ST Modular - SPREAD MIXER

video upload by Stefan Tretau

"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."

SUM MIX & PAN

18HP 4-Channel Mixer with VCA, CV PAN and CV SCAN

MIX & PAN completes the ST Modular SUM mixer series with a fully CV-controlled 4-channel mixer. It features

CV PAN, VCA per channel and a CV CHANNEL SCANNER. Each channel has a VOLUME SLIDER and a VOL CV input to control the internal VCA. The panning per channel can be adjusted with the PAN controls or the PAN CV inputs. LEDs indicate the channel volume and the state

of the panning.

All channels are summed and can be tapped at the main output jack. The SCAN and SPAN functions are really the most outstanding features of the module. They provide a unique

way to mix 1 to 4 channels using one or two CV signals applied to the SCAN and/or SPAN CV inputs. The scan functionality allows you to output a selection of channels by turning the SCAN knob or applying CV to the SCAN input. The range of channels that are activated is set manually or by CV using the SPAN knob. This not only narrows down the active channels from all to just one, but also reduces the effect the SCAN CV has

on the VCAs, as if you were shortening their decay time. When both SCAN and PAN are in the centre position and you turn SCAN, you activate one of the four channels at a time. If vou increase SPAN, more of the adiacent channels become audible until all channels have reached maximum volume (from mid to cw position). If vou decrease SPAN again, onlv one scanned channel will be

audible (mid position) and it will then start to fade out shorter (turning from mid to cc position). If a CV signal is present at the SCAN CV input and you turn SCAN to the left, the activated channels are narrowed to the left. Converselv, if vou turn the knob to the right, onlv channels 3 and 4 are activated, and in

the rightmost position, only channel 4. This module is great for creating ever-changing and organic soundscapes throughout the complete stereo

field, making your composition a very varied and a persistently interesting listening experience.

NATURAL STATE

16HP Dual Enveloped Ducking Filter Natural State consists of two 24b 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. 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.

14HP Multiple Random CV Generator

RA INFLUENCER provides a general source of useful CV tools and musical unpredictability. The module is divided into five sections, each of which performs a unique function.

The TOP SECTION is the VC INTERNAL CLOCK and TRIANGLE LFO. The rate of the clock and LFO can be controlled by the RATE knob or CV. The clock signal is normalised to the trigger input of the FALL section. The TRIANGLE wave at the WAVE socket is also routed to the WAVE/RNDM SWITCH of the FALL section. When the switch is in the upper position and the attenuator is turned to the left, the
wave will affect the FALL length. In the lower position, the FALL CV is slowly randomised.

The SECOND SECTION is a FALL ENVELOPE GENERATOR. It can be triggered internally or externally and its fall time can be controlled by the FALL TIME knob or by CV. An inverted version of the fall output is also available.

The THIRD SECTION is the SAMPLE & HOLD section. In one mode, it can sample and store a voltage from the FALL CV socket and output it at the SP OUT socket when the gate at GATE is high (Sample & Hold). In another mode, it can pass through the incoming voltage when GATE is high. It then samples and stores the last voltage applied when GATE is low (Sample & Track). The modes are selected by the MODE switch. The STEPPED potentiometer controls the level of the incoming CV signal. Internally the CLOCK is normalised to the GATE input. The CV input can be fed b an external signal, an internal SMOOTH RANDOM CV or b internal NOISE. Please note that this section may produce noise bursts in Sample & Track mode.

The FOURTH SECTION is an AND / OR COMPARATOR that compares two mixable inputs and outputs the MAXIMUM CV and MINIMUM CV of both. It also generates a GATE at B-GATE if IN B is greater than IN A. Note that MIN LED barley flashes with low CV levels. The LAST SECTION is a DUAL SMOOTH RANDOM CV GENERATOR. It provides a constantly changing CV at SMOOTH I and SMOOTH II, slowly meandering in about 60 second cycles. The SMOOTH CV input will affect the SMOOTH outputs in unpredictable ways, sometimes not at all. Internallv there is another SMOOTH RANDOM GENERATOR which is normalised to the RNDM switch position of the FALL section, the CLOCK CV and the SOURCE switch of the SAMPLE & HOLD section. Like the others, this SMOOTH GENERATOR may or mav not be influenced bv the INFLUENCE input.

NOISE OUT allows access to the internal NOISE GENERATOR You could also use the module as an OSCILLATOR

INFLUENCER is vour CV powerhouse that offers a wide range of MODULATION SOURCES and an extended source of uncertaintv.

09:25 Kick Drum Examples (Audio only)

TROMMELMASCHINE is a three-voice digital and analog drum module that can be used to create all kinds of kick drums and drum grooves.

It features a DIGITAL DRUM VOICE (D) with PITCH and TONE control that has two modes: KICK and PERC. Press and hold the MODE switch for one second to switch between the two modes. In KICK mode (LED flashes slowly) the sliders are MOD1 = DECAY, MOD2 = TRANSIENT, MOD3 = PITCH ENV and in PERC mode (LED flashes quickly) MOD1 = COLOR, MOD2 = DECAY and MOD3 = FM AMT. PITCH and MOD can be changed manually or via CV with dedicated attenuators. If nothing is connected to the CV inputs, the MOD CV attenuators change the response curve of the MOD sliders. Turn them to the right to get a linear response and to the left to get a logarithmic response. This facilitates precise adjustment of the slider positions.

The ANALOG DRUM (A) voice has DECAY, DRIVE and PEN (pitch envelope) sliders, plus PITCH and LENGTH (pitch envelope length) potentiometers. These can also be controlled via CV. The PITCH CV input tracks 1V/OCT and can be used to play notes.

The third voice is a NOISE GENERATOR (N) with COLOR control and DECAY slider. The decay of the noise can also be controlled via CV.

All voices have individual trigger inputs (D. TRIG is normalized to the other trigger inputs) and individual outputs and are also summed using an internal mixer at the MAIN output. The volume of each channel can be changed with the volume pots. Loudness LEDs indicate
when a voice is close to clipping.

ST Modular - ALSTADEN (Waveshaping Oscillator)

video upload by Stefan Tretau

"ALSTADEN is your source for harsh and harmonically rich sounds. It is a newly developed waveshaping tone generator and resembles the secondary oscillator of the semi-modular synthesizer „EUPHORIA“. The waves are formed by a combination of diode clipping and folding of the waveform by adding mirror images of the upper and lower parts of the waveform. This creates more high harmonics and interesting timbral variations. It also features an equalizer, which is quite unusual for oscillators, but offers more sonic possibilities."
