FEATURES

FEATURES

VS-MIDI is a MIDI retrofit for Vermona Synthesizer. The VS-MIDI interface controls VCO, EG, VCF and VCA

circuits of the Vermona Synthesizer via MIDI commands.

The interface only receives MIDI data and converts them to signals for the Vermona Synthesizer control. The

instrument’s own control elements (keyboard, switches, knobs, etc.) are not transmitted as a MIDI data and

their status cannot be saved in the interface’s memory as a patch.

All functions of the interface are simply controlled by standard MIDI commands (CCs, Program Change, etc.).

Some special functions controlled by MIDI SysEx messages are available for advanced users.

The interface has internal memory for saving of interface’s own settings. Content of the memory can be backed

up in any MIDI DAW, sequencer, etc.

Box. MIDI input of the other (next in chain) MIDI device can be simply fed from MIDI-THRU/OUT output of the

interface (see fig. 1).

If there are no other MIDI devices to be used, only MIDI-IN cable is necessary (from MIDI output of host system

INTERFACE OPERATION

INTERFACE OPERATIONINTERFACE OPERATION

INTERFACE OPERATION

The interface doesn’t have any manual control element. All functions of the interface are controlled by

interfaces parameters (see chapter 4). The parameters can be set / adjusted by MIDI commands only. Most of

them are simply set by MIDI Control Changes - CCs (see chapter 5.1.2).

Working status of the interface is indicated by bi-color LED. The indication LED is placed under the “MAINS“

switch on the instrument’s front panel. The LED lights red in quiescent condition – it indicates power-on status

of the Vermona Synthesizer instrument. An interface activity can be indicated by the yellow light of the

indication LED. Mode of the LED indication is user selectable (see chapter 4.2.13). If there is an error occurred,

the indication LED starts to blink periodically (see chapter 6.2).

RESET STATUS

RESET STATUSRESET STATUS

RESET STATUS

When the Vermona Synthesizer instrument is switched on, the interface is disabled (it does not affect the

instrument) and the instrument can be used usual way like no MIDI interface has been installed. The interface is

now monitoring the incoming MIDI data.

3.23.2

MIDI MODE

MIDI MODEMIDI MODE

MIDI MODE

When an acceptable MIDI command (see chapter 5) is received, the interface turns to MIDI mode automatically

and takes control over instrument’s circuits (see fig. 3) accordingly to the incoming MIDI data.

work the standard way. If you want to use the instrument’s own keyboard again, you have to switch the

instrument off and then on again after a moment

.

Simultaneous usage of MIDI Notes and instrument’s own keyboard causes that the instrument is playing considerably out of tune (see chapter 6.1)!

5

Interface reset can be also executed by the MIDI common system command “Reset” or by System Exclusive message “HW Reset” (see MIDI SysEx

Communication manual).

The parameter adjusts assignment of received MIDI Note numbers to the instrument keys. The parameter value

specifies exactly the number of MIDI Note which is assigned to the lowest key of the instrument’s keyboard. It

can be changed by MIDI CC Nr. 16 - see chapter 5.1.2.2.

The parameter value can be from 0 to 84. If value 0 is set, the lowest key on the keyboard corresponds to MIDI

Note Nr. 0 and the highest key corresponds to MIDI Note Nr. 43. If value 1 of the parameter is set, the lowest

key on the keyboard corresponds to MIDI Note Nr. 1 and the highest key corresponds to MIDI Note Nr. 44, etc.

up to value 84 of the parameter when the lowest key of the keyboard corresponds to MIDI Note Nr. 84 and the

highest key corresponds to MIDI Note Nr. 127. See fig. 6 on next page for more details.

The parameter adjusts maximal allowed VCO’s pitch bending for full range of MIDI Pitch Bend. It can be

changed by MIDI CC Nr. 17 - see chapter 5.1.2.2.

The parameter value is from 0 to 12. The 0 value switches the pitch bend off – the Pitch Bend MIDI command is

ignored. The values of 1 to 12 are equal to bending the pitch in semitones. Bending up to ±1 octave is available

thus.

Remark:

Remark:

The detune range of the VCO upwards can be limited for the highest octave and detune range higher than

approximately 4 semitones. This limitation is caused by the construction of the Vermona Synthesizer and it cannot be removed.
