Page 4: Welcome
And I will finish my thanks for my wife who gave me complete freedom on long hours of development and tuning. The very small company SynthR SAS was born from this project in order to support you as best as possible. -
Page 5: Connections
The MIDI converter can also be controlled by a DAW software via the USB port. The Arpeggiator part and the Sequencer part of the SYNTHR3 will be able to receive via the DIN socket a MIDI clock and the associated "Sync 24" commands. -
Page 6: First Visit
FIRST VISIT The SYNTHR3 consists from left to right of : The oscillator section consists of 3 VCOs. VCOs 1 and 2 are identical except that VCO2 can synchronize with VCO1. VCO3 does not have a PW modulation section, but has an additional waveform, it can synchronize to VCO1 as well and above all can be transformed into an LFO (LFO1). -

Keyboard tracking 0 to 120%. 100% is between 8 and 9 sign pot. Dedicated Envelope Input Adjustable modulation input 1: LFO1 or LFO2 or S&H. Adjustable modulation input 2: Aftertouch or Modulation wheel SYNTHR3 Manuel V1.01 EN Page 8... - Page 9 * * * Note: The proposed filters are based on known schematics, but are by no means clones of the components. It is therefore possible that some of them do not have the grain, the fineness, the harmonic range or even the known defects of these famous filters. SYNTHR3 Manuel V1.01 EN Page 9...

LFO trigger button by Aftertouch SYNTHR3 Manuel V1.01 EN Page 10... - Page 11 Note : MIDI keyboards with aftertouch have the possibility to have several curves. If your keyboard is set to a linear curve by default, the SYNTHR3 will force this curve to become exponential in order to increase sensitivity. Knob for triggering the LFO with the Modulation Wheel.

VCF2 and the Gain potentiometer of the VCA2 is used for the output level. It is preferable in this case to set it to full. The envelope potentiometers do not act. SYNTHR3 Manuel V1.01 EN Page 12... -
Page 13: The Play Modes
The filter envelope is sent on the 2 VCFs and the VCA envelope on the 2 VCAs. The Modulation envelope is free to use for FM, PWM, LFO2 destinations. VCOS can be synchronized, at different octaves or detuned ….. Reminder: SUB follows VCO1 This is still a bi-timbral play since each channel has its own VCF and VCA. SYNTHR3 Manuel V1.01 EN Page 13... -
Page 14: Monophonic Mode Serial Filter
However, nothing will be output through VCA1 and all the audio will be output through VCA2. As the filters can be identical (2 low passes) or different, this mode allows you to sculpt a finely tuned sound thanks to the action of the 2 successive filters. SYNTHR3 Manuel V1.01 EN Page 14... -
Page 15: Duophonic Mode
In this two-tone duophonic mode the VCF1 and VCA1 together receive the modulation envelope. Be careful to open this envelope otherwise there will be no sound. As for VCF2, it always receives the filter envelope and VCA2 the VCA envelope. SYNTHR3 Manuel V1.01 EN Page 15... -
Page 16: Paraphonic 1 Mode
The lowest note has priority and will be played by VCO1, the second pressed note will be played by VCO2 and the third by VCO3.. The choice of filters is free. Tip: Tuning the 3 VCOs in unison but above all not synchronizing them. SYNTHR3 Manuel V1.01 EN Page 16... -
Page 17: Paraphonic 2 Mode
Mixer. Finally in this mode, the VCF2 receives on its envelope input an analog OR of each of the note envelopes. The filter can therefore react on each played note. SYNTHR3 Manuel V1.01 EN Page 17... -
Page 18: Arpegiator Mode
The detailed use of this mode is covered later with the use of the MIDI controller. CONTROLLER MIDI USAGES Now that you have gotten acquainted with the SYNTHR3, its analog part, its possibilities, we are going to go into the details of how its brain works: the MIDI controller and its different MENUS. -
Page 19: Midi Controller Functions
MIDI CONTROLLER FUNCTIONS A control screen of 4 lines by 20 characters allows to use the SYNTHR3 by three commands located below the screen: The first three lines always concern the current action and / or mode, the fourth line specifies the momentary role of the commands located below. -

Indeed as explained above the 2 VCOs being independent of CV and Gate, either the VCO2 lives in couple with the VCO1 or it lives as a single. There are 10 possibilities for him: SYNTHR3 Manuel V1.01 EN...

- Page 23 STEP SEQUENCER MODE The Step Sequencer of SYNTHR3 respects the modular nature of SYNTHR3. As on physical sequencers, a clock is running and at each step a note or a chord or a silence is played. A note can be repeated on the principle of "Ratchet" in sixteenth notes, thirty-second notes or sixty-fourth notes.

- Page 25 This mode is actually an extension of the Duophonic mode. By connecting a MIDI cable (Din 5 pins) between a SYNTHR3 called number 1, via its " Polychain " jack and a SYNTHR3 called number 2 via its MIDI IN jack, we create a synthesizer with 4 polyphonic notes and 4 timbres.

Advice: The A 440 Hz heard is sinusoidal because it is passed through a filter. Put the SYNTHR3 in monophonic mode, put on each VCO the triangular waveform without any modulation, set to octave 0, put the VCF1 completely open (Cutoff on 10, resonance on 0) and send successively each VCO via its switch on the VCF1 and adjust the beats by ear. - Page 28 PATCH The SYNTHR3 is a modular synthesizer. That is to say, all the modules that make it up are independent of each other. VCO, VCA, VCF, MIXER, etc. all these modules are governed by the 1V/octave standard In a historical modular synthesizer, the patches are the cables that connect the modules together. For SYNTHR3, no cables, but push buttons that connect the modules together.

Turn the potentiometer, the above screen will appear. The values indicate the difference -67mv 420Hz between the LA4 440Hz and the tuning of the SYNTHR3 in different units. To go back to the -800cents original screen, press " Escape " (Button B) or wait a few seconds and this Mastertune Escape screen will be erased to automatically return to your original page. -
