only in case you want to adjust the gate voltage (s.
4.7).
Use a soft dry or slightly moistened cloth to clean the housing. If you want to remove obstinate dirt, moisten the cloth with a
small amount of mild detergent and wipe the dirt away. Be sure to rub the device entirely dry afterwards. Never use solvents
such as benzene, thinners, alcohol, and the like to clean the device.
1. Introduction
MAUSI is a MIDI to CV/SYNC interface. It allows MIDI control of analog synthesizers provided with control voltage (CV) and
gate/trigger inputs. Since you can select different CV characteristsics, MAUSI allows you to control synthesizers featuring
either V/octave (Moog, Roland, Sequential, A-100) or Hz/V characteristics (Korg, Yamaha). Moreover, you can select
gate/trigger (+5...+12V) or switched trigger control (S-Trigger).
MAUSI is equipped with two digital-to-analog converters (DAC), generating a CV of 0 V...+5 V. Thus, you can control not
only the pitch of your synthesizer but also another voltage-controlled component.
DAC 1 is firmly assigned to received MIDI note messages and converts these to corresponding control voltages available at
the CV 1 jack. The DAC operates with a resolution of 12 bits, providing a very accurate adjustment in steps of 1/4096th. DAC
2 can be assigned to velocity, after touch or any MIDI controller. The control voltages produced by this 7 bit converter
(operating in steps of 1/128th) can be accessed at the CV 2 jack.
Additionally, the software implemented in MAUSI offers functions such as portamento (glide), LFO and pitch bending. All
these functions can be switched on/off and controlled by MIDI controllers.
Furthermore, you can use MAUSI to synchronize older devices equipped with a SYNC interface to MIDI clock (e.g. Roland
TR-808, TB-303). Received MIDI real-time messages such as CLOCK, START, and STOP are converted to CLOCK and
START/STOP commands according to the sync standard. Normally, the SYNC CLOCK frequency is the same as the one of
the received MIDI clock messages. However, you can lower the SYNC CLOCK frequency by selecting a divisor. Furthermore,
the polarity of the SYNC CLOCK pulses can be set. In addition, it is possible to control devices such as arpeggiators by means
of a special cable (SYNC plug à ¼" plug).
All parameter changes can be stored to a special resident memory (EEPROM).
