SpeakJet first test

video upload by Polaxis

"Working on a new prototype: Speakjet vox, hosting the almost vintage chip of the same name. Here hosted inside the Terminal. I am playing with different modes: priority to the gate, priority to speech, and queuing phonemes. While queuing phonemes, the chip it triggering the snare when the buffer is half full, giving a nice feel to the beat"

Also see this post with Speakjet on Emy in 2018. The chip was also featured in the FLAME Talking MIDI Talking synth. You can find SpeakJet posts here.

PolyRotas, Opera Rotas transforms into a polysynth (Megadrive/Genesis based)

video upload by ZElTGElST

"Opera Rotas has a new firmware that transforms the drum machine into a fully 9 voice polyphonic synth based on true, vintage Yamaha FM chips.

It´s a bit like transform a Sega Genesis/Megadrive into a playable synth with a midi keyboard.

If you have an Opera Rotas (revision 0.9 or higher) you just need the new firmware, available in my stores. So you can have both firmwares with one machine: the classical Drum Machine and this new PolyRotas."

SCHLAPPI ENGINEERING Boundary Overview Part 1

video upload by SCHLAPPI ENGINEERING

"The Boundary is a multi-function cycling slew and four quadrant VCA. In this video we go over some basic envelope/vca usage, bouncing ball fx with the BOUND input, and using it as a clock or frequency divider."

"The Boundary is a multi-purpose modulation and signal control center. It consists of a cycling slew and a four quadrant multiplier (VCA).

The cycling slew (which can be used as an envelope or LFO) has individual control over rise and fall, rate and shape, as well as dedicated inputs for trigger, slew (for gates or pitch cv), full wave rectification (for envelope following), and a unique BOUND input which allows for bouncing ball effects and additional modulation of the envelope.

The four quadrant multiplier is an OTA design and is usable as a VCA or ring modulator with a soft limiter on the output to tame extreme signals or push into distortion.

LFO and modulation oscillator (from cycles measured in minutes to high audio rate)
Trig input can be used for attack-decay envelope
Slew input can be used with gate signals for attack-release envelope
Slew input can also be used as portamento for v/oct signals
Rectify input has a full wave rectifier to act as a high quality envelope follower
Bound input allows for unique bouncing ball effects and combined AM/FM modulation
Trig input can also be used for voltage controlled frequency division at clock or audio rate
EOR output can be used for gate/trigger delay
Four quadrant VCA allows for ring modulation
Soft limiter on the VCA output allows for taming or distortion of wild signals

All analog design

Summer session at Mos Lab studio

video upload by Nr Synth

"Après lui avoir présenté le Big Ancestor ARP, Seb et moi avons improvisé juste pour le fun avec nos machines. Puis le miracle est arrivé: Jean -Luc Briançon a transformé ces sessions en un véritable morceau de Berlin School (qui n'est pas sans rappeler les live de TD de le tournée américaine de 1977).
After showing the Big Ancestor ARP, Seb and myself improvised live just for fun with our synths. Hopfully, a miracle is become: Jean Luc Briançon created a real Berlin School song with these sessions (very close to the TD lives from 1977)."

TR707 blinkenlights Screen Replacement for the Roland TR-707

This one is in via @dylab

via synth.ewancolsell.com:

"One of the bad things that can happen to a TR707 is the LCD becoming Damaged, either by exposure to too much sunlight, liquid damage, bad luck, etc.

Whilst it is entirely possible to use a TR707 without looking at the screen, it isn't much fun. after repeatedly hearing people on the internet, searching in vain for replacement tr707 screens, i decided to have a go at making a replacement. my tr727 screen works perfectly, so it's a perfect opportunity to develop a replacement.

i was originally going to do this with an OLED, but finding a cheap one the right size was kind of hard. So i decided to go down a different path. Lots of little Leds and a couple of Led controller chips.

There are few question marks for this project still, especially regarding power consumption, i'm going to have to determine experimentally how little power i can get it to consume, by running the leds at the lowest possible duty cycle.

Also tbd is a nice way of attaching it to the TR707 without drilling holes in it.

This is only part of the screen replacement project, the other half is the MCU that will decode the data from the TR707 CPU. i'm sure that's going to have a few surprises."

Novation & Sequential Synth Bundle Giveaway

via Novation, where you can enter for a chance to win the giveaway:

"We've teamed up with our Focusrite Group family member, Sequential, to bring you the ultimate synth and controller bundle worth over $1,900 USD.

(1) Novation Launchkey 37 [MK3]
(1) Novation Circuit Tracks
(1) Sequential Prophet Rev2 8 Voice desktop synth

Launchkey is Novation's intuitive and fully integrated MIDI keyboard controller for making tracks in a DAW and with external hardware, designed to give you everything you need to create and play your music. Made for creators of all abilities, Launchkey gives you inspirational tools to expand your musical vocabulary. Scale and Chord Modes and a powerful arpeggiator push your musical creativity and help start new ideas. Custom Modes and a full-size MIDI output transform Launchkey into a powerful centrepiece of any music-making setup.

Circuit Tracks is the agile groovebox for creating and performing electronic music without resistance. Two refined polyphonic digital synth tracks expand your sonic capabilities, and samples across four drums tracks can be loaded via microSD and shaped to perfection. Builtin FX polish your sounds. Two dedicated MIDI tracks and a built-in battery make it ideal for multi-device setups and for creators on the move.

A modern classic reinvented. The Prophet Rev2 desktop module by Sequential is just as powerful and easy to use as its counterpart, the Prophet Rev2 keyboard. The module has the same controls with the same ease of use as the keyboard version. Best of all, it sounds just as awesome, because it’s exactly the same on the inside — Dave Smith’s reimagining of his now-classic Prophet ’08 poly synth. The Prophet Rev2 retains all of the key features of the Prophet ’08 and expands on them. It has twice the polyphony, twice the mod matrix, waveshape modulation on all waveforms, digital effects per layer in stacked or split voice mode, a polyphonic step sequencer per layer, and more. The result is a true analogue powerhouse.

This giveaway ends September 14th and is available to participants with a US mailing address only.
