Tags: Snare drum module

Notes: What does this do?

This is a mini analogue synthesizer that produces snare drum sounds. Inspiration was taken from the 5U Cor Synth DR02 module. Only the flow chart was studied and used to create this BLM product. VCV Rack was also used to simulate and test the building blocks.

Most of the circuits contained in this product are from other blue lantern module designs.

Some of the building blocks:

-2 1V/Octave Triangle Core VCO's
-2 Sine Wave Shapers
-4 Envelope Generator
-White Noise Generator
-High Pass Filter
-Tone Filter
-2 VCA's
-Mixer

The goal of this module was to recreate some of the more exotic electronic snare sounds.

You're not getting another Roland 'TR' module with the Gimme Some Snare Drum. All the building blocks contain full analogue circuitry, like OTA chips, and Op-amps. No vintage transistor based (Bridge T Oscillator) circuits are used in this product.

The best description as to what the kind of snare drum sounds this module can produce is something comparable to:

an Electribe Korg ER-1, Simmons Snare Drum, and the Mattel Synsonics.

Notes: The SD909 adapts the iconic TR-909 snare drum and noise generator for use in the Eurorack modular synthesizer format. Tiptop painstakingly tested the module in their lab to sound like a fresh machine coming off of the assembly line back in the 80s. On top of the original circuit, Tiptop have added new features that expand the palette of what can be produced with this analogue circuit.

The sound of the SD909 consists of two main sections: the binary noise generator and two modulated triangle oscillators. The oscillators provide the low end punch while the noise makes up the upper sonic spectrum, resulting in a combination that makes the 909 snare sound so rich. In the SD909 module, the noise generator and oscillators are variable and voltage-controllable, pushing the circuit beyond its original boundaries, offering new sounds and many variations of the original tone. The panel also has markings to guide setting the knobs to reproduce the vintage snare sound of the original machine.

Just like the other drums in this series, the SD909's high-powered output gain stage allows further enhancement of the sound through distortion and clipping. Tiptop have designed a dual pulse-shaper circuit on each gate input so you can trigger your SD909 with Trigger/Gate signals from step sequencers, clock dividers, or any other pulse/clock sources. Also, the SD909 is equipped with access to the MIXZ MixBus, matching the rest of the Tiptop line of percussive modules.

TR-909 is a Trademark of Roland Corp Japan

Notes: Black edition of Hexinverter's 808-inspired drum bundle. Kick, clap, snare and hat modules recreate the iconic sounds of Roland's legendary analogue drum machine, all updated with modular features.

Supplier's Notes:
Introducing four re-issues of classic Hexinverter drum modules - the Mutant Bass Drum, Mutant Snare, Mutant Clap and Mutant Hihats! These modules are perfect for anyone with a taste for classic TR808/909 sounds, but with a greatly expanded tonal range with voltage control over parameters and, of course, optional high distortion!

Notes: Designed by Hexinverter, from classic electro snares to warping, alien percussion, the Mutant Snare is a radical departure from the static sounds of the TR-808.
