There is also an individual EQ available. The volume of the channels is adjustable with the two VOL potentiometers. The output of each channel is supplied on the L and R output jacks. These can be used for stereo signals. You may use CV Pan to change the volume of each side. Turning the CV Attenuator you sets the amount of PAN applied to both channels. Additionally there is a MIX out, where both sides are available at a single output jack. Using the Pan knob or the CV IN you can pan between both sides. If there is only one audio source connected to IN L this signal is multiplied to the other channel in order to provide a crossfade functionality. prev Up next

pedal pal stereo / fx pedal integration module / 8 HP ⇣ Enhance your creative palette by seamlessly integrating your favorite guitar FX pedals into the realm of Eurorack modular. Take command over the amount and tone of the signal sent to your pedal and manipulate the expression pedal input using CV. To double the excitement, this module can handle stereo signals! 1/3 key features Stereo FX-Pedal Integration Expression Input CV Send CV Send and Return Level Controls Send Tone EQ Dry/Wet Control TRS Connections to FX Pedal Use it with Line or Modular Levels Boost Dry and/or Wet Signals with a max. Gain of +20 dB Phase Inversion Switch Skiff friendly Wrong polarity protection ​ specs & downloads width: 8 HP depth: 30 mm power: 59 mA @ +12V / 43 mA @ -12V documentation videos description / manual Connect a stereo or mono signal to the IN sockets (a mono signal to IN L is normalized to IN R), and retrieve the output signal from the OUT jacks. Link your FX pedal's inputs to the SEND output using a TRS audio cable, and connect the FX pedal's output to the RTRN return socket with another TRS audio cable. Fine-tune the blend of dry and wet signals with the central DRY WET knob. The level gain of the dry and the wet signal can be adjusted independently via trimmers on the back of the module. Rotate SEND to the right to increase the audio level sent to the pedal's input. The attenuator beneath the SEND CV jack controls the maximum send signal level, so remember to turn it to the right to activate the SEND jack. Increase the RETURN knob to control the effect signal's level returning from the FX pedal. Be cautious as the send signal can potentially overload the FX pedal's input, so adjust the send amount with care. Both the SEND and RETURN controls provide precise control over the signals sent to and from the effects unit for clean or slightly overdriven signals. The ST Modular logo LEDs indicate whether a signal is being sent from or returned to the module. Turn the TONE knob to the right to emphasize high frequencies or to the left for low frequencies in the SEND signal. Keep it in the center position to have no further effect. Activate the PHASE button to align the audio return signal with the dry input signal if your effects pedal reverses its phase. You may need to make further adjustments to the send and return settings afterwards. The real fun begins when you modulate the amount of audio sent to the FX pedal. Simply introduce a CV signal into the SEND CV input and adjust its level with the attenuator. Furthermore, you can also control the pedal's EXPRESSION input using CV. Connect a TRS audio cable to the EXPR I/O, and the voltage provided by the pedal will be attenuated with the EXPR knob and send back to the pedal, allowing you to manually control the expression parameters. Alternatively, you can patch modular control voltage into the EXP CV input to control the expression parameters of your FX unit, with the EXPR knob acting as an attenuator. The LED indicates when voltage is being forwarded to the pedal. Please ensure you check your FX pedals' specifications before using PEDAL PAL STEREO. Verify whether the pedal supplies its expression voltage on the tip or ring of the EXPR TRS cable and the accepted voltage level (most commonly 3V or 5V). Adjust the corresponding jumpers on the back of the module accordingly. In the video example below, I'm using an EarthQuaker Devices Avalanche Run Delay and Reverb pedal, which provides 3V on the ring of the TRS expression cable. This pedal is particularly well-suited for PEDAL PAL STEREO, as it allows for quick selection of the expression voltage destination, such as reverb amount, delay time, and more. For convenient parameter adjustments, particularly during live performances, potentiometers are positioned on the lower side, ensuring easy access when the module is mounted in the bottom row of a tabletop case.

slopes / sequenced quad slope generator / 12 HP ⇣ SLOPES is a quad slope generator with integrated gate divider. It is a good tool to create organic and moving changes that match the rhythmic pattern of your patches. 1/3 key features Quad Slope Generator 4x AR Envelope Attenuator per CV Output 8 CV Outputs in Total Internal Gate Divider Clock Input Internal Trigger & Modulation 0V to +10V Range ​ specs & downloads width: 12 HP depth: 28 mm power: 75 mA @ +12V / 49 mA @ -12V documentation videos description / manual It can simultaneously generate 8 control voltages, which are mainly changed with the potentiometers RISE and FALL. The further you turn RISE clockwise, the longer it takes for the slope to reach its maximum voltage. The further you move the FALL slider potentiometer up, the longer it takes for the slope to subsequently reach 0V. Each slope can be triggered with a trigger or gate signal and outputs a voltage from 0 to +10V (inverted outs respectively -10V). If you need lower voltages, an attenuator is available for each slope. ​ Outputs 1 / 2 and 3 / 4 provide a mix of slopes 1 & 2 and 3 & 4, but the mix can be changed by inserting an inverted signal of one slope with the "1 INV" or "3 INV" switch and the SHAPE 1 / 2 and SHAPE 3 / 4 potentiometers, which adds an additional triangle LFO to the two signals. The rate of the LFO can be changed with the RATE knob. In addition, there are inverted outputs for slopes 1 and 3. ​ The RATE knob also changes the rate of an internal gate, which is divided by 2, 4, 8 and 16 and fed to the four slope gate inputs (from left to right). This connection is broken when you patch an external gate or trigger signal into the dedicated GATE input. One LED per slope indicates if a GATE signal is present. ​ To synchronize the slopes to external modules, you can insert a clock or trigger signal into the CLK input. This overrides the internal gate generator and feeds the gate divider to trigger the four edges according to its division. The inserted clock or trigger signal is buffered and passed to the THRU output. The RST/DIR input jack can be used to reset the gate divider or change its direction. The functionality of this socket can be selected by soldering a solder bridge on the bottom side of the board. ​ The slopes can be very short and snappy, but may also last up to 10 seconds.

mia / 2x2 channel mixer with fader / 5 HP & 28 HP ⇣ MIA is a fairly simple, but very handy 2x2 channel mixer with an optional fader output. 1/6 key features 2x2 Channel Mixer Volume Control for each Channel 2 Channel Fader Fader Volume Wrong polarity protection Skiff friendly ​ specs & downloads width: 5 HP & 28 HP depth: 25 mm power: 35 mA @ +12V / 25 mA @ -12V documentation videos description / manual CH1 & CH2 have two input jacks with VOLUME control potentiometers each. The signals inserted here will be mixed and supplied at the CH1 & CH2 outputs. Simultaneously the signal will be routed to the FADER. The summed signal of channel CH1 & CH2 will be available at the FADE output. Using the Fade potentiometer you may mix the two channels to taste. The overall FADE volume may be adjusted using the FADE VOL potentiometer.If there is a cable plugged into the IN A or IN B jack, the connection of the mixer channels to the FADER is interrupted. Thus you can mix 4 sound sources and fade two additional signals at the same time. Originally this mixer was designed to mix several VCO waveforms with the ability to route each of the mixed signal (from CH1 OUT & CH2 OUT) to external modules, such as effects and filters, and then again mix the externally proccessed signals (using IN A & IN B) to one single output (FADE out) via the fade circuitry. In some cases it might even serve as a stereo mixer. This module is available in 3U and 1U! prev Up next

shikensa / cv and trigger sequencer / 12 HP ⇣ SHIKENSA is a 5-stage CV and trigger sequencer with some nifty features. 1/3 key features 5-Step Analog Sequencer Outputs 3 CV and 1 Trigger Signal 3 Different Track Lengths Internal Clock with Swing and Tempo CV External Clock, Reset and Hold ADD Input for Sequence Transposition LEVEL Control via CV for LVL OUT Wrong Polarity Protection ​ ​ specs & downloads width: 12 HP depth: 28 mm power: 55 mA @ +12V / 41 mA @ -12V documentation videos description / manual Shikensa offers the flexibility of an internal clock set via the tempo potentiometer or synchronization to an external clock. Its internal clock enables swing effects through the CLK CV attenuator, allowing tempo adjustment using external CV signals at the CLK CV input. Additionally, CV control permits sequence reset or hold actions. It is possible to change the length of the sequence from a maximum of 5 steps to 4 or 3 steps using a toggle switch. There are five sliding potentiometers that allow fine changes in CV values per step. There is a trimmer on the back of the PCB to adjust the maximum voltage from +5V to +10V. ​ SHIKENSA has a total of four outputs. OUT is the standard CV output that you would connect to a 1V/OCT input of an oscillator. If you apply a control voltage to the ADD input, you can transpose the output of OUT. IN/CK outputs either an inverted signal of OUT or the internal clock signal (this can be changed by swapping two resistors). LVL OUT carries the same signal as OUT, but its level can be changed via CV. An attenuator allows control over the amount of change. When nothing is connected to the LVL CV input and the attenuator is turned up, an internal pitch envelope is added to LVL OUT, which is great for creating percussive sound sequences. These three outputs can be used simultaneously to change not only the pitch of an oscillator, but also other parameters such as waveshapers, filters or effects according to the sequence. TRIG provides a trigger signal that can be activated or deactivated per step. Five latching push-buttons on the bottom allow you to create rhythmic patterns. An LED indicates whether a trigger signal is being output. SHIKENSA QUICK START GUIDE: SHIKENSA_QUICK_START .pdf Download PDF • 716KB prev Up next

sum v2 / 6-channel mixer with afl, eq, pan and two aux sends. / 28 HP ⇣ An innovative live mixer designed for the Eurorack modular synth ecosystem, featuring AFL listening capabilities. 1/3 key features 6-Channel Mixer Preview Sounds with AFL VOLUME, EQ, SEND and PAN for channels 1-5 MUTE Switches for Channel 1-5 + 20dB Gain per Channel 1 Stereo Input 2 Selectable Send/Return Ways ​ specs & downloads width: 28 HP depth: 35 mm power: 85 mA @ +12V / 65 mA @ -12V documentation videos description / manual Each of the 5 mono input channels has a LEVEL, PAN, EQ, SEND and AFL potentiometer and may be MUTED with a switch. The mono singal will be converted into a pan-able stereo signal. Additionally the GAIN can be adjusted using the little trim potentiometer. Turning the SEND pot will route the signal to a SEND jack in order to integrate external effects. The wet effect signal may be returned in stereo. You can choose between two SEND ways via switch. The send channels can be set to be active either pre or post AFL per channel via a solder bridge. ‚Pre‘ means you can still hear the send/return way when it is in AFL mode (thus the channels signal is actually not audible in the main mix), ‚post‘ means send/return will only work when the channels signal is routed to the main mix. Each SEND channel has a separate GAIN trimmer adjustable from the front. Channels 1 to 5 have an AFL/MIX potentiometer (AFL = after fade listening), which allows you to audit your sounds on the headphones before you add them to the mix. Fully counter-clockwise the channel is only routed to the headphones (AFL), turning it clockwise it will be smoothly subtracted from the headphone out and added to the main mix (Mix). Two LEDs per channel indicate the current state. The MIX TO HP knob routes the main mix output to the headphone out in order to compare the channels that are in AFL mode with the main mix. This can be deactivated with a switch to only audit channels that are currently not send to the main output. The headphone level can be adjusted with the HP VOLUME knob.The EQ will boost high frequencies and cut low frequencies when turning the pots clockwise and vise versa turning them counterclockwise. Additionally there is a stereo input to integrade other mixers, like PHOEBE, SUM or uSUM for example. This channel has no AFL, EQ or SEND. prev Up next

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
