FEATURES

FEATURESFEATURES

FEATURES

P6-M is a MIDI retrofit for Korg Polysix synthesizer. The most significant benefit of the interface is the control of

the instrument's VCF. Modulation of VCF by Velocity and Chnl Aftertouch MIDI commands will allow you to

achieve a much richer range of sound colours. Also additional LFO (with many user adjustable parameters) is

embedded for extended VCF modulation.

The P6-M interface controls:

• Instrument's keyboard (remote pressing of keys)

• Selection of Bank / Program (remote control of the PROGRAMMER section buttons)

• Selection of key assignment (remote control of the KEY ASSIGN MODE section buttons)

• Instrument's VCF modulation by MIDI Note Velocity and Channel Aftertouch

• Instrument's VCF modulation by additional LFO (synchronization by MIDI Clock is possible)

• Instrument's arpeggiator switching on / off (remote control of the ARPEGGIO button)

• Instrument's arpeggiator clock source and speed (synchronization by MIDI Clock is possible)

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.

The interface only receives MIDI data and converts them to signals for the Polysix 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 program.

Almost all functions of the interface are simply controlled by standard MIDI Control Changes (CCs) and Program

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

coming to the MIDI input are transferred unaffected to MIDI-THRU/OUT output of the interface

(THRU function). The THRU function enables another MIDI device(s) to be connected without additional MIDI

Thru-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 host system to MIDI-

IN input of the interface).

INTERFACE OPERATION

INTERFACE OPERATIONINTERFACE OPERATION

INTERFACE OPERATION

The interface has a single manual control element – Reset button – which turns the interface to reset status. All

other functions of the interface are set / controlled by MIDI commands only.

Working status of the interface is indicated by bi-color LED. The indication LED is off in reset status of the

interface when the interface doesn’t affect the instrument. The interface indication LED lights red in MIDI mode

when the interface takes control over an instrument circuit. If the LED indication function of the interface is

enabled (for details see chapter 4.2.16), selected function is indicated by green light or blinking of the indication

LED. If an error occurs, the indication LED starts to blink yellow (for details see chapter 6.1).

RESET STATUS

When the Polysix is switched on or when the interface’s Reset button is pressed, 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.

MIDI MODE

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

and takes control over some instrument’s circuits (see figs. 3 and 4) accordingly to the incoming MIDI data type.

Remote control of instrument’s keyboard, selected buttons on the instrument panel and VCF modulation is

allowed in the MIDI mode:

• Instrument’s keyboard (

①

on fig. 3 and 4) is controlled by MIDI Notes in parallel manner – both instrument’s

own keyboard and MIDI Notes can be uses simultaneously (see chapter 5.1.1).

• KEY ASSIGN MODE buttons (

②

on fig. 3 and 4) are controlled by MIDI CCs (Control Changes) in parallel

manner – both instrument’s buttons and MIDI CCs can be uses simultaneously (see chapter 5.1.2.2).

• PROGRAMMER buttons (

③

on fig. 3 and 4) are controlled by MIDI Program Change command in parallel

manner – both instrument’s buttons and MIDI Program Change can be uses simultaneously (see chapter

5.1.5).

• VCF fcM IN input (VCF cutoff frequency -

④

on fig. 3 and 4)

is

controlled by interface parameter. VCF fcM IN

input for external pedal is disabled when the interface controls the VCF modulation (see chapter 5.1.2.2).

• Instrument’s VCF can be also modulated by additional software LFO (

⑦

on fig. 4) controlled by the interface

parameters.

• ARPEGGIATOR speed (

⑤

on fig. 3 and 4) and source of the arpeggio synchronization are controlled by

interface parameters. SPEED knob on istrument panel is disabled when the interface controls the arpeggiator

(see chapter 5.1.2.3). External arpeggiator triggering is still allowed – the ARPEGGIO TRIG IN input (

⑥

on fig.

3 and 4) has the highest priority.

returns to basic reset status automatically. If the parameter is set to “Off”, standard error procedures will be

executed (see chapter 6.1).

Valid parameter values are 0 ~ 1: Value 0 is “Off” (autoreset disabled), value 1 is “On” (autoreset enabled).

. Values of all interface patch parameters in edit buffer can be modified by MIDI

CCs (see chapter 5.1.2.3) - it is possible to change them in a real time during playing the instrument (see fig. 5).

These changes are temporary only. lf necessary, new setting of the parameters can be stored in an user patch

SysEx message with the universal Device ID (7Fh) is always recognized by the interface independently on selected receiving MIDI channel.

During the interface reset, neutral values of the parameters are loaded into the edit buffer so that the interface doesn't affect the instrument.

This parameter is active only for MIDI Notes. It doesn't work with instrument's keyboard!

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 5.1.2.3.

The parameter value can be from 0 to 67. 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. 60. 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. 61. Etc.

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 24. The 0 value switches the pitch bend off – the Pitch Bend MIDI command is

ignored. The values of 1 to 24 are equal to bending the pitch in semitones. Bending up to ±2 octave is available

thus.

The individual patches stored in interface memory can be named - see chapter 5.3.2.

Since the interface does not have direct access to the control voltage of the tone generators, the tone is not detuned continuously but in semitone

steps. Together with the tuning changes, the envelope generators are re-trigged.

The parameter affects basic VCF cutoff

frequency set by VCF CUTOFF knob on

instrument's panel. It can be changed by MIDI

CC Nr. 18 - see chapter 5.1.2.2.

The parameter value is 0 to 127. For 64 value,

the VCF cutoff frequency isn’t affected. For

parameter values from 65 to 127, the VCF

cutoff frequency is increased and it is decreased

for parameter values from 63 to 0.

Remark:

Remark:Remark:

Remark: IIf you want to use full control range of

this CC, it is recommended to set the VCF

CUTOFF knob on instrument panel to the

middle position. Note that VCF fcM IN socket on

the Polysix’s rear panel is disabled when the

parameter is set to any other value than 64. A

pedal plugged to this connector is disabled in

this case!

This parameter is active only for MIDI Notes. It doesn't work with instrument's keyboard!

The parameter sets the modulation amount of the VCF cutoff frequency by MIDI Notes velocity. It can be

temporarily changed by MIDI CC Nr. 20 - see chapter 5.1.2.2.

The parameter value is 0 to 127. For 0 value, VCF isn’t affected by the velocity data, value equal to 127 provides

maximal modulation level (see fig. 8).

The parameter value is 0 to 127. For 64 value, VCF isn’t

affected by the Channel Aftertouch. For parameter

values from 65 to 127, the VCF cutoff frequency is modulated directly proportionally to value of MIDI Channel

Aftertouch. For parameter values from 63 to 0, the VCF cutoff frequency is modulated inversely proportionally

to value of MIDI Channel Aftertouch (see fig. 9).
