Gate Input (min. +5V)
CVN Input (defines the Midi note number), 1V/octave standard, range 0...+10V (i.e. 10 octaves)
CVV Input (defines the velocity value assigned to the Midi note message), can be used alternatively for Midi volume (CC#7), range 0...+5V
CVC Input (free assignable to any Midi control change number), range 0...+5V
For both sub-units a common CV Transpose input is available (1V/octave, range 0...+10V). The voltage applied to this input is added internally to CVN before the Midi note number is generated. It can be used e.g. to transpose two sequences simultaneously by one voltage.
How it works:
Whenever the rising edge of the Gate input is recogized a Midi note on message is generated. The note number corresponds to the sum of the voltages applied to the CVN input and the common CV Transpose Input. In Velocity mode the voltage applied to the CVV input is used to define the velocity data of the Midi note on message (in Volume mode a fixed velocity value 100 is used). As soon as the falling edge of the Gate input is recognized the corresponding Midi note off message is generated (i.e. with the same note number as the preceding Midi note on message). The voltages at the CVN and CV Transpose inputs during the falling edge of the Gate do not have an effect on the note number of the note off message ! In any case the note number of the preceding note on message is taken. Otherwise hanging Midi notes would occur !
The CVC voltage is permanently converted into the corresponding Midi control change message, as well as the CVV voltage provided that the Volume mode is chosen. The difference between Velocity mode and Volume mode is the function of the voltage applied to CVV. In Velocity mode the voltage CVV is used to define the velocity value of the corresponding Midi note on message and is measured only during the rising edge of the Gate input. In Volume mode the CVV voltage is permanently converted into Midi Volume messages (Midi control change #7).
Adjustment of the Conversion Parameters
The conversion parameters for each unit are adjusted by means of the Learn button in combination with incoming Midi data (e.g. generated by a Midi keyboard connected to Midi In of the A-192-2). The learn mode is initiated by operating the Learn button for about one second. While the unit is in learn mode the corresponding LED is flashing. The next incoming Midi note on message is used to set the Midi channel and note reference for the sub-unit in question. The voltage currently applied to the CVN socket is assigned to the Midi note number of the note message.
Example 1: 0V are applied to CVN (or the CVN socket is left open) and a Midi note message with note number 36 on Midi channel 1 is sent while the upper sub-unit of the module is in learn mode: then a CVN voltage of 0V corresponds to Midi note number 36 for the upper sub-unit and the data are sent on Midi channel 1.
Example 2: +2.5V are applied to CVN and a Midi note message with note number 47 on Midi channel 11 is sent while the lower sub-unit of the module is in learn mode: then a CVN voltage of +2.5V corresponds to Midi note number 47 for the lower sub-unit and the data are sent on Midi channel 11.
If a Midi control change message is sent while the unit is in learn mode the control change number of the Midi message is taken for CVC. In addition program change messages will be used to set other parameters of the unit (e.g. to select the Velocity mode or Volume mode).
The data generated by the module are sent simultaneously on Midi Out and USB. Two or more A-192-2 modules can be daisy-chained via Midi Out - Midi In.
The two LEDs display the activity of the sub-units (i.e. if Midi data are generated by the unit in question).
Typical applications:
Conversion of analog sequences into Midi/USB data (e.g. A-155)
Generating random Midi notes (e.g. with CVN coming from A-118 or A-149-1, Gate e.g. from an LFO)
Generating Midi control change data from analog voltages"
These modes are planned (without obligation):
four voice monophonic (i.e. to control four monophonic voices by four succeeding Midi channels)
four voice polyphonic (i.e. to control four monophonic voices by one Midi channel) with several sub-modes (e.g. rotating / non-rotating)
two voice polyphonic (i.e. to control two monophonic voices by one Midi channel)
unisono
The basic mode is selected by means of a momentary switch (probably Mode or Algor.) and is shown in the LC display. Certain parameters of each mode can be edited (e.g. the midi channel(s), the midi reference note for 0V CV, assigned controllers for CV2 and CV3). For this the momentary switch Edit/Play is used. The parameter values (e.g. midi channels) are shown in the display and can be modified by means of the momentary switches 1...4. In Play mode the LEDs of these four switches display the gate states.
The range of the CV outputs (CV1...CV3) is 0...+10V (i.e. 10 octaves for CV1). The resolution is 12 bit. The gate voltages are 0/+5V (maybe even adjustable to 0...+10V for non A-100 applications).
We cannot yet specify a definite release date but hope that it will be available about fall/end of 2012.
But this release date is still without obligation !"
