Notes: Really nice boutique analogue synth from JMT, based around a main oscillator with three sub signals, a frequency-synced resonant filter, noise source and three-speed random trigger.

Supplier's Notes:
DNVO-1 is a handmade, compact analog synthesizer from JMT Synth Its primary oscillator can be synced with three sub oscillators, each with a different range, as well as a noise source and wave generator. The latter source can be manipulated with the 3-speed random trigger for effective fluctuations within a single performance. The primary VCO is routed through a self-oscillating filter, which can sync with the VCO's frequency.

Notes: The NOSC-12, from JMT Synth, is a 12 oscillator drone synthesiser, six main oscillators with six sub oscillators. There are frequency controls for each of the oscillators, including the sub oscillators, which also include sync switches for each of the oscillator pairs. Each of the oscillators are mixed together to a 1/4" output jack.

NOSC-12 Features

12 Oscillator Drone Synth
12 Suboscillators, one per Osc
Volume Controls for each OSC
Sync switches for each OSC.

Notes: The JMT RVO-3 is an analog noise synthesiser featuring 2 oscillators. 1 main oscillators with 1 sub oscillators paired to it. Each of the oscillators features their own frequency controls, and sync switches for each of the oscillators pairings allowing a wide range of textures. It has a main VCO with a frequency control knob and a push button allowing a short envelope to control the frequency. Additionally, controls for the waveshapes and stability of the VCO and sub frequency VCO allow for further manipulation of timbre.

Notes: JMT have designed a very complex interplay between the two oscillators, using two different oscillator circuits with different circuit configurations, and two different waveform conversion circuits attached to each. The output is then routed through a circuit that was developed from the SNB-2b, which emphasizes and distorts the bass, mids, and treble, and which have been tuned to work well with this oscillator.

Fine-tuning of circuit part values was performed to obtain a sound with depth as well as intense distortion by fine-tuning the knobs.

This runs on DC 9V negative center or a 9v battery.

Noisy analogue synthesizer oscillator with distortion function that can emphasize HI, MID, and LO.

The oscillator can be input to a VCO with a wide range and a SUB VCO adjustable by LEVEL.

The VCO and SUB VCO are designed to affect each other in complex ways, so a wide range of sounds can be created by subtle combinations of knob positions.

The MODE switch makes the connection between the SUB VCO and VCO more complex, and the LEVEL knob can be used to adjust the level of the SUB input to create different waveform changes.

By fine-tuning the LEVEL, SUB, VCO knob, you can create a variety of sounds by emphasizing high, mid, and low frequencies.

The CV IN jack is a 3.5mm jack. OUT PUT 6.5mm

Notes: The TVCO-2 is an analogue synth that is powered by a single DC9V~DC12V or 9V battery.

By touching the five sensors directly connected to the circuit of the analogue synth oscillator with your fingertips, the tone of the oscillator peculiar to thick analog synths changes in various ways.

Since it responds delicately, the tone changes depending on whether you touch it strongly or touch the sensor with or without touching it, and whether you touch two, three, or a combination.

The top two sensors are connected to the MAIN VCO and the SUB VCO for input to the VCF, so you can use this sensor to change the VCF (filter) with touch sense to create more complex tones.

The bottom three sensors are connected to the circuit of the MAIN VCO. This sensor can make a noisy change directly to the main sound output oscillator, and the way it changes changes with a combination of touches, such as touching it at the same time in combination with the touch of the SUB VCO.

With a simple structure of 2 VCOs and 1 VCF (band-pass and low-pass switchable), you can intuitively operate this equipment to create your own sounds.

The MAIN VCO and VCF have CV IN. By attaching a 3.5mm conversion jack, you can connect from sequencers, analog synths, and modular synths CV OUT for a wider variety of expressions.

Compared to cable patches and switches, subtle changes can be made instantly at the fingertips, so it is a model that can be controlled more sensitively.

This analogue synth runs on DC9V negative center or a 9V battery.

The main VCO can be controlled with FREQ. knob and 3 touch sennsors.

Sub VCO has two touch sensors and effects to main VCO and VCF as CV.

CV INs can recieve CV OUT of other instruments,sequencer, LFO, etc..

Notes: Multi/poly module

Breath-taking analogue-inspired sound with the limitless power of digital technology.

Summary

The multi/poly module takes analogue modelling to new heights, offering musicians and sound designers an incredible fusion of classic analogue warmth and cutting-edge digital power in a compact, rack-mountable module form. Inspired by the legendary Mono/Poly, this revolutionary synthesizer features four oscillators per program, advanced modulation capabilities, and a wealth of hands-on controls, allowing you to craft everything from rich, layered textures to futuristic, experimental tones. The new 19" rack-mountable enclosure has the same controls as the keyed model yet boasts an easily transportable form factor that fits neatly into any studio or desktop production system.

Overview

Inspired by the legendary Korg Mono/Poly, the new multi/poly analogue modelling synthesizer delivers breathtaking analogue sounds combined with extraordinary digital power and flexibility.

Korg is now pleased to introduce the multi/poly module: all of the multi/poly's incredible features and sounds in a compact 19" desktop/rackmount package. With support for MIDI 2.0 property exchange and poly aftertouch, the module is an excellent companion to Korg's Keystage controller. It's also fully compatible with programs from the multi/poly native software, as well as an increasing number of excellent third-party libraries, keeping the updated sounds and software fresh. The new 19" rack-mountable enclosure has the same controls as the keyed model, yet is easily transportable and fits neatly into any studio or desktop production system.

Next-level analogue modelling

multi/poly features redesigned, incredibly detailed filters and oscillators, and advances in analogue modelling that take this technology to a new level. Each voice contains a Virtual Voice Card, where oscillators, filters, envelopes, LFOs, and portamento circuits are modelled to reflect analogue hardware component variations. As a result, each voice can have its own slightly di6erent character, creating rich and naturally evolving timbres

Just like in an analogue synthesiser, voice cards continue to play even if you're not hearing them. Envelopes evolve naturally, meaning if you play a long pad with an extended release time, newly played notes "catch" the envelope at its current state rather than restarting from zero Oscillators and LFOs maintain phase, while resonance continues to ring out. Pitch drift mimics the subtle instabilities of true analogue hardware.

The multi/poly also includes envelope curvature presets inspired by classic synths like the Mono/Poly, MS-20, ARP Odyssey, and Prophet 5. Additionally, analogue VCAs behave di6erently depending on voltage, with varying thresholds for turning on and o6, which has a strong impact on the Amp Envelope's character. multi/poly models VCA responses from the Mono/Poly, MS-20, Prophet 5, Mini, Odyssey, and more, alongside a linear option.

MIDI 2.0 property exchange and polyphonic aftertouch support

All models of multi/poly, hardware and software, support MIDI 2.0 Property Exchange and easy access to Polyphonic Aftertouch - making them excellent companions to Korg's Keystage controller.

Rack-mount and desktop compatible

The multi/poly module is cleverly designed for both desktop and rack-mount use. The front panel is redesigned to fit into a standard 19" width, and the rear jack panel is recessed to allow easy access to cables even with gear mounted directly above. With desktop setups, brackets over a choice of panel angles: flatter for performing standing up, or more upright for working while seated in your studio

Notes: A lovely creative approach to generative synthesis. Dual voices with triangle/square wave oscillators, shift register and envelopes can be patched via banana cables to create unique grooves and drones.

Supplier's Notes:
Double Knot v3

The Double Knot v3 is a small generative synthesizer with two voices and corresponding sequencers. This instrument has a simple architecture which is capable of a wide variety of sounds, including rhythms and drum patterns or textural and grating noise sounds. The interface is made up of knobs, switches, and banana plugs for patching. The two voices of this device each consist of a triangle/square wave oscillator, a shift register sequencer, an enveloper, and a voltage controlled amplifier. A clock sets the tempo of the shift registers.

The voices of the Double Knot are pre-wired, in a linear chain of functional blocks. The patch points are available to route modulations, influencing the simple linear voices. The game of this device is to investigate the relationships between the elements of the synth using the knobs, switches and patch-points.

FAQ

How many banana cables do I need? and what length?

8 or 10 cables around 12" long is a great start.

Can I patch this with my other synth?

Only what is safe for this synth. The banana ports of this device can handle max +/- 8V at all inputs and outputs assuming at least a 1k output impedance in the other device. The response range of the voltage inputs is ~1.2v - 8V (range of a TL07x powered by 9V).

Is this synth good by itself, or does it rely on other devices to be useful?

Some good sounds can be had using this device and a handful of banana cables.
