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 https://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!

Posted on by

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!!!

Animodule GATE_MOD Eurorack Modular trigger delay

Posted on by

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. Continue reading →

Animodule V9a Eurorack CV controlled sequencer and waveshapper

Posted on by

It’s a wonderful bit of kit that takes your waveforms and turns them into sequencing steps and rhythmic patterns!

V9a

Here’s a powerful animal to add to your sequencing arsenal.

Send your CV to the CV In. As the Voltage increases the sequence steps forward. As the voltage decreases the sequence steps back.
Scale and adjust your input voltage to taste with the Onboard Attenuator and Offset.

Control the Output CV with an individual Potentiometer for each step.

When a step changes, a 10MS trigger is sent to it’s corresponding switch. If the latching switch is depressed it allows the trigger to pass to the Trigger Out.

There is a switch per step for slew (portamento/slide).
and a Potentiometer to control the Slew Amount.
There is also an input to allow gated control of when the slew turns on and off which will work in conjunction with the switches.

This module is looking for 0V to +5V. The Offset is 0V to +5V.

To allow for chaining of the V9a and rests, 0V will put you under the sequencer range and +5V will put you over the sequencer range.
When the sequence drops below step 1 or over step 9, 0V will be sent to the CV Out and No Trigger will be sent to the Trig Out.
When step 1 or 9 is activated a trigger will be sent to the Trig buss.

Max Current Draw:
+12V = 40mA
-12V = 11mA

Width: 14HP Depth: 39mm
