Patching Panda – Punch MG – Full DIY Kit

Punch MG is a unique mixer module with built in VCA-Decay & Decay Muting Groups. This module has been specially designed to generate dynamic percussive sounds while also offering the capability to manage multiple signals simultaneously through its innovative mute group feature.

Key Features:

  • Mute Group Interaction and Signal Patterning: Utilize the mute group feature to enable interactions between signals that share the same group.
    This feature enables signal muting and amplitude limitation when multiple signals are triggered simultaneously. The amplitude and decay time of each
    signal are influenced by others in the same group. This characteristic can lead to captivating pattern variations when focusing on specific channels.
  • Envelope outs: Each envelope’s polarity can be inverted using dedicated switches on the front panel, enabling you to achieve effects like side-chain compression and ducking. Also, the mute group circuit’s influence extends to the envelope signal output, providing intriguing modulation capabilities that add a unique layer of creative expression to your sonic endeavors.
  • AM Sound Creation: Connect audio rate signals to the level input to explore the creation of AM (Amplitude Modulation) sounds, further extending the sound design possibilities.
  • Expandable Capability: By linking two modules, you can expand the effect of the mute group to accommodate up to eight signals, fostering intricate
    interactions and captivating sonic landscapes.

Patching Panda – Operat – Full DIY Kit

Operat is a highly functional, analog oscillator with a multitude of blendable modulation features, making it a module that is just as good as a collaborator as it is a solo module. Starting at its core, Operat offers four basic waveshapes that are blendable via an internal mixer, offering a sine, triangle, saw, and square wave.These waves not only have their individual output, but they additionally have their own individual mixer with CV inputs for introducing complexity at an early stage—use it as a VCA or for amplitude modulation! Additionally, the square wave’s pulse width can be modulated via the PWM control and CV input, with three different flavors to choose from for adding variety to your standard PWM. These and other forms of modulation can be heard in Operat’s fullest extent via the Mix output.

The real magic starts when introducing external modulation to any of Operat’s many CV inputs, offering a wide range of timbres – great for basses, leads, and anything you can think of. The Sync input can act as hard or soft sync to force Operat to any other oscillator’s base frequency, a desirable effect to modulate with the additional exponential FM input. Modulate the internal mixer’s final output with either amplitude or ring modulation for metallic timbres, and a blendable dry/wet control allows you to determine how much of the effect is heard.

More brilliance comes into play with the selectable frequency or phase modulation, producing a wide range of tones that can be introduced with the symmetry parameter, offering subtle sonic shifts to in-your-face aggression. Introducing the Thru-Zero parameter will start to invert the waveform, depending on the positioning of symmetry, and this applies to both FM or PM for maximum harmonic manipulation. Operat can act as a VCO or LFO, making it just as great of a tonal source as much as a modulation source!

FEATURES

  • Analog thru-zero oscillator
  • Four individual waves (sine, triangle, saw, and square) with internal mixer, individual levels and CV control for each
  • Mix output for blended mix of all four oscillators
  • PWM control and input with three selectable configurations
  • Amplitude or ring modulation from the internal mixer, including a dry/wet control to blend with original signal
  • Sync input with selectable hard or soft setting
  • Frequency or phase modulation with bipolar symmetry control
  • Thru-zero control to introduce inversion of the FM or PM effect
  • Exponential FM input and 1V/Oct tracking input
  • Width: 12HP
  • Power consumption: 119mA@+12V, 85mA@-12V

Patching Panda – Moon Phase VCF – Full DIY Kit

All SMD parts come pre-soldered!

The Moon Phase is a Stereo 12dB/octave state-variable multimode filter with a powerful imaging technique to enhance and alter the stereo field. Patching a single signal into the left input will run it through both filters, but a separate right input is available for processing an existing stereo signal path or two separate mono signals. A single frequency knob will set the base cutoff point for both filters, with a span control that will spread both peaks further apart in either direction.  Moon Phase features eight different filtering modes. Each of the eight modes will switch between various combinations of filter types for the left and right channels, such as Dual Lowpass, Lowpass/Notch etc. (see manual for more details). There is also a CV input for mode which allows for stepping through filter modes like a sequential switch, things can also get wild when feeding this input audio rate signals. Unlike many other filters, Moon Phase does not self-oscillate with high resonance settings. When the resonance control is pushed to maximum it will distort and modify the sound in other ways. The resonance behaviour is always affected by the Stereo Imager control, which applies phase shifting and can add distortion and other interesting artefacts into the sound.

Patching Panda – Ephemere – Full DIY Kits

Ephemere is a two-channel, voltage-controlled buffer for recording and playing back CV signals such as LFOs, envelopes, trigger patterns, or sequences. Each independent channel features latching play and record buttons, as well as a stop button that can also function as a panic control. The Play/Reset and Record functions can also be addressed by external clocking signals for synchronized control, rhythmically bringing the Ephemere into step with any patch. Playback speed and playhead starting position can be adjusted manually or with external CV, allowing you to scrub through your control signals with a level of dynamism and flexibility typically reserved for audio signals.

Optimized for recording control voltages, buffers of up to 1014 seconds are possible when running the Ephemere at its lowest sampling rate of 172Hz. Full-spectrum audio signals up to 4 seconds in length can be stored and recalled when clocking the module at 44.1kHz, which means the Ephemere can also function as a two-channel looper or pair of one-shot samplers. When nothing is patched to a channel’s input, the corresponding Input knob can be used to generate manual CV signals which can be recorded and played back.

With an SD card, up to 16GB of storage is available for storing and recalling your control and audio signals, allowing you to save your favorite cuts between sessions. An intuitive OLED display shows the contents of the buffer for the currently selected channel, as well as the playhead position, providing immediate visual feedback.

With its intuitive interface and extensive CV control, the Ephemere provides a performance-ready, powerful tool for recording and manipulating almost any signal in your modular system, from subaural sequences, to audio signals, and everything in between.

Patching Panda – BD-Z – Full DIY Kit

BD-Z is a versatile kick drum module for Eurorack in 12HP. The BD-Z is able to produce a wide range of bass drum and percussive sounds, that go further than the typical 808 and 909 styles.

Patching Panda have implemented thru-zero FM/PM for an immense variety of textures and harmonics. The module also features a great amount of CV inputs for modulation, to shape the sound, transform and morph it into many other drums sounds like bongos, congas, etc.

The circuit was carefully designed to maintain the signal gain, regardless of the setting – it will always be punchy and when the amplitude decay or the distortion is fully open it won’t get out of control.

The distortion can be subtle or aggressive, and BD-Z  has a dedicated accent input like some vintage drum machines to add dynamics to the rhythms. Another useful addition are the two amplitude envelope outputs. These allow you to send positive and negative envelopes out to interact for other modules to interact with the BD-Z. Perfect for setting up a side-chain patch with a VCA.

FEATURES

  • Analog kick drum module
  • Manual and CV input triggering
  • Separate amplitude and pitch decay controls, both with CV inputs
