Polyend Synth - NEW v1.3 UPDATE - New DWA Synth Engine!

video upload by Oscillator Sink

"The Polyend Synth just got a nice firmware update (v1.3) which incorporates a bunch of MIDI refinements, some new grid modes which open up new performance options and most importantly the new DWA engine which is a fun, dual sample based engine with a comb filter that can be approached in loads of interesting ways.

Transparency Notice: Polyend sent me Synth when it was first released for free in order for me to make a release video. I have not been otherwise paid for any follow-up content made about Synth, although I was given early access to beta versions of the firmware.

Polyend Synth

video upload by Luca Longobardi

"Had the pleasure of trying the new Polyend Synth firmware 1.3 ahead of release. The new DWA engine opens up a world of textures — fragile loops, glitchy fragments, resonant feedbacks, all waiting to be shaped. It’s a reminder of how beautifully unpredictable sound can be."

700 FM System x BOSS ME-50 – How Many People Still Use This Forgotten Classic?

video upload by Gm Xe

"The BOSS ME-50 is one of my favorite effects units — simple, expressive, and still inspiring after all these years.

In this setup, I combine the 700 FM System with the Buchla 208C in a four-voice configuration:

One voices from the 700 go straight into the Auratie (fully wet).

One more pass through the 208C’s LPG .

The 208C main output runs through the ME-50 to shape the core sound.

The other two voices pass through the Auratie

In this patch, I use the ME-50 for distortion, modulated pitch effects, and a spacious delay that blends with the Auratie

This is a cross-era collaboration: vintage guitar effects, FM synthesis, and West Coast analog character blending into one ambient/experimental performance."

FM Synthesis - A Practical Guide - Part 2 - Pad Example, Vibrato, Tremolo, Wubs and Wonk!

FM Synthesis - A Practical Guide

"Here's something I've been meaning to get round to starting for ages, a practical guide to FM synthesis. In my experience FM tutorials usually over explain all the wrong things and rarely get as far as the important things like which setting will make usable sounds.

This episode covers using 2 operator 'stacks' to create a 2x OSC like setup, setting up vibrato, tremolo, LFO to filter like wub-wub sounds, 2 types of 'wonk' and a pad example.

The pad sound is inspired by Selected Ambient Works by Aphex Twin. I think more specifically it was inspired by the pad sound from Ageispolis but I haven't tried to recreate it exactly.

(I have a horrible cold at the moment so apologies for my voice!)

MNMPatch - Monome Norns Monomachine Patch Randomizer #elektron #monomenorns

video upload by HANJŌ

"I’ve been deep-diving into Elektron gear for a couple years, and recently that obsession has taken on a new shape through coding on the Monome Norns. I wanted to share something I’ve been working on: a patch randomizer for the Monomachine called MNMPatch.

This is about exploring the untapped corners of the Monomachine’s sound engine. I love the unpredictability that Elektron gear allows, and writing this script became a way to extend that philosophy into my creative process. There’s something magical about letting a machine surprise you.

MNMPatch lives on Norns and lets you selectively randomize pages of parameters (SYNTH, FILTER, AMP, etc.), so you can coax happy accidents or just start from a fresh sonic place. It’s already led me to sounds I wouldn’t have dialed in manually, and will become part of my daily jam ritual."

STEREO ENVELOPE FOLLOWER | ADDAC System - ADDAC220 DUAL ENVELOPE FOLLOWER+

"This is our new Stereo Envelope Follower, an analog/digital hybrid for better dynamic range analysis. The incoming audio signal gain can be set with the [GAIN] control, the signal is then fully rectified and passed through an analog envelope follower with a fixed short attack and decay.

This analog signal is then sent into a 12bit ADC (analog to digital converter) of an MCU (microcontroller unit) from here on the signal is processed digitally. Whenever the ADC detects clipping the [CLIP] led will turn On.

The digitized signal is then passed through a Savitsky-Golay filter for noise reduction smoothing the incoming signal. Next the signal is slewed using the [ATTACK] and [DECAY] controls. The MCU keeps a history of the last sampling points and detects the minimum and maximum values of the signal which reflect the current dynamic range and maps the signal minimum and maximum amplitude to 0V and the maximum voltage detected. Avoiding the discharge of the analog envelope capacitor.

This new mapped signal is then processed via the [RESPONSE CURVE] control balacing the response like one would with a standard AD envelope with LOG/EXP control. The [ENV. GAIN] attenuverter control goes up to x2 amplification and sets the attenuation / amplification factor of the output range, the red led monitors this level. The led uses pwm control for faster response and better visualization of the output signal across the full output range.

Finally the [OFFSET] allows to displace the signal’s voltage up or down.

The [THRESHOLD] control sets the level to compare to the output signal and turns the [GATE] output On when the signal is above the threshold.
The [GATE LED] show the output state.
The [CV OUT] carries the Envelope signal (0 to +10V) while the [INV. CV] Output carries an inversion of the signal (-10V to 0v).
The [AVG. OUT] outputs the average of both Left and Right CVs (0 to +10V) while the [INV. AVG.] outputs the inverted average signal (-10V to 0v).
The [STEREO / DUAL MONO] switch allows to use the left channel controls to operate the right channel for stereo operation or keep them independent in dual mono. In Stereo mode only the Right channel gain will be independent.

Left input is normalled to the Right input."
