GX1 Wave Level Mod Demo

Uploaded on Jan 30, 2019 sequentix

Spotted this one on sequencer.de. Apparently there was a software editor for a Kontakt GX1 pictured below. If anyone has additional info on them, feel free to leave a comment.

via robotmakers on Muffs:

"Here's a Kontakt instrument I put together that models the Yamaha GX-1, with its quirky interface and idiosyncratic features. The instrument is based on a set of sampled analog waveforms processed through the filter and modulation engine of Kontakt 5.0. This latest version of Kontakt includes a variety of greatly improved filters, including a 12db per octave set of HP, BP and LP filters that sound surprisingly close to the GX-1's (I used MOTM-485s to compare). There are 25 pages (!) of Kontakt KSP code behind this thing, and two interface levels, portaying the unique GX-1 Programmer and a selection of other controls (e.g. LFO labeled oddly as Sub-Oscillator). This is work-in-progress, and currently uses samples of a Moog 921B VCO rather than a more representative oscillator. The next step will be modeling the VCOs more closely, among other things."

"Modular or Stand Alone Synth, with Dual Independent Oscillators, Dual Lowpass vactrol-based gate/ filters and Dual Function Generator. Snoopy can be played as a stand-alone instrument with its core Complex Waveform Oscillator, filter and VCA functions with amazing power in a compact
design, or integrated into a larger complex system. With its Dual Lowpass Gate consisting of two independent vactrol-based gate/ filters in the classic Buchla format, Dual Function Generator with two independent envelope generators with VC attack and decay, and ability to cycle and perform as an LFO, MIDI, comprehensive CV and USB control to allow interfacing with all formats including EuroRack, and the most
desirable and unique timbre in the pages of synthesiser history, Snoopy is Buchla Power for now and the future.

Complex Oscillator: 2 independent oscillators that can be linked for FM/AM modulation effects

Dual Lowpass Gate: 2 independent vactrol-based gate/filters in the classic Buchla format

Dual Function Generator: 2 independent envelope generators with VC attack and decay, with the ability to cycle and perform as a LFO

MIDI-CV interface: 5-pin and USB MIDI input for a single synth voice with 1-1.2V/oct voltage conversion, jack/multiple conversion and scaling buffers for interfacing

More CV buffering, scaling, and 1-1.2V/oct conversion, jack/multiple converters and Pulse-Gate and Gate-Pulse converters interfacing to other systems.

Snoopy can be configured in a standard Buchla-style synth voice using the modulation oscillator to modulate the Primary oscillator, or even 2 independent VCO-VCF/VCA voices. Even in this compact package, there are limitless sounds that can be created in real-time.

Integrate with your synth or external audio sources and use Snoopy’s classic Buchla filters and modulation sources for unique effects."

Intellijel Atlantis SH-101 Style Eurorack Synth Voice

"The Intellijel Atlantis was constructed in the spirit of the Roland’s legendary SH-101. Like its inspiration, the Atlantis excels at rich bass sounds and soaring leads. However, unlike the SH-101, the Atlantis ditches the sawtooth core for a triangle core, designed by David Dixon, sourced from the Intellijel Dixie. The decision to add a triangle core means that the Atlantis excels at FM style sounds. The modulator oscillator can be switched from an LFO to a VCO, with both oscillators able to track at an astonishing 8 octaves.

The module features a handy mixer section that allows for the convenient mixing of waveforms. Additionally, users could patch the modulator oscillator into this section to use the Atlantis as a more traditional dual oscillator.

The module’s filter section is essentially a Roland style cascaded 4-pole multimode filter that can be switched between low-pass, band-pass, and high-pass. The accompanying LP switch decreases the amount of resonance in low-pass mode, enabling the creation of deeper, fatter sounds.

Atlantis’s envelope section consists of a traditional ADSR envelope with an optional looping mode and the ability to be activated by an external gate. The output VCA feeds directly into an advanced clipping circuit that can be utilized to achieve a nastier/grimier sound."
