Casio CZ-1000 | The Cosmo Synthesizer. Everyone had one of these!

video by Espen Kraft

"The Casio CZ-101, a big hit for Casio in the mid 80s. And the full-size keys, the CZ-1000.
Used by Vince Clarke among others. A best selling synth from Casio back in the day."

Phil A. spotted it in the film and sent in the pic below. I checked the trailer and you can see a couple of them in the background at 1:15. Always curious what the story was behind props like this. You can find more in the Synth Props and the Synth TV and Film labels.

Roland JX-8P VECOVEN Mod - Demoing the arpeggiator, Chord mode and more

video by synthlegends

"Roland JX-8P VECOVEN Mod

In this video I demonstrate the new VECOVEN Mod, you might know from the JX-10 or MKS-70, recently also established fort he JX-8P. I show the main functions, especially the Chord mode and the arpeggiator.

Here partly the description of the Website from Fred Vecoven:

o Chord mode
o Arpeggiator with tons of modes
o each parameter is now OFF/RECV/SEND/ON, allowing fine control of what gets sent and what is filtered.

o sysex support : allow edition of tone parameters individually, including the "patch" parameters.
o midi cc support : allow edition of all tone parameters with midi cc.
o fast bulk dump/load : 1-2 seconds to dump everything. Can dump to/from cartridge and internal memory.
o edition of parameters (patch and tones) sends sysex, so all editions can be sequenced. PG800 is also supported here, so editions made from the PG800 can also be sequenced.
o copy from/to cartridge to create a full backup of the internal memory (all settings are now copied to the cartridge or restored from it)

o flash module provides 32 internal banks (total of 32 x 32 tones = 1024 tones!). Preloaded with hundreds of tones.
o M16C and M64C support : provide one or four extra banks of tones.
o Import mode to load existing internet "dump" files directly into a bank
o any tone parameter can be assigned to the edit slider during play mode [coming soon !]
o control whether updates from sysex, pg800 or controllers are displayed temporarily on-screen
o allows to disable new features for full compatibility with old software (for example, sysex changes made to tone A can be redirected to the currently selected tone, etc...)

This mod is really exciting and the support is great as well. I got the parts within 3 days after ordering.
For the mod soldering is not necessary. There are just two EPROMS to change, which are on sockets.

There is also a PWM mod, but here you have to desolder some IC, but cables are not necessary.
I hope, you enjoy the video and it shall help you to decide about the mod."

Prophet-6 + OB-6 Stacked Together

video by MR TUNA Music

"I recorded this video in 2018 and somehow it never made it to the surface! What a crazy set of sounds these two make together. For this video they are stacked together on the same midi channel separated by an octave.

Just in love with what these two can do together.

I think something really weird happens near the end but I'm not going to watch the video that far today :P

Prophet Vs Prophet - The Blind Test!

video by Alex Ball

Update: results posted here.

"A comparison between a vintage Prophet~5 rev3 and a new Prophet~10 rev4 (both designed by Dave Smith at Sequential).

This is a blind test where you see the same clip twice, but in one you're hearing the Prophet you see and in the other you're hearing the Prophet you don't see.

Write which you think is which for each of the 9 examples in the comments and I'll reveal the correct answers and the results of people's responses in a weeks time.

Huge thank you to Marius Leicht for his help with this video:

Cosmic noise & retro heterodyne: Interstellar Radio

video by Richard DeHove

"If you ever played around with shortwave radio noise as a kid then this is your grownup noise evolution. Schlappi Engineering's 'Interstellar Radio' module wants you to endlessly twiddle and wiggle and enjoy the lack of melody and float away in the squeals and static. With all the controls normalled to produce sound on their own this is also a great module for a small system or someone starting out in Eurorack (assuming you like noise).

Here I go through the basic controls, how to understand a little of what you're doing, and then indulge in lots of wiggling.

AE Modular VACTROL PHASER Audio Demo (no talking) #TTNM


"The tangible waves AE Modular Vactrol Phaser module is an analog phase shifting audio effect for your modular synthesizer. You can add positive or negative feedback, switch between 4 or 8 stages and add internal LFO modulation. Of course external CV modulation is possible too and you get several outputs for the wet signal and individual stages.

Novation Peak demo after 2:15.

"A short description of what VL / digital waveguide synthesis is, and a look at Yamahas implementation in the EX5 workstation, and a demo using only VL sounds using expressive controllers like an EWI and a MIDI guitar pickup, helped bei the MPC One's autosampler.

Table of contents:

00:00 hello
00:38 very short demo
00:59 brief history of digital waveguide synthesis
01:49 how it works
02:20 short, overly simplified demo of the principle using a delay effect and a filter
03:03 creating a VL patch on the Yamaha EX5: reed
03:30 selecting a model (and some sound demos)
04:17 adjusting the model to our needs
04:50 mapping controls to the VL model (volume, pressure, embouchure, scream, growl)
06:50 creating a concert guitar sound
07:49 using MPC One's autosampler to get polyphony
09:51 demo track using only VL instruments

Rebel Technology OWL Max Tutorials


video by vermonagear

"In this video we quickly explain the recent updates regarding the DRM’s connectivity and demonstrate how to generate dynamic trigger signals using a modular environment.
From now on also the analogue trigger inputs are dynamic, same as the midi inputs which provided velocity control ever since. Both the dynamic trigger inputs and midi veloctiy do not just control the output volume of a channel but rather effect the overall excitement of each channel’s circuitry, thus controlling its output volume.

There are different ways to generate dynamic trigger signals. While some sequencers provide it and some don't, in this video we show how to achieve it using modular setup."
