Waveform: 6-way rotary switch to choose the waveform: square, random, sweep, triangle, sin or 'ramp up' waveform.Symmetry: changes the waveform, by modifying its duty cycle.Depth: set the tremolo's deepness, from very subtle tremolo to huge choppy tremolo!.Next, there are 6 potentiometers (many options!). This is nice to add some choppy stuffs while you play! The little switch in the middle of the two LED (bypass LED, and tempo LED) allows you to switch the pedal temporarily. Indeed, 3PDT footswitches are the main reason for guitar pedal failure. The Tap Tempo VC-LFO is truly a modulation powerhouse.That is a lot of knobs! You can already notice that t here are two footswitches: tap tempo (right side), and the true bypass footswitch that is a clickless relay bypass system! I used the relay bypass system that I conceived, which is completely silent, and more reliable than classic 3PDT true bypass. Bipolar and unipolar outputs are available simultaneously and the built in VCA allows easy control of the modulation level of both outputs. Voltage control is implemented for all functions, including waveform selection and exponential control of the modulation frequency. Random stepped voltage and random sloped voltage outputs are also available, and are clocked at the LFO rate. The modulation range is from an impressive 0.05 Hz (one cycle every 20 seconds) to 50 Hz. The MULTIPLE function can double, triple, quadruple or halve the LFO rate, so that the modulation frequency can be varied but still kept relative to the speed of the track, also to create a ratcheting effect when used with a sequencer. The unique waveform twist function allows PWM-like duty cycle variation to be applied to the waveform. Sixteen different waveforms are available in two banks and the eight-way rotary switch and bank switch allow easy waveform selection.

The Tap Tempo VC-LFO is a 12HP wide complex LFO with a huge range of useful features including Tap Tempo and internal/external clock controls. The GATE output can be used to drive an external ADSR or complex envelope generator, and users are able to select one shot or retrigger modes and even external fast to continuous loop modes. CV control of all functions is possible, and we can automate how envelopes vary over time to create a “bouncing ball” and many other effects from this single module instead of four or five modules and complex patching which are normally required. With the slope control in the center position all envelopes will be generated at the maximum level. Slope control allows bursts to start silently and build up to a maximum level, or they can start at a maximum level and then gradually decrease in amplitude as the burst sequence progresses.

Alternatively, an external clock can be used to trigger envelope duplication and a mixture of internal and external clock control can be used to generate complex polyrhythms. The time between each envelope repeat can be changed with the rate control, which acts like an LFO and can be changed in real time as a burst sequence is progressing.

There is a choice of eight different envelope shapes, and the attack and decay times of these can vary with the P-WIDTH control. The Multi Burst Envelope is a 12HP wide module that can generate between one and 40 repeating envelopes that can either remain stationary or change over time. Now they have turned their hand to create some unique modulation sources with their new Multi Burst Envelope Module And this Tap Tempo VC-LFOAvailable with Vintage Black or Silver faceplate. UK based synth producer ajh synth Perhaps best known as the company that brought uncompromisingly authentic vintage synth sounds and circuitry to Eurorack, and their modules have found their way into the hands of many A-list musicians and musicians.
