How to Synth DIY part 5 PT2399 Delay Dev board!

Part 5 The PT2399 DEV DELAY KIT

 

This circuit is actually very very simple to assemble and shouldn’t really take you more than a half hour tops to build.

It comprises of a board with pads for a few knobs and jacks, as well as a few extra parts so that you can play around and add modifications to the circuit. The PT2399 is a chip that is found in MANY guitar delay pedals. It is a digital chip that emulates the analog bucket brigade. As delay times get longer, the audio degrades. This can be used to great effect when you start to play with long delay times and feedback.

In this video I build the PT2399 Dev board, I do not show me building in any mods. The reason for this is I want you to feel free to experiment with the board. you won’t harm the chip its quite robust and is great fun to play with “circuit bending” it. just basically wire up a momentary switch (included with the kit) and touch the leads to any two points you find interested (by poking a piece of wire around you may find the chip behavior act interesting). For the final circuit I went with the suggested Feedblast the warp and the feedback as pictured below.

instructions for these mods can be found HERE http://www.synthrotek.com/kit-assembly-instructions/other/pt2399-dev-delay-assembly-instructions/

The kit only costs : $30 so… hard to beat for a funky ass delay right?

Check the video and have fun!

How to Synth DIY part 4 ANYONE can Build the 555 LFO!

Yes thats right! Anyone can build the 555 timer LFO… and to prove it, I let my 8 year old daughter do it! This was Elly’s first time soldering and she enjoyed it immensely (even with a minor mishap!) If she can jump on the Synth DIY horse, SO CAN YOU!

 

The 555 Timer Oscillator from Synthrotek will be a modulation source for our upcoming Delay Dev kit circuit. (and other circuits as we will keep this modular!)

the Idea is to use this to modulate the rate of the delay board.

For this project, we won’t be hooking up power just yet as I plan on daisy chaining the power off of another circuit first.

we also will not solder on the attenuator just yet as we will be using wire so that we can place the board more efficiently inside of the case. You can buy the 555 Timer LFO HERE—> Synthrotek Store  it’s only $15.

How to Synth DIY part 3 The Passive Ring Modulator

The Passive Ring Modulator

 

This circuit is a very basic one which is why I have chosen it to be our starting point. It is also quite inexpensive with very easy soldering so it should make a great first time soldering project!

A ring Modulator basically takes two incoming signals and combines them spitting out what results in a modulated version of the original signal. This technique was used to create the famous Dalek voices in DR. Who television series.

It can also be used to beef up synth signals, Warp Drum tones, and distort strings etc. overall just a very useful circuit to have handy.

The Passive Ring Mod doesn’t require a power source so no worries there.

Take a look at the video and Have FUN!!!

HOW to Synth DIY Series Part 2 (Kit list and soldering info)

How to synth DIY part 2

Synthrotek logo

Now that we have established some basics it is time to take a look at what we are actually going to be doing in this series. I want to start off by giving a list of the Synthrotek Kits we will need in order to complete this series. You can purchase these kits as we go along or all of them upfront (getting them upfront is not a bad idea as we will likely have some live Q&A sessions and it will be nice for you to have the kits ready).

Here are the planned kits that will be involved.

1) Passive Ring Mod Kit (think Dalek voice)

2) 4093 Chaoss Nand kit (drone oscillator)

3) 555 Timer kit (this will be used as an LFO to control delay etc)

4) Dirt Filter 9v kit (distortion and filtering)

5) PT2399 Dev Board kit  (this is a digital delay that emulates analog delay chips)

6 Vac Pack (adds CV control to any variable resistance controlled circuit)

7) Plastic Enclosure  (this will be what we place all our items into) you are not limited to use just this case, feel free to use more than one case or a larger case if you like.

Eiosis AirEQ Premium EQ VST Review

AirEQ, Beyond Analog

AirEQ was designed with a vision of achieving musical, technical and sonic excellence.

Simple, intuitive and quick to use, AirEQ is a musical equalizer plugin at its best.

The Water and Fire curves, as the Character and Strength parameters were adjusted by ear, so mixing engineers can focus on one thing – making music sound great.

AIREQ is a premium eq that allows you extensive control over your mix. Utilizing it’s unique character attribute you can custom taylor your sound to be biting or smooth and transparent.

Laid out in a very easy to use and read design AirEQ allows for hands on luscious sound sculpting.

Demo download is available on Eiosis website 

AirEQ has been designed to fasten the workflow of mixing engineers, so they can reach quickly, and intuitively, the sound they have in their mind. The musical Q/Gain adjustement, along the Strength behavior, used with the ultra-musical analyzer, is the perfect combination of listenting, intuition and analysis within the same plugin interface.

Hide the analyzer for an “ears-only mode”, right-click on band switches for advanced options, shift-click on the Q for per-band Character, rename bands to make your own presets, assign each band to Left or Right, Mid or Side, class bands by frequency order..

How to Synth DIY

 

Synthrotek logo

          Here at FluxWithIt.com there is a mind set… If you are not thinking beyond intended operation, then you are limiting yourself.  To better illustrate this philosophy as it pertains to the studio. I have decided to take you all with me on down the rabbit whole and into a land where an old guitar pedal is a synth, a simple 555 timer chip is a modulation source, a plain plastic box can become a sample manglers wet dream. Luckily with Sponsor Synthrotek I will be able to help you on your journey to Nerd heaven.

Before we take the blue pill and get to tripped out on bending and circuit melding, Lets gather our thoughts.

First we need to assess just what it is we SHOULD know before attempting any of this.

here are some bullet points of what I feel you should know… and I will help assist you in learning. Read the rest of this entry »

Animodule GATE_MOD Eurorack Modular trigger delay

Let’s face it, couldn’t we ALL use a little more length?

This Tiny (yet powerful) Module allows you to manipulate your gate length and delay your event triggers with ease and minimal impact on your HP.

Take an incoming Signal above ~1.1V (OpAmp Comparators on the Inputs make very forgiving Clock Inputs)
and shrink it down to 5MS or lengthen it up to 5 Seconds.
That Gate will appear at the Gate Out. Read the rest of this entry »
