#TAPTEMPO LFO HOW TO#
Just one suggestion: make it clearer in the assembly guide how to place the diodes, and how to wire the plugs to the pots and jack. It's a very nice module with slow and fast LFO's! I'm also fond of the negative/positive waves, gives nice effects with modules that don't support it (such as Music Modular's Chord organ). The following day, it worked perfectly! Very strange. It would only give something at the bottom end of the range. And decided to follow his lead with the colors of the wires.Īnd then: it seemed to work. I searched for a picture on the site, which showed them more clearly. Then I remembered I also seem to have a different way of connecting the plugs. Just removed them (read on your blog they were only for protection, guess I'll have to be careful :D ) No change at first.
Tried removing them and re-placing in all ways, never got the expected voltages at the test points. I tested it, and it didn't work, just didn't do anything. Decided it would be best not to test that very evening, since I was already kinda tired. I assemble it on an evening, was very uncertain about the placement of diode D2 and D3. It has been quite the journey! (with a very positive ending) I bought the Simple LFO 1.4 a couple of weeks ago. Simple LFO Build documentation (PDF Version 1.5)ĭ2 and D3 are mounted vertically, and the white band is up ("Cathode Up").Please visit for updates, documentation and more informations.

#TAPTEMPO LFO SERIES#
The Simple LFO is featured in Kristian Blåsol's great video series "Modular In A Week" episode 4.1: (Please note that PCB silkscreen and solder mask color can present some slight irregularities.) The NEW Front panel is a 4HP 1.6mm thick BLACK PCB material. Resistors, capacitors, the 9mm potentiometers and Davies 1900h knobs, connectors, two SPDT switches, the IC and its socket. In the Kit option, you will find the following: The PCB is only 5 x 5cm About the options Power requirements: +12V / GND / -12V less than 20 mA You only need cutting pliers, solder tin and an iron. Can I build it?Īssembling this module is pretty easy and should take less than an hour. The output signal can be attenuated with the potentiometer Amplitude.
Powered at -12 / +12V, the maximum output amplitude swings between -6.3 / +6.3V peak-to-peak for the triangle waveform and -5V / +5V for the square waveform. Frequency Ranges RangeĬheck my Attenuater/Inverter module if you need to adapt or invert its output. You can also use its output as an audio source. Just plug a mono jack and link it to your VCO or VCA or VCF or any other VCxxxx. Frequency is adjustable with the potentiometer. The frequency range is impressive, from less than a Hertz to thousands of Hertz. The Schmitt Trigger flips over the charge/discharge cycle. The "integrator", (a constant current generator) charges and discharges a capacitor.
The circuit is a classic integrator and Schmitt Trigger duo. NEW: You can also order a black Front Panel, 4HP, in PCB material, 1.6mm thick!
