Infini - Prophet 6 - No external Effects


Published on Aug 25, 2018 100 Things I Do

"While waiting for the F1 to start last night I though I would spend some more time investigating the Prophet 6. I came up with a basic sequence then played over the top. I found the sequencer with delay plus the voice stealing from the sequence when you play over the top gives a very interesting effect. It makes the sequence sound more like an evolving arpeggio or pattern!

In this clip I have only used the Prophet 6, its inbuilt effects and sequencer. I did a very small bit of EQ to control the bass and added limiting on the output to keep all the levels sensible."

Meet OTTO - New Raspberry PI Based Multi-Engine Based Synth Inspired by the OP-1


Details via Github:

"Making electronic music is awesome! But for most of us, it requires a lot of setup, a lot of moving a mouse around on a laptop that's probably not quite equipped to handle realtime audio processing. Don't you wish you had one single device, which was xbuilt to do it all for you, easily and on the fly?

Introducing the OTTO!

The OTTO is a complete hardware and software solution, with synths, a sampler, effects, sequencers, and studio modules. The interface is modal, easy to use, simple, but most of all, it encourages experimentation. The graphics are quirky, and the workflow is minimal.

That sounds cool and all, but haven't I heard about this before?
— You

Yes, the OTTO is heavily inspired by the OP-1, in fact it started off as a direct clone, but these days we try to take a different spin on an idea that is fundamentally the same.

At this point it might be important to mention that the OTTO is not, and will never be, a commercially aimed product. It is open source by nature, in both hardware and software. If you want an OTTO, you're going to get your hands dirty, if not with the code, at least with the hardware.

Now that proper introductions are made, we would like to invite you to our discord server where we hang out and discuss all things OTTO.

The OTTO is basically going to be a Rpi3 (or other similar boards, we are looking into that), a screen, a DAC, 4 encoders and some 30+ buttons/keys. Some of us are currently building prototypes, and the formfactors and features vary greatly. Below this you see two OTTO hardware prototypes. Feature wise they are similar, but the first one is hand-wired, lasercut, and uses arduino pro micros for handling the keys/encoders. The second one is 3D printed, uses a PCB with onboard microcontroler etc.

As you can see, the OTTO can be built very differently depending on your skills, your avaliable resources and tools, and your priorities. You can also have other features than these two, for example the DSP all supports velocity sensitive keys.

You can find more info about the first prototype design on the "Otto Proto One" on this dedicated repo, and @cester-ino's over at his repo

The software

The software is written in (very) modern C++, and the goal is to be as modular and flexible as possible.

Technology
Core C++ 17 (you will need a very new compiler.)
Graphics C++ wrapper on top of NanoVG, with swappable backends, currently GLFW and EGL are available.
Audio/MIDI Designed to be swappable, though currently the only one available is jack.
DSP C++ and Faust (compiled down to C++)
It is possible to run the software on the desktop, with keybinds emulating the physical buttons and encoders.

For build instructions, check out the wiki.

Backbone

While OTTOs may differ on a lot, some things are fairly set in stone :

A Raspberry Pi (or similar) at the core, running a minimal Linux distro.
A >= 320x240 RGB screen, preferably AMOLED.
~30 hardware buttons, so nearly every feature has its own button.
4 colour coded rotary encoders (full credits to the OP-1 for that idea), as the main controls. Each screen has a maximum of 4 variables which will be coloured corresponding to their encoder.

Roland HS 60 (Juno 106) With Chorus Input Mod


Published on Aug 25, 2018 Matthew Sullivan

"This includes a short demonstration of the chorus signal input feature that has been added. The Mono-In jack, originally intended for regular speaker input, now routes any external signal through the chorus. While plugged in, this can be disabled simply by turning off the chorus."

STEINER-PARKER SYNTHACON MK1


via this auction

"We are delighted to offer this rare and powerful Mk 1 Steiner-Parker Synthacon for sale in full working order.

FULLY OVERHAULED BY JAMES WALKER.

Commission sale. Offers invited.

It's become ever-harder to track down these elusive beasts, especially in Europe. Not only were very few made, those who have them tend not to want to part with them. Going on first appearances, you might ask what is so special about this handbuilt American three oscillator monosynth? On closer inspection, one's eye is drawn to the rows of colourful switches that control the clever modulation routing that is one of the features that makes this synth so appealing.

Nyle Steiner's original Mk1 Synthacon is monophonic, as opposed to the later duophonic Mk2 units: the earlier ones are said to have the edge sonically over. Certainly the reaction to the first demos we put on instagram has been one of considerable excitement at the noises coming out of this machine.

CONDITION: In good cosmetic condition for its age. There are some signs of age to the face, including small spots of oxidation and minor staining in places. Woodwork has some wear. See photos for more information on cosmetic condition.'

Roland Juno 60 Analog Synthesizer Collector Grade W/ Original Case


via this auction

Not sure about that "slight stickiness" mentioned below though.

"Roland Juno 60 in virtually unmarked and unused original condition

There are almost no signs of wear or markings throughout

The jack pots show no signs of corrosion which is a sign that the unit has been well stored over the years and that the internals have not been compromised.

The underside is unmarked indicating that it probably hasn’t been out of its case for long. The red cap is still on the DCB port and the original plastic is still on the serial plate

This is the best example we’ve ever seen and we’ve literally handled hundreds over the years.

This unit has a slight stickiness throughout which will easily clean off but we have decided against cleaning it. Not sure what it is but many of them have the same stickiness about them.

It’s presented in its original state."

Vintage Casio AS-110 Keyboard Amplifier


via this auction

Never seen one of these before. Small bit of synth history right there.

"Nice fully working Casio AS-110 Keyboard Amp - 30 Watts.
Went over this and cleaned it up. all is working, some minor pot scratchiness,seems to lessen with use.
This appears to have been a complement to the Casio CZ Series.
Has 2 front as well as rear line input, a 1/4 microphone input (higher gain) as well as a tremolo, and all the other usual front panel knobs"

Yamaha Tenori-on Step Sequencer/ Synthesizer


via this auction

"Yamaha’s Tenori-on is a really fun and unusual piece of electronics. The software included allows you to program your own sounds via the SD card ( not included) but any standard one works. It’s in good condition. No dents. All the buttons on the front are operational. All the lights in the back work. I am including a plexiglass stand with the tenori-on. It has an awesome clock function when you are not making music and looks great in the stand at night."

Serge TKB by Random*Source, patch example #1


Published on Aug 25, 2018 fonitronik

"A simple patch idea for the new Serge TKB by Random*Source. It uses the internal glide function (row B controlls amount of glide for each step of row A) and the pre-tuned semi tone scale of the keyboard that could be used indeendently from the 4 sequencer rows.

With the internal PSU and the super slim boat (rack mountable) this epic module is the classic Serge controller to put in front of your eurorack modular."

Radikal Technologies Accelerator - Karplus-Strong string synthesis - hammer dulcimer


Published on Aug 24, 2018 MIDERA

"In this video - I used physical modelling via the string filter on the Accelerator to create a hammer dulcimer sound (at least that's how it sounds to my ears).

If interested - the second part of the synthesizer showcases actually using the accelerometer to help with rhythmic changes in the tone of the song - check it out and let me know what you think."
