Roland TR-909 w/ Mods

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

"This 909 contains modifications (thanks to Colin Fraser) to the kick as well as the high-hats, to give you far more flexibility that what is traditionally offered by a typical 909. The mods to the kick are the group of three rotary controls above low/mid Tom controls. As you can see, the same rotary knobs that were on the original were used on the mods. Mods to kick add three new controls:

- Pitch: controls the frequency of the bass drum oscillator
- Drive: allows waveform adjustment from normal to square, for hard clipped sounds
- Tune Depth: varies the amount of the initial pitch sweep (decay is set by TUNE control)

These mods literally give the 909 the ability to produce any kind of kick imaginable, from overdriven, to deep, pulsating kicks.

The hi-hats mod gives a tune control for the hi-hats that functions the same way as the tune controls for the crash and ride cymbals. This adds a lot of depth and flexibility.

More details on the mods can be found here"

Access Music Electronics' first VA synth. Kind of interesting that it's labeled Simulated Analog rather than Virtual Analog. When did VA become the reference norm?

Dawless Jams with Novation Circuit, Roland Boutique, Roland AIRA

Published on Apr 2, 2017 Fantastic Beats and Where to Find Them

"Getting together with some synth-friends for a JAM! Starting off with a combination of JP08 and System-1, then Circuit takes over sequence duty and plays back arp-city to both synths..... TR-8 comes in hard and heavy and then JU-06 with that bass in yo face!

LETS JAM!"

MFOS (inspired) DIY Analogue Synthesizer Experiments.

Published on Apr 2, 2017 Michael Maggs

"These are loosely based mainly on Ray Wilsons' 'Music From Outer Space' synthesizer designs There are other designs too. It's just me having fun and working towards a monster analogue synthesizer.

LFO based around a CD40106 Hex Schmitt trigger:

VCO can be found here:

VCF can be found here:

The Step Sequencer is based on the CD4017 based decimal counter IC. In this instance I use only the GATE for triggering at around 5V:

This is Wavetable Synthesis - using Black Wavetable VCO

Published on Apr 2, 2017 Carl Mikael's Cabinet of Curiosities

"Wavetable synthesis gives you easy access to timbres that might be complex to construct using analog synthesis. By using modulation, there can be lively timbral variations relatively easy.

This tutorial shows off the basic concepts of a wavetable oscillator using the Erica Synths Black Wavetable VCO. Modulation and sequencing by the excellent CV sequencer in Elektron Analog Keys.

SEGA「SPACE HARRIER」より「MAIN THEME」をFM SOUND CHIP”YM2608”で演奏しました♪

Published on Apr 2, 2017 NozMusic

Kicks in at :19.

"1985年に、セガから体感ゲーム第２弾としてリリースされたシューティングゲーム「SPACE HARRIER（スペースハリアー）」より「MAIN THEME」を、SPFM Light+OPNA(YM2608)モジュールを使って、YAMAHAシーケンサー「QY700」のMIDIシーケンスで演奏させてみました。"

Googlish:

"Using MAIN THEME", SPFM Light + OPNA (YM2608) module from the shooting game 'SPACE HARRIER (Space Harrier)' released as the second game of Sega from the Sega in 1985, YAMAHA sequencer 'QY 700' I tried to play with MIDI sequence. "

via Wikipedia:

"YM2608, a.k.a. OPNA, is a sixteen-channel sound chip developed by Yamaha. It's a member of Yamaha's OPN family of FM synthesis chips, and the successor to the YM2203. It was notably used in NEC's PC-8801/PC-9801 series computers.

The YM2608 comprises four internal modules:

FM Sound Source, a six-channel FM synthesis sound system, based on the YM2203
SSG Sound Source, a complete internal implementation of the Yamaha YM2149/SSG, a variant of the popular AY-3-8910/PSG for producing three channels of square wave synthesis.
ADPCM Sound Source, a single channel for samples in 8-bit ADPCM format at a sampling rate between 2–16 kHz
Rhythm Sound Source, a six-channel ADPCM system, enabling playback of six percussion "rhythm tones" from a built-in ROM
The FM Sound Source module includes six concurrent FM channels (voices, twice as many as the Yamaha YM2203), four operators per channel, with dual interrupt timers and an LFO. It also includes eight possible operator interconnections, or algorithms, for producing different types of instrument sounds.

The SSG, or Software-controlled Sound Generator, is Yamaha's YM2149 programmable sound generator. The YM2608 includes the SSG's 3 sound channels and dual 8-bit GPIO ports.

The YM2608 is used with a YM3016 stereo DAC..."
