Presets of the Mighty SY99

video upload by CGMAGIK

"Released in 1991, the Yamaha SY99 was the SY series flagship. It used RCM synthesis (Realtime Convolution and Modulation) synthesis combining AWM (Advanced Wave Memory) and 6 Operator AFM (Advanced Frequency Modulation) Synthesis. RCM’s unique modulation capabilities enabled AWM samples as modulation sources for the AFM engine.

The SY99 featured a few significant upgrades over its sibling, the SY77:

A larger 76 note keyboard with zoned aftertouch (channel aftertouch programmable to affect notes played either above or below a split point independently)
Three times the amount of AWM waveforms (2 Mb in SY77 and 8 Mb in SY99)
-500 Kb of battery-backed user sample RAM, expandable to 3 Mb
-Upgraded SPX900 level multi effects
-Upgraded master keyboard functionality"

2/20/26 (2 clips, tune knob) Pasco Scientific 9301 & WA-9307A + Yamaha EM-100

video upload by Cfpp0

"Two Pasco Scientific 9301 dual function generators are functioning (themselves and each other). The lower function on the right 9301 is modulating the top of both 9301s. We had our WA-9307A Fourier Synthesizer modified with a tuning knob, which I am turning back and forth in the first clip (chasing two pencil lines). The WA-9307A is being modulated through the right 9301. The spring reverb, panning, and a little EQ is from the Yamaha EM-100 mixer."

Ambient Electronica with Game Boy Advance and OP-1 field | Praise 2026-02-21 by atnr

video upload by atnr

"Ambient electronica featuring gentle synth tones, electric piano, and Game Boy sounds.

Created with Game Boy Advance, ‪@teenageengineering‬ OP-1 field, ‪@YamahaSynthsOfficial‬ CS01, and norns shield.

On the Game Boy Advance, sequences are programmed using Stepper. The sound runs through monotron DELAY, where delay is applied and the filter is manipulated in real time.

On the OP-1 field, a 32 bar synth harmony loop is played and processed through ‪@ChaseBlissAudio‬ GENERATION LOSS MKII and LOST+FOUND.

On the CS-01, I use a slow attack patch with the waveform set to PWM, performing while adjusting PWM speed and modulation.

On the norns shield, electric piano phrases are recorded into graintopia, processed granularly, and played back.

All devices share the same tempo, but no sync cables are used."

video upload by atnr

"Ambient Engine (macOS)
https://store.atnr.net/downloads/ambi...

A piece built around piano, synth, and granular-processed chorus textures.

The piano is performed on the YAMAHA CP-88 with deep reverb applied.

On the volca fm2, a synth pad is played and processed with deep reverb through ‪@strymon‬ blueSky.

The chorus samples are imported into Ambient Engine and played back with randomized playback ranges. Modulation is applied to the filter, and additional variation is created using the built-in looper and delay effects."

Experimental Modular Footwork with TENORI-ON | Roar 2026-02-14 by atnr

video upload by atnr

"An experimental footwork piece created with YAMAHA TENORI-ON and a modular synthesizer.

In the modular system, Plaits serves as the main oscillator, while MIDI triggers the Quad Function & Trigger Source. The sound is split into two paths: the direct output of Mutable Instruments Plaits and a version processed through a Clouds clone. These two signals are mixed in stereo. The final output is routed through ‪@ChaseBlissAudio‬ LOST+FOUND, adding reverb and delay.

On the TENORI-ON, rhythm patterns are programmed in real time, with occasional delay applied via MOOD MKII."

Music Mouse Explained | Laurie Spiegel on Algorithmic Composition (1987 Archive)

See the Music Mouse label for additional posts.

"In this 1987 episode of Midnight Muse, composer and programmer Laurie Spiegel discusses Music Mouse [demoed with a Yamaha TX816], her groundbreaking interactive music software, and answers live call-in questions from viewers.

Laurie explains how Music Mouse works, why it was designed as an intelligent musical partner rather than a traditional instrument, and how algorithmic systems can support creativity without replacing human expression.

He Hates This Synth Because…

video upload by Anthony Marinelli Music

"In this video, I pick one thing I think I hate about 12 classic synthesizers—and then follow that feeling wherever it leads.
We’re talking about legendary instruments:
Minimoog, MS-20, Prophet-5, Jupiter-8, ARP 2600, Moog IIIc ('Plantasia'), Oberheim 4-Voice, Oberheim OB-X, Synclavier III, Elka Synthex, and Yamaha CS-30.
What starts as frustration with a workflow choice, a knob, or a design limitation slowly turns into something else entirely.
Along the way, I realize this video isn’t really about hating synths at all. It’s about relationships.
Every one of these instruments has limitations—and so do we. In any good relationship, not everything is perfect. But when you stop fighting what something isn’t and start understanding what it is, those limitations can become the very thing that leads you somewhere creative and unexpected.
Instead of endless options, boundaries create focus.
Instead of frustration, they create identity.
And in learning to understand these instruments more deeply, I ended up learning something about myself.
This is a video about synthesizers—but it’s also a small morality tale about creativity, acceptance, and finding freedom inside constraints.
Let me know in the comments:
Which synth do you love… even though it drives you crazy? 🎛️"

Bizarre Love Triangle/New Order (Circuit Tracks & MiniDEXED version)

video upload by Guinan

"‘Bizarre Love Triangle’ from 1986 is first off the rank for my ‘New Order February’ recreations.

I love this perfect slice of dance-synth-pop and I was keen to get the DX7 bass intro as close as I could. Earlier this week I’ve been showing the tiny $75 Raspberry Pi synth, MiniDEXED, that I built to add this vital ingredient. If you are interested check out the video showing more details, • I made a synth for $75* ! (*excluding tar... [posted here]

A couple of very clever folk identified what I was cooking up!

The MiniDEXED was sequenced from the MIDI tracks on the Circuit Tracks and routed into the audio in to add effects from the Tracks. All that you hear was programmed into the single Circuit Tracks and no further additional synths or processing were done to the sound – it’s straight audio out recorded direct into a Zoom L6.

The arrangement was taken from several versions posted on Musescore and compressed into the 4 melodic tracks and rhythm. Thanks to everyone who posts their transcriptions there.

I hope you enjoy the track as much as I did making it. Stay tuned for more New Order recreations and reworkings for the rest of this month.

(Ableton Move version coming in just a couple of days...I'll post a link here when it's live).
