  • Page 5: Welcome

    I would like to thank Laurent Cartaux for his precious help on the SYNTHR4 skin. And I will finish my thanks for my wife and yes once again who let me have full freedom on long hours of development and tuning.
  • Page 6: Connections

    The MIDI converter can also be controlled by a MAO software. The Arpeggiator part and the Sequencer part of the SYNTHR4 will be able to receive a MIDI clock and the associated "Synch 24" commands via the DIN socket.
  • Page 7: First Visit

    FIRST VISIT SYNTHR4 consists of from left to right: • The oscillator section consists of 4 VCOs. VCOs 1 and 3 are identical as well as VCOs 2 and 4, they will be detailed later. • VCOs 1 and 3 each have a SUB oscillator and a Super SAW •...

    Continuously variable output: Triangle, Sawtooth, Pulse that can be controlled by the LFO2 or the modulation envelope. To perfect your knowledge of VCOs you can view the tutorial N°1, VCO at: Médias | SynthR SynthR4 - Tuto 1 : Les VCO - YouTube SYNTHR4 Manuel V1.06 EN Page 8...
  • Page 9: Mixer

    Between VCO1 and VCO2 or VCO4 measurable or between VCO3 and VCO2 or VCO4. See tutorial N°3 for this section: Médias | SynthR SynthR4 - Tuto 3 : Le reste de la façade gauche - YouTube MIXER • Each of the above sources can be sent to VCF1 and/or the VCF2.
  • Page 10: Filters

    - For some multimode filters, the mixing of modes is possible, for example LP and HP. This is valid for the so-called SVF or state variable filters. Other multimode filter will not allow this mixing. SYNTHR4 Manuel V1.06 EN Page 10...
  • Page 11: Modulations

    Sample & Hold sample rate potentiometer acting on any waveform in addition to noise. Make sure that this potentiometer is set to 0 when you are not using the S&H, otherwise the LFO will not function properly. SYNTHR4 Manuel V1.06 EN Page 11...
  • Page 12 This LFO can modulate LFO1 and LFO2 as well as the VCA panning. To perfect your knowledge of LFOs you can view the tutorial N°2, LFO at: Médias | SynthR SynthR4 - Tuto 2 : Les LFO - YouTube The envelopes are generated by digital integrated circuits associated with other components.
  • Page 13: Outputs

    The envelope potentiometer sets the opening level of the VCA. • The MIX potentiometer allows you to send the output of the VCA to outputs 1 (left) or 2 (right) of the synthesizer, to a mixing desk (line level). SYNTHR4 Manuel V1.06 EN Page 13...
  • Page 14 Tip: the more audio sources there are in the mixer when using the FX, the more you need to lower their input level in order not to saturate the effect. A position around 5 on the knobs is often sufficient. See tutorial #3 for more information. SYNTHR4 Manuel V1.06 EN Page 14...
  • Page 15: Use Of The Midi Controller

    USE OF THE MIDI CONTROLLER Now that you are familiar with the SYNTHR4, its analog part, its possibilities, we will go into the details of the MIDI controller and its different MENUS. The MIDI Controller is interfaced around a graphic display, seven illuminated push buttons and a rotary encoder.
  • Page 16: The Play Modes

    The filter envelope is sent to the 2 VCFs and the VCA envelope to the 2 VCAs. The Modulation envelope is free to use for FM, PWM, LFO2 destinations. The VCOS can be synchronized, at different octaves or detuned..SUB1 follows VCO1 and SUB2, VCO3 SYNTHR4 Manuel V1.06 EN Page 16...
  • Page 17: Paraphonic Mode

    The 4 VCOs are sent by default on channel 1. This can be modified by sending on channel 2 or a mix of the two channels. SYNTHR4 Manuel V1.06 EN Page 17...
  • Page 18: Arpeggiator Mode

    As long as a note is held, the arpeggio plays and can be modified. In this mode the audio sources can be sent to channel 1 or channel. Un appui sur SHIFT permet de supprimer ou activer les notes de l’arpège en cours à concurrence de 16. SYNTHR4 Manuel V1.06 EN Page 18...

    PATCHES The SYNTHR4 is a pre-wired modular synthesizer. That is to say that all the modules which compose it are internally linked by links activated by the memorable front panel buttons. It is thus possible to save, erase, copy and name a profile of buttons activated in a Patch.
  • Page 23: Parameters

    Activation of the Polychain mode. This mode allows, depending on the modes used, to recover the additional notes to 4 for example to send them to a SYNTHR3 or a SYNTHR4 or an Expander. The latter must be on MIDI channel n+1 with respect to the master synthesizer.
  • Page 24: Global Synthr4

    A communication software will be necessary: MIDI-OX (Windows) or SendSX (V4.0 or higher) (Windows) or Snoize (Mac) are utilities that manage sysex. All of them are freeware. The sending or receiving will be done only from the "SYSEX" page of the synthR4. It is not allowed to load sysex files 'on the fly' SYNTHR4 Manuel V1.06 EN...
  • Page 25: About

    In practice, create all the Patches and Sequences you want, then save the ones you want to keep via the send function. You can then delete or modify the Patches or Sequences on the SynthR4 knowing that you can return to the situation saved in the sysex file.

    VCO1 and 3 are sent to VCF1. • By default the internal clock will be on 120 BPM. • Sending of : All Note OFF MIDI • Sequencers are turned off. • Effects are turned off. SYNTHR4 Manuel V1.06 EN Page 26...
  • Page 27: Appendices

    APPENDIX 1 : MIDI KEYBOARD To take advantage of the SYNTHR4's features, the keyboard must have pitch bend, modulation wheel, aftertouch and velocity, as well as a sustain pedal, and be equipped with a 5-pin DIN connector. A keyboard equipped with only one USB plug can be used via the USB Host plug located at the back.
  • Page 28: Appendix 2 : How To Change Filter

    To replace another filter, align the connectors, if possible starting with the connector at the bottom of the card, then align all the contact points and push in the circuit, the cards must be aligned with the underlying silk-screen printing, then close the rear panel if necessary.

    The " Polychain " DIN socket (see above). APPENDIX 4 : EXTERIOR MAINTENANCE The wood of the SYNTHR4 is not varnished but waxed, which means that it is always possible to clean and re-wax it if the need arises. The color of the board is light oak.

    For all other multimode filters, even if mixing is allowed by construction on the first models, it is strongly discouraged. For example, on a JP6 type filter, do not press LP and BP at the same time. Reminder: All Low Pass filters allow only the LP button. SYNTHR4 Manuel V1.06 EN Page 30...
