Polyphonic Synth VoiceBread & Butter is a General MIDI based polyphonic synth voice with 128 selectable instruments plus a drums preset. The sound banks have a synthetic and warm quality to them, and the variety of instruments makes this module a flexible and fun addition in any system.Bread & Butter features the standard V/OCT and GATE inputs for triggering the synth voice. Thanks to a polyphony of up to 64, the voices will decay independently making it possible to ratchet chords that decay polyphonically. If the HOLD function is engaged, each note will also sustain. In addition, the MIDI input can be used simultaneously with the V/OCT and GATE inputs. For example; trigger the drums on MIDI channel 10 while generating a bass line via the V/OCT/GATE inputs. The synth voices can also be played polyphonically via MIDI.The module features stereo outputs and the PAN knob lets you spread the polyphonic voices out in the stereo sound field. Parameters such as pitch bend, velocity and instrument selection can be voltage controlled.Features:• CV input range: +/- 5V• Gate input voltage: 3,3-10V• Polyphony: Up to 64 voices (40 voices with sustain)DIY-Kit-Type:SMD-Kit-1.

EUCLIDEAN is a gate sequencer for the Eurorack format based on the euclidean algorithm. It is based on the euclidean DIY module developed by Music Thing Modular’s Tom Whitwell, and he has blessed this module with his approval.The module consists of three channels of sixteen step sequences, and each channel can be set to any length, density and offset between one an sixteen. You get clear visual feedback due to the 8×8 matrix LED display, and setting each channel is easily done with the three encoders.EUCLIDEAN is perfect for creating polymetric rhythms, odd time signature sequencing or clock division with a twist.The module runs an internal clock set to 120 BPM by default, but can be triggered and reset externally. Each sequencer channel has a dedicated trigger output. In addition, the first channel has an inverted output that outputs triggers on every offbeat.Trigger output voltage: 5VDIY-Kit-Type:THT-Kit-1.

MUTE || VCA x6 might not be the smoothest of module names, however this module is a utility gem that packs a lot of punch per HP. In essence, MUTE || VCA x6 is six clickless and DC-coupled mute channels in 8 HP that can be used for muting virtually any signal within a Eurorack system. Each mute channel can be set on or off either by pushing the corresponding illuminated switch or by feeding it any signal that goes over +1 volt above ground.Six channels of mutes is surely a great thing, but what if you could configure each channel to be either a MUTE or a VCA? This module allows you to do just that! –(And this is also where the name comes from; || meaning OR)– On the back of the module there are six switches, one for each channel, and these can be set to either MUTE or VCA. This means that the module can be configured to any combination of MUTES and VCAs you wish. In VCA mode the CV input offers linear CV control over the VCA. The switch adds +5V to the CV input if it is activated, effectively making it possible to switch the CV input between bipolar and unipolar behaviour which is very handy when controlling the VCAs with LFOs.The inputs are also normalled against each other through the switched jacks, so connecting a signal into the first input cascades it to all other channels. This is perfect for sending one sound to different effects, or distributing a clock to several modules and having the option to turn the clocks on or off dynamically.Finally, with the mute switches laid out in a row to the right makes this perfect to mount to the rightmost edge of any Eurorack live system, enabling easy access to the mute switches during a live performance. All in all, this is by far the most flexible and feature packed module in the Sebsongs Modular “x6” utility series of modules!DIY-Kit-Type:SMD-Kit-2.

ODDS is a generative melodic looping sequencer for the Eurorack format. It generates notes based on random probability, and it is designed to be as musical as possible while maintaining a direct and minimalistic interface. It enables you to set a probability to generate random notes within a given octave, scale and chord structure.The module can via the LOOP switch either be set to indefinitely generate random notes, or be set to loop the last up to 64 steps. The V/OCT input acts as transposition within the chosen scale, making it easy to create chord progressions.Gate output voltage: 5 VCV output voltage range: 0-7 VDIY-Kit-Type:SMD-Kit-2.

OFFSET x6 is the perfect sibling to the ATTENUVERT x6 - six DC offset channels in a slim package!The module consists of six inputs, six outputs and six knobs. Each offset channel can offset AC or DC signals with +/- 5V DC. Without any signal connected to the inputs, the outputs generate adjustable +/- 5V DC voltages, which for instance could be handy for offsetting v/oct inputs on a VCO.OFFSET x6 is a very useful utility module for tuning in DC offsets for modulation. Many digital modules only accept unipolar modulation (only positive voltages), and many modulation sources are bipolar (positive and negative voltages). OFFSET x6 makes it possible to “shift” the +/- 5V signal from an LFO to instead being a 0-10V signal. Use it in conjunction with ATTENUVERT x6 to also shape the amplitude and polarity of your modulation sources.DIY-Kit-Type:SMD-Kit-2. This is a Do-It-Yourself kit, not an assembled module.

Designed with performance in mind, POLYSEQ delivers a flexible polyphonic step sequencing workflow. Any of the 8 memory slots can be programmed via external CV/GATE up to 64 steps in length. In playback mode, any of the three outputs can play back from any memory slot, making it possible to create polyphonic and polymetric sequences with low effort. POLYSEQ can be clocked internally with swing or externally via the clock input.Polyseq can be clocked internally (5-300 BPM) or externally. The internal clock has swing from 5 to 95% (Hold MODE and adjust the tempo pot).Beside CV and GATE, sequences can have rests, ties and glide. There’s also a skip function which steps forward in the sequence without overwriting anything. This is handy for editing sequences or changing the sequence length. Each channel can do forward, backward, ping-pong and random playback (Hold MODE and press channel switch to toggle through the modes). Each playback channel can also be clock divided from 1 through 8 (Hold MODE+CH and adjust the memory division rotary switch). Finally, each channel can be individually muted (Short press on channel switch, latching).DIY-Kit-Type:SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module.

The Sebsongs Modular Sampler DIY kits are now coming with presoldered surface mount components, making the DIY kit faster and easier to build.The Sebsongs Modular SAMPLER is an intuitive 12 bit audio recorder and manipulator designed for short loops and one shots. Sounds can be recorded either with the built in microphone or a mono input jack, which can handle anything from a regular laptop or smartphone to modular level signals. The SAMPLER has granular control of the recorded audio and you can play around with pitch, forward and reverse, start position and loop length (or connect cv/gate to any parameter) to open up a world of interesting sounds!The SAMPLER can be used in looping mode, where for instance time stretch like effects can be obtained easily by modulating the start parameter, or in one shot mode where the reset input is used to trigger playback of the recorded audio and the SAMPLER can function as a drum sample player.The maximum recording length is around 3.5 seconds in the highest sample rate (pitch control fully forward or reverse). If you lower the pitch you get longer recording time. Change the pitch while sampling to obtain pitch fluctuations and tape stop effects.Sound can be recorded either with the built in electret microphone or via mono input jack*. The audio input has enough gain for amplifying regular laptop or smartphone headphone outputs, and the input can also handle modular level signals.* If connecting stereo signal from a laptop / smartphone via either TS or TRS mini jack cable it is advisable to pan the source fully left to avoid distortion.DIY-Kit-Type:SMD-Kit-1.
