Takaab RLFO: Unlocking Random, Stepped and Gradual Control Voltages with Built-in LFO, Sample & Hold and Noise Circuits

The Takaab RLFO module by Siam Modular is a versatile modulation and control voltage generator that offers more than what meets the eye. It packs an array of functionalities into its compact design including a built-in LFO, sample & hold, and noise circuits, allowing it to produce random, stepped, and gradual control voltages.

Starting with the LFO, the Takaab RLFO comes with two outputs, square and triangle, for added flexibility in shaping your sound. What's even more impressive is that the LFO is internally normalized to the clock input of the sample & hold. This means that you can easily control the behavior of the LFO with a patch cable, delivering pitch-shifting frequency modulations, vibrato, or other desirable effects.

In addition to the LFO, the noise circuit is also normalized to the signal input of the sample & hold, making it simple to generate stepped voltage without external patching. The noise produced is close to white noise with some roll-off at the top and bottom of the audible frequency range. Moreover, the slew circuit on the output enables you to dial in more gradual or wobbly control voltages, enhancing the sonic range of your modules.

You can sample any external signal, be it audio or CV, through the SIG IN input, while external clock, gate or trigger signals in the CLK IN jack can be used to trigger the sample points of the S&H. When external signals are input into the CLK IN and/or SIG IN, the internal LFO and noise of the RLFO can still be used independently from the sample & hold.

Overall, the Takaab RLFO module by Siam Modular is a must-have for any modular synth enthusiast looking for unpredictable and original soundscapes. Its ability to produce a wide range of control voltages makes it an excellent addition to any eurorack setup that requires modulation and control voltage generators.

Example Usage

If you're new to modulation and control voltage generators, the Takaab RLFO is a great module to explore. Try patching the output to the VCA input of your synth, and vary the clock input to the S&H circuit to create random rhythms and textures. You can also experiment with patching external signals into the CLK IN and SIG IN jacks for even more creative possibilities. The slew circuit can help smooth out any drastic voltage changes, so play around with it to fine-tune your sound. Have fun exploring the endless possibilities of the Takaab RLFO module!

An intermediate-level patch using the Takaab RLFO would be creating glitchy percussion sounds. Start by patching the clock output of the RLFO to the clock input of a sample and hold module. Then patch a noise signal into the signal input of the sample and hold, and an envelope generator into the sample input. The output of the sample and hold will be a stepped random voltage that will trigger a percussive sound source. The slew output of the RLFO can also be used to add some smoothness to the sound. Try changing the clock rate and adding modulation to the slew to further modify the percussion sound.

Further Thoughts

One great way to use the Takaab RLFO is in conjunction with a sequencer or other rhythmic source. By patching the clock output of the sequencer into the CLK IN of the RLFO, you can create interesting, randomized variations that follow the tempo and rhythm of your sequence. Meanwhile, patching the output of the RLFO (which will now be a stepped or gradual control voltage based on the sample-and-hold circuit) into a filter, oscillator or other sound generator will introduce constantly evolving sounds and textures that play off of your programmed sequence. This is a great way to add depth and complexity to your compositions, and the Takaab RLFO offers plenty of flexibility and versatility in achieving it.
