System Parameters    Preset Parameters    System Functions    SysEx Message
 

System Parameters ^^^^^
These parameters affect basic functions of the interface. They are valid for every preset.

MIDI Channel
Number of the MIDI channel used for the communication with a host MIDI system can be selected with this parameter.

ENV Break Pulse Duration
Parameter sets the duration of a break pulse for instrument's ENV generator if the instrument is working in "Non-Legato" mode. Length of the break impulses are defined by the following formula:
   LENGTH = (PARAMETER_VALUE + 4) / 4 [milliseconds]

Bulk Dump Data Load - Generate button
Generated Bulk Dump message changes the values of all parameters in a system memory bank. Requested values of all system parameters must be set before the Bulk Dump Message is generated.

Bulk Dump Data Request - Generate button
Generated Bulk Dump message is inquiry for the content of a system memory bank. Immediately after the message receiving the interface sends the Bulk Dump Data Save / Load message as reply.
 

Preset Parameters ^^^^^
These parameters define the sound properties of SH-2 / SH-09 instrument.

Preset Number
Selection of the number of preset memory bank to which the data will be stored (Bulk Dump Data Load) or from which the data will be read (Bulk Dump Data Request).

VCO PITCH - Key Shift
The instrument's VCO tone range can be transposed with a help of this parameter:

VCO PITCH - Aftertouch Bend
Parameter sets the range of bend (detune) allowed for the Channel Aftertouch command. Maximal detune is +-4 semitones.

VCO MOD - Wave
Parameter sets the waveform of the internal software LFO for the VCO modulation (frequency sweep):

VCO MOD - Polarity
Parameter sets the polarity (direction) of the VCO frequency modulation by the internal LFO:

VCO MOD - Rate
Parameter sets the rate of speed of the internal LFO:

VCO MOD - Wheel Amount
Parameter sets the VCO modulation amount for the Modulation Wheel (CC1) command.

VCO MOD - Aftertouch Amount
Parameter sets the VCO modulation amount for the Channel Aftertouch command.

VCO MOD - Retrig
Parameter allows the syncing of the internal LFO to each of received Note-On commands.

VCF CUTOFF - Frequency
Parameter limits the basic cutoff frequency of the VCF.

VCF CUTOFF - Key Follow
Parameter sets the level and direction of the VCF affecting by received MIDI note number.

VCF CUTOFF - Velocity Amount
Parameter sets the level of the VCF affecting by velocity of the MIDI Note-On commands.

VCF CUTOFF - Aftertouch Amount
Parameter sets the level of the VCF affecting by the Channel Aftertouch commands.

VCA LEVEL - Key Follow
Parameter sets the level and direction of the VCA affecting by received MIDI note number.

VCA LEVEL - Velocity Amount
Parameter sets the level of the VCA affecting by velocity of the MIDI Note-On commands.

VCA LEVEL - Aftertouch Amount
Parameter sets the level of the VCA affecting by Channel Aftertouch commands.

VCA LEVEL - Volume Mode
Parameter selects the method of a volume control for the instrument's VCA via Control Changes Volume (CC7) and Expression (CC11) commands.

CONTROL - Bender Mode
Parameter selects the method of control for the instrument's bender.

CONTROL - Indicator Mode
Parameter selects the function of the interface's LED indicator.

Bulk Dump Data Load - Generate button
Generated Bulk Dump message changes the values of all parameters in a permanent preset memory bank. Number of the requested preset memory bank can be set in the "Preset Number" box. Requested values of all preset parameters must be set before the Bulk Dump Message is generated.

Bulk Dump Data Request - Generate button
Generated Bulk Dump message is inquiry for the content of a preset memory bank. The Number of requested preset memory bank must be set in the "Preset Number" box before the Bulk Dump Message is generated. Immediately after the message receiving the interface sends the Bulk Dump Data Save / Load message as reply.
 

System Functions ^^^^^
These functions launch a special procedures:

Change Preset
The actual preset number (1 to 24) can be changed or requested for the actual preset number that can be generated. In that case the interface will transmit the message:
   F0 00 20 21 ii 5B 30 00 nn xx F7 [hex]
where "nn" is the number of actual preset (00 to 17 [hex]).

Store Preset
The actual values of preset parameters will be stored from the edit buffer to selected preset memory bank.

Reset
The message for the hardware reset launching or for the total factory reset procedure will be generated.

SW Version Request
The request for the installed SW version will be generated. The interface will transmit the message:
   F0 00 20 21 ii 5B 30 03 vv vv xx F7 [hex]
where databytes "vv vv" are the numbers of SW version.
 

SysEx Message ^^^^^
The text form of generated SysEx Message can be set with a help of two select-boxes:

Select Hex Byte Form
The text form of generated hexadecimal bytes can be chosen by this select-box. Requested form must be selected before any "Generate" button is pressed.

Select Delimiter
The delimiter between the generated hexadecimal bytes can be chosen by this select-box. Requested delimiter must be selected before any "Generate" button is pressed.

Text Area
The System Exclusive Messages are generated in a hexadecimal form as the text in this area.

Reset Button
This button sets all parameters to their default values and it clears the text-area too.
