Modulation & Random catch / sample & hold / 6 HP ⇣ Catch is a modular swiss army knife combining a great variety of useful functions in 6 HP modular width. 1/3 key features Stepped Random Generator Sample and Hold CV Clock Generator Attenuverter Offset Noise Source LED indication Skiff friendly Wrong polarity protection specs & downloads width: 6 HP depth: 28 mm power: 38 mA @ +12V / 27 mA @ -12V documentation videos description / manual Catch serves as a modular multitool, integrating a diverse range of valuable functions: Stepped Random Generator Sample and Hold CV Clock Generator Attenuverter Offset Noise Source On top of the module you will find the clock generator with its speed potentiometer. Turning CW will increase the speed of the clocks generated. The speed range can be altered with the ON-OFF-ON switch and CV controlled via the CV jack. The clock signal is forwarded to the CLOCK OUT and to the internal Stepped Random Generator and Sample and Hold circuit. If nothing is patched into the TRIG IN jack, the clock triggers the Stepped Random Generator and provides a random voltage on the C/OUT jack. This connection will be cut in case of an external trigger signal being patched to TRIG. In case of a voltage being patched to IN, this source will be sampled and caught on trig on the C/OUT jack. Either the external or the internal voltage signal can be offset and attenuverted and will be supplied on the A/OUT jack, The left bicolor LED indicates the current voltage being adjusted by the offset and attenuverter and the right bicolor LED shows the random voltage being caught on internal or external trigger. If you patch OUT into your audio path, you will hear very warm white noise. prev Up next

Utilities & PSU once in a while / 3-channel mono, 1-channel stereo CV click-less mute / 6 HP ⇣ Tired of muting with all the drama of a Shakespearean tragedy? Say goodbye to the click drama with our click-less mute module. It's like giving your modules a chill pill – no more dramatic exits, just smooth audio bliss. 1/4 key features 3-Channel Mono Mute 1-Channel Stereo Mute Click-Less Muting based on Vactrols STRIKE Buttons for Performance Mutes LED Indication MUTE or GATE Mode for Channels 1-3 Wrong polarity protection specs & downloads width: 6 HP depth: 35 mm power: 25 mA @ +12V / 14 mA @ -12V documentation videos description / manual ONCE IN A WHILE is a 3-channel mono and 1-channel stereo mute switch with CV control. Any audio or CV signal fed into the IN jacks and taken from the OUT jacks can be muted and unmuted with a latching MUTE button per channel. If a channel is not muted, you can also mute it momentarily with the dedicated STRIKE button. Conversely, you can unmute a mono channel with the same STRIKE button if it is muted (this is not possible with the stereo channel). LEDs indicate whether a signal is being passed. You can also use CV signals to mute channels. Just connect a gate, LFO or envelope to the CV inputs and the channel will be muted from a voltage of about 2 volts. Even if you apply a control voltage to the CV inputs, you can mute the signal with the MUTE (latching) or STRIKE (momentary) buttons. Before soldering the module, you can decide if you want to use one of the mono channels alternatively as a low-pass gate. It's a single resistor you need to change and a mono channel becomes an LPG when a CV signal is patched into its CV input. So if the channel is muted, it will be unmuted again when the CV input is high. Mute mode = CV mutes the signal when it is not muted. LPG mode = CV unmutes the signal when it is muted. The first input is normalized to the other inputs. Therefore, you can also use ONCE IN A WHILE as a 1 to 4 buffered multiple with individual mute switches. ONCE IN A WHILE was designed to provide click-free muting for audio signals, but has become much more performance-oriented with the addition of momentary STRIKE buttons and CV inputs. It was optimized to be used with the VTL5C9 Vactrol. You can also use other vactrols, but then you may get clicks when muting audio. prev Up next

Utilities & PSU pedal pal / efx pedal audio bridge & expression pedal module / 4 HP ⇣ Pedal Pal is your way to use guitar effect pedal s with the Eurorack Modular System. 1/3 key features Mono Send with Attenuation Stereo Return with Gain for each Channel Output Gain of max. +20 dB Expression Pedal Control (CV or Manually) Voltage limited to 3V or 5V adjustbale via Jumper Wrong polarity protection specs & downloads width: 4 HP depth: 28 mm power: 25 mA @ +12V / 21 mA @ -12V documentation videos description / manual PEDAL PAL features a mono send with pedal attenuation and a stereo return with individual channel gain adjustment from the pedal. You can fine-tune attenuation and gain through trimmers located on the module's back. Furthermore, it doubles as a CV expression pedal using a TRS cable. You have the option to manually manipulate your effect pedal's parameters by plugging into its Expression In jack, akin to using an expression foot pedal. Alternatively, you can employ any CV source (like an LFO or Envelope) to automate effect adjustments. When external CV is applied, the potentiometer functions as an attenuator. The CV delivered to the pedal's expression in jack can be constrained to either 3V or 5V, adjustable via a jumper on the rear. It's important to note that CV control over effect parameters will only function if your pedal includes an expression pedal TRS input. To establish connectivity between the module and your stereo effect pedal, three 6.3/3.5 mm adapter cables and a 6.3 mm TRS cable will be required. prev Up next

Utilities & PSU cv expert / dual polarizer, offset & gain with LFO / 4 HP ⇣ CV EXPERT is a very compact yet powerful CV tool that is equipped with all the important functions you need to customise your control voltages. With its internal LFO, it is immediately ready for use without further patching. 1/3 key features 2x Polarizer 2x Offset 2x Gain Triangle or Square Wave LFO Internal normalizations Low HP format Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 50 mA @ +12V / 32 mA @ -12V documentation videos description / manual CV Expert (Cve) is a versatile dual-channel tool for customizing control voltages. Its internal LFO is normalised to both inputs and allows you to choose between a triangle or square wave via a jumper on the back. The LFO connection is automatically interrupted when an external CV is inserted. Adjust the LFO rate with the LFO RATE potentiometer. The signal received at the DC-coupled inputs IN ① and IN ② passes through three CV tools: Polarizer The PLRZR potentiometer enables voltage attenuation and inversion. At the midpoint, the signal is eliminated. Turning to the right allows the original voltage to pass through (as with an attenuator). Turning to the left inverts the signal, e.g. positive signals are converted into negative signals. Offset Adds or subtracts voltage from/to the passing signal. OFFSET control determines the offset range. In the center position, there is no voltage offset. Turning the control to the right shifts the voltage to the positive range, while turning it to the left shifts it to the negative range. Gain Amplifies the signal with a maximum gain of 2 at the GAIN control's maximum position, effectively doubling the applied voltage (e.g., +1V becomes +2V, +3V becomes +6V, or +4V becomes +8V). The voltage is capped at a maximum of +/-10V. CV EXPERT QUICK START GUIDE: CVE_QUICK_START .pdf Download PDF • 422KB prev Up next

Filter & EQ natural state / dual envelope ducking filter / 16 HP ⇣ Natural State consists of two 24db filters with a CV decay envelope and an internal LFO. It is designed to filter two waveforms in the most ear-friendly way possible to create natural and organic sounding grooves and soundscapes. 1/3 key features Dual Filter Dual Envelope Decay CV Filter CV Filter Ducking Internal LFO normalized to Filter CV Envelope Output Slider Pots Wrong Polarity Protection specs & downloads width: 16 HP depth: 28 mm power: 81 mA @ +12V / 55 mA @ -12 documentation videos description / manual Each of the two channels has a DECAY slider that adjusts the decay length, an OPEN slider that adjusts the filter cutoff, and a FORCE slider that adjusts the amount of decay CV that affects the filter. The STRIKE input takes any CV from +1 volt and triggers the decay envelope. Both the decay and the filter cutoff can be controlled via the CV inputs DECAY and CTRL. Attenuators can be used to change the strength of the applied CV. The decay attenuator also acts as a DECAY CV offset. A subtle internal LFO can be routed to the filter cutoff, which is attenuated with the CTRL controls. The LFO range is rather slow to create smooth filter sweeps. The resonance of the individual filters can be changed with the PEAK potentiometers. When the DUCK control is turned to the right, the decay of the left channel increasingly suppresses the signal of the right channel, creating a ducking effect. Both decay envelopes are also routed to the ENV sockets for further external processing. NATURAL STATE QUICK START GUIDE: NATURAL_STATE_QUICK_START .pdf Download PDF • 764KB prev Up next
