OP-1 Deep Dive #3 | DIGITAL is BETTER?

video upload by Oblivion Corner

"Discover the Digital synth engine on the Teenage Engineering OP-1. This mystifying OP1 synthesizer has complex interactions between its four sound parameters: wavefolder, octave, ring modulator / detune and something called 'digitalness'. This video gives you an overview of each parameter in turn and proposes a way to demystify how to tweak your sounds on this OP-1 synth engine and get more out of it. Before finishing off, there's also time to highlight one of my fave sound presets on Digital.

Yamaha TX81Z | Amazing FM Synthesizer | Factory Sounds Demo (HQ)

Update: it appears the full audio in the video was taken from this video. You can find it there.

removed video was uploaded by Simon Le Grec

"Yamaha's TX81Z first went on sale in 1987. The TX81Z is a great four‑operator FM type synth sounds similar to the DX-21 and DX-27. Eight voice polyphony, 128 preset sounds, 32 user and lots of functions hidden behind 11 push buttons.

The rear panel is home to MIDI In, Out and Thru sockets, two audio outputs and an unusual eight‑pin socket used for connecting a cassette recorder to load and save patch data.

In 'Single' mode the TX81Z acts as a single, eight‑note‑polyphonic instrument. In 'Performance' mode it can be up to eight‑part multitimbral, although polyphony is still limited to eight notes.

There are 128 preset patches, and 32 memory slots are provided for storing user patches. There are also 24 memory slots in which Performance data — ie. settings for volume, polyphony, MIDI channel, and so on for each of the selected voices that make up a 'Performance' — can be stored.

Analog Mafia RC-808 “Drum Rap” Contest

The following is in via Analog Mafia. You can find details on the contest here.

"RC-808 is a drum synth that can do the rap all by itself. In another words, we will go back to the days of the talking drums. It would be great if you could have a listen to the files.

Giving articulation ability to drum sequencers was actually a part of the Roland history ever since Don Lewis connected an expression pedal to add volume level accent to give variation to a primitive preset patterned rhythm box. This lead Mr Kakehashi to implement "Accent" as a parameter of rhythm machines.

When Mr Kikumoto designed programmable drum sequencers and MIDI protocols, he wondered why the sequencers onboard drum machines don't have any pitch nor duration parameters. Because they are non-tuned percussion? But then synths can provide frequency and envelope curves to match your needs and tastes. Isn't this lack of these parameters result of prejudices or stereo types that still confines the drum sound expressions to a certain notion only?

This is the reason why the RC-808 Standalone edition has a small piano roll style sequencer. With full fledged general purpose 8 partial synth engines per instruments, you can create both tuned and sustained sounds that can be used for percussive purposes. For instance, this offers "open and close" sound variation to not just hi-hats but to any other instrument you can imagine, like "open and close bass drum" you hear on the demo files here.

Recently, as Kikumoto san was reviewing HipHop and Rap music, he found rappers' rhyme and flow concept somewhat resembling his RC-808 concept of providing further expression to drum sounds.

Inspired with the rhyme and flow concept, he is thinking of expanding this scheme to shed new light to drum sound expression, not just to hiphop and rap, but to all kinds of music genre, with a concept of Drum Rap like MC talking drum so to say."

Reface DX improv 08/21

video upload by Floyd Steinberg

"Here's a short Reface DX improvisation. I challenged myself to use only the keyboard and a multitrack recorder, so no arpeggiator, quantizing or corrections after recording. This is made from 8 stereo tracks I improvised one after the other. The pad sound and the lead went through a Strymon Nightsky reverb pedal."


New Prototype 36-Voice Poly Analog with Touch Sensitive Keyboard

video upload by i make synths

New prototype 36-voice poly analog synth from i make synths.

"It's signal goes through an analog phaser and reverb. Everything is do-it-yourself, including the touch sensitive keyboard. It does not have any filter yet, but coming up next."

Additional details to follow... 

Update via i make synths:

"This is DIY project for personal use only, not a commercial product.
Oscillators are op amp/MCU based, 36 separate sawtooth oscillators. One oscillator per key. 36-voice polyphony.
Output goes through analog phaser circuit (that is also DIY) and is op amp based. Keyboard is touch sensitive, but it is not calibrated yet. Filter section (low pass) is to be added later on. Probably filter per key."

Macumbista Fuzztone SoundBox

video upload by Chris Menes Sound

"A short demo of my 'Macumbista' sound box. Built at a workshop in London with sound artist, Derek Holzer a few years ago. It is a simple amplifier circuit with a speaker. The spring has a contact mic attached to it and it generates feedback when it's placed on the speaker. The touch points connect to various parts of the circuit so you can circuit bend it with your hands."

"Macumbista Fuzztone SoundBox Synthesizer Super Rare

Purchased directly from Derek Holzer of Macumbista

Rarely used and in perfect condition

Comes with Spring/Contact Mic

This was over an 8 month waiting list and they are no longer being made

Runs on a 9 volt battery

This has touch points and can be played alone as a noise source or you can use the contact mic or plug any line level source in and create

Full details from the Macumbista Website:

A new generation of the SoundBoxes is born, combining the touchable body contacts and high-gain portable amplifier from the original design with a nasty distortion with enough controls to keep your fingers busy wiggling for a long while.


* Large, high-efficiency (read: LOUD!) 12cm speaker
* High-gain input, suitable for contact microphone, electric guitar, etc. (Line level signals can be attenuated if clipping is not intended.)
* Line output
* Neutrik 6.3mm (1/4 inch) jacks on both input and output
* Four-control, switchable, extreme[!], vintage hand-selected Germanium transistor distortion
* Six “circuit-bending” touchpoints
* 9V battery operation
* Includes a resonant spring contact microphone.

This SoundBox could easily be used as a portable guitar amplifier with built-in distortion, for example, or can be used as an instrument in it’s own right to create a wide range of electronic sounds and textures.

The sound of this instrument is quite similar to what can be heard in the following video (however the video was done with the SoundBox and FuzzTone distortion pedal as separate units). Through the creative use of feedback, as well as the CHP and SQZ settings on the pedal, generative tones and chaotic patterns can emerge"
