"E-RM presents their new synthesis method! polygogo, E-RM’s new stereo oscillator module, is based on the specially developed polygonal synthesis, a kind of graphical complex amplitude shaping method. With the help of the built-in modulation sources, polygonal synthesis in polygogo opens up a wide range of sonic possibilities from clicky pinged sequences to unique dark thunderstorms, bass lines, leads and colored noise. Max of E-RM presents the current prototype of polygogo in the workshop from 7:30pm and answers questions about the module
See you on Thursday 11th of April – 7:30pm at SchneidersLaden! And if you are planning to start a modular journey, join us for the Modular Beginner Workshop at 6pm.
How to find us:
@SchneidersLaden – Kottbusser Tor above the REWE supermarket (use the door within the REWE entrance – ring the „schneidersladen” bell – and knock LOUD on our metal door on the first floor)"
"Overview and tutorial of the Sequential Circuits Pro One synth. This is a vintage analog monophonic synthesizer from the 80s. I go over each knob and switch and end with a bit of a demo. My keyboard double triggers occasionally and some of the switches are a bit scratchy but it gets better towards the end."

"The Casio CZ-101 synthesizer has a display that can be dim or missing pixels nowadays. Also the original display is hard to read in the dark because it lacks a backlight.
If you want to replace it with a LED backlight LCD, you run into 2 problems: most LCD's are on smaller boards, and the frame is thicker because there is a backlight under the screen.
Today I replace the LCD in a Casio CZ-101 with a nice new OLED display that exactly matches the original dimensions, works straight out of the package, and has a nice unlimited viewing angle and stellar contrast. You can get these screens in various colours, but I chose yellow because I think it matches the yellow waveform and CZ-101 logo print on the case.
Used Display:
Electronic Assembly W162-XLG in greenish yellow 84x44mm."

Reassembling a Casio CZ 101 after repair

"I bought a 'for parts' Casio CZ-101 and hoped for an easy fix. It wasn't. Luckily someone reacted to my classifieds ad with a request for a new main PCB. Then I swapped the main board and got sound. But things were not that easy. The screen was missing lots of lines and pixels. And 3 buttons and 6 keys weren't working: it turned out a PCB trace was broken, and that 2 wires in the flat cables were broken. And off course I did a thorough cleaning.
But finally I got everyting to work, and I managed to install a nice new perfect fit OLED display in a nice yellow colour matching the print on the case. The result: a near mint working Casio CZ. This awesome sounding synth deserves to be preserved and repaired! Don't bring them to recycling but fix it or share parts to others trying to keep their CZ synts alive!
This video is a quick montage, I left out the full transcription I usually make because of the length of the video. If you want to see all the details, watch on a big screen, I recorded 4K to grab all details."
This module is based on ideas presented in Electronotes #132. It is a VCF with a 'filter exciter' section to allow a wide variety of acoustic, semi-acoustic and not-acoustic-at-all sounds. In a sense it takes the concept of pinging the LPG or ringing a VCF one step (or 2) further. The decaying sound is fed back into the input via a VCA. The VCA can be controlled by a gate or an envelope (or both).
Another interesting point is higher frequency sounds tend to be louder.....which is what happens naturally in the big room."
"I hope this video serves to give some ideas of not only the possibilities of Complex-1 but also to give you some ideas to try things in other software and hardware synthesis (modular or otherwise). In this patch I go through create stereo synth tones, sequenced arpeggios, FX, folding and a whole load of patching. Check out the full Complex-1 tutorial/demo here"
