We have a new eurorack modular manufacturer featured on the site. I'm not sure how long Liivatera has been around, but this is the first post to feature them. I found out about them in a press release for the next SDIY UK meet that will go up next. They will be introducing two new modules at the event. You can find their current lineup here. Their Mixer/Attenuverter/Offset and Sample/Track & Hold modules are featured in this post for the archives.
Be sure to check out the rest of their site. They offer IC Design Services, Product Design, Small Volume Assembly, Prototyping Aids and various Utilities.
"Mixer/Attenuverter/Offset
Five Attenuverters.
Each input amplifier can be individually scaled between +1 and -1,
Five Offset Voltages.
With no input signal these can be used as static control voltages, or can offset the input signal. Turn an LFO into an EG instantly. Bi-colour LED's indicate the output voltage, so it's easy to see if a signal crossing zero-volts.
Versatile Mixing.
If a jack isn't plugged into an output socket, the output is automatically summed into the output of the channel below.
Five-Channel Mixer.
The five outputs are summed to produce a sixth output that has a master level control."
"Sample/Track & Hold.
Sample Mode: The Out signal is updated to with the Input signal every time the Clock crosses the Trigger level in a positive direction.
Track Mode: When the clock input signal is less than the trigger level, the In signal passes straight-through to the Out socket. When the clock signal is greater than the trigger level, the Out signal is 'frozen' and no longer track the In signal.
When there no jack in the Clock socket, the LFO is routed internally to the sample & hold.
The Trigger Level range is -5 to +5 Volts, to accommodate both bipolar and unipolar trigger signals. When a ramp signal is used as the clock, adjusting this level changes the timing of the internal trigger signal.
Low Frequency Oscillator.
The LFO frequency can be set manually with the Frequency control, and externally using the two CV inputs. These are both temperature compensated and have a nominal 1volt/Octave characteristic.
Three waveforms can be selected, and the output level set by the Amplitude control. A front-panel LED indicates signal polarity and level."
