video upload by GEOSynths

"Out Friday 14th July 2023 I'm back with a follow up Bank for the fantastic Sequential Take 5. Essence Vol 2 contains 128 all new Patches, with emphasis on playable Sounds, not weird Sound FX.

V2 Firmware added some great new features such as OSC 2 to be bypassed from the Filter, Vintage as a destination and many others, which I have fully taken advantage of. Many of the Patches utilise the excellent FM Function for unusual tones.

Here are the next 32 Patches demonstrated, hope you enjoy them and watch out for 2 more Videos.

Happy Nerding's FX AID PRO Sampler

video upload by Happy Nerding

"Sampler" effect added to the Shaper category.
"Gate" - manual or CV controlled signal capture into the buffer
"Time" - record buffer size
"Scan" - buffer read position
Left input is for the signal to be captured, Right input is for the trigger.
The demo shows FX AID Pro's ability to play the notes once 1/V oct pitch CV is routed to the Sample Rate, which should be set to the semitones scale.
The second part of the demo shows a recorded drum loop triggered by the input drum loop itself, which produces different random beats for different "Scan" positions.

Spectral Audio ProTone

via this auction

"The ProTone is a true analog synth from the mid-nineties for the modern MIDI studio. It is monophonic and features two analog oscillators, a beefy resonant filter, flexible LFO, MIDI and CV/Gate control, and a simple intuitive hands-on layout with every control parameter accessible from the front panel knobs and switches.

Each oscillator features saw and pulse waveforms with independent waveform selection, tuning and level. White Noise is also available from VCO1. The oscillators can be sync'd and Ring Modulation can also be dialed in. The filter section allows for either high or low pass filtering and 12 or 24 dB/oct slopes with the usual cutoff and resonance knobs. A fairly standard ADSR envelope can be applied to the voltage-controlled amp, but there's only a decay envelope (Accent) for the filter. The LFO is quite flexible, with six wave shapes plus random, noise or external input. The LFO can be set to modulate VCO1, VCO2, Pulse-Width on VCO1, filter cutoff and panning. A few remaining controls include a Panner, and Slide (portamento) effect.

The ProTone features MIDI I/O and traditional CV/Gate I/O for use with vintage gear. A little too much like vintage gear, however, the Pro Tone does not have on-board program memory. But with such a basic synth architecture and no hidden menus or parameters, the ProTone is a hands-on tweaker's synth - full of fat analog bass and synth sounds with a squelchy filter and competent LFO. Additional features include external VCO and LFO inputs, MIDI controlled volume and frequency cutoff, velocity sensitivity, and stereo outputs. The ProTone makes a cost effective, reliable and unique alternative to many other older vintage dual-VCO analog mono-synths."

Understanding the Octave CAT // Walkthrough of Cherry Audio's latest release

"Cherry Audio's Octave Cat is a virtual synthesizer instrument designed in collaboration with Carmine Bonanno, the original designer of the CAT synthesizer. The 1976 Octave Electronics CAT was an affordable alternative to expensive portable analog synthesizers of the day.

The Octave Cat feature set expands on the original with enhancements including 16-voice polyphony, sample and hold glide, and interchangeable skins.

A secondary panel view reveals dual eight-step classic-style sequencers and studio-quality effects featuring distortion, phaser, flanger/chorus, delay, and reverb. With support for MPE, over 300 expertly designed presets, and extensive MIDI mapping functions, Octave Cat will satisfy both vintage synth aficionados and professional modern music producers.
