AJH Synth Tap Tempo VC-LFO Eurorack Module (Silver)

AJH Synths’ new module is a tap tempo voltage-controlled VCO that is part of the Mini Mod lineup. It features sixteen different waveforms available ranging from classic up to more wild. It contains also S&H-like random stepped voltages and a unique random sloped voltage.

They are distributed in two banks selectable via an 8-way rotary switch and bank selector switch. Amazing here that you can not only manually switch the waveforms but also with control voltage. Then, you can tweak them using four different parameters. A CV-controllable multiply function allows you to double, treble, quadruple, or half the LFO rate. So you can vary the modulation frequency but still keep it relative to the tempo of the track. That’s very handy.

Next to this is a frequency knob with CV control that covers a wide range from 0,05Hz (one cycle every 20 seconds) to 50Hz. You can also patch another modulator in the frequency input and create exponential frequency modulation.

There is also a unique waveform twist function that gives you PWM-style duty cycle variation. This can be applied to 15 of the 16 waveforms. And you get a level knob to control the modulation amount level.

Connection side, the Mini Mod Tap Tempo VC-LFO has CV inputs for all the features as well as clock in/out and simultaneously bipolar and unipolar outputs. It also has a built-in VCA allowing easy control of the modulation level of both outputs.
