Four new modules from bubblesound:
The HEXa(s)r envelope generator,
HEXvca (6 VCA module),
Booster Stage amplifier,
and Reducer de-amplifier.
Details follow for each. Bubblesound modules are available at Control, Perfect Circuit Audio, Signal Sounds, and other dealers listed on their website.
HEXa(s)r
The HEXa(s)r is a 9HP module with 6 independent AR/ASR envelope generators and 3 mixer sections for a total of 9 outputs, giving users a huge amount of modulation options with a very small footprint making this the most versatile and flexible envelope generator in the eurorack world. Plus it’s skiff friendly and light on power consumption.
Each envelope generator has a gate input and can either be an Attack/Release or Attack/Sustain/Release. In AR mode the incoming gate is turned into a trigger giving you a simple Attack and Release, perfect for drum synthesis and simple modulation or control over VCAs. In ASR mode the length of the Sustain is controlled by the length of the gate. This makes using an LFO’s modulated Pulse Width output or a sequencer with variable gate length perfect for creating envelopes with changing sustain times, breathing life and variation to whatever the HEXa(s)r is modulating. The LEDs are tied to the output to give users visual feedback on each EG.
The HEXa(s)r can use gates (0-8/10V) or a +-5V to trigger the envelopes. It can accept trigger inputs as well, but when using a trigger in ASR mode there will be almost no sustain as the duration of triggers is very short, usually around 5-10 milliseconds.
The Gates in of the HEXa(s)r are normalized so one gate into EG1 will trigger all 6 envelopes. Each envelope generator can then be set to either AR or ASR mode. OIr you can use the output of one EG to trigger another EG. This can be used to make a type of gate delay for individual outputs or complex rhythm or modulation effects from the Mix output section.
The Mixer section has 3 parts, EG 1-3, 4-6 and All. By using multiple gates and triggering some EGs from other EGs the mix out section can create some unexpected modulation options or very controlled rhythmic outputs. It all depends on what you put into it.
There is a header on the back and included 6 pin ribbon cable that will allow the HEXa(s)r to connect with the upcoming HEXvca without using patch cables.
Details:
6 independent EGs. Attack and Release times are around 4 seconds each
Normalized Gates
30MM deep, single PCB skiff friendly design
Output Level: 0-10V
Interconnectable via supplied ribbon cable to the HEXvca
Power Consumption: 50mA positive, 40mA negative
9HP
HEXvca
The HEXvca is 6 independent VCAs with 3 mix outputs. Each VCA is switchable between a linear and exponential CV response. The CV inputs are normalized using jumpers on the back, so 1 or 2 gates or EGs can affect several VCAs at the same time.
With headers on the back the HEXvca can be triggered by the HEXar using a ribbon cable eliminating the need for patch cords. There is also a 6 pin header for the audio inputs for future expansion without patch cables.
The MIX section allows the HEXvca to be a voltage controlled Mixer, channels 1-3, 4-6 and 1-6 have dedicated outputs. The VCAs are DC so the VCAs can be used for audio or CV.
The HEXvca uses SSM2164 VVCA chips that provide plenty of headroom, very low distortion/noise and use very little power. The HEXvca is 7HP and around 30MM deep. You can never have enough VCAs but with the HEXvca it’s easier to have as many as you need.
Width: 7HP
Depth 30MM
Power Consumption: +50mA -45mA
Booster Stage
The Booster Module is a 2HP amplifier to bring desktop synths, drum machines and effects into a eurorack system. It has 4 separate amplifiers.
The inputs are normalized so 1 input can give up to 4 outputs and when the output of one stage is plugged into the input of another stage it turns into a brutal opamp overdrive circuit.
The Booster Stage is skiff friendly and has very low power consumption.
Width: 2HP
Depth: 30MM
Power Consumption:
+20mA -15mA
Reducer
The Reducer Module is a 2HP deamplifier to bring eurorack synths, drums and effects down to line level so they can easily be used with stomp boxes, effects processors and samplers.
It has 4 separate deamplifiers. The inputs are normalized so 1 input can give up to 4 outputs .
The Reducer is skiff friendly and has very low power consumption.
Width: 2HP
Depth: 30MM
Power Consumption:
+20mA -15mA
