Moog Model 15 AM Amplitude Modulation DEMO

Update: original video was pulled and re-published.

"Moog Model 15 AM / Amplitude Modulation DEMO

Amplitude Modulation provides results similar to Ring Modulation and was / is an alternative technique to produce those distinctive timbres on the Moog modulars that didn't feature a Ring Modulator. Of course it works with any other modular system with at least 2 VCAs. Delay and reverb added.

The basic patch shown in the video can be found at page 127 of the Moog Modular Synthesizer owner's manual (2015 re/edition) and is as follow:

VCO 1 signal out to VCA 1 signal input with fixed control voltage (gain) raised to about 40%; VCO 2 signal out to VCA 2 CONTROL (frequency) input; VCA 1 signal out to VCA 2 signal in; VCA 2 signal out to amplifier;

Of course you can also send the VCA 2 signal out to the 907A or 904A filters and then to the amp"

Twenty Years Of Novation Synthesizers

Published on May 3, 2017 Synthtopia

"At Superbooth 17, Novation's booth featured huge illustrations highlighting the history of the synthesizers and a variety of synths from the last two decades.

We talked with veteran Novation Hardware Engineer Nick Bookman, who gave us a quick tour and told us about what made each synth unique."

Erogenous Tones Radar and VC8

"Using the Erogenous Tones Radar and VC8 to gate and modulate sound sources from the rest of the modular rig. Some of the Radars slope generators are triggered by the Tiptop Audio Circadian Rhythm and used as envelopes, and some are cycling and used as LFOs. The VC8 is used as both VCAs for gating rhythmic sounds and as a mixer.

RADAR, from Erogenous Tones, is the one stop shop for Envelopes and LFOs. It is a monstrous octo-slope generator with options for looping envelopes, Attack-Decay envelopes, and Attack-Sustain-Release envelopes. Envelope shapes can be morphed from logarithmic to linear to exponential, with CV inputs for modulation of speed and shape. Also included are switches to adjust how RADAR responds to triggers, analog and digital. In analog mode, it responds like a classic slope generator, with the frequency not held steady when changing the rise and fall times. In Digital mode, it maintains the frequency when the shapes are changed, turning the RADAR into waveshapable LFOs and even audio rate oscillators. There is nothing quite like this modulation machine.

MAKE NOISE MATHS TUTORIAL ~ Eurorack analog computer module

Published on May 3, 2017 once upon a synth

"This is a tutorial of the Make Noise Maths eurorack module. This module is described as an analog computer. It's a CV processor on steroids which can act as an LFO, an envelope generator, a lag processor, a CV mixer, etc. Essentially you have 4 inputs which can be summed, OR'd or inverted as a group. Each one can be attenuated and inverted independently. In addition, two of the channels have rise and far slew rate controls for extra control."

"Fresh out of the box for its first test. 8 hp of goodness to for getting the Nord Drum to behave itself with modular triggers.

The level of incoming triggers/gates are interpreted as velocity when converted to midi. There are 3 selectable scaling curves for this process. You can also increase the sensitivity of the trigger inputs via a jumper on the back. Button on the front panel to mute all channels is a nice performance feature.

Out of the box it has presets for the Nord Drum default midi setup and another for GM style drum synths. These are fully editable. Last setting is remembered on power up.

Little demo uses the original Pamela's Workout to deliver fixed level triggers. These are then passed through a VCA modulated with clocked random voltages to vary their levels to get timbral variations from the ND. The ND comes into the modular via the 4MS dual delay. Modular output is recorded dry.

(The new Pams Workout would probably work even better and need less patching)"
