"Control Synthesis Deep Bass Nine - DB9 Analogue Synth

This is a 1U rack sound module originally made between 1994 - 1999

It is an analogue bass synth modelled on the Roland TB303. It has Square / Pulse waveforms and a set of shaping controls similar to the 303 for acid squelches etc. As a lot of reviews state it is not that similar sound wise to the 303 however it has a really nice analogue sound perfect for bass or lead sounds. It also features an external input so you can use the filter to shape the sounds and also a CV/Gate I/O for controlling older non midi synths. This works on Midi or CV inputs. Via midi you can also turn portamento on or off..."

Mutable Instruments Anushri Analog synthesizer

"Fully assembled and calibrated

(design by Mutable Instruments)
Anushri is a monosynth like no other. In addition to its analog VCO/VCF/VCA and digital modulation sources, it includes a fun and immediate note sequencer with step-by-step recording, and a gritty 8-bit drum machine with a truly original control interface.

Mutable Instruments did what no other synth manufacturer dared trying before: enrich the VCO with an auxiliary digital oscillator, which can be used as a FM source, a sync signal generator, or – if you don’t mind having some digital signal flow in the audio chain – an additional detuned audio source for fattening the VCO sound.

Built-in sequencer and arpeggiator

Anushri’s built-in arpeggiator easily transforms chords into complex basslines and acid patterns with accent and slides. But the real fun starts when you use the built-in sequencer. Its interface is refreshingly simple: press rec, input notes on the MIDI keyboard or press the rest/tie buttons, press rec to finish, then start. The sequence can even be transposed from the keyboard.

Built-in drum machine

Anushri comes with a truly original rhythmic section. Original in sound, using 8-bit analog-style synthesis with integrated bit-crusher (What? A 707 sampled through a Mirage?). Original in interface, since it is “programmed”, or rather sculpted with knobs rather than x0x style switches and LEDs. How does it work? 2 knobs control morphing through different structures of drum patterns, and 3 knobs control how sparse/dense the pattern is for bass drum/snare drum/hi-hat, allowing you to create fills and variations at the twist of a knob.

…to the modular world

In addition to its standard 6.35mm audio output / input, and MIDI connector (with sequencer/drum machine output), Anushri comes with twelve 3.5mm I/O connectors on its front panel, for easy integration with a modular setup. Filter the drum section through an external unit, route the VCO CV to a second VCO and bring back the signal to the mixer; or add extra modulations on VCF, VCA, VCO frequency and pulse-width…
