The new version is an excellent entry-level module, and at the same time a real

Swiss army knife. It was made to change the way you interact with your

sequencers, controllers, DAWs, and other MIDI gear. This powerful module

features both MIDI input and output, USB type-A host, and USB type-B inputs

combined with a vast number of configurable CV outputs. By using the Smart

Thru option, you can daisy-chain multiple Poly 2 modules together for even

more voices and outputs.

Inputs and outputs

Introduction

Poly 2 module is a polyphonic MIDI to CV converter with MPE (Multidimen-

sional Polyphonic Expression) support. It's the second version of the legacy

Poly. We have revised it thanks to smart user requests. We have also managed to

make it smaller. The new dimensions are 14HP wide, 24mm deep. Poly 2 is still

intended to be as simple to use as possible. Now equipped with an OLED screen,

paired with a clickable encoder, Poly 2 allows you to change its settings easily

and configure it exactly as you want. It also offers you a way to save and recall

your setting for different usage scenarios.

Poly 2 offers 20 configurable outputs of which 8 are factory calibrated - Pitch1-4

and CV5-8. Their accuracy in the majority of range (excluding the extreme high

and low values) is ranging from 2.5mV to 5mV. The used DAC (digital to

analogue converter) is a 12bit type. That's why the pitch-bend is mapped from

14bit to 12bit. The remaining outputs are not calibrated, but still, their accuracy

is around 20mV.

In terms of outputs, Poly 2 is offering some smart features as well. Its all three

inputs can be used simultaneously at the same time. In a case where three

identical MIDI messages are sent from three independent sources (MIDI

Input/Host/USB), the first one to reach the Poly has the priority.

Voices

Poly 2 can handle up to 8 voices, which are CV Gate and Pitch pairs. If the

number of total voices is higher than 4, then CV1 becomes the 5th Gate and CV5

becomes the 5th Pitch. Analogically CV2 is Gate 6th, CV6 is Pitch 6th, etc.

To choose the number of voices, click the encoder, go to Voices and set the

desired value.

The number of occupied voices determines the remaining configurable outputs.

The system allows you to configure only the non-occupied outputs. For

example, if voices are set to 7, then configurable CVs are CV4, CV8 and CVs from

9-12.

Play modes

Poly 2 can work in four different play modes: First, Next, Channel and Notes.

In the First mode, you can send MIDI values to one or more of outputs. Let's use

a keyboard controller as an example. The first key pressed (the first note sent)

occupies the voice number one. While the first key remains held, the second key

pressed activates the first available voice.

The Next mode works as voices do in most polyphonic synthesisers. When

MIDI note is sent, then the system looks for next non-occupied voice and

triggers it. Each MIDI Note on and off message scrolls through all available

voices.

The Channel mode translates the data received from MIDI Channels 1-16 and

directs them into the corresponding voices. This mode is what the majority of

users utilise to connect DAWs or external sequencers.

If Channel mode is selected, you'll see "Channels" displayed in the menu. In this

setting, you can indicate which voice is triggered with which MIDI Channel.

By default, the number of voice is equal to the number of MIDI Channel.

In the Notes Mode, Poly 2 translates data received from MIDI Notes C through

G and directs them into the corresponding voices (no matter the octave).

This scenario works excellent for triggering drums from drum pads or drum

triggers. When Notes mode is selected, you'll see "Notes" occur in the menu.

In this setting, you can indicate which voice is triggered with which MIDI note.

By the default the first voice is set to C, voice two is C#, voice three is D, voice

four is D# etc.

Custom CVs

Dependently from the number of selected voices, there are several configurable

CVs at your disposal. To set them, go to "Custom CVs" menu and pick the desired

output:

Velocity

MIDI Velocity is related to MIDI Note ON message. Here you can set which voice

is related to the selected Gate output.

There are two options: MIDI Channel or CC number.

• Channel – allows setting which MIDI Channel translates all of the CC

messages. There are several sub-settings:

• Specific – CC messages are transmitted only from the chosen MIDI

Channel,

• All – transmits all CC messages from all MIDI Channels,

• Voice – translates all CCs but only for the chosen voice.

• CC number - allows you to specify CC number from which the values are

transmitted.

Note: Set CC to Voice when you want to use Poly 2 with MPE compatible devices.

• Root note – sets the scale root note.

Config

Middle C

Ranges from C3 to C6 and allows you to choose the middle C note convention.

If Poly 2 is converting the incoming MIDI Notes to a different octave than the

ones received, this means that the transmitting device has a different middle C

convention setting. Here you can align the octaves.

Clock

This setting allows you to translate the incoming MIDI Clock signal to the

chosen output.

Note: You can set the value of voltage being sent when MIDI Clock is received

(0-5V or 0-10V) in Config Menu > Gate > Voltage.

• Multiplier – the standard MIDI message send 24PPQN (Pulses per quarter

note). In Eurorack world most module's clock operates on 4PPQN.

The value of Multiply can change the clock conversion rate.

Start/Stop

Sets the chosen output to convert the MIDI Transport values into Gates.

Note: You can set the value of voltage being sent when MIDI Transport message

is received (0-5V or 0-10V) in Config Menu > Gate > Voltage.

Off

It's sometimes useful to turn off the out-coming signal.

Scale

Thanks to the implemented scales filter, Poly 2 outputs only the notes that are

within the scale. If the note is not in the scale, the system looks for the closest

note that fits. It might be helpful to achieve musical results without a degree in

Music Theory.

There are two settings:

• Type – a selection of 39 scales filters. You can find the list of the musical

scales in the appendix.

Load/Save profile

Store and recall all your user settings made for different setups and different

scenarios.

Note: Besides the ability to save and load the parameters, Poly 2 autosaves the

current configuration and recalls it when the module is toggled on.

Note: An excellent example of different Middle C conventions are programs like

Apple Logic and Ableton Live (MIDI Note C2 is not the same value as C2 in Ableton

Live).

Gate

• Voltage – changes the values of the transmitted volts for the Gate, Clock

and Start/Stop parameter.

• Reverse – changes the phase of the Gate outputs voltage.

Pitch

Sets one of the three pitch conventions: V/Oct, Hz/V, Buchla standard

(1.2V/Oct).

MIDI output

• Smart thru – allows you to daisy-chain multiple Poly 2 units to expand the

number of voices and outputs. It passes thru all the information that is not

utilised by the unit within the current setting to the MIDI output.

• Thru – passes all the incoming information to the MIDI output.

Pitch-bend

• Auto – if the transmitting instrument is sending out information about its

MIDI Pitch Bend setting, then the Poly 2 set to Auto automatically adjusts.

• Off – Poly 2 bypasses all the transmitted pitch bend related information.

• +/- 1-6 Oct – if the source instrument isn't sending the Pitch Bend

information by itself, you can set it manually in a range of 6 octaves up and

down.

CC/CV Smoothing

Depending on the setting (Off, Low, Mid, High) all your CV outputs that are

converted from CC messages can be smoothed out.

Gate view

Displays the outgoing triggered voices – beneficial to monitor that messages

Panic!

Sometimes MIDI information can get stuck, use the Panic! Function to release

all the voices and reset the MIDI information status.

Exemplary scenarios and recipes

Use DAW or hardware step sequencer to operate your modules

Connect your computer/sequencer with a USB cable or MIDI cable using MIDI

interface. Set Play mode to Channel. Now set your sequencer, so each track

sends different MIDI Channel. There you have it, you've just made you Eurorack

groovebox.

Use acoustic drums to trigger your modules

Connect drum triggers to your kit. Connect the kit to Poly 2 with USB or MIDI

cable. Set Play mode to Notes. Set custom CVs to Velocity. Now connect the

module outputs with your Eurorack drum (or non-drum) modules.

Make polyphonic synth with your modular setup

Connect your MIDI keyboard to Poly 2 with MIDI our USB cable. Set Play mode

to Next. Set Custom CVs to Velocity and CC (CC number set to 1 will transmit the

information from Modulation Wheel of your controller).

Play expressively using MPE device with your modules

Among many others, there is an iPhone/iPad app that suits perfectly to the Poly

2. It's called Ribn. Once you have the app downloaded, connect your smart-

phone/tablet to the module using a USB cable (in some cases the Camera

Connection Kit is needed). Then set the Play mode to Channel and Custom CVs

to CC number. In the app set the Channels and CC numbers adequately to Poly 2

settings. The app records and recalls up to 8 values motion that Poly 2 will

convert to the voltages. Great way to liven up your setup.

Control your envelopes and LFOs with your smartphone

Connect your MIDI MPE device to Poly 2 with MIDI or USB cable. Set Play mode

to Next. Set Custom CVs to Velocity and CC (CC number set to 74 will transmit

the information from "the third dimension" of your controller). Set CC to

Channel>Voice.
