Modulation & Random envoltura / dual analog envelope / 14 HP ⇣ Experience the classic charm of analog envelopes based on the Roland System 100M 140 Dual ADSR module, made snappier with intuitive visual controls. Furthermore, thanks to its built-in VCA, manual level controls, potent cyclical gate generator, and user-friendly trigger buttons, ENVOLTURA elevates your sound-sculpting prowess to new heights. And when you double it up, prepare for twice the thrill! 1/3 key features Based on System 100M 140 Module Dual ADSR CV Level Control Inverted Output Retrigger Input Push Inputs Short and Fast Switch Manual Trigger Buttons Cycle Functionality Skiff friendly Wrong polarity protection specs & downloads width: 14 HP depth: 30 mm power: 89 mA @ +12V / 56 mA @ -12V documentation videos description / manual ENVOLTURA boasts a highly responsive analog envelope with controls for ATTACK, DECAY, SUSTAIN, and RELEASE. When a gate signal is applied to the GATE input, the envelope is triggered, and a corresponding CV signal is produced at the OUT, with an inverted version available at the INV output. Furthermore, an end-of-cycle GATE signal can be accessed from the EOC socket, which outputs a gate signal when the sustain phase of the envelope ends. The signal remains high until the start of the next attack phase. The gate is indicated by an LED. You have also the flexibility to retrigger the DECAY phase of the envelope by applying a trigger signal to the RTRG input. IN addition to manual level adjustment via the slider level potentiometer, you can modulate the envelope's level using an internal VCA by patching a CV signal to the VEL input socket. An exclusive attenuator enables precise control over the level modulation. For dynamic modulation, simply patch any CV source to the PUSH inputs and manipulate both the envelope's length and level. Fine-tune the overall length range with the SLOW/FAST switches, and if desired, activate the CYC switch to let the envelopes cycle within specific ranges. Please note that cycling may stop for very fast cycles and that the envelope doesn´t restart from 0 volts. Finally, you can also trigger each envelope manually. Please note that both ADSRs are normalised to each other, so that pressing a button always triggers both envelopes, unless a patch cable is connected to the gate input of the other.

Modulation & Random lfor / digital lfo and stepped random generator / 4 HP ⇣ Combining a digital Low Frequency Oscillator with a Stepped Random Generator, this module offers three distinct voltage outputs in the form of Pulse, Triangle, and Random waveforms. The LFO functions as both a voltage and trigger source, while the Stepped Random feature can be seamlessly looped for continuous operation. LFOR_BACK.jpg 1/3 key features LFO with 3 Waveforms Triangle, Pulse and Stepped Random LFO Rate potentiometer Voltage Control over Rate LFO Reset Stepped Random lockable to 16 or 8 steps Random Voltages normalized to LFO Rate Pulse can act as Rythm Generator Wrong polarity protection Skiff friendly specs & downloads width: 4 HP depth: 28 mm power: 25 mA @ +12V / 20 mA @ -12V documentation videos description / manual The LFO provides three voltages in shape of Pulse, Triangle and Random. It can be used as a voltage and trigger source. The frequency of the LFO can be changed using the Rate potentiometer on top. The LED is indicating the current speed. The Rate of the LFO may be voltage controlled using the Rate CV jack. The small potentiometer acts as an attenuator. Additionally the LFO cycle can be reset via a trigger signal at the Reset jack. The Triangle output provides a standard triangle waveform. Random supplies a randomly stepped voltage at LFO rate. This random voltage is normalized to the LFO CV in creating some interesting random voltages on the other outputs. This connection can be interrupted by inserting a patch cable to Rate CV. Using the Random Lock Switch it is possible to lock the random steps to identical patterns of 16 (mid position) or 8 (down position) steps. If the switch is positioned upwards it is completely random. Patching a voltage to RNDM CV will give you CV control of the Random Lock (switch must be in mid position). Any voltage above 3 volts will produce random steps, any voltage below 4 volts will lock the random out to a pattern of 8 steps. Pulse out is not a typical pulse wave you would expect from an LFO. It is rather a rythmical trigger producing one long pulse at the start of the cycle and a short pulse at the end. This way and by the normalized random voltage (if the CV attenuator is turned clockwise), you will have a wide range of random or locked pulses to trigger VCAs or sequencers. A simple AVR-programmer is neccessary to complete the build. Nevertheless it is a very easy build with only 37 parts in total. prev Up next

Effects gritzner / pt2399 delay with two switchable inputs and internal lfo / 8 HP ⇣ GRITZNER Delay is a special kind of module that is able to make all sorts of weird delay sounds, from chorus like effects to total destruction of the original signal. There are no boundaries for your crazyness here. Though the two switchable inputs and the LFO reset always make its output fit into a rythmical pattern of your patch. 1/3 key features PT2399 Delay Two Switchable Inputs, one High-Pass-Filtered Internal LFO for Input Switching Internal LFO for Delay Time Changes LFO with Attenuator and Reset Delay Time CV Input Skiff friendly Wrong polarity protection specs & downloads width: 8 HP depth: 28 mm power: 50 mA @ +12V / 30 mA @ -12V documentation videos description / manual GRITZNER is a short delay with two individual inputs that may be activated alternativley either by hand or with a gate signal. IN A is a standard audio input whereas IN B is a high pass filtered input. Frequencies below 320hz will be filtered out which is quite handy for some delay settings. If the MAN/LFO switch is on the left you can switch between both inputs manually using the A/B MAN switch. If the MAN/LFO switch is in the right position an internal square wave LFO automatically switches between both inputs according to the LFO range set with the help of the LFO potentiometer. Alternatively you may patch an external gate signal (from a sequencer for example) into GATE A/B in order to switch between inputs. The Delay itself is a classic PT2399 delay with its very special touch and a delay time ranging from 30-190mS. It has manual controls for the Delay Rate (going beyond the ICs operation range), Feedback and Wet. The delay rate can be voltage controlled with an external signal or with the help of an internal LFO. You can choose between a triangle and a square wave LFO and you may attenuate its signal with the LFO ATT attenuator. On top the LFO is resettable via the LFO RST input in order to get delay changes in a rythmical manner. The LFO rate can be adjusted with the LFO potentiometer. prev Up next

Modulation & Random yace / cv decay envelope / 6 HP ⇣ YACE is a fully featured decay envelope with voltage controlled decay length. It offers the best you can expect from a simple decay module and is a great companion for controlling other VCAs, filters or sound-changing oscillator controls. 1/3 key features Decay Envelope CV Control CV Input Attenuator Level Control Response Knob and Range Switch Cycle Function Gate Mode specs & downloads width: 6 HP depth: 28 mm power: 81 mA @ +12V / 36 mA @ -12V documentation videos description / manual A trigger or gate signal at the GATE socket (INP in the picture) starts the decay envelope and a corresponding CV is output at the OUT socket. An inverted version is available at the INV socket. With the DECAY slider you can change the decay time manually or by CV. With a CV attenuator you can control the level of the length change by CV. The DEC LVL potentiometer controls the level of the decay and is great for controlling filters. A jumper on the rear panel lets you choose whether the DEC LVL potentiometer affects only the regular decay output or also the inverted output. With the RESPONSE control you can change the response curve from very snappy to rather long and soft. The RANGE switch offers three decay length ranges, from fast decay for drums to very long decay curves for slowly evolving sounds. The INP switch changes the input mode from trigger to pulse. Pulse mode adds a sustain stage to the envelope that holds the envelope as long as the incoming pulse is high. The CYC switch activates a cyclic mode where the decay restarts when it reaches its end. In addition, an EOC (End Of Cycle) pulse is output at the EOC socket. With the INFLUENCE input (marked by a curved arrow pointing upwards) you can further change the decay level. Connect an LFO or triggers here to create attacked and more organic decay envelopes. It only responds to voltages above 5V. prev Up next

Filter & EQ hans / compact stereo diode-ladder filter and lfo / 6 HP ⇣ HANS is a compact 4-pole low-pass stereo diode-ladder filter with an internal LFO. Inspired by the famous diode ladder filters found in EMS and Roland TB-303 devices, this filter delivers a distinct and unique sonic character. The module also features an internal LFO for dynamic movement of the cutoff frequency. 1/2 key features Diode-Ladder Filter 4-Pole Low-Pass Design Stereo Inputs and Outputs Cutoff CV Control with Attenuator Internal Triangle LFO with Level Control LFO Output Only 6 HP wide Skiff friendly Wrong polarity protection specs & downloads width: 6 HP depth: 30 mm power: 35 mA @ +12V / 29 mA @ -12V documentation videos description / manual Designed for stereo signals, HANS comes equipped with stereo inputs (IN L and R) and stereo outputs (OUT L and R). However, if you want to use a mono signal, connect it to the IN L socket, which is internally normalised to the IN R input. Manual control of the filter cutoff frequency is achieved with the FREQ potentiometer. Additionally, the cutoff can be modulated using the internal LFO and/or external control voltage (CV). Adjust the LEVEL knob to introduce a triangle LFO to the cutoff frequency, cycling from +0V to a maximum of +10V. The RATE knob, indicated by an LED indicator, allows you to set the LFO's speed. It is designed for long cycles and enables very slow movements lasting more than 10 minutes, but does not achieve audio rates. To disengage LFO control, simply reduce the LEVEL knob. Simultaneously, external CV can be patched to the CV input, with the CV attenuator enabling external control of the filter's cutoff frequency. An LED indicates the current voltage level of the external CV. Improve the characteristics of the filter by using the RES potentiometer to apply positive feedback that emphasises higher frequencies. The signal may be distorted at very high resonance settings. Self-resonance is possible, but only at very high frequencies. For further external processing, the internal LFO's triangle waveform is accessible at the LFO output. This feature adds flexibility to your modular setup, enabling creative possibilities beyond the module's primary functions.

Oscillator boba fat / dual analog drum generator / 14 HP ⇣ At its core, Boba Fat features two oscillators that empower producers to easily craft both earth-shaking sub-basses and delicate, enveloping kicks. BOBA_BACK_NEW.jpg 1/3 key features Analog Drum Generator Designed for Kick- and Bassdrums Two Voices: Soft Mallet and Hard Mallet Each Mallet may be triggered independently Internal LFO with Sync Volume and Boost per Voice Groove CV Input „Vari“ for Hard Mallet Mod CV Input for Soft Mallet specs & downloads width: 14 HP depth: 28 mm power: 95 mA @ +12V / 65 mA @ -12V documentation videos description / manual BOBA FAT is a dual voice bass- and kick-drum generator. The first voice "soft mallet" generates smooth and warm sounding bass and sub-bass sounds, whereas the second voice "hard mallet" is rather considered to create kick or tom sounds. The eight potentiometers on the left control the soft mallet generator. PITCH controls the frequency, LEVEL the volume and BOOST adds low frequencies turning it clockwise and reduces them turning it counter-clockwise. MOD RATE and MOD ATT control an internal LFO and its attenuation. The LFO will affect the frequency of the soft mallet voice only. Additionally the LFO can by synced to the incoming gate or trigger. TRIG SLEW acts as some kind attack control and reduces transients making it very easy to create very smooth sub-bass drums. DECAY and RELEASE control the duration of the sounds being amplified by an internal VCA. PRESENCE changes the prominence of the sound. You can adjust the response by setting a jumper on the back of the module to either FAST or SLOW, optimizing the soft mallet circuitry for sharper, plucky tones or deeper, sustained bass sounds. The three potentiometers on the very right affect the hard mallet generator. PITCH, LEVEL and BOOST have the same function as for the soft mallet part. PITCH will have a greater effect from 12 to 5 o´clock. Changes from 7 to 12 o´clock are rather subtle, but are set on purpose to add fine nuances with LEVEL and BOOST there. OUT VOL changes the overall loudness of both drums. GATE accepts any gate or trigger signal to activate the generators. A signal at only at GATE will trigger both mallets. If a additional trigger is inserted to GATE S, GATE only triggers soft mallet and GATE S triggers hard mallet separately. This way you can have individual drum tracks for both mallets creating very interesting rhythms. A CV signal at MOD CV will override the internal LFO and CV control soft mallet pitch. It doesn‘t exactly track 1V/oct, but you will be able to play some melodies. A trigger, gate or clock signal at MOD RST lets you reset the internal LFO with an external signal. Any CV signal at VARI will slightly alternate the volume or generate additional triggers for the hard mallet circuit (depending on the incoming voltage). This gives you endless ways of creating fine grooves and interesting rhythms. The circuit was designed to easily go into distortion/clipping to encounter the limits. You may be careful using LEVEL and BOOST controls. Boba Fat definitely needs some fine adjustments in order to find the sweet spots. If you feed the GATE input with a trigger at audio rate you can also use BOBA FAT as a weird sound generator or drone machine. prev Up next

Mixer & VCA spm / 3-channel spread mono mixer / 4 HP ⇣ SPM becomes particularly valuable as it enables the dispersion of two mono signals throughout the stereo field within an audio mix. This capability proves instrumental in tidying up the overall mix, resulting in a more expansive and enjoyable auditory experience for listeners. 1/3 key features Analog Mixer 3 Mono Channels Pan CH 1&2 with one Knob Skiff friendly Wrong polarity protection specs & downloads width: 4 HP depth: 30 mm power: 19 mA @ +12V / 11 mA @ -12V documentation videos description / manual SPM is a 3-Channel Mono Mixer with three volume potentiometers. The gain per channel can be adjusted with trimmers on the board, making this mixer suitable for line and Eurorack levels. In addition, you can pan channel 1 and 2 with the SPREAD potentiometer and thus spread both channels in the stereo field to the left and right in opposite directions. In the centre position, all channels are panned to the centre. If you turn the potentiometer to the left, channel 1 is panned to the left and channel 2 to the right and vice versa. This is very useful to quickly clean up a mix and widen the sound spectrum in the stereo field. prev Up next
