Building the Super Sixteen Eurorack Sequencer

You cab download KiCad EDA 5.0 for free here: http://kicad-pcb.org.
For a detailed look at how to multiplex a grid of LEDs, check out this tutorial (a shift register is used instead of an i/o expander).

Playlist:
1. Designing a Eurorack Sequencer - Pt. 1: Digital to Analog

In this new series I'll be designing, prototyping and building a sequencer module for my eurorack sythesizer using the Arduino platform. In this episode, we connect the arduino to our 12v power supply and add a digital-to-analog converter output so our sequencer can output proper 0-8v CV signals.

2. Designing a Eurorack Sequencer - Part 2: Seven Segment Displays

Continuing to design and prototype the Super Sixteen sequencer module for my eurorack sythesizer using the Arduino platform. In this episode, we wire up a seven segment display to show some visual feedback using another serial chip, the I/O expander. Then we take a crack at making our sequencer play a scale!

3. Designing a Eurorack Sequencer - Part 3: Enter the Matrix

Continuing with the Super Sixteen, we build the sequencer's namesake sixteen-button grid, explore matrix wiring and multiplexing in combination, and construct our first working prototype that actually plays a sequence!

4. Designing Eurorack Sequencer Part 4: Making a PCB with KiCad 5.0

In this episode we get into some proper electronics design with KiCad and develop a new layout for a printed circuit board. Then we get to do the fun part and fabricate it at home using a toner transfer and ferric chloride etching.

5. Designing a Eurorack Sequencer - Part 5: Assembly

In this episode we assemble the first PCB prototype of the Super Sixteen with our trusty soldering iron and a spool of mod wire. After a few fried chips and more than a few repairs, it's time to wire it up to our synth and try out some actual sequencing!

6. Designing a Eurorack Sequencer - Part 6: Front Panel and External Sync

Or, "How to Make a Eurorack Front Panel: The Cheap Way"
In this episode we upgrade our module with a faceplate, and add some advanced features like external sync, pitch calibration, and glide/portamento.

7. Designing a Eurorack Sequencer part 7 - New PCBs, Motion Recording, Beat Repeat

In this episode, we assemble, inspect, debug, and reprogram our new dual-PCB stackup for the Super Sixteen eurorack CV sequencer. Not everything goes according to plan!

8. Designing A Eurorack Sequencer Part 8: New panel, Patch memory, Performance effects

In this installment we fabricate a new front panel for the Super Sixteen using the toner transfer process, and then take a spin with some of the new advanced features it sports, like patch memory, scale selection, swing timing, and a gang of performance rhythm effects.

Korg Monotron CV Input Mod (Eurorack Control Voltage hack)

Published on Sep 21, 2019 Extralife

"Hello friends! I'm back in California and back in action. First off the hop is a travel kit project to convert CV (control voltage) signals to Monotron-compatible pitch/gate signals. If you have a Monotron (the cheapest analog synth on then market) you can use it to add a complete synth voice to your eurorack system!

The schematics and PCB layout for this project are up on my github page:
https://github.com/matthewcieplak/mon...

This work is partially based on DINSync's 2010 monotron CV mod:

GSE 101E Output Expander for 101-VCO Quick Demo (Roland SH-101)

Published on Sep 24, 2019 gstormelectro

"Audio and Video by G-Storm Electro c. 2019

Quick intro to my 101E Output Expander for my 101-VCO.
101E adds buffered, individual wave outputs from the 101-VCO.
I will show how to interconnect them.
And just a few things you can do with the expansion.

Links for more information...
101E https://www.modulargrid.net/e/g-storm...
101-VCO https://www.modulargrid.net/e/g-storm...
Buy http://reverb.com/shop/gstormelectro

Recorded direct to Tascam DR-05.
No additional effects or processing."

"Output Expander for GSE 101-VCO

Companion module for the GSE 101-VCO.
Adds 5 buffered, individual waveform outputs.

What you can do with the 101E:
- Send each waveform to a mixer and give them different panning in a stereo configuration
- Use the Noise for percussion apart from what the synth waves are doing.
- Send two waves to a dual VCA, and use modulation to crossfade them.
- Send the waves to different filters, each having their own sequence.
- Toggle different waves using a 1x4 sequential switch, or the GSE Infusor-X, for wavetable-like effects.
- Send two waves to a sidechain processor like the Worng LRMSMSLR.
- and much more!

This module requires the 101-VCO and Eurorack +/-12V power for operation.

Gotharman Releases Little deFormer 3 and Tiny LD Updates

Available at Gotharman's Musical Instruments, the update adds new resonator oscillators, smooth oscillators and microtuning. You can find demos here: New Oscillators, Resonators, Microtuning. Also see Gotharman's LD3: Color Of The Sky. Currently you can find all the demos and more on the first page for the Gotharman label. Posting the individual links for future reference as new Gotharman posts are sure to go up and make them more difficult to find in the archives.

Update 11.62 Details:

-New oscillator types: Smooth oscillators and Resonator oscillators.

-The 2 new oscillator types can be microtuned per key in an octave.

-More oscillator modulation destinations: Extra pitch modulation, Reso, Sample length and Portamento.

-Monophonic trigger system improved.

-Output Effects gain can now be adjusted.

Bug fixes:

-If linear envelopes were used, with different settings for each part, sometimes the settings of each part would interfere with each other, i.e. long attacks would appear on parts, that it was not supposed to. This has now been fixed.

Korg Volca Nubass Compact Vacuum Tube Bass Synth

Published on Sep 24, 2019 Perfect Circuit

"The Korg Volca Nubass is a compact bass synth with vacuum tube based oscillators and a transistor ladder based filter. It also features a sequencer that is great for acid basslines.

The tubes have a nice gritty sound and the filter cutoff is the largest knob on the synth for easy tweaking. Since this is a Volca it is battery powered and easy to sync with all of the other Volcas. We added drums with the Elektron Digitakt, but used the internal sequencer on the Volca Nubass.

YAMAHA EX-1 Synthesizer/Organ

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

Note the EX-1 is not the pre-cursor to the GX-1. That would be the "EX-42 (1970–1977, stage model, design origin of GX-1)" according to the list of Yamaha products on Wikipedia.

"This Yamaha EX-1 organ/synthesizer is one of the rarest synthesizers in existence, as it is rumored that less than a dozen or so were ever built.

The EX-1 is easily programmed for three overall patches using a slide-out front panel,and has polyphonic glide and, on the solo keyboard, a unique side-to-side movement for modulation.

The EX-1 features two fully polyphonic keyboards (with organ tabs and polyphonic analog synthesizer sounds) which can be slaved together, a top keyboard monophonic analog synthesizer which can be slaved to the upper organ manual, and a monophonic analog synthesizer bass played from the included pedals, or slaved to the lower keyboard.

Also included is an analog drum machine, auto chord accompaniment section, and arpeggiator.

This YAMAHA EX-1 unit is in great condition.

Manufacturing date maybe 1977-1978.

All the knobs, sliders, keys and pedals work perfectly.

Also included are two TX-III tone cabinets with 14x speakers (each), bass pedals and a original matching bench.

The features of this synthesizer are much too extensive to list here.

There are a few videos on YouTube that fully detail all of the capabilities of the EX-1 Just search for "Yamaha EX-1" and prepare to be amazed.

When released in 1977, the EX-1 had a $35,000 price tag.

That's $148,000 today when adjusted for inflation.

Don't miss your chance to get it for much less!"
