Modular Synthesis 101 | Part 5 | Modulators

"Audio + Video by G-Storm Electro c. 2025

Continuing my introductory series of videos on Modular Synthesis 101. Today we'll look at some classic modulator utility modules in Modular synthesis with some simple examples. You already know about 2 modulators: Envelopes and LFOs. Along the way we'll be changing any Lowpass filter to a Highpass. From the last video we also know that a VCA can be used as a Modulator. So it probably won't surprise you there is a special Modulator can behave similar a VCA.

Viewing the the complex waveforms of the Gleeman Pentaphonic

video upload by Vintage Synthesizer Museum

"After posting some pics of the Gleeman Pentaphonic Friday, someone in the comments asked what ‘Comp1’ and Comp2’ were in the oscillator section were referring to. Well, according to the manual: The first two waveshapes are COMPlex 1 and COMPlex 2. These are two new complex waveshapes not usually found on a synthesizer and are included for their unique harmonic qualities. Here, we’re viewing the waveforms with the Korg NTS-2 oscilloscope. We currently have one of these oscilloscopes in the studio. If you’d like to see one of these at each of the mixer sections in the studio, let us know."

DIY Oscillator using PIC12F1571

video upload by alloutofsync

"I used this weekend to create a square wave oscillator that operates with the PIC12F1571, which is an extremely affordable CPU available for just $0.71 each.

Since it was my first time using PWM, I spent an entire day generating a square wave at the desired frequency. The required settings and their interconnections were so complex to me, so that I had to carefully investigate each one as I went, which was quite challenging.

The next day, I spent working on ensuring that the output sound smoothly followed the CV input. To convert the CV input into a frequency assuming 1V/Oct, exponential calculations are typically used. However, the PIC12F1571 has limited program memory, so I couldn't use a floating-point math library. I had no choice but to approximate the calculation of powers of two using a Taylor series expansion and rely solely on integer arithmetic. Initially, I approximated up to the second-order term, but the accuracy was insufficient at higher frequencies. Eventually, I extended the approximation to the fourth-order term, which gave excellent results.

While testing with the Pico3 sequencer, I noticed that when the RATE was set to the maximum, the output failed to keep up with the changes. Increasing the PIC's clock frequency from 1MHz to 4MHz resolved the issue, and it followed the changes without any problems.

At this point, about 70% of the program memory has already been used, so I'm not sure how much further I can expand. At the very least, I want to implement duty cycle adjustment. If possible, I’d also like to use an additional PWM channel to detune and combine the signals for richer synthesis."

BMC114 Diode Break Shaper Schematic Walkthrough

"This module splits a waveform into 5 bands of voltage ranges and then mixes those bands together with attenuverters. The break points between bands can be controlled with external CV. This allows for harmonically complex outputs that remind me of strings and woodwinds.

Compatible with 12V or 15V systems. The Pots are PCB mounted, but all jacks are off-board."

"I was asked a couple of times how does the Wave Multiplier works. I did this video hoping to answer the question the best I can.
Disclaimer: I'm not an influencer, nor I'm asking for money on Patreon. I don't have the equipment, nor I can spend days on making a video, so be aware that the quality of the video content might not meet your expectation(s) or even 2024 online tutorial standards. Myself I watch from time to time demos of new equipement from people I respect for the quality of their product demo or tuto ("loopop" comes first in mind). I have no idea how much time they spend on the making, but I can't imagine it not being enormous. Personally I'm simply trying here my best to share my experience and what I discovered about the Wave Mutliplier on the Synton Fénix II and IId, hoping it can be useful for all friends here watching my channel."

3D t-rex drawn on an analogue oscilloscope 🦖

video upload by Hexial

Curious if what we are hearing is the drawing or modulating the drawing per the video description:

"A 3D animated t-rex drawn on an analogue oscilloscope from 1982, with its redraw frequency modulated by MIDI from ‪@Ableton‬ Live. The amplitude of the audio left & right signals move the X/Y position of the beam which cycles through the vertices of the 3D mesh hundreds/thousands of times a second."

Update via Hexial: "The audio is creating the entire drawing you're seeing, moving the beam across the screen very quickly. The audio frequency is the number of times it's redrawing it per second."

"I'm using 2 synths (Serum) routed into the X and Y axis of the beam, changing pitch/effects with sine waves and saw waves.

Beware, if you listen to it on headphones it might make your brain go weird because it's panned hard left & right 🫠👌"
