And, as if by musical magic, the collaborative Clarke company concept was born. And with it the first of those creative and utilitarian modules for the ever-present Eurorack small-format modular system that is increasingly popularised (and heavily populated) by an ever-growing band of merry ‘boutique’ manufacturers now numbering hundreds worldwide… welcome into the world Clarke’s clever Auto Tune system! So, let’s learn a little more about what it is, what it does, and how, exactly, it does it…
Available as a kit or completed module this sucker is deep with features.check it out at Hexinverter.net
The ACXsynth MIDI2CV Eurorack module is an 8HP, 4 channel CV/Gate interface with a robust feature set you can build yourself!
The original circuit and firmware were designed by the talented Alain Coupel of ACXsynth. His design is used here with permission. Dmitry, a forum member, took it upon himself to update the firmware with a slew of new and exciting features!
- 12bit DACs with high quality Intersil opamps for great CV accuracy
- Monophonic mode offers full control of one voice (mod, pitch wheel, etc.) as well as sequencer control (start/stop, reset, sync)
- Split and duophonic modes accessible through advanced features
- Sync output emits MIDI clock pulses for driving sequencers
- MIDI channel auto-learn at startup means no configuration if only basic functionality is desired
Now that the Circuits have all been Built. we can wire them all together. This is really quite straight forward. Simply wire everything in parallel. This means that the power wiring for each module goes directly back to the source. This allows us to not have voltage drop across each component.
make sure to leave plenty of extra wire so that you can place knobs and connectors where ever you want in your enclosure.
I will return shortly to show how everything is mounted in the case and give it a nice run through!
The BeatHawk iPad app has been hotly anticipated for some time now. With powerful step sequencing, easy to use sample recording and editing, song arrangement, fx and more. BeatHawk from UVI boasts and intuitive workflow that lends it self greatly to instant hands on creation of beats while on the go or in the studio.
BeatHawk offers full support for CoreMIDI, Inter-App Audio, AudioBus, Audio Copy and WIST allowing you to create with your favorite tools in whatever way you like. Play your tracks with an external MIDI keyboard or sequence them over Wi-Fi from your computer. If you want to wrap up a track in your favorite DAW just export the stems or MIDI files, it couldn’t be simpler.
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!
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.
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!!!
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
